Description

Technical Field

[0001] This utility model relates to the field of aircraft parking and maintenance building technology, specifically to an openable and retractable eVTOL hangar. Background Technology

[0002] In recent years, with the progress of social economy and the widespread application of various low-altitude aircraft and drones, the low-altitude economy has emerged. The low-altitude economy refers to a comprehensive economic form that takes various low-altitude flight activities of various manned and unmanned aircraft as the driving force and radiates to promote the integrated development of related fields. It involves multiple industries and application scenarios, and its products include drones, helicopters, electric vertical take-off and landing aircraft, etc.

[0003] The development of the low-altitude economy has driven the development of various types of aircraft. eVTOL is an abbreviation for electric vertical take-off and landing aircraft, which can be simply understood as an electric aircraft that can take off and land vertically without a runway. Currently, most eVTOL aircraft hangars in China have openings at both ends, which is inconvenient for vertical take-off and landing aircraft. Moreover, they are mostly steel frame structures with external steel enclosures. The construction of such steel structure hangars is extremely time-consuming and labor-intensive, requiring the construction of various complex space frames. The frame structure is poor in aesthetics and practicality in order to meet load requirements, and the construction cycle is long. The steel structure hangar frame requires welding, and the various welding processes can lead to safety and quality problems. Compared with aluminum structures, steel structures are heavier, consume more materials, and have poorer corrosion resistance, which will greatly increase the initial investment cost and the later maintenance cost. In addition, steel structure hangars cannot be moved or disassembled after construction, resulting in extremely low flexibility. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing an openable eVTOL hangar, which reduces the construction cost of eVTOL aircraft hangars, increases installation efficiency, enhances hangar practicality, and promotes social and economic development.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An eVTOL hangar with an openable roof has an overall peach-shaped appearance. The main body consists of an I-beam aluminum frame at both ends and several openable roof sections in the middle. The bottom of the openable roofs moves on sliding rails on both sides of the hangar. The height of the openable roofs is higher than the top of the I-beam aluminum frame at both ends. The I-beam aluminum frame is entirely enclosed by membrane fabric. Emergency doors and maintenance access doors are set on the front and rear sides of the hangar main body.

[0007] The main body of the hangar has two hinged, openable roofs in the middle.

[0008] A fresh air system is installed inside the aforementioned warehouse.

[0009] The above-mentioned membrane is made of high-strength PVDF membrane material, namely polyvinylidene fluoride membrane.

[0010] The overall appearance of this aircraft hangar is peach-shaped. The main frame is an I-beam aluminum profile structure, which is integrally extruded and formed. The frame is made of two kinds of connecting plates connected by bolts and anti-loosening nuts. Each frame is connected and fixed by cross braces (beams) to form a span. Each span is connected according to technical requirements to form the entire aircraft hangar. The aircraft hangar is not connected by welding and has no weld points. After the overall frame is built, it is filled with thermal insulation material and then covered with inner and outer PVDF membrane materials to enclose the entire building, forming an indoor storage (maintenance) space that is both windproof and rainproof and heat-insulating.

[0011] During installation, the top of the middle movable frame should be higher than the tops of the frames at both ends to allow for sufficient sliding space and openings. The size of the openings can be adjusted or customized according to the type of aircraft. Considering the sliding opening and closing function, the ground rail device should be considered in advance before installing the frame to ensure accurate positioning and reduce the risk of use.

[0012] A complete aircraft hangar includes various infrastructure such as emergency doors, ventilation windows, and vent locations; a control room or monitoring room can be set up separately at the edge or corner of the aircraft hangar; and standard electrical lighting and switches and sockets are provided in the inclined beams and curved columns to ensure sufficient interior space.

[0013] In addition to being made entirely of aluminum alloy, the main frame of the aircraft hangar also has multiple functions. The hangar door is made of aluminum frame and is treated with weatherproof and sealing treatment to effectively insulate heat. It adopts a sliding opening and closing design and is equipped with sliding rails on the ground. It can be electrically controlled to meet the landing needs of various aircraft. The interior is equipped with a fresh air system and is equipped with a tensionable PVDF membrane to enhance the overall load-bearing capacity of the facility.

[0014] This utility model hangar can be customized in terms of main frame span according to the size of the aircraft, and adopts a movable, closed-roof structure to facilitate the storage of various vertical takeoff and landing aircraft or helicopters. It provides a comfortable storage environment for all types of aircraft and has the advantages of low construction cost, ease of use, and robust structure. Attached Figure Description

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a retractable eVTOL hangar has an overall peach-shaped appearance. The main body consists of two I-beam aluminum profile frames 1 at both ends and two retractable roofs 5 in the middle. The bottom of the retractable roofs 5 moves on sliding rails 4 on both sides of the hangar. The height of the retractable roofs 5 is higher than the tops of the I-beam aluminum profile frames 1 at both ends. The I-beam aluminum profile frames 1 are entirely enclosed by a membrane fabric 6, which is made of high-strength PVDF membrane material, i.e., polyvinylidene fluoride membrane. An emergency door 2 and a maintenance access door 3 are provided on the front of the hangar. A fresh air system is installed inside the hangar. The aircraft hangar is peach-shaped overall, with emergency doors and maintenance access doors on the gable walls at both ends, accommodating the daily entry and exit of goods and maintenance vehicles. The opening dimensions of the retractable roofs 5 can be customized according to the type of aircraft stored, meeting the storage requirements of various eVTOL aircraft 7.

[0022] This utility model aircraft hangar has an overall peach-shaped structure with steep slopes on both sides, ensuring minimal water and snow accumulation during rain, snow, or extreme weather, and exhibiting exceptional wind and snow resistance. The structure is made of aluminum alloy, which, compared to steel structures, offers superior corrosion resistance, ease of processing, rust resistance, and lightweight construction, resulting in lower construction costs and investment. The entire structure is weld-free, secured entirely with bolts and nuts, ensuring structural stability, convenient installation, and rapid construction. Compared to steel structures, it offers unparalleled flexibility, allowing for quick assembly, disassembly, and relocation. The frame utilizes a special I-beam aluminum cross-section, with unique cylindrical shapes at both ends reducing the contact area between the adhesive rods and the profiles, minimizing friction, enhancing grip, and facilitating membrane fabric removal and installation. External slots on the I-beam aluminum profiles allow for the installation of pre-fabricated insulation shells, reducing thermal bridging and extending the building's lifespan. The membrane fabric of the entire aircraft hangar can be tensioned and adjusted using jacks, effectively extending its lifespan and improving overall structural strength. The new hangar can be customized in span to accommodate different aircraft dimensions and features a movable, closed-top design, facilitating the storage of various vertical takeoff and landing aircraft or helicopters. Provide a comfortable storage environment for all types of aircraft.
