Problems solved by technology

In the equipment area that needs frequent maintenance, the quick-release non-load-bearing cover is usually selected in the opening area according to the actual situation. In order not to affect the force transmission, it is often only possible to retain the normal stress-bearing members in the opening area and strengthen the frame structure according to the actual situation. , which will affect the access and increase the weight of the structure; in equipment areas that require regular maintenance but infrequent overhaul, the cover is usually designed as a normal stress cover, and the entire normal stress cover needs to be removed during maintenance , which takes a long time and affects maintainability
When there are equipments that need to be repaired frequently in the equipment area that requires regular maintenance, the normal stress-bearing cover is usually used. In this way, the entire normal stress-bearing cover has to be opened for each maintenance, which prolongs the maintenance time and increases the workload during maintenance. Affect the maintainability of the equipment

Abstract

The invention relates to the improvement of an aircraft cover cap, in particular to a quick detachable combined cover cap capable of bearing stress. The cover cap comprises a positive stress bearing cover cap and a quick detachable cover cap, and is characterized in that the quick detachable cover cap is installed at the opening in the positive stress bearing cover cap; the shape of the quick detachable cover cap is matched with that of the opening installed in the positive stress bearing cover cap, and the quick detachable cover cap is connected with the positive stress bearing cover cap through a hinge and a bearing lock at the opening of the positive stress bearing cover cap so as to cover the opening in the positive stress bearing cover cap. The adoption of the combined cover cap formof the positive stress bearing cover cap and the quick detachable cover cap guarantees the structural strength need and the maintainability need of the aircraft and facilitates the installation and maintenance of the aircraft, without affecting the structural weight of the aircraft.

Description

technical field [0001] The invention relates to the improvement of the structure of an aircraft hatch, in particular to a load-bearing quick-release combined hatch. Background technique [0002] When large flaps need to be designed for installation and maintenance on the mechanical structure of the aircraft, there are usually two types of quick-release non-loaded flaps and normal stress-bearing flaps. In the equipment area that needs frequent maintenance, the quick-release non-load-bearing cover is usually selected in the opening area according to the actual situation. In order not to affect the force transmission, it is often only possible to retain the normal stress-bearing members in the opening area and strengthen the frame structure according to the actual situation. , which will affect the access and increase the weight of the structure; in equipment areas that require regular maintenance but infrequent overhaul, the cover is usually designed as a normal stress cover, ...
