[0013] A floating machine control system 1 which is an embodiment of the present invention has a floating machine 100 and a ground station 200 as shown in FIG. 1. The floating machine 100 is a flying object that floats in the atmosphere and can move in three-dimensional directions. The ground station 200 is a system that includes a computer, communicates with the floating machine 100, sends a control signal to the floating machine 100, and controls the operation of the floating machine 100. The ground station 200 may control a plurality of floating machines 100. The floating machine 100 is capable of autonomous navigation.

[0014] <Explanation of the floating machine> The floating machine adopts a technology that efficiently utilizes the jet stream in the stratosphere and obtains propulsion force from natural phenomena. Therefore, it has the following elements. a. Buoyancy ensuring device (lifting device) It has a high-performance airbag system that adjusts the internal pressure in real time to precisely control the altitude. b. Propulsion device It is equipped with a small and highly efficient propeller to achieve propulsion movement in the air, precise position adjustment, and course change. c. Energy supply system It combines a solar panel and a high-efficiency battery to enable long-term energy supply and long-term floating. d. Navigation control system The system incorporates an AI (Artificial Intelligence) control system that analyzes weather data in real time and calculates the optimal travel route to the destination by utilizing air currents. Alternatively, some functions of the navigation control system may be provided by a ground station, which can send sensor values ​​and other information via communication. The received control signals can then be used to control buoyancy control devices, propulsion systems, and other components. e. Communication Systems It is equipped with a communication system that enables real-time communication with the ground and inter-aircraft communication. f. Functions according to application It is equipped with devices and functions suited to applications such as weather observation, environmental monitoring, disaster response, logistics and transportation, and communication relay. The buoyancy control device and propulsion device function as a floating motion execution device.

[0015] Let's explain each component in detail. a. Buoyancy ensuring device The buoyancy control device consists of the following components: • Air sac (balloon): The outer shell of the gas sac is constructed of polyethylene with a multi-layer film structure or nylon with a special coating. This outer shell has the strength and flexibility to withstand external pressure changes and temperature fluctuations while containing helium gas. It is also specially treated to withstand ultraviolet rays and extreme temperature environments. The gas inside the gas sac expands as the external pressure decreases with ascent. The outer shell is designed to expand from a deflated state or unfold from a folded state to become large enough to accommodate the expanded gas. • Helium supply system: The helium supply system consists of a high-pressure tank, an electric valve, and a piping system. This system manages the amount of helium (filling volume) supplied to the gas bag in real time, maintaining appropriate buoyancy. The high-pressure tank is made of a corrosion-resistant lightweight alloy, and the electric valve's opening and closing are precisely controlled by a control device. Helium is a gas that is about seven times lighter than atmospheric air, and one cubic meter of helium can generate about 1.1 kg of buoyancy. Therefore, for example, using a 10 cubic meter gas bag will provide a total buoyancy of about 11 kg, using a 100 cubic meter gas bag will provide a total buoyancy of about 110 kg, and using a 1000 cubic meter gas bag will provide a total buoyancy of about 1100 kg. The amount of buoyancy remaining after subtracting the weight of the aircraft structure, control system, batteries, propulsion system, etc., is available as payload. • Pressure adjustment mechanism: The pressure regulation mechanism is a system that works in conjunction with real-time sensors to respond to changes in external atmospheric pressure. This mechanism continuously measures the difference between the external and internal pressures and adjusts the injection or release of helium to prevent excessive expansion or contraction of the gas bag. This mechanism ensures that the gas bag always maintains its optimal shape and internal pressure. Furthermore, the high-pressure tank of the helium supply system does not encompass the entire volume of the gas bag (balloon), and it can also function as a pressure regulating mechanism that allows for gas supply and recovery between the gas bag and the tank. In other words, when refilling the gas bag, gas is moved from the tank to the gas bag, and conversely, when removing gas from the gas bag, the gas is drawn out of the gas bag and transferred to the tank under pressure. This allows the tank to be made lighter by using a low-pressure tank corresponding to the amount of gas being moved. • Internal gas distribution piping: The internal gas distribution piping is a device designed to evenly distribute helium gas within the gas bag. This piping is constructed from a highly pressure-resistant, flexible material, preventing localized uneven distribution of helium concentration. It also plays a role in maintaining uniform buoyancy throughout the entire gas bag. • Reinforcement frame: The reinforcing frame is a lightweight, high-strength structure made of carbon fiber, such as carbon fiber or graphene-reinforced plastic, that maintains the shape of the airbag and provides resistance to external impacts. This frame is located inside the airbag and improves the overall stability of the buoyancy control device.

[0016] These components, working together, enable the buoyancy control system to achieve stable floating and altitude control in the stratospheric environment.

[0017] Furthermore, instead of relying solely on the gas bags mentioned above for all buoyancy, the thrust of the propellers described later may also be used. Alternatively, the system may use gas bags to ascend to a certain altitude, and then utilize a hybrid buoyancy system with propellers and lift. In addition, even if gas bags are present, buoyancy may be obtained solely from the thrust of the propellers without using their buoyancy. Alternatively, the system may be configured to obtain buoyancy solely from the thrust of the propellers without using gas bags. In particular, the weight of the helium supply system can easily become a burden in small flotation devices. Alternatively, hydrogen may be used for the helium supply system. In that case, since hydrogen is highly flammable, safety measures must be taken. The gas bags can be covered with flame-retardant materials to prevent static electricity and sparks, or the hydrogen can be dispersed into multiple small gas bags to localize the risk in case of damage.

[0018] b. Propulsion system (propeller) The propulsion system is equipped with multiple small propellers, each driven by a highly efficient brushless motor. The system employs a drone-like structure with four propellers, and each propeller is individually controlled. The propulsion system mainly consists of the following elements: • Brushless motor: Brushless motors are characterized by their lightweight, high efficiency, and low maintenance. Each motor has a built-in sensor that can acquire data such as rotational speed, load, and temperature in real time. This allows the AI ​​control unit to precisely adjust the thrust. ·propeller: The propellers are designed with lightweight carbon fiber and composite materials, achieving both high strength and low weight. The blade shape is optimized for low-density air at high altitudes, providing efficient thrust. Furthermore, the propeller size and rotation speed are adjustable, allowing for adaptation to various altitude conditions. Features include variable-pitch propellers that adjust the propeller pitch (angle) according to altitude, a dual-propeller system that can be switched depending on altitude, and a wide-bladed propeller design to achieve sufficient thrust even in thin air layers. • Propeller mounting mechanism: Each propeller is mounted on a movable arm, allowing for 360-degree angle adjustment. This mobility allows for flexible changes in the direction of thrust, enhancing the aircraft's stability and directional control. • Motor drive circuit: A highly efficient inverter circuit is employed to provide precise power to the brushless motor, resulting in improved motor efficiency and durability.

[0019] Challenges and solutions in high-altitude environments: Incidentally, at high altitudes, low temperature, low pressure, and low density air significantly affect the performance of the propulsion system. To address this problem, this embodiment has the following technical features. First, it employs a motor that can operate even in low-temperature environments, and the internal lubricant has the characteristic of maintaining viscosity even at low temperatures. In addition, low-temperature resistant materials are used for the motor and circuit board, and a heater is incorporated as needed to maintain a constant operating temperature. Furthermore, to overcome the thrust deficiency in low-density air, the propeller shape has been aerodynamically optimized, employing a design that efficiently captures air. The propeller rotation speed is adjusted in conjunction with the motor output, providing sufficient thrust even in low-density environments. In addition, a highly efficient inverter circuit is used in the motor drive circuit, enabling stable operation while minimizing energy consumption.

[0020] Adaptation to low-temperature environments: To ensure proper functioning of the motor and circuitry at high altitudes and low temperatures (below -70°C), the motor is designed to maintain an appropriate temperature by incorporating a heating mechanism inside. This heating mechanism operates with the minimum energy required for motor operation and is designed to prevent friction and power supply issues even in low-temperature environments. Furthermore, the circuit board uses low-temperature resistant materials, making it a structure that can withstand extreme temperature changes. This enables long-term operation and maintains stable performance at high altitudes.

[0021] c. Energy supply system The energy supply system consists of solar panels located on the top of the aircraft and high-efficiency batteries. • Solar panels The solar panels absorb sunlight during the day to generate electricity, using a portion of it immediately and storing the remainder in a battery (energy storage device). At night or on cloudy days, power is supplied from the battery, ensuring that the aircraft's operation is not interrupted. Examples of lightweight solar panels: Lightweight and highly flexible solar panels using perovskite-type solar cells are integrated into the wings, fuselage, and balloon section of the floating aircraft. • Folding and rolling mechanism It features a folding and rolling mechanism to optimize energy efficiency during ascent and descent. During ascent and descent, the solar panels are folded or rolled in multiple stages to minimize air resistance. Deployment is performed by an automatic mechanism using a motor or shape memory alloy. When deployed, it becomes a wing, making it easier to catch the airflow.

[0022] Solar cells used include CNT electrode solar cells, perovskite solar cells, organic thin-film solar cells (OPVs), CIGS solar cells, quantum dot solar cells, III-V compound solar cells, carbon-14 diamond cells, and vertical solar power poles. CNT electrode solar cells are suitable for use because they offer an excellent balance of lightness, durability, and temperature characteristics. For the purpose of weight reduction, perovskite solar cells, organic thin-film solar cells, and tandem solar cells may be used. Although expensive, III-V compound solar cells and carbon-14 diamond cells may also be used from the standpoint of durability and temperature characteristics.

[0023] d. Navigation control system The navigation control system consists of a navigation control AI and a group of sensors, enabling real-time adjustment of altitude, position, and course. The sensor array includes a barometric pressure sensor, an accelerometer, and a GPS positioning sensor. These sensors collect atmospheric pressure, acceleration, and location information (latitude, longitude, and altitude), and transmit this data to the navigation control AI. The navigation control AI analyzes this data to set the optimal altitude and thrust. Furthermore, by incorporating weather data, it can adapt to changes in the external environment. Navigation control AI may be installed directly inside the floating vehicle or located at a ground station. External cloud-based AI or generative AI can also be utilized. When the navigation control AI is installed outside the floating vehicle, it transmits control commands while communicating with the vehicle. This allows for flexible system design tailored to the environment.

[0024] To control the movement of such floating devices, the navigation control AI is designed to learn the following and perform appropriate control based on this learning. This technical design utilizes deep learning and reinforcement learning, which are used in AI technology, enabling advanced control in complex environments. Furthermore, when using generative AI such as OpenAI's CHAT-GPT or Google's Gemini, a mechanism is designed to enable integrated control based on data input from sensors and feedback to the control system. The generative AI contributes to operation through the following process. In addition, when using general-purpose generative AI such as CHAT-GPT, its range of applications can be expanded by integrating it with specialized control algorithms.

[0025] First, in analyzing meteorological data, the navigation control AI learns from weather satellite and ground observation data and has the ability to predict the speed, direction, and altitude of jet streams and local currents. In this case, the generative AI can play a role in augmenting the prediction model by analyzing real-time meteorological data. In particular, it needs the ability to quickly detect turbulence and weather changes and reflect them in the movement route and altitude adjustment of the flotation device. Furthermore, in order to enable dynamic altitude adjustment, it also has the ability to learn how to operate the buoyancy control device and make real-time altitude adjustments in response to changes in external pressure and temperature.

[0026] Furthermore, in the precise control of the propulsion system, the navigation control AI learns the operating patterns of the propellers and propulsion motors, enabling accurate course correction to the destination. The generative AI generates optimization patterns based on vast amounts of operating data and proposes algorithms applicable to the actual control system. This includes complex control involving fine-tuning. In addition, in energy management, it has the capability to efficiently manage the energy supply from solar panels and batteries, enabling stable operation day and night.

[0027] In addition, in communication control and data analysis, the navigation control AI has the capability to manage communication between the floating vehicle and the ground station and send and receive data in real time. Particularly important is the flow of outputting control commands as feedback through inference by the generative AI from sensor data input. Specifically, data such as atmospheric pressure, temperature, and wind speed acquired by sensors are provided to the generative AI, which analyzes this data to calculate optimal control commands such as altitude adjustment and propulsion output adjustment. These commands are transmitted to the floating vehicle's control unit and reflected in real time. The generative AI also contributes to error correction of communication data and selection of the optimal communication route, assisting in maintaining communication stability. It is trained to select the optimal frequency band according to the environment. In this way, by combining the generative AI with existing control AI, it is possible to contribute to more complex data analysis and prediction, further improving the operational accuracy and efficiency of high-altitude floating vehicles.

[0028] Examples of commands for AI: For example, commands to the AI The problem could also be phrased as: "Find the optimal route from your current location (latitude, longitude, and altitude), determined from your current location (latitude, longitude, and altitude), to the set destination (latitude, longitude, and altitude), utilizing air currents. Determine the air currents by analyzing past and current weather data." Furthermore, additional commands can be given to the AI, such as "The optimal route is one that allows for more stable flight, such as avoiding turbulence," or "The optimal route is one that can be reached in the shortest amount of time." Alternatively, to keep the AI ​​in a certain area, you could give it a command such as, "Find a route that allows it to stay in a certain area by riding the air currents and circling around it." Furthermore, to conserve energy, you could instruct the AI ​​to "include the amount of electricity generated based on the duration (amount) of sunlight exposure in its calculations, and find the most energy-efficient route to the destination." Furthermore, you could also give the AI ​​a command such as, "Find an emergency route to evacuate to a safe area, avoiding dangerous weather conditions predicted from your current location (typhoons, storms, extreme cold areas)." Furthermore, when visiting multiple destinations, the command to the AI ​​could be: "Given multiple destinations (latitude, longitude, altitude), find the most efficient route to visit each of them, and travel in the shortest time or with the least energy consumption." Furthermore, as an instruction that includes altitude changes, the command to the AI ​​could be: "Analyze current weather data and air currents around the destination, and if flight at a specific altitude is efficient, instruct the AI ​​to ascend or descend to that altitude." Furthermore, for observation and data collection in a designated area, it is also possible to issue commands to the AI ​​such as, "Stay in the designated area for an extended period (e.g., ** hours) and collect weather and environmental data using observation equipment. Adjust the route so that communication with the ground station is not interrupted." Furthermore, for stable flight at a fixed point, the AI ​​can be instructed to "find a route that maintains stable, fixed-point hovering at the specified location for a certain period of time. Adjust buoyancy and thrust appropriately, taking into account airflow fluctuations, to minimize energy consumption." Furthermore, considering the balance required for long-distance travel, it would be appropriate to give the AI ​​instructions such as, "Plan your journey to your destination while optimizing energy consumption, taking into account the remaining battery level and the performance of the propulsion system." Furthermore, to ensure communication stability, the AI ​​may be instructed to "calculate a route that is only possible within the communication area and prevent communication interruptions." In this case, it is assumed that the communication area has been pre-programmed into the AI. Furthermore, for operations including the delivery of cargo, it would be possible to issue a command to the AI ​​such as, "Calculate a safe route for delivering cargo at the designated location, and maintain stable buoyancy while minimizing energy consumption." Furthermore, to improve the accuracy of weather data analysis, the AI ​​may be instructed to "move while collecting weather observation data and continuously update the database so that it can be reflected in the next route calculation." The floating vehicle is equipped with various sensors for collecting weather observation data, and the AI ​​(navigation control AI) is assumed to be able to acquire this data. Furthermore, to accommodate special applications including disaster response, the AI ​​may be instructed to "calculate a dwelling route over the disaster area and immediately adjust its altitude and position based on the local conditions." It should be assumed that the AI ​​has pre-programmed data regarding the disaster area.

[0029] Thus, the navigation control AI plays a role in achieving highly accurate operation of the floating vehicle by integrating and managing weather data analysis, dynamic altitude adjustment, precise control of the propulsion system, energy management, and communication control.

[0030] <Route search using algorithms> Furthermore, navigation control systems can perform route searching without necessarily using AI such as machine learning or deep learning.

[0031] The following describes a route search method that utilizes Dijkstra's algorithm and other methods to find the optimal route for a floating device to reach its destination by riding air currents.

[0032] This route-finding method models airflow at various locations on Earth as "links" and constructs a "network" by connecting these links. Each link is assigned a start and end point defined in three-dimensional space, and a "cost" required for travel along the link is calculated and assigned. This cost is evaluated by combining multiple factors, including airflow speed, safety, presence or absence of turbulence, energy consumption, and the time required for travel. This results in the construction of links that accurately reflect the characteristics of the airflow.

[0033] The cost calculation utilizes historical weather data, real-time weather observation data, and weather forecasting models. This dynamically updates the characteristics of each link (e.g., airflow stability, speed, safety, etc.), including the time axis. Using this constructed airflow network as input data, an optimal route search is performed using known methods such as Dijkstra's algorithm.

[0034] Dijkstra's algorithm sets a starting point as a node (latitude, longitude, altitude) and searches for the optimal route to the destination node. The search proceeds by selecting the shortest cost link from the starting point. During this process, cumulative cost is considered, and the path that minimizes the overall cost is dynamically calculated. Cumulative cost includes the following elements: • Travel time based on airflow speed and direction • Safety assessment based on airflow stability and the presence or absence of turbulence. • Energy efficiency considering the amount of electricity generated by solar panels and the remaining battery capacity. • Risk assessment in cases where emergency evacuation is necessary.

[0035] This allows the navigation control system to dynamically calculate the route to reach the destination. For example, if the shortest travel time to the destination is the priority, a link with high air current speed is selected. On the other hand, if energy conservation is the priority, a route that uses air currents with low energy consumption, even at a lower travel speed, is chosen. Thus, a key feature is the ability to flexibly change the cost weighting according to the purpose of route searching.

[0036] Furthermore, the system can adapt to real-time changes in weather conditions. For example, if turbulence occurs along the route to the destination, the cost of the link is dynamically recalculated, and a new route is searched for. This allows the flotation device to reach its destination efficiently while maintaining safety.

[0037] Furthermore, the cost of the link also reflects the impact of airflow on power generation efficiency. Specifically, the calculation includes the altitude and time of day when the solar panels can generate the most power. Based on this information, a route that minimizes energy consumption can be selected. Such route planning is particularly useful when the floating vehicle is to be operated for extended periods.

[0038] The following scenarios are possible application examples. (1) Disaster response To efficiently move over the disaster area and deliver supplies quickly, routes prioritizing safety and speed are being searched. (2) Environmental monitoring When conducting weather observations and collecting air pollution data, the system calculates the optimal stagnation route within a specified area while minimizing energy consumption. (3) Logistics applications The system calculates efficient routes that circulate through multiple distribution centers, minimizing overall operating costs.

[0039] This route planning method offers significant advantages over conventional flight planning technologies, particularly in its ability to flexibly adapt to complex weather conditions and diverse operational requirements. This enables the aircraft to achieve optimized movement in terms of safety, efficiency, and energy consumption, making it promising for use in a wide range of fields, including observation, logistics, and disaster response.

[0040] Furthermore, the navigation control system may instruct the navigation control AI to use the route search algorithm described above. For example, for a navigation control AI, there are steps such as analyzing past and current weather data to evaluate the characteristics of airflow and modeling the airflow as a link, Regarding the aforementioned link, the steps include evaluating the required time, safety, and energy consumption as costs, The system is instructed to perform a route search, which includes a step of calculating the route with the minimum cumulative cost based on the evaluated costs, using Dijkstra's algorithm. Alternatively, in order for the floating device to orbit and remain within a specific range, the navigation control AI is instructed to analyze the airflow characteristics within the specified range based on weather data and to search for a route that can be followed based on the stability of the airflow.

[0041] e. Communication Systems The communication system is configured to enable real-time communication with the ground and inter-aircraft communication. The components of the communication system are as follows: • High-power wireless module High-power radio modules form the core of communication systems, enabling wide-area data transmission and reception. This ensures communication with ground stations and other aircraft. • Multi-band compatible antenna A multi-band antenna has the function of supporting multiple frequency bands in a communication system, and achieves efficient communication by automatically selecting the optimal frequency band according to the surrounding communication environment. • Communication protocol control unit The communication protocol control unit performs controls to maintain the stability and efficiency of communication. This unit monitors the transmission and reception of data and has a mechanism to automatically retransmit data when an error occurs. • Satellite communications module The satellite communication module is installed because communication from the ground may be difficult in high-altitude environments. This module enables reliable communication even in remote locations. • Encryption function The encryption function applies strong encryption to communication data as a security measure. This prevents unauthorized access from external sources and protects confidential information.

[0042] The communication system collects data from the aircraft's sensors and navigation control AI and transmits it to ground stations and other aircraft. When real-time communication is required, high-power radio modules and multi-band antennas are activated, using the most suitable frequency for the environment to transfer the data. Furthermore, the communication protocol control unit monitors the quality of transmitted data and retransmits it if errors or communication interruptions occur. In addition, if a satellite communication module is connected, data transmission is possible even outside the communication range. All communication data is highly protected by encryption, minimizing the risk of external eavesdropping and tampering.

[0043] Such communication systems transmit and receive data with ground stations and other floating aircraft, sharing operational information in real time. They also feature a relay function utilizing satellite communication, enabling operation over a wide area.

[0044] f. Functions according to application The flotation device of this embodiment can achieve a variety of purposes by equipping it with the necessary devices according to each of the following applications.

[0045] • Weather observation The device is equipped with temperature sensors, humidity sensors, barometric pressure sensors, anemometers, wind vane meters, and optical sensors for cloud cover measurement, all necessary for meteorological observation. These sensors collect meteorological data from the stratosphere and near the ground with high accuracy. Furthermore, it has a built-in AI processor for data analysis, enabling real-time analysis of the observed data.

[0046] • Environmental monitoring For environmental monitoring, the system will be equipped with sensors to detect particulate matter and harmful substances in the atmosphere (PM2.5, carbon monoxide, nitrogen dioxide, ozone, greenhouse gases, etc.). In particular, chemical sensors and laser spectrometers will be used to achieve wide-area and highly accurate measurements. Furthermore, a large-capacity data storage device will be installed to record global environmental changes over long periods.

[0047] Disaster response For disaster response, its ability to float for extended periods allows it to be equipped with communication relay equipment, relief supply containers, infrared cameras, and high-resolution visible light cameras. The communication relay equipment will ensure communication between the disaster area and the outside world using satellite and wireless communications, even if ground communication infrastructure is destroyed. It will also be equipped with a robotic arm and automatic release mechanism for transporting and dropping relief supplies (including leaflets), a loudspeaker for voice announcements, and LED lights.

[0048] ·Logistics / Transportation Logistics and transportation require container securing devices and shock-absorbing structures to transport cargo safely and efficiently. Load sensors and cameras are also necessary to monitor the weight and condition of the cargo in real time. Furthermore, integrating navigation AI and energy management systems to optimize the route to the destination maximizes transportation efficiency.

[0049] • Communication relay For communication relay purposes, the system is equipped with a high-power wireless communication module, a multi-band antenna, and a satellite communication unit. This enables data communication with the ground and provides a wide-area communication network. Furthermore, encryption modules and data backup devices are included to ensure security.

[0050] As described above, the floating device in this invention can be operated for a wide range of purposes by equipping it with devices suited to various applications such as weather observation, environmental monitoring, disaster response, logistics and transportation, and communication relay. These devices maximize the operational efficiency of the floating device and demonstrate high performance under various conditions.

[0051] <Explanation of an example of a levitation device using diagrams> Several examples of floating devices will be explained using diagrams. Figure 2 shows an example of the floating device 100A, illustrating the arrangement of each component in the floating device 100A. The floating device 100A in this embodiment includes a solar panel 102A installed in the center of the main body 101A, balloons (inflated state) 103A arranged in four directions, and propellers 104A attached to the top of each balloon.

[0052] Solar panel 102A functions as the primary energy source for the floating machine 100A and employs a structure that efficiently absorbs sunlight by securing a large surface area. This solar panel 102A generates electricity using daytime sunlight, supplying power to the floating machine 100A's propulsion system and communication system. Furthermore, any surplus electricity generated is stored in a battery, enabling operation at night and on cloudy days.

[0053] The balloons 103A, positioned in four directions, are elements that ensure the buoyancy of the float 100A. These balloons 103A are filled with helium gas and are designed so that each balloon 103A can independently adjust its buoyancy. This structure allows the float 100A to maintain altitude while maintaining a stable attitude.

[0054] Propeller 104A functions as the propulsion system for the floating machine 100A, controlling its movement and position. Each propeller 104A is mounted on top of the balloon 103A and is designed to be lightweight and highly efficient. Each propeller 104A is individually controlled, allowing for changes in the machine's direction and fine adjustments. Energy consumption associated with the operation of the propulsion system is covered by power supply from solar panels and batteries.

[0055] Furthermore, the frame to which the propeller 104A and balloon 103A are attached is foldable using an adjustable opening / closing wire 105B. This allows the overall size to be changed and air resistance to be controlled.

[0056] As shown in this figure, the flotation device of the present invention enables efficient and stable floating and movement through the coordinated operation of the buoyancy securing device and the propulsion device. Furthermore, sustainable energy supply using solar panels 102A allows for long-term operation. In addition, the four-directional balloon arrangement shown in the figure optimizes the center of gravity balance of the flotation device and enhances its stability.

[0057] Figure 3 shows an example configuration of the floating device 100B, which includes a deployable solar panel 102B attached to the main body 101B and a balloon (balloon section) 103B. In this figure, the solar panel 102B is depicted in a partially deployed state, clearly illustrating how this improves the energy efficiency and functionality of the floating device 100B.

[0058] The buoyancy device 100B of this embodiment has a balloon 103B positioned in the center and foldable solar panels 102B surrounding it. The balloon 103B is the main element that generates buoyancy and plays a role in maintaining the altitude of the buoyancy device by filling it with helium gas. This balloon is made of a material that combines strength and flexibility and is designed to withstand changes in external air pressure and temperature.

[0059] The solar panel 102B is a critical component of the energy supply system of the floating machine 100B. This figure shows the panel partially deployed, allowing for maximum capture of sunlight. This deployable solar panel is equipped with an opening / closing wire 105B for transitioning from a folded to a deployed state, enabling efficient deployment or retraction as needed. Furthermore, its deployed shape is flexibly adjustable, accommodating configurations such as rolled or tiled arrangements. This allows for operation in an appropriate shape depending on transportation and the operating environment.

[0060] Multiple propellers 104B are positioned around the balloon, functioning as a propulsion system. Each propeller is individually controllable, allowing for precise direction and position adjustment of the floating device. The propellers are powered by electricity generated by solar panels and stored in batteries.

[0061] In this configuration, the solar panel 102B has a deployable structure that allows for a large surface area, making it possible to efficiently utilize daytime sunlight to generate electricity. Furthermore, by storing surplus power in a battery, a stable energy supply is possible even at night or on cloudy days. In addition, when the panel is folded, air resistance is reduced, improving the efficiency of the levitation device when it ascends or moves.

[0062] The deployable structure shown in this figure offers flexibility to accommodate a variety of applications, including long-term floating, observation, and communication relay. Furthermore, the overall design, including the opening / closing wire 105B and the propeller control mechanism, is optimized to ensure that the floating machine 100B maintains a stable attitude while achieving high-precision operation.

[0063] Based on the above, the configuration shown in this figure demonstrates that the flotation device of the present invention exhibits excellent performance in terms of energy efficiency, maneuverability, and safety.

[0064] Figure 4 shows an example of a structure in the floating machine 100C in which the solar panel 102C attached to the main body 101C is rolled into a cylindrical shape. This shape is designed to generate efficient speed when moving in a straight line. In addition, by making the direction of the propeller 104C variable, it has the flexibility to control thrust and buoyancy simultaneously.

[0065] In this configuration, the solar panel 102C is housed in a cylindrical shape in the center, making it suitable for use when not in use or when minimizing air resistance is desired. This cylindrical panel has a layer on its inner surface that absorbs sunlight, and it is also possible to use both sides. Deployment wires 105C are used to house and deploy the solar panel, and it can be deployed automatically or remotely as needed.

[0066] Furthermore, the levitation device 100C is equipped with four propellers 104C, each designed to be individually controllable. This allows the levitation device to precisely control not only forward, backward, left, and right movement, but also direction changes and altitude adjustments. The main control unit adjusts the propeller angles to provide optimal thrust according to the direction and speed of movement. In addition, the main body 101C extends its wings like an airplane to facilitate horizontal movement and to easily utilize the lift generated by the wings.

[0067] Figure 5 shows the solar panel 102C, which was rolled into a cylindrical shape in Figure 4, in an unfolded state. Here, the solar panel 102C is pulled out by the unfolding wire 105C, achieving a shape that can efficiently absorb sunlight over a wide area.

[0068] The deployed solar panel 102C covers a large area, enough to enclose the entire floating device 100C, allowing for maximum utilization of daytime sunlight. This significantly improves the efficiency of the energy supply system and enables long-term operation. The solar panel is constructed from lightweight and flexible materials and is designed to withstand wind pressure and weather conditions.

[0069] Furthermore, Figure 5 shows a transparent balloon 103C positioned in the center, filled with a gas that generates buoyancy (e.g., helium). This balloon is an important component that supports the altitude maintenance and attitude stabilization of the flotation device 100C. The transparent material allows sunlight to irradiate the solar panel 102C. The transparent material was selected to reduce weight while minimizing the influence of the external environment.

[0070] The propeller 104C is positioned around the outer perimeter of the deployed solar panel 102C, providing stable thrust and position control. The propeller's placement and angle are designed to ensure efficient operation even when the solar panel 102C is deployed.

[0071] The floating device 100D shown in Figure 6 has a structure in which a solar panel 102D is attached to the outer surface of a balloon 103D and integrated into one unit, and is characterized by a design that simultaneously achieves buoyancy and energy supply. The balloon is filled with helium to provide buoyancy, and the solar panel 102D on its outside generates electricity efficiently. This integrates the buoyancy structure and the energy supply device, improving both weight reduction and efficiency.

[0072] As an example of the configuration of the floating device 100E shown in Figure 7, the solar panel 102E is shown in a mountain-like shape on top of the main body 101E of the floating device. In this configuration, a balloon 103E is enclosed in the center, and a design is adopted to absorb sunlight over a wide area while ensuring buoyancy. The solar panel 102E is deployed in a mountain-like pattern on the outside of the balloon 103E, designed to efficiently absorb sunlight. The deployed panel is made of lightweight and flexible material, making it adaptable to wind pressure and weather conditions. During the day, it collects sunlight over a wide area, maximizing energy efficiency to supply the power needed for the float's propulsion system and communication systems.

[0073] Figure 8 shows an example of a configuration using a foldable solar panel 102F in the floating machine 100F. In Figure 8, the solar panel 102F is depicted in a folded state, reducing air resistance while maintaining a compact shape and enabling efficient operation. The solar panels are attached to the main body 101F of the levitation vehicle and are designed to be deployed when in use and folded when not in use or during transport. This folding mechanism operates using deployment wires 105F, allowing the panels to be deployed or stored automatically or remotely as needed. Energy collection efficiency is optimized by providing a layer that absorbs sunlight on one or both sides of the panels.

[0074] By employing the foldable solar panel 102F, the levitation vehicle 100F minimizes air resistance during movement and transport, while enabling power generation over a wide area when deployed. This results in improved energy efficiency and operational flexibility.

[0075] Figure 9 shows a configuration in which two floating units 100G are connected by a connecting unit 106G. In this connection example, the integration of multiple floating units allows for larger size and improved stability. This configuration makes it possible to increase the amount of cargo that can be transported and to efficiently conduct observations over a wide area.

[0076] Figure 10 shows the configuration of the flotation device 100H with a ring-shaped balloon 103H. In this design, the balloons 103H are arranged in a ring, efficiently securing buoyancy while enabling stable flight.

[0077] The annular balloon 103H not only provides buoyancy, but can also incorporate a solar panel function on its outside or inside. This solar panel 102H efficiently absorbs sunlight and generates electricity. Furthermore, the balloon 103H is fitted with a curl spring 107H, which automatically folds inward if the internal pressure of the balloon 103H decreases. This allows for a more compact float 100H and protects the balloon 107H.

[0078] Figure 11 shows a configuration in the floating device 100J that includes an up-and-down movement mechanism using a balloon 103J and an extension cable 108J to enable the transport and transfer of cargo. This levitation device 100J has a balloon 103J supported at the top by a balloon support 1931J, and a solar panel 102J is installed on the balloon 103J. The solar panel 102J is either directly attached to the surface of the balloon 103J or installed covering the balloon 103J, and it serves to supply power to the entire levitation device 100J. The balloon 103J is designed to be inflatable and provides buoyancy by being filled with a lightweight gas (e.g., helium) to maintain the altitude of the aircraft.

[0079] The balloon 103J and the main unit 101J are connected by an extension cable 108J. A mechanism for winding up this extension cable 108J allows the balloon 103J to be raised and lowered while floating. This function enables stable floating at specific altitudes and efficient cargo transfer.

[0080] The main body 101J is fitted with four propellers 104J, which are responsible for the thrust and attitude control of the entire 100J flotation device. The main body 101J is also equipped with a "cargo locking mechanism (clamping arm) 109J" and "landing gear," allowing for safe cargo retrieval and securing. The cargo transfer clamp 111J has a function to measure the load and a safety design that sounds an alarm and refuses to accept cargo if it is overloaded.

[0081] The balloon 103J has a connecting section 106 at its top, allowing it to be connected to other aircraft. In this case, the cargo transfer clamp 111J of the other aircraft also functions as a connecting section, allowing them to be connected vertically. By connecting them, it becomes possible to transport heavier loads.

[0082] This configuration allows the floating vehicle to be used for transporting supplies and conducting observation activities over a wide area, making it particularly suitable for use during disasters or in areas with limited access. Furthermore, the combination of the balloon and solar panels enhances energy efficiency, enabling sustainable operation.

[0083] Figure 12 shows a configuration in the floating device 100K where the way light hits the solar panel 102K is optimized by moving the balloon 103K up and down, thereby achieving efficient energy absorption.

[0084] The 102K solar panel is installed on top of the 101K main unit and is designed to absorb sunlight over a wide area. By adjusting the length of the 108K extension cable to move the 103K balloon up and down, it is possible to prevent light from being blocked from the solar panel and capture sunlight at the optimal angle. This maximizes power generation efficiency and supports the long-term operation of the 100K floating device. This configuration allows the 100K floating device to achieve both optimized energy efficiency and floating stability, making it suitable for a variety of applications such as observation, communication, and logistics. Furthermore, the ability to move the balloon section enables flexible operation in response to environmental conditions.

[0085] <Advantages of the levitation device> Floating aircraft, with their jellyfish-like floating characteristics, have unique applications that conventional aircraft and balloons cannot achieve. They can move naturally by utilizing air currents on Earth, and their flexibility and long-term flight capabilities allow for versatile operation. These floating devices are ideal for weather observation and environmental monitoring. Because they move with air currents, they can automatically cover a wide area. For example, by equipping them with sensors to measure the concentration of airborne particles and gases, it becomes possible to collect environmental data on a global scale. Furthermore, even when fixed-point observation is required, stable data acquisition can be achieved by analyzing air current characteristics and gently orbiting the surrounding area. Next, these floating devices can also be used for observation and communication relay during disasters. If ground infrastructure is destroyed, the floating devices can function as a platform to temporarily provide a communication network. In particular, by having multiple floating devices work together, it becomes possible to build a flexible network that covers the entire disaster area. Furthermore, these floating machines can offer unique experiences in the fields of education and tourism. For example, by broadcasting the stratospheric floating experience in real time, educational institutions can provide opportunities to learn about the global environment. In tourism applications, cameras mounted on the floating machines can record breathtaking scenery, offering a new experience of viewing the Earth from above. Furthermore, the key features of these floating devices are their low operating cost and sustainability. Because they move naturally by riding air currents, they can operate over a wide area while minimizing energy consumption. This characteristic makes them suitable for use in remote areas and developing regions, and they are attracting attention as a solution for observation and logistics in places where infrastructure is not well-developed. Thus, these floating machines, capable of drifting freely in the atmosphere, are expected to be utilized in a variety of fields, leveraging their unique characteristics. This technology, which combines flexibility and sustainability, holds the key to opening up new possibilities for use.

[0086] <Ground station description> The ground station serves as the central hub of the floating machine control system of the present invention and consists of multiple elements necessary for communicating with the floating machine and controlling its operation. This station is equipped with the following elements to enable real-time management of the floating machine. a. Communication control unit The communication control unit has the central function of managing data transmission and reception between the ground station and the floating units. This unit supports multiple communication protocols and receives the floating units' location information, environmental data, and operating status in real time. It can also transmit control commands to the floating units and adjust their operation remotely. This unit is equipped with parallel processing capabilities to efficiently process data even when there are many floating units.

[0087] b. Data Analysis Module The data analysis module analyzes various data transmitted from the flotation device (temperature, atmospheric pressure, wind speed, location information, etc.) in real time, providing information necessary for controlling the device's operation and optimizing its route. This module utilizes a high-performance database and statistical algorithms to predict weather changes and air current trends. Furthermore, the analysis results are visualized, allowing operators to quickly grasp the situation.

[0088] c. AI control system The AI ​​control system makes decisions to optimize the altitude, position, and course of the floating aircraft. Based on real-time data from the floating aircraft, the system dynamically generates optimal control commands using machine learning algorithms. This AI also has the ability to predict future weather conditions and sudden environmental changes by linking with a weather database. It also manages the coordinated operation of the floating aircraft and assigns tasks to maximize overall efficiency. For example, if the AI ​​control system detects that a leading floating aircraft is currently experiencing stronger-than-usual winds or that the wind direction differs from weather data, it will exclude that route from the list of potential routes for subsequent floating aircraft.

[0089] d. User Interface (UI) System The user interface is intuitively designed to enable operation of the ground station. This includes a dashboard for real-time monitoring of the floating vehicle's status and a control panel for manually entering commands. The UI system is multilingual and allows for mode switching according to the operator's skill level.

[0090] e. Energy management module The energy management module monitors the floating spacecraft's energy usage and adjusts the operation of solar panels and batteries as needed. This module plays a role in directing energy efficiency optimization from the ground station, helping the floating spacecraft to operate stably over long periods.

[0091] f. Backup system The backup system has a function to ensure data security in case of a ground station failure. This involves regularly saving data to the cloud or other ground stations to enable rapid recovery.

[0092] The ground station, configured as described above, collects data from the floating vehicles in real time, and generates and transmits optimal control commands based on the analysis results. These commands are sent to the floating vehicles via a communication control unit, efficiently managing the vehicles' altitude adjustment, propulsion control, energy use, and other functions. Furthermore, the ground station's AI system comprehensively manages multiple floating vehicles, improving observation efficiency and operational accuracy through coordinated operation.

[0093] The ground station, with its flexible configuration and advanced analytical capabilities, plays a crucial role in supporting the safe and efficient operation of the floating aircraft. Therefore, it is designed to handle both single and multiple floating aircraft.

[0094] <Ground station hardware configuration> The ground station is equipped with the necessary hardware configuration to support the operation of the floating spacecraft. This configuration consists of various components for efficiently performing computation, data analysis, communication control, power management, and operational monitoring.

[0095] First, the core of the ground station is a high-performance computer server. This server is responsible for processing the vast amount of data transmitted from the floating spacecraft in real time and accurately generating operational commands. In particular, it is equipped with the latest multi-core processors and large-capacity memory to process diverse information such as weather data, sensor information, and floating spacecraft operation logs in parallel. This server also uses machine learning algorithms to analyze data and provides advanced predictive models to optimize the operation of the floating spacecraft.

[0096] Next, the communication control unit plays a crucial role. This unit manages bidirectional communication with the floating spacecraft, enabling accurate transmission and reception of data between the ground and the stratosphere. The communication control unit supports multiple communication protocols and is designed to quickly secure alternative routes in the event of communication failures by combining satellite communication, wireless communication, and fiber optic communication. Furthermore, high security is maintained through encryption technology for communication data.

[0097] The data storage system is also a core element of the ground station. This storage system stores data collected from the levitation vehicle long-term and records operational history and analysis results. By employing a hybrid configuration with SSDs that enable high-speed data access and conventional HDDs, it achieves efficient management of large amounts of data. This system also has a backup function, minimizing the risk of data loss.

[0098] Furthermore, the ground station has an integrated power supply system. This system is equipped with an uninterruptible power supply (UPS) and renewable energy generators, enabling stable operation over long periods. In particular, by utilizing solar and wind power, the system is designed to reduce environmental impact while ensuring uninterrupted energy supply even in emergencies.

[0099] The ground station also features an interface system designed to allow operators to intuitively understand the operational status of the flotation vehicle. This system has multiple high-resolution displays that visually show the vehicle's location, operational status, weather data, and more. It also employs a control panel with touch panel and voice input capabilities, allowing for rapid input of operational commands. The multilingual design enables flexible operation in international settings.

[0100] These hardware components work together to enhance the overall efficiency and reliability of the ground station. This configuration allows the ground station to function as the foundation for the precise and stable operation of the flotation vehicle.

[0101] The following describes the entire process flow for a floating vehicle, from initial setup on the ground to movement to the destination and final landing. 1. Initial setup and preparation for buoyancy The destination and optimal route for the floating vehicle can be pre-set at a ground station, but it is also possible to set the destination after it has taken off. This flexibility is made possible by the navigation control AI's ability to take in weather data and destination information in real time and respond to new instructions while floating. On the ground, the status of the buoyancy and propulsion systems is checked based on the latest weather data, and the helium supply system is activated to generate buoyancy.

[0102] 2. Ascent and Reaching the Stratosphere The buoyancy control system allows the flotation device to rise above the ground. The amount of helium gas injected is adjusted in real time by the navigation control AI to provide appropriate buoyancy. The propulsion system during ascent operates with minimal energy consumption and is intended for altitude adjustment. Upon reaching the stratosphere, it is ready to capture the jet stream.

[0103] 3. Capture and Utilization of Jet Stream Within the stratosphere, AI analyzes weather data in real time to select the optimal jet stream for reaching the destination. Altitude adjustments by the buoyancy control system and fine-tuning of the propulsion system work together to efficiently begin movement within the jet stream. Even if no destination is set, the floating device continues to move to an energy-efficient position using the jet stream.

[0104] 4. Long-distance travel During long-distance travel using the jet stream, the communication system maintains data exchange with ground stations, transmitting aircraft position and status information. The energy supply system generates electricity using solar panels during the day and stores surplus power in batteries. Stable operation is possible at night or on cloudy days by supplying power from the batteries.

[0105] 5. Circling and staying airborne using air currents When hovering or circling around a destination is required, the navigation control AI analyzes local airflow data and calculates a route suitable for hovering. This includes a method of continuously utilizing multiple surrounding air currents to circle the floating device near the destination. Specifically, altitude adjustment using a buoyancy control device and lateral position control using a propulsion system are combined to enable the floating device to maintain a stable orbit. This technology enables long-term operation in specific areas, such as for observation or communication relay.

[0106] 6. Route changes and air current transfers If weather conditions change during transit, the navigation control AI calculates a new route and identifies the next air current to switch to. At this time, the buoyancy control system and propulsion system work together to adjust altitude and position, allowing for a smooth transition to the next air current.

[0107] 7. Approaching the destination If a destination is set, the levitation device gradually descends as it approaches the destination. The AI ​​control system adjusts the amount of helium gas released (compressed and recovered) to reduce buoyancy and uses the propellers to calculate the optimal descent trajectory. If prolonged flight is required near the destination, another orbital route is planned.

[0108] 8. Final landing Once the flotation device reaches its destination, it releases more helium gas and descends safely. The propellers correct its position with minimal thrust and mitigate the impact of landing. A ground station performs final checks and the operation is terminated.

[0109] These processing flows enable the flotation device to offer configuration flexibility and long-term operation around its destination, resulting in precise and safe movement and hovering.

[0110] To ensure stable hovering even under harsh environmental conditions such as jet streams and turbulence when a floating aircraft orbits its destination, its altitude control, propulsion control, and trajectory planning must be meticulously coordinated. The floating aircraft, utilizing flight control AI, can provide a mechanism to effectively orbit its destination by leveraging multiple air currents.

[0111] Explanation of circling and staying in one place 1. Airflow data analysis and course planning The navigation control AI onboard the floating vehicle analyzes the characteristics of multiple air currents around the destination based on weather data and real-time observation information. It dynamically calculates a stable circular route, taking into account jet streams and localized turbulence. This calculation includes planning for efficient circling by utilizing air currents through altitude changes.

[0112] 2. Airflow switching by altitude adjustment To stay afloat in strong air currents, altitude adjustment using a buoyancy control device is key. The flotation device moves to stable air currents at specific altitude ranges, and the navigation control AI controls the injection and release of helium gas in real time. This altitude adjustment allows for efficient switching of air currents near the destination.

[0113] 3. Fine-tuning using the propulsion system In addition to altitude adjustment, the propulsion system (propeller) performs fine positional adjustments in the lateral and longitudinal directions. Even when the flotation device is significantly affected by strong air currents, it is designed to maintain its circular route through precise propulsion control using the propeller.

[0114] 4. Energy Management To minimize energy consumption during laps, the energy supply system is highly optimized. During the day, solar panels store electricity, and at night, batteries are used. In addition, the power of the propulsion system is controlled to the minimum necessary.

[0115] 5. Planning a loop-type circular route A loop-shaped route is planned that connects multiple air currents around the destination. Along this route, the flotation device will use one air current to move to one end of the destination, and then use the air current in the opposite direction to return, repeating the loop.

[0116] It is not necessary to establish a return route; other destinations may be planned one after another. Alternatively, the aircraft may land at a designated waiting area on the ground, recover the flotation device for maintenance and inspection, or transport it to another location and plan a route from that location.

[0117] <Details of each operation> <Floating motion> The levitation operation is as follows. Based on control signals from a ground station, the levitation device of the present invention levitates from the ground in the following procedure. By coordinating each component, the levitation device achieves highly accurate and efficient levitation.

[0118] 1. Generation of buoyancy The buoyancy control device is responsible for generating buoyancy. First, the helium supply system within the buoyancy control device activates, injecting an appropriate amount of helium gas from a high-pressure tank into the gas bag. Next, the pressure adjustment mechanism works in conjunction with real-time sensors to measure the external atmospheric pressure and optimize the internal pressure. The internal gas distribution piping evenly distributes the injected helium gas, ensuring uniform buoyancy throughout the entire gas bag. The reinforcing frame stabilizes the shape of the airbag and prevents over-inflation and deformation of the airbag during buoyancy generation. As described above, the flotation device obtains the basic buoyancy necessary to leave the ground.

[0119] 2. Auxiliary propulsion system The propulsion system assists with buoyancy. Once sufficient buoyancy is achieved and the float is ready to leave the ground, the propeller, driven by a brushless motor, begins to rotate. This propeller provides supplemental thrust in the vertical direction to the aircraft. The propeller mounting mechanism automatically adjusts the propeller angle and optimizes the direction of propulsion to match the direction of buoyancy. The motor drive circuit adjusts the propeller rotation speed in real time, controlling it so that the flotation device can obtain the precise thrust required. This allows the flotation device to utilize both buoyancy and thrust to begin a stable ascent. The propeller rotation speed is adjusted by a flight controller or similar device.

[0120] 3. Integrated operation of energy supply and control systems The energy supply system and navigation control AI work in coordination. During ascent, the energy supply system activates, providing a stable power supply from solar panels and batteries. Power supply from batteries is particularly important during the initial ascent, and it supplies power to the motors and control systems through a high-efficiency inverter circuit. The navigation control AI analyzes data from the sensor array and integrates the control of the buoyancy control system and the propulsion system. The sensor array collects weather data, wind speed, and barometric pressure information, and provides it to the navigation control AI.

[0121] This allows the flotation device to follow the optimal ascent path according to the environment.

[0122] 4. Transition to a stable upward trend The navigation control AI manages the stable ascent of the floating device. After the initial ascent, the navigation control AI makes the following adjustments to adapt to air currents and external conditions. The pressure adjustment mechanism adjusts the internal pressure in response to changes in external atmospheric pressure, maintaining appropriate buoyancy. The propulsion system performs fine thrust adjustments to maintain balance during ascent.

[0123] As a result, the flotation device continues to ascend while maintaining a stable posture.

[0124] 5. Reaching the stratosphere The flotation device continues to ascend until it reaches the target altitude. The navigation control AI continues to make the following adjustments: The pressure adjustment mechanism stabilizes buoyancy and maintains the target altitude. The propulsion system makes course changes and fine adjustments to position. This prepares the floating aircraft for operation at the target altitude.

[0125] 6. Stability control after surfacing Even after the floating device reaches its target altitude, the navigation control AI and various devices work together to maintain a stable floating state. The communication system works in real time with the ground station to transmit operational data. The navigation control AI adjusts each device according to weather conditions and air current fluctuations.

[0126] These actions allow the flotation device to efficiently and stably ascend from the ground and begin operations in the stratosphere.

[0127] <Movement using air currents> The air currents utilized by flotation devices at high altitudes are part of the Earth's atmospheric circulation and are a crucial element influencing global climate and weather. Air currents are primarily formed by the difference in heating between the Earth's surface and the atmosphere due to solar energy, the Earth's rotation, and topography. The combination of these factors creates complex wind patterns on Earth, which give rise to characteristic currents such as jet streams and local currents.

[0128] The jet stream is a particularly fast and stable flow of wind within the stratosphere, mainly located at an altitude of around 10-15 km. These streams form belt-shaped currents known as the polar easterlies and subtropical easterlies in the Northern and Southern Hemispheres, respectively, and play a role in global atmospheric circulation. Furthermore, the intensity and location of these streams change depending on the season and weather conditions, and consequently, they also affect the climate at the Earth's surface.

[0129] By efficiently utilizing the jet stream, the floating aircraft enables long-distance travel while minimizing propulsion energy consumption. For example, when traveling from Tokyo to Los Angeles, it can capture the eastward jet stream at an altitude of 10-15 km and cross the Pacific Ocean. By utilizing the jet stream in this way, travel time can be reduced and energy efficiency improved.

[0130] Localized air currents are stable wind flows that form in specific terrains or regions, and are used for lingering near destinations and for fine-tuning one's position. For example, when traveling from Tokyo to Nagano, relatively stable localized air currents are used to optimize short-distance travel.

[0131] These air currents can be likened to a transportation network where you can reach your destination by changing trains or buses. The floating vehicle analyzes the air current conditions in real time through its navigation control AI and selects the optimal route. First, it adjusts its altitude to ride the target air current, and uses that flow to move to the next point. Then, it changes to another air current to approach its destination. By repeatedly changing air currents in this way, it becomes possible to reach any point on Earth with minimal energy.

[0132] The navigation control AI possesses the ability to flexibly respond to air currents, enabling it to cope with sudden weather changes and turbulence. This opens up possibilities for a new mode of transportation that utilizes a global air current network.

[0133] The levitation device of this embodiment is a technology that utilizes tropospheric and stratospheric air currents to achieve movement to and stay at a destination. By utilizing jet streams and localized stable air currents and adjusting altitude and course in real time, efficient and accurate movement is possible over both short and long distances. I will explain using travel methods from Tokyo to Nagano, Osaka to Fukuoka, and Tokyo to Los Angeles as examples.

[0134] <Example: Travel from Tokyo to Nagano> The distance between Tokyo and Nagano is relatively short, about 180 km, making it suitable for travel within the troposphere near the ground, without requiring an ascent to the stratosphere. Starting point (Tokyo): Latitude 35.6895°N, Longitude 139.6917°E, Altitude 100 m The aircraft ascended to an altitude of 500 m using buoyancy control devices. The propellers were stopped to conserve energy. Riding on a local wind (northwesterly wind, speed: 15 km / h, direction: northwest), we are heading towards Nagano. Midpoint (near Gunma Prefecture): Latitude 36.3907°N, Longitude 139.0622°E, Altitude 700 m As we approached mountainous terrain, we activated the propellers. We made fine adjustments to the float's course to catch the valley breeze, and used the breeze (speed: 10 km / h, direction: north) to adjust the altitude to 900 m. Destination (Nagano): Latitude 36.6513°N, Longitude 138.1810°E, Altitude 500 m The buoyancy control system was controlled to gradually lower altitude, and the aircraft landed while maintaining stable flight using the mountain breeze near Nagano City (speed: 12 km / h, direction: southwest). Duration: 2-3 hours

[0135] <Example: Traveling from Osaka to Fukuoka> The distance between Osaka and Fukuoka is approximately 600 km, which is a moderate distance. Therefore, travel within the troposphere (altitude 1,000-2,000 m) is appropriate, without ascending to the stratosphere. Starting point (Osaka): Latitude 34.6937°N, Longitude 135.5023°E, Altitude 100 m The aircraft ascends to an altitude of 1,000 m using buoyancy control devices. It then uses its propellers to catch the westerlies (speed: 30 km / h, direction: west). Midpoint (near Hiroshima): Latitude 34.3853°N, Longitude 132.4553°E, Altitude 1,200 m Over the Seto Inland Sea, as the westerlies weakened, the aircraft adjusted its altitude to 1,500 m using buoyancy control devices and propellers, moving to a position where it could catch the westerlies. It then switched to a new westerly wind (speed: 20 km / h, direction: west-northwest). Destination (Fukuoka): Latitude 33.5902°N, Longitude 130.4017°E, Altitude 800 m The propellers were stopped, and the aircraft used the local wind near Fukuoka (speed: 15 km / h, direction: south-southwest) to reach the vicinity of its destination. Finally, the propellers were used for fine adjustments before landing at the destination. Duration: 4-5 hours

[0136] <Example: Travel from Tokyo to Los Angeles> • Starting point (Tokyo) The aircraft departs from Tokyo (latitude 35.6895°N, longitude 139.6917°E, altitude 100 m) and ascends to an altitude of 12,000 m using buoyancy control devices. After ascending, it rides the high-altitude jet stream (speed: 300-400 km / h, direction: east-west) and begins moving across the Pacific Ocean towards Los Angeles. The propellers are stopped except when adjusting altitude, and the aircraft moves depending on the speed and direction of the airflow. However, the propellers may be controlled to tilt the aircraft relative to the airflow in order to stabilize the aircraft and effectively utilize dynamic lift. • Midpoint (on the Pacific Ocean) Near the midpoint in the Pacific Ocean (latitude 35.0°N, longitude 180.0°W, altitude 12,500 m), if the direction or speed of the jet stream changes, the navigation control AI analyzes weather data and selects a new airflow. At points where the jet stream weakens, the buoyancy control system and propellers are used to adjust the altitude to 13,000 m before switching to the next airflow. If weather conditions are stable, the aircraft will continue to travel at an average speed of approximately 350 km / h by utilizing the jet stream. • Destination (Los Angeles) Upon reaching the vicinity of Los Angeles (latitude 34.0522°N, longitude 118.2437°W, altitude 1,000 m), the buoyancy control system and propellers are activated to gradually lower altitude. Simultaneously, local winds near the ground (speed: 20-30 km / h, direction: west) are used to maintain stable flight around the destination. Finally, fine adjustments are made using the propellers to ensure a safe landing. • Duration The travel time from Tokyo to Los Angeles depends on the speed and direction of the jet stream, but under normal weather conditions, it takes approximately 30 to 36 hours. This time can vary depending on adjustments and altitude changes at jet stream transition points, and the frequency of propeller use.

[0137] <Staying motion of the levitation device> To achieve stable hovering around its destination in the troposphere and stratosphere, the floating aircraft's flight control AI primarily adjusts its altitude and position. The hovering operation utilizes regional airflow characteristics, enabling efficient and precise operation. Several examples illustrate this. 1. Staying in the airspace above London Over London, the aircraft will utilize the stratospheric jet stream and localized stable air currents. The flight control AI analyzes the westward jet stream located at an altitude of 10-15 km and the eastward localized air currents around 20 km, and designs a loop-shaped circumferential route that combines these. The flight control AI analyzes weather data in real time and instructs the buoyancy control device to adjust altitude. If turbulence occurs, the flight control AI activates the propulsion system and fine-tunes the position of the flotation device to prevent deviation from the route. This allows the floating aircraft to remain above London with efficient energy consumption.

[0138] <Example: Staying over Tokyo> Over Tokyo, the unique jet stream of East Asia is utilized. Since the jet stream at an altitude of 10-15 km flows from west to east, it can be used for travel from the west side of the destination. By using the stable local air currents at an altitude of 20-25 km, long-term dwell near the destination is possible. The flight control AI optimizes the circling route around the destination based on airflow data from sensors. The flight control AI also controls the propulsion system, making fine positional adjustments near the destination. This allows the levitation device to maintain a stable position over Tokyo while maximizing energy efficiency.

[0139] <Example: Staying in the airspace above Antarctica> In the skies above Antarctica, it is possible to linger by utilizing the polar vortex and polar circulation currents. The polar vortex at an altitude of 20-30 km is suitable for the flotation device to form a natural circular route. The flight control AI analyzes the movement of the polar vortex and operates the buoyancy control device to keep the flotation device within the polar vortex. If necessary, the flight control AI uses the polar circulation currents to perform localized movements. This will enable the floating device to conduct long-term observations and relay communications in specific areas of Antarctica.

[0140] The above describes the actions of lifting off the ground, moving to the destination, and staying in place.

[0141] Next, we will describe some variations and application examples.

[0142] A system in which multiple floating devices cooperate to share and utilize information enables wide-area observation, efficient operation, and advanced control that would be impossible with a single floating device. This system is based on real-time data exchange and integrated decision-making by AI, and its design integrates information collection, integrated analysis, autonomous control, and cooperative operation. First, as a foundational structure for information sharing, a robust communication network is necessary for multiple floating vehicles to share information. This network employs a mesh network system, allowing each floating vehicle to communicate directly with the others, thus enabling information sharing without going through ground stations or satellites. This ensures that even in the event of a communication failure, the flow of information can be maintained by utilizing alternative routes.

[0143] Furthermore, a platform has been built to comprehensively analyze the data collected by each floating device. This allows for the real-time integration of data from different perspectives, enabling a highly accurate overall understanding of the environment and situation. This platform is dynamically optimized by AI, automatically adjusting the observation range and mission to minimize energy consumption while improving accuracy.

[0144] The data collected by sensors from multiple floating units covers a wide range of parameters, including temperature, wind speed, humidity, and atmospheric pressure, and this data is shared through a mesh network. This shared data is analyzed by ground stations and cloud-based AI to predict environmental conditions and airflow changes in real time. Based on these analysis results, each floating unit is instructed on new routes and tasks. Furthermore, if some floating units encounter problems, nearby units will take over functions to ensure the continuation of data collection and communication.

[0145] One application of this system is wide-area weather observation. By having multiple floating devices work together, it is possible to collect weather data over a wide area in the stratosphere in real time, enabling early detection of localized weather phenomena. This allows for high-precision tracking of typhoon and jet stream movements, contributing to disaster prediction and damage mitigation.

[0146] Furthermore, its use as a communication platform is also anticipated. In times of disaster or in areas with inadequate communication infrastructure, the floating devices can function as part of a network, providing a stable communication environment over a wide area. In addition, it can be useful for environmental monitoring, enabling wide-area and high-precision monitoring of air pollution and greenhouse gas distribution. This will allow for the integration of observation data from different altitudes and regions, supporting the visualization of environmental problems and the formulation of countermeasures.

[0147] Such systems present technical challenges, including communication stability, energy management, and the advancement of AI. However, these challenges can be adequately addressed by strengthening mesh networks, improving the efficiency of solar charging, and introducing AI technology that enables individual floating units to make autonomous decisions. This system, in which multiple floating units share information and operate in coordination, is a key factor in maximizing the capabilities of each unit while simultaneously improving overall efficiency and reliability.

[0148] <Cargo handling actions> The flotation device of this embodiment is designed to achieve safe and precise transport by utilizing advanced control functions and efficient energy management functions in cargo handling. Cargo handling operations include loading cargo, transporting it to its destination, lowering and handing over the cargo, and returning to the port.

[0149] First, the floating aircraft receives cargo at a loading platform located at a ground station or relay station. This platform is equipped with a crane or automatic lifting mechanism for safely and efficiently loading cargo, which is then stored in the floating aircraft's cargo space. The cargo space consists of lightweight, high-strength carbon fiber containers, allowing for flexible storage according to the shape and size of the cargo. During cargo loading, loading sensors mounted on the floating aircraft measure the weight and center of gravity of the cargo in real time and transmit this information to the flight control AI. Based on this information, the flight control AI adjusts the buoyancy control system and propulsion system, and performs control to enable stable flight even with a loaded cargo.

[0150] After loading the cargo is complete, the floating aircraft sets the optimal flight route using a ground station or its onboard flight control AI. This flight route is calculated based on weather data, air current information, and the location of geographical obstacles, and it minimizes energy consumption while transporting the cargo to its destination by efficiently utilizing jet streams and local currents. In particular, for long-distance transport, it is possible to maximize transport efficiency by utilizing stable air currents in the stratosphere.

[0151] Based on instructions from the flight control AI, the flotation device activates its buoyancy and propulsion systems to begin ascent and cruise towards its designated destination. During this cruising flight, the buoyancy system adjusts its internal pressure in real time in response to changes in cargo weight and external environmental fluctuations to maintain a stable altitude. The propulsion system drives highly efficient propellers to control direction and fine-tune position toward the destination. Furthermore, the flotation device's energy supply system utilizes solar panels and batteries to stably supply the power necessary for the propulsion and communication systems. In cloudy weather or at night, an auxiliary fuel cell is activated to prevent interruptions in the energy supply.

[0152] When the levitation device reaches its destination, the flight control AI instructs it to begin the cargo descent. At this time, the levitation device lowers the cargo to the ground using a reel-type cable or an automatic descent mechanism. During this descent, the flight control AI monitors wind speed and the surrounding environment in real time and adjusts the position of the levitation device as needed to ensure the cargo is lowered safely and accurately. In addition, an authentication system using QR codes (registered trademark) or RFID tags is activated when the cargo is handed over, providing a function to prevent misdelivery and loss.

[0153] Once the cargo has been delivered, the floating vehicle, based on instructions from the flight control AI, will either return to the ground station or begin its journey to its next destination. During this process, the flight control AI optimizes the return route and efficiently utilizes air currents to minimize energy consumption. The battery is recharged during the return journey to prepare for the next operation.

[0154] Furthermore, the cargo transport operations of the floating aircraft incorporate safety measures for emergencies. For example, in the event of a communication failure, the autonomous navigation function on board the floating aircraft will activate and continue moving to a pre-set safety point. Also, if extreme weather is predicted, the flight control AI will quickly change altitude and route to ensure safety. As a result, the floating aircraft minimizes risks during cargo transport and operates as a highly reliable transport system.

[0155] Through the above operations, the flotation device of the present invention can safely and efficiently transport cargo, and as a technology that contributes to improved logistics efficiency and reduced environmental impact, it can be applied to a variety of operational scenarios. Note that cargo includes living organisms. It may also transport people.

[0156] <Measures to avoid problems> The floating device of this embodiment is designed for long-term, stable operation, primarily in the stratosphere. However, its operation presents technical challenges. This chapter will describe in more detail the main challenges that may arise and their solutions. 1. Challenges and Solutions in Energy Supply assignment Because the floating aircraft will remain airborne for extended periods, a stable energy supply is required day and night. However, solar panels cannot generate electricity during cloudy weather or at night, and energy shortages could lead to operational interruptions. solution The floating device will be equipped with highly efficient solar panels to charge its batteries using daytime sunlight. Lightweight and highly efficient solar panels, such as perovskite or organic thin-film types, will be used to minimize the overall weight of the floating device. Additionally, wind power generation using propellers or vibration power generation utilizing wind-generated vibrations may be employed during levitation. Furthermore, the following specific solutions will be implemented. i) Introduction of a power management system The power management system prioritizes key functions such as propulsion systems and communication systems, efficiently distributing energy. This system uses AI control to monitor energy usage in real time and, if necessary, shuts down some functions or switches to low-power mode. ii) Adoption of auxiliary energy supply devices To prepare for cloudy days and nighttime conditions, we will consider using lightweight fuel cells and radioisotope batteries (RTGs). Fuel cells have high energy density and can supply sufficient power even at night. Furthermore, these auxiliary devices will be designed to activate automatically if solar panel power generation is insufficient.

[0157] Furthermore, while on standby on the ground, the system will utilize solar panels and ground-based auxiliary power sources to store energy, thereby increasing efficiency when it restarts. By combining these mechanisms, the floating device can ensure a stable energy supply 24 hours a day.

[0158] 2. Loss of buoyancy due to rupture of the air sac. assignment If the airbags that provide buoyancy to the flotation device are damaged, buoyancy will be lost, creating a risk of crashing to the ground. solution The air sac is designed as follows to minimize the risk in case of rupture. i) Adoption of a compartment structure The airbag is divided into multiple independent compartments, so that even if one compartment is damaged, the other parts maintain buoyancy. This structure makes it possible to localize the loss of buoyancy caused by damage. ii) Installation of damage detection sensors The air sac is equipped with a highly sensitive damage detection sensor that can immediately detect even minor damage. This sensor identifies the location of the damage and sends a signal to the automated repair system. iii) Automatic repair mechanism The air sac incorporates an automatic repair mechanism that rapidly releases repair material to damaged areas. This repair material, containing special resins and shape-memory polymers, instantly seals the damaged area. iv) Internalization of auxiliary air sacs A small auxiliary gas sac is positioned inside the main gas sac to provide additional buoyancy. This auxiliary gas sac automatically deploys if the main gas sac is severely damaged, temporarily ensuring the stability of the flotation device. v) Fall prevention measures As a solution to the risk of a crash to the ground due to loss of control, Features include an automatically deploying parachute for safe descent in emergencies, a lightweight design to minimize impact, and the selection of safe zones to avoid human casualties during communication disruptions. These aspects are handled by an autonomous navigation AI.

[0159] These features minimize the risk of gas bag rupture, significantly improving safety for the flotation device.

[0160] 3. Interruption of operations due to communication failures assignment If the levitation vehicle loses communication with the ground station, it may become uncontrollable and the mission could be interrupted. solution The following design features will be implemented to prepare for communication failures. i) Implementation of autonomous navigation function The floating aircraft is equipped with AI that allows it to continue operating autonomously even if communication is lost. This AI selects pre-set routes and safe areas to remain in operation. ii) Multiplexing of communication methods Multiple communication methods, such as satellite communication, wireless communication, and optical communication, are used in parallel. This allows other methods to function as backups if one communication method fails. iii) Data logging function To prevent the loss of critical data when communications are restored, a high-capacity data logging system will be installed inside the floating spacecraft. This system will retain all data collected during the communication outage and transfer it to the ground station after the communication is restored. iv) Ensure communication stability by choosing ground standby or altitude change during extreme weather conditions where communication failures are likely to occur. These mechanisms allow the floating aircraft to continue operating safely even if a communication failure occurs.

[0161] 4. Mission failure due to unexpected weather conditions assignment Extreme weather conditions (such as typhoons, extreme cold, or extreme heat) may make it difficult to operate the floating aircraft. solution i) Strengthening weather analysis with AI The AI ​​mounted on the floating vehicle has the ability to analyze weather satellite data and ground observation data in real time and detect extreme weather conditions early. Based on the results of this analysis, it will issue instructions to evacuate to a safe area. ii) Adoption of weather-resistant materials The outer shell of the levitation device uses weather-resistant material that can withstand extreme temperature changes and rainfall. This material is UV resistant and waterproof, maintaining its performance even under harsh conditions for extended periods. iii) Avoidance by changing altitude Based on AI instructions, the flotation device significantly alters its altitude to avoid dangerous weather conditions. This feature makes it possible to avoid low-altitude weather conditions such as typhoons. iv) Ensuring safety by remaining on the ground In the event of extreme weather conditions such as typhoons, the floating vehicle can descend to a safe ground station and wait until weather conditions stabilize. During this waiting period, it is designed to maintain energy supply and communication functions, enabling rapid restart. Furthermore, if communication with the ground station or other floating vehicles is lost due to a malfunction, or if there is trouble with the propulsion system, the autonomous navigation AI will wait at a nearby ground station or on the ground and emit an emergency signal. v) Combination of altitude change and ground standby Depending on the size and path of the typhoon, the floating device can choose to either increase its altitude to move to the stratosphere, where it will be unaffected by the typhoon, or descend to the ground and wait. This allows for flexible responses depending on the situation.

[0162] These measures increase the flotation vehicle's resilience to extreme weather conditions and improve the mission's success rate.

[0163] 5. Damage caused by crashing to the ground assignment If the floating aircraft loses control and crashes to the ground, there is a risk of causing human and property damage. solution i) Automatic deployment parachute system The floating device is equipped with a parachute system that automatically deploys in emergencies. When the AI ​​detects an anomaly, this parachute activates immediately, allowing for a safe descent. ii) Lightweight design The floating device's structure utilizes lightweight materials and incorporates features to minimize impact on the ground. This reduces damage in the event of a crash. iii) Selection of ground safety zones When communication is lost, the AI ​​selects a pre-configured safe zone on the ground and descends. This zone has conditions set to avoid human casualties.

[0164] These designs allow the floating aircraft to minimize damage even in the worst-case scenario.

[0165] Thus, the flotation device of this embodiment can implement solutions to challenges such as energy supply, loss of buoyancy, communication failures, extreme weather, and crash risk by utilizing AI technology and redundant design. As a result, the flotation device control system becomes a technology that can be effectively operated in a variety of applications as a system with safety and reliability. [Explanation of symbols]
