Description

Technical Field

[0001] This invention relates to the field of aircraft technology, and in particular to a hybrid multi-functional airship that integrates all-weather adaptability and intelligent safety redundancy. Background Technology

[0002] As an aircraft that relies on buoyancy provided by buoyant gas, airships have broad application prospects in many fields such as logistics transportation, aerial photography, emergency rescue, environmental monitoring and communication relay due to their unique advantages such as low-altitude and low-speed flight, long endurance and large-payload transportation. They have become one of the important research directions in the field of aircraft technology. However, traditional airships and hybrid airships are extremely sensitive to weather conditions and their operational range is limited to ideal weather with clear skies and light winds. In strong winds, airships lack effective active wind resistance mechanisms and are prone to problems such as attitude loss and flight path deviation. In thunderstorms, the airship's large size makes it a high-risk target for lightning strikes. Sudden events such as hail and bird strikes can easily cause the airship's skin to rupture and gasbags to leak, directly threatening flight safety. The low temperature environment at high altitudes can cause ice to form on the airship's surface and rotor blades, damaging its aerodynamic shape, increasing flight weight, and even causing fatal risks such as rotor stall.

[0017] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 4As shown, this embodiment provides a hybrid multi-functional airship integrating all-weather adaptability and intelligent safety redundancy. It includes a buoyancy body 1, filled with buoyancy gas. A pod 2 is installed at the bottom of the buoyancy body 1. Two main propulsion mechanisms 3 are symmetrically installed on the surface of the buoyancy body 1. Four auxiliary propulsion mechanisms 4 are installed on the surface of the buoyancy body 1. An intelligent energy management mechanism 5 and a central flight control unit 6 are installed inside the pod 2. The central flight control unit 6 is used to dynamically control the main propulsion mechanisms 3 and auxiliary propulsion mechanisms 4. A multi-airbag safety redundancy mechanism 8 is installed inside the buoyancy body 1. A helium recovery and storage mechanism 9 is installed inside the pod 2. An autonomous obstacle avoidance mechanism 10 and an all-weather adaptability mechanism 11 are installed on the surface of the buoyancy body 1. The autonomous obstacle avoidance mechanism 10 and the all-weather adaptability mechanism 11 enable the airship to operate safely under various harsh weather conditions. The main propulsion mechanism 3 includes an integrally tilting rotor unit, and the auxiliary propulsion mechanism 4 is a ducted fan with independent attitude control. Through the coordinated operation of these mechanisms, vertical takeoff and landing, efficient cruise, and precise hovering are organically unified, meeting the needs of multi-scenario operations.

[0018] Furthermore: In an optional embodiment, the surface of the buoyancy body 1 is provided with a skin 12, which is a multi-layer composite structure. The multi-layer composite structure consists of a temperature control layer, an anti-icing layer, an impact protection layer, an airtight layer, and an airbag liner layer from the outside to the inside. The outermost sun-protective temperature control layer is a high solar reflectivity coating. The next outermost antifreeze and anti-icing layer includes an electrically heated film or a gas-thermal anti-icing system laid on the buoyancy body 1 and the leading edge of the rotor blades. It is powered by an intelligent energy management mechanism 5 and is used to prevent or remove ice under icing conditions. The middle impact protection layer is a high molecular weight polyethylene fiber layer to resist hail or bird strikes. The inner airtight layer is a low gas permeability film. The innermost airbag liner layer is a flexible material compatible with the buoyancy gas. The multi-layer structure performs its own function and works together to protect the buoyancy body 1, ensuring the structural integrity of the buoyancy body 1 and achieving multi-dimensional environmental adaptability protection.

[0019] Furthermore: In an optional embodiment, the all-weather adaptability mechanism 11 includes a windproof module 111, which consists of a central flight control unit 6, an active propulsion mechanism 3, and an auxiliary power mechanism 4. By sensing wind speed and direction through sensors, it automatically adjusts the thrust magnitude and direction of the rotor and ducted fan to counteract the wind force. It does not need to passively avoid strong winds and can actively resist wind forces of different directions and intensities, ensuring the stability of the airship's position and attitude in complex wind field environments.

[0020] Furthermore: In an optional embodiment, a lightning protection module 112 is fixedly connected to the surface of the skin 12, and a discharge brush fixedly connected to the surface of the pod 2 extends to the end of the buoyancy body 1 to safely guide lightning charges into the atmosphere. The lightning protection module 112 is connected to the discharge brush via wires to form a complete lightning protection circuit, which prevents lightning charges from damaging the electronic equipment and structure inside the airship and ensures flight safety in thunderstorms.

[0021] Furthermore: In an optional embodiment, the surfaces of the buoyancy body 1, the main power mechanism 3, and the auxiliary power mechanism 4 are respectively provided with anti-icing modules 114 for removing ice layers under icing conditions. The anti-icing modules 114 are powered by the intelligent energy management mechanism 5. The buoyancy body 1 is equipped with a temperature sensor and a temperature regulation system to maintain the gas temperature inside the airbag within a preset range. This can prevent ice layers from affecting aerodynamic performance and flight safety, and also avoid buoyancy loss of control caused by abnormal gas temperature, ensuring stable operation in low-temperature environments.

[0022] Furthermore: In an optional embodiment, the autonomous obstacle avoidance mechanism 10 includes an all-weather perception module 102. The sensors of the all-weather perception module 102 include a millimeter-wave radar and an infrared thermal imaging camera that are unaffected by weather. The infrared thermal imaging camera of the all-weather perception module 102 is installed on both sides of the pod 2. It can still accurately detect obstacles under low visibility conditions such as heavy fog, rain, and snow, providing reliable environmental perception support for the airship's flight.

[0023] Furthermore: In an optional embodiment, the multi-airbag safety redundancy mechanism 8 includes a main airbag 81 and a secondary airbag 82, which can automatically isolate the leak in the event of a leak in any airbag and compensate for the loss of buoyancy through the power system, effectively avoiding the airship's instability and crash caused by a single airbag leak, and greatly improving the airship's survivability and safety redundancy level in extreme situations.

[0024] Furthermore: In an optional embodiment, the helium recovery and storage mechanism 9 includes a compressor unit 92, a condensation and liquefaction device 93, and a cryogenic Dewar flask 94, for recovering and liquefying helium leaked or discharged from the airbag, thereby realizing the recycling of helium, reducing helium consumption costs, and improving the economy and sustainability of airship operation.

[0025] Furthermore: In an optional embodiment, the autonomous obstacle avoidance mechanism 10 also includes a lidar and a vision camera, used to generate a collision-free path through a path planning module integrated in the central flight control unit 6. The multi-sensor fusion perception of the environment, combined with real-time path planning, enables autonomous obstacle avoidance in complex environments, thereby improving the intelligence and autonomy of the airship's flight.

[0026] Furthermore: In an optional embodiment, the bottom surface of the pod 2 is provided with a tethered and autonomous flight switching mechanism 7. The tethered and autonomous flight switching mechanism 7 includes a tethered interface mechanism, a cable retraction mechanism and a mode switching controller installed at the bottom of the pod 2, which allows the airship to seamlessly switch between tethered hovering and autonomous flight modes, and can flexibly adapt to fixed-point operation and mobile operation scenarios, thereby improving the airship's mission adaptability and usage flexibility.

[0027] Working principle: Through the unified scheduling of the central flight control unit 6, the main propulsion mechanism 3, auxiliary power mechanism 4, intelligent energy management mechanism 5, multi-airbag safety redundancy mechanism 8, helium recovery and storage mechanism 9, autonomous obstacle avoidance mechanism 10 and all-weather adaptation mechanism 11 are linked to achieve closed-loop coordination of power control, environmental adaptation, safety protection and energy optimization, so as to ensure that the airship can complete its mission safely, stably and efficiently under various harsh weather conditions. The rotor unit of the main power mechanism 3 can be tilted as a whole. When the rotor unit is arranged horizontally, it provides the main propulsion for horizontal cruising of the airship. When the rotor unit is arranged vertically, it works with the ducted fans of the four auxiliary power mechanisms 4 to provide lift for vertical take-off and landing and precise hovering. The central flight control unit 6 receives real-time data from airship attitude sensors such as gyroscopes and accelerometers, and dynamically adjusts the rotor speed and tilt angle of each main power mechanism 3, as well as the ducted fan speed and exhaust direction of each auxiliary power mechanism 4, to achieve precise control of the airship's pitch, roll, yaw and other attitudes, and meet various flight requirements such as vertical take-off and landing, efficient cruise, and hovering. The autonomous flight switching mechanism 7 on the bottom of the pod 2 fixes the tether cable through the tether interface mechanism. The cable retraction mechanism adjusts the cable length according to flight requirements. The mode switching controller locks the power output logic of the main power mechanism 3 and the auxiliary power mechanism 4, retaining only the attitude fine-tuning function, so that the airship can hover stably at the specified altitude. The mode switching controller receives instructions from the central flight control unit 6, controls the cable retraction mechanism to retract the mooring cable, unlocks the full tilt function of the main power mechanism 3 and the full attitude control authority of the auxiliary power mechanism 4, and the airship autonomously plans the flight path by the central flight control unit 6 according to the preset route or real-time environmental data. The wind speed and direction sensors are integrated into the sensor group of the autonomous obstacle avoidance mechanism 10 to collect environmental wind speed and direction data in real time and transmit them to the central flight control unit 6. The central flight control unit 6 calculates the force of the wind on the airship, including the magnitude of the thrust and the direction of the offset, and sends reverse thrust commands to the main power mechanism 3 and the auxiliary power mechanism 4 to adjust the rotor speed and the airflow intensity and direction of the ducted fan to form a resultant force that cancels out the wind force, so that the airship can maintain its position and attitude stability in strong wind environment and achieve active wind resistance rather than passive avoidance. The lightning protection module 112 fixed on the surface skin 12 of the buoyancy body 1 has a conductive lightning protection strip extending longitudinally along the buoyancy body as a lightning receiver. Its material is a highly conductive metal such as copper alloy, which can actively attract lightning charges. The lightning charges are conducted through wires to the discharge brush fixed on the surface of the pod 2. The discharge brush extends to the tail of the airship and uses the tail airflow to accelerate the release of charges, safely guiding the lightning charges into the atmosphere. At the same time, the metal structure of the pod 2 acts as an equipotential body to balance the potential of various parts of the airship, preventing the charges from breaking down the internal electronic equipment and achieving active lightning protection. The skin 12 of the buoyancy body 1 adopts a five-layer composite structure. The middle layer, the impact-resistant layer, is made of ultra-high molecular weight polyethylene fiber. This material has extremely high tensile strength and impact toughness. When encountering hail, bird strikes, or falling objects, the impact-resistant layer absorbs the impact energy through its own toughness, preventing the impact force from being transmitted to the inner airtight layer and the airbag liner, thus preventing the main airbag 81 or the auxiliary airbag 82 from rupturing. At the same time, the outer temperature control layer and anti-icing layer can help disperse the impact force and improve the overall impact resistance of the skin. Temperature sensors are installed inside the buoyancy body 1, on the leading edge of the rotor blades of the main propulsion mechanism 3, and in the ducted air intake of the auxiliary propulsion mechanism 4. The surface temperature of the leading edge of the fan blade is monitored in real time. When the temperature is detected to be lower than the icing threshold, a power supply request is sent to the intelligent energy management unit 5. The intelligent energy management unit 5 supplies power to the electric heating film of the outermost layer of the skin 12. The electric heating film generates heat through the Joule effect, which directly heats the leading edge of the blade and the windward surface of the buoyancy body to prevent ice formation. If ice has already formed, the power supply can be increased to quickly melt the ice and avoid the ice from damaging the aerodynamic shape, increasing the flight weight, or causing the rotor to stall. The outermost sun protection and temperature control layer of the skin 12 is a white or silver coating with high solar reflectivity, which can reflect solar radiation heat and reduce the expansion caused by helium absorbing heat. Temperature and pressure sensors inside the buoyancy body 1 monitor the temperature and pressure of helium in the main airbag 81 and auxiliary airbag 82 in real time. When the temperature exceeds the preset range of 25℃-35℃, the central flight control unit 6 activates two control methods: first, it controls the gas circulation system to accelerate the heat exchange between the helium inside the airbag and the external environment; second, it sends a command to the helium recovery and storage mechanism 9 to extract a small amount of helium into the storage system to reduce the pressure inside the airbag and prevent the helium from overheating and expanding, which could lead to loss of buoyancy control. The all-weather perception module 102 of the autonomous obstacle avoidance mechanism 10 uses multiple sensors. The fusion strategy enables the millimeter-wave radar, with a detection range of several kilometers, and infrared thermal imaging cameras, mounted on both sides of the pod 2, to initiate primary detection when the detection accuracy of visual cameras and lidar decreases in low-visibility environments such as heavy fog, rain, and snow. The millimeter-wave radar can accurately identify large fixed obstacles such as mountains and buildings, while the infrared thermal imaging cameras can capture moving obstacles such as other aircraft and heat sources. The detection data is transmitted in real time to the path planning module of the central flight control unit 6, which quickly generates a collision-free correction path to ensure that the airship can be seen and fly stably under low-visibility conditions. The multi-airbag safety redundancy mechanism 8 inside the buoyancy body 1 includes a main airbag 81 and two isolated auxiliary airbags 82. Independent electromagnetic isolation valves are set between the main airbag and the auxiliary airbags. Pressure sensors are installed inside each airbag. When any airbag leaks, the pressure sensor of the corresponding airbag detects a rapid drop in pressure and immediately sends a leak signal to the central flight control unit 6. The central flight control unit 6 controls the electromagnetic isolation valve of the leaking airbag to close, preventing the buoyancy gas in other airbags from leaking. At the same time, the main power mechanism 3 and the auxiliary power mechanism 4 are activated to increase the thrust to compensate for the buoyancy loss caused by the leak, ensuring the stability of the airship's attitude and avoiding instability and crash. Excess helium extracted during temperature control module regulation, helium discharged during airbag maintenance or replacement, and the helium that needs to be discharged after the multi-airbag safety redundancy mechanism 8 isolates leaking airbags are used to balance buoyancy. The central flight control unit 6 controls the opening of the helium pipeline valve, and the helium first enters the compressor unit 92 and is compressed to a high-pressure state. Then it enters the condensation and liquefaction device 93, where the high-pressure helium is liquefied through cryogenic refrigeration technology. Finally, the liquid helium is stored in the cryogenic Dewar flask 94. When it is necessary to replenish the helium in the airbag, such as for leakage compensation or attitude adjustment, the central flight control unit 6 controls the opening of the Dewar flask valve, and the liquid helium is converted into gaseous state through the vaporization device and then returned to the designated airbag through the pipeline, realizing the closed-loop recycling and reuse of helium and reducing operating costs. The intelligent energy management unit 5 is installed inside the pod 2, integrating energy storage units such as lithium battery packs, fuel cells, power distribution modules, and energy consumption monitoring modules. It supplies power to all electrical modules, including the central flight control unit 6, the main propulsion mechanism 3, the auxiliary power mechanism 4, the all-weather adaptation mechanism 11, and the autonomous obstacle avoidance mechanism 10. The energy consumption monitoring module collects energy consumption data from each module in real time. The power distribution module dynamically allocates power according to the instructions of the central flight control unit 6, prioritizing the power supply to the central flight control unit 6 and the autonomous obstacle avoidance mechanism 10. In severe weather, it increases the power supply quota of the all-weather adaptation mechanism 11, such as the anti-icing module and the lightning protection module. In cruise mode, it optimizes the power supply efficiency of the propulsion mechanism and reduces energy consumption. When the energy storage unit's power is insufficient, it can activate backup energy sources such as solar panels. If a return-to-base command is configured or triggered, it ensures a stable energy supply. The autonomous obstacle avoidance mechanism 10, with its lidar, millimeter-wave radar, visual camera, and infrared thermal imaging camera, uses an all-weather perception module 10 to collect flight environment data from 2360° without blind spots. This data includes the location, size, speed, and distance of obstacles. The data is transmitted to the path planning module integrated in the central flight control unit 6. The module uses a set algorithm or a fast random tree search algorithm, combined with parameters such as the airship's flight speed, attitude limitations, and power performance, to generate a collision-free optimal flight path in real time. It then sends attitude adjustment commands to the power mechanism to achieve autonomous obstacle avoidance without human intervention.
