Problems solved by technology

In addition, due to the manufacturing gap between the bolt and the hole wall and the deformation of the hole wall that may be caused by the compression between the two when loaded, there may be a slight slip between the connecting strip plate and the wing wall

Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0025] see figure 1 , figure 1 It is a schematic diagram of the docking structure between two wing panels in the prior art.

[0026] like figure 1 As shown, the butt joint structure of wing panels 1 includes: two wing panels 1 , connecting straps 2 and fasteners 3 . The two wing panels 1 are the first wing panel 1 and the second wing panel 1 to be connected. The two wing panels 1 are arranged opposite to each other a...

Abstract

The embodiment of the invention discloses a wing wallboard 1 butt-joint structure and belongs to the technical field of aircraft structures. The wing wallboard butt-joint structure comprises two wing wallboards 1 to be butt-jointed, connecting belt plates 2 attached to the two wing wallboards 1 correspondingly, and fastening pieces 3 used for fixedly connecting the wing wallboards 1 and the connecting belt plates 2. A plurality of first concave-convex engaging layers 11 are arranged on the faces, attached to the connecting belt plates 2, of the wing wallboards 1. A plurality of second concave-convex engaging layers 21 are arranged on the faces, attached to the wing wallboards 1, of the connecting belt plates 2. The first concave-convex engaging layers 11 and the second concave-convex engaging layers 21 are engaged mutually. According to the wing wallboard butt-joint structure, the requirement for high-strength bolts is greatly lowered, the safety margin is improved, and possible slippage between the connecting belt plates 2 and the butt-jointed wing wallboards 1 can be effectively lowered, so that the connecting rigidity of the butt joint zone is improved.

Description

technical field [0001] The invention relates to the technical field of aircraft structures, in particular to a butt joint structure of wing panels. Background technique [0002] In the field of aircraft manufacturing, the connection between the wing and the fuselage, the connection between different spar sections, etc. are all key parts in the composite aircraft structure. The commonly used connection method in the prior art is to use bolts to connect different wing panels (central wing / outer wing) or spar sections through connecting strips or corner boxes. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems: [0004] In the prior art, when connecting different wing panels with bolts, the friction between the connecting strip and the wing panels is usually ignored, that is, all loads on the wing panels are considered to be It must be passed to the connecting strap plate via bolts. That is to say, th...
