Embodiment Construction

[0025] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0026] Such as Figure 1 to Figure 7 As shown, the wing fuel tank includes a spar 1 and a skin 2 arranged on the spar 1, wherein the spar 1 is a glass fiber plastic composite material, and the skin 2 is a carbon fiber composite material, which meets the structural strength and light weight .

[0027] The spar 1 is a double spar arranged front and rear, that is, a front spar and a rear spar arranged side by side. The beams are connected by parts in the wing, such as the landing gear mounting frame and the baffle, without the need for many connecting ribs, the structure is simple and the weight is light.

[0028] The cross-section of the spar 1 is C-shaped, and the opening of the spar is inward, which is convenient for the positioning of parts between the two spars. The body is connected, and ...

Abstract

The invention discloses a wing oil box. The wing oil box comprises wing beams. The wing beams are double-wing beams arranged in a front-back abreast mode. A sealed whole wing oil box is vertically formed through a sealing plate between the double-wing beams. The oil box is divided into a group of areas in the length directions of the wing beams through a set of baffles arranged abreast in the whole wing oil box. The adjacent areas communicate with one another through communicating holes formed in the baffles. According to the wing oil box, the structural design is reasonable, the whole wing oil box is divided into the several areas through the baffles, all the areas communicate with one another through the communicating holes, reciprocating motion of fuel oil of the wing fuel oil box is prevented when a plane is unstable, the stability of flying of the plane is ensured, the ends of the baffles are connected with the wing beams, and the structural strength of a wing is improved.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a wing fuel tank. Background technique [0002] The wing structure of the existing basic trainer aircraft is complicated, and there are many independent fuel tanks in the wings, and the fuel tank is positioned and fixed by a fixed structure. , affecting the stability of the aircraft. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a wing fuel tank to achieve the purpose of reducing the fuel oil in the fuel tank shaking when the aircraft is unstable. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] The wing oil tank includes a wing spar, and the wing spar is a double wing spar arranged side by side. A sealed integral wing oil tank is formed by a sealing plate up and down betwe...
