Problems solved by technology

[0004] There are some square box parts on the plane. Most of these boxes are assembled by welding or riveting. The former method is easy to leave welding marks, and the edges need to be polished later, while the latter needs to be fixed with rivets. Design a new type of box structure that can be combined without welding or rivets

Abstract

The invention relates to the technical field of airplane structural design, specifically to an airplane box body structure. The airplane box body structure comprises a No. 1 plate, a No. 2 plate, a No. 3 plate, a No. 4 plate and a No. 5 plate. The invention provides the airplane box body structure; by using an unfoldable conjoined design, four plates are hinged at the four edges of the No. 1 plateto form a main body structure; the four plates correspond to each other in pairs and are clamped and fixed through corresponding clamping heads and clamping grooves; the airplane box body structure is convenient to mount and mold without using a welding machine or a rivet; in addition, the four hinged plates are provided with folded edges so that connection areas between the four plates and a skin are guaranteed; and gaps exist between the folded edges after the box body is mounted so that a certain deformation space is provided to delay a situation skin cracks caused by pressure applied to the box body.

Description

technical field [0001] The invention relates to the technical field of aircraft structure design, in particular to an aircraft box structure. Background technique [0002] Aircraft refers to a heavier-than-air aircraft that has one or more engines to generate forward thrust or pull, and the fixed wings of the fuselage to generate lift, and fly in the atmosphere. [0003] The airplane is one of the most important inventions in the early 20th century. Since the invention of the airplane, the airplane has increasingly become an indispensable means of transportation for modern civilization. [0004] There are some square box parts on the plane. Most of these boxes are assembled by welding or riveting. The former method is easy to leave welding marks, and the edges need to be polished later, while the latter needs to be fixed with rivets. Design a new type of box structure, which can be combined without welding or rivets. Contents of the invention [0005] (1) Solved technica...
