Description

Technical Field

[0001] This utility model relates to the field of fixed-wing aircraft technology, and more specifically, to a quick-release structure for the main wing fuel tank of a fixed-wing aircraft. Background Technology

[0002] Conventional fixed-wing aircraft require runways for takeoff and landing, which places high demands on the site and significantly limits their use. Rotary-wing aircraft, on the other hand, typically have low speeds and short flight times, further restricting their applications. In recent years, vertical takeoff and landing (VTOL) aircraft have seen significant development. VTOL aircraft combine the vertical takeoff and landing capabilities of rotorcraft with the high forward speeds of fixed-wing aircraft, offering broad application prospects.

[0003] The endurance and payload capacity of a fixed-wing aircraft are important aspects of evaluating its performance. The endurance of a fixed-wing aircraft is limited by the amount of fuel it carries; simply put, increasing endurance requires carrying more fuel. However, the fuel tanks of these fixed-wing aircraft are mostly designed as integral structures, which occupy a large amount of space on the airframe platform and are not convenient to disassemble.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a quick-release structure for the main wing fuel tank of a fixed-wing aircraft to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A quick-release structure for a fuel tank on the main wing of a fixed-wing aircraft includes a main wing and a fuel tank, as well as a connecting mechanism for connecting the main wing and the fuel tank.

[0008] The connecting mechanism includes a fuel tank fixing component. A mounting groove for installing the fuel tank fixing component is provided on one side of the fuel tank. A main wing fixing component is provided on one side of the fuel tank. A wire plug is provided on the side of the main wing fixing component away from the main wing. The wire plug is connected to the main wing fixing component through a wire plug fixing component. A second wire plug that is compatible with the first wire plug is provided in the mounting groove.

[0009] Preferably, the second wire plug is connected to the fuel tank via the second wire plug fixing member.

[0010] Preferably, the fuel tank is provided with a fuel tank plug cover on the side away from the main wing, and the bottom end of the fuel tank plug cover is provided with a skid.

[0011] Preferably, the first cable plug fixing component is connected to the fuel tank fixing component by a screw, and the second cable plug fixing component is connected to the fuel tank fixing component by a screw.

[0012] Preferably, the front of the fuel tank is provided with an LED light, and the LED light is provided with a lampshade.

[0013] The beneficial effects of this utility model are as follows: the double-snap fastening of the fuel tank fixing component and the main wing fixing component makes the fuel tank installation more secure; the precise guidance during installation makes the connection between the wire plug and the installation smoother; the wire plug can be quickly plugged and unplugged without screws; an LED light is installed at the front of the fuel tank; and a skid is installed at the bottom of the fuel tank, which can play a protective role when the aircraft lands.
