[0002] CONSTRUCTION ARRANGEMENT FOR AERIAL ELECTRIC VEHICLE PLATFORM

[0003] Innovation field

[0004]

[0001] The present innovation relates to an arrangement for the construction of platforms for landing and charging electric aerial vehicles, more specifically a base for the landing and takeoff of electric aerial vehicles based on platforms, which can be either fixed or modular and mobile, equipped with rechargeable batteries, including plug-in type connections and induction charging systems, in addition to the integration of alternative energy technologies to power the platforms.

[0005] History of innovation

[0006]

[0002] Major companies in the aeronautical and automotive sectors are advancing in the large-scale production of electric aerial vehicles, or "Electric Vertical Take-Off and Landing" - eVTOL, popularly known as 'flying cars', which would be electric aircraft capable of vertical take-off and landing.

[0007]

[0003] Most current projects are powered by batteries, although some projects use hydrogen fuel cells. Currently, batteries suffer from low specific power, causing range and consequently safety problems. Fuel cells have previously suffered from lower specific power, which could be too low for vertical takeoff / landing, but more recent projects claim to have solved this problem with much higher specific power. There are also proposals for the use of batteries for takeoff / landing and hydrogen fuel cells for cruise flight.

[0008]

[0004] Given this progress, there is a need to establish points, whether mobile or fixed (bases / platforms), that not only facilitate the landing and takeoff of these innovative vehicles, but also offer an efficient system for the automatic recharging of batteries while they remain at the landing points.

[0009]

[0005] Thus, the current urban aviation landscape is on the verge of transformation with the introduction of these electric vertical takeoff and landing (eVTOL) aircraft, which promise to revolutionize urban transport by offering sustainable and efficient air mobility solutions. However, the existing landing and takeoff infrastructure is not prepared to accommodate this new class of vehicles, mainly due to its rigidity and inability to adapt quickly to different types and sizes of eVTOLs.

[0010]

[0006] Traditional landing and takeoff sites are built to fixed specifications and have little or no post-construction adaptability. This presents a significant problem, as the variety of eVTOLs under development has a range of distinct operational requirements. Furthermore, the rapid evolution of eVTOL technology and changes in aviation regulations demand a flexible infrastructure that can adapt without major reconstructions or costly renovations.

[0011]

[0007] Another problem is the need for efficient charging systems to meet the challenge of efficient charging for eVTOLs in rural areas or areas with limited energy infrastructure, requiring innovative and adaptive solutions.

[0031] Detailed description of the innovation

[0032]

[0026] The present innovation deals, in summary, with a base (1), illustrated in Figures 1 and 9 in a first preferred configuration, intended for receiving electric aerial vehicles (eVTOLs) for landing and takeoff, while also enabling the electric charging of their batteries, allowing the vehicles to be quickly prepared for the next trip, optimizing operational efficiency.

[0033]

[0027] The equipment aims to recharge the batteries of electric flying cars by means of bases (1), configured as fixed or mobile platforms, equipped with batteries (5) that are recharged by means of sustainable technologies, such as solar panels (9) or wind turbines. In addition, such bases (1) are equipped with advanced charging technology, including both an induction charger (3) and a cable connection (7), among other solutions.

[0034]

[0028] The proposed innovation thus embodies a modular solution for landing and takeoff platforms, in an adaptable configuration capable of meeting the variable needs of eVTOLs. This modular system allows the creation of platforms (1) that can be easily altered in shape and size, thanks to a mechanical fitting system (8), which uses snap-fit ​​latches with fastening handles for quick assembly and disassembly.

[0029] Each module (2), illustrated in Figure 2 in a first preferred configuration, can accommodate different devices necessary for the operation of the platform (1), such as an induction charger (3), a programmable logic controller - PLC (4), batteries (5), a converter (6), a cable connection (7), solar panels (9) or any other devices that can be associated to assist in the operation of the equipment.

[0035]

[0030] The modular base (1) can take on an octagonal, round, square or any other shape required, adapting to the environment and technical specifications of the different eVTOLs. This not only solves the problem of the rigidity of existing landing and takeoff facilities, but also significantly reduces the costs and time associated with infrastructure reconfigurations.

[0036]

[0031] For this purpose, the fitting (8) between the modules (2) is carried out by means of a locking system with fastening handles, illustrated in Figure 8. This solution allows for a quick and secure union, providing a firm and stable connection between the modular sections (2), which begins with the alignment of the coupling interfaces of each module (2) and the insertion of the locking latches into the corresponding handles. The activation of the latch is manual and intuitive, requiring only a simple movement that fits and locks the modules (2) with an audible click that indicates secure fastening.

[0037]

[0032] This locking mechanism is designed to withstand the dynamic forces typical of landing and takeoff operations, maintaining the integrity of the platform (1) even under high loads and vibrations. In addition, the locking latches allow not only a secure fit but also quick disassembly when necessary, as disengagement is equally simplified, performed by lifting the locking handle, releasing the locking mechanism, allowing the modules (2) to be effortlessly decoupled.

[0033] Induction charging (3) emerges as a suitable technology to meet the demand for efficient and contactless charging solutions for manned electric flying vehicles, comprising polyphasic electromagnetic coils that are designed to induce an intense magnetic field, generated when an alternating electric current passes through the coils, establishing a magnetic energy flow capable of traversing the air and reaching the receiver coils in the eVTOL.

[0038]

[0034] The charger (3) is capable of producing a power density of up to 1.5 MW / m 2 , significantly exceeding the capabilities of conventional charging systems, ensuring that charging times are drastically reduced, facilitating a rapid turnover for eVTOLs in operation.

[0039]

[0035] Eliminating the need for physical connectors minimizes maintenance requirements and improves system reliability by eliminating common mechanical failure points in traditional connections.

[0040]

[0036] The effectiveness of this contactless charging approach is complemented by a cable charging option (7), similar to the systems used in electric cars, a method that is particularly useful for situations where fast charging is required, offering eVOLT operators greater flexibility and the ability to maximize operational efficiency during periods of high demand or in conditions where inductive charging (3) may not be feasible.

[0041]

[0037] The combination of these two loading methods ensures that the infrastructure can meet diverse operational needs, keeping the platform (1) adaptable and prepared.

[0042]

[0038] The operational effectiveness of the eVTOL landing and takeoff base (1) depends directly on maintaining a safe and dry surface. To this end, a drainage system was developed emphasizing functionality and simplified maintenance through the use of linear drains equipped with clip retainers, designed to maximize water flow efficiency, strategically located on the longitudinal edges of the modules (2). This facilitates the rapid capture and redirection of rainwater and other fluids away from the operational area. A slight slope towards the drains ensures that the water is directed to the drainage points, eliminating the formation of puddles and keeping the landing surface safe for eVTOL operations.

[0043]

[0039] An important element for the drainage system are the drains, located at the junction between the modules (2), equipped with clip-type retainers, which offer a quick and safe assembly and disassembly solution for the grates that cover the drains. This solution allows easy access for cleaning and maintenance, ensuring that the drainage system operates at maximum efficiency. The clip retainers allow the grates to be quickly fitted over the linear drains, ensuring a secure and resistant closure against the forces generated by landing and takeoff operations, as well as adverse weather conditions.

[0044]

[0040] Safety on the surface of eVTOL landing and take-off platforms is a top priority, especially in adverse weather conditions that can make surfaces slippery. To combat this challenge, a non-slip flooring solution consisting of an aluminum checker plate is employed, configuring a gridded floor (10), which not only increases safety but also contributes to the durability and aesthetics of the site, as well as protecting the modules (2) and their components - such as the solar panels (9).

[0045]

[0041] This “checkerboard pattern” on the gridded floor surface (10) creates a non-slip effect, increasing traction and significantly reducing the risk of slipping or even falling, essential for operator safety and eVTOL stability during landing and takeoff operations.

[0046]

[0042] The use of solar panels (9) in conjunction with batteries (5) for energy storage represents a key solution for the sustainable supply of energy on eVTOL landing and takeoff platforms (1). This configuration not only maximizes the use of solar energy, but also ensures the constant availability of energy for platform (1) operations, including eVTOL charging.

[0047]

[0043] The charging system consists of the association of solar panels (9) with storage batteries (5), located in modules (2) that form the platform structure. The 'off-grid' converter (6) plays a crucial role in converting the direct current (DC) generated by the solar panels (9) and stored in the batteries (5) into alternating current (AC), which is the format required for most platform (1) operations and for charging eVTOLs.

[0048]

[0044] The "off-grid" converter (6) receives direct current from the batteries (5) and converts it into alternating current, in a process controlled by a power management system that optimizes conversion efficiency, ensuring that energy is available in the form and at the time required for platform operations and vehicle charging.

[0049]

[0045] The energy, once converted into alternating current, is distributed through the platform’s electrical infrastructure (1) to power lighting, security systems, communication equipment and provide the necessary load for the eVTOLs.

[0050]

[0046] The interconnection and operation process consists of capturing and converting solar energy by the panels (9) and converting it into direct current, flowing directly to the battery storage system (5). The efficiency in conversion is maximized by the use of advanced photovoltaic technology, ensuring that a significant amount of solar energy is converted and stored.

[0051]

[0047] For energy storage, batteries (5) are used, housed in docking compartments designed under modules (2) of the platform (1), interconnected by cables to the solar panel system (9). These compartments are accessible for maintenance, but also safe and protected from the elements and external interference.

[0052]

[0048] The infrastructure required to support the landing and takeoff operations of manned electric flying vehicles requires highly efficient and adaptive management. In this context, the programmable logic controller - PLC (4), also known as "programmable logic controller (PLC)", plays a crucial role, constituting an electronic device that combines equipment and programming to control industrial applications, operating in a manner similar to a computer, but specifically designed to control industrial and mechanical processes, a product that already exists on the market.

[0053]

[0049] eVOLT approach, landing and takeoff operations are efficiently managed by a PLC-based system (4). During approach, strategic sensors, including infrared and optical sensors, monitor critical data such as vehicle speed, altitude and trajectory. These sensors, which may include photographic cameras, spectrometers, radars and infrared sensors, collect data that is immediately processed by the PLC (4), which uses this information to adjust the navigation and safety systems, ensuring safe alignment with the landing zone.

[0054]

[0050] On landing, the PLC (4) continues to monitor and adjust parameters in response to environmental and technical conditions, keeping the base alert to activate emergency systems if necessary.

[0055]

[0051] During takeoff, after loading and maintenance, the PLC (4), through the sensors, checks the conditions of the eVOLT and coordinates the release of the takeoff area, ensuring that there are no physical or digital obstacles that could compromise the start.

[0056]

[0052] Protective bars (11) can be used, configuring themselves as elements to guarantee operational safety on the eVTOL landing and takeoff base (1). In the preferred configuration of the present innovation, depicted in Figure 9, the bars (11) are coupled in a snap-fit ​​manner to the edges of the platform (1), allowing for a safe and robust installation, while also offering the flexibility for adjustments or relocations as needed for operational requirements. This snap-fit ​​method ensures that the protective bars can be effectively integrated into the base structure (1), providing a reliable physical barrier.

[0057]

[0053] The base (1) of the present innovation may also include some additional features, such as: a) intelligent lighting system, with LED lights that adjust their intensity based on environmental conditions, assisting pilots during landings and takeoffs; additionally, such lights can be configured to show specific patterns when a vehicle is about to take off or land; b) hanging gardens, which allow nature to be incorporated into the bases, not only for aesthetics, but also to help purify the air and create a more pleasant environment; c) noise reduction system, with sound barriers or specific construction materials that minimize vehicle noise to the surroundings; d) integrated weather station, to provide real-time weather data, helping pilots make informed decisions about landings and takeoffs.

[0058]

[0054] In addition to its functional characteristics, the basis of this innovation also has a "futuristic" aspect, with geometric shapes, reflective glass and metal structures that give it an advanced and contemporary look, as well as the provision for integration with the environment, whether it is an urban or rural area, using materials that complement the natural landscape.

[0059]

[0055] The base (1) allows customization of its appearance, including painting, marking and integration of signaling and lighting systems, according to specific customer requirements or local regulations.

[0060]

[0056] In summary, the proposed innovation is designed to solve the challenges faced by eVTOL landing and takeoff infrastructure, setting the stage for the new era of urban air transport. With its adaptability, efficiency, and innovative design, it offers the flexibility needed to keep pace with technological and regulatory evolution, while presenting a sustainable and practical solution to the challenges of the present and the future.
