Anti-transverse impact large opening cabin structure and aircraft with same

Abstract

The present invention provides a cabin structure with large openings against lateral impact and an aircraft with the same, wherein the cabin structure includes: a cabin shell with a large opening, a number of reinforcement and stability maintenance components, any reinforcement and stability maintenance components along the large opening It is arranged in the width direction, including first and second supports and a support adjustment part, wherein the first end of the first support is connected to the first end of the support adjustment part, and its second end is connected to the second support located on the side of the large opening. A housing side wall is connected; the first end of the second support member is connected to the second end of the support adjustment part; its second end is connected to the second housing side wall opposite to the first housing side wall; Under lateral impact, the support force adjustment unit adjusts the support force of the first and second supports based on the deformation degrees of different parts of the first and second shell side walls to achieve continuous cabin structural stiffness and deformation coordination. It can solve the problem that it is difficult to guarantee the strength, rigidity and stability of the large opening cabin section under the action of transverse impact load.

Description

technical field [0001] The invention relates to the technical field of aircraft mechanical structures, in particular to a transverse impact-resistant large-opening compartment structure and an aircraft having the same. Background technique [0002] During the design process of aircraft cabin structure, various hatches of different sizes and shapes are inevitably opened due to the requirements of installation, use and maintenance of internal equipment. The small opening does not destroy the force transmission route of the load, such as the inspection hole on the beam and rib web, the small observation hole on the skin, etc.; the middle opening destroys the local force transmission route of the load, and cuts off a small amount of long In general, it has no major impact on the force transmission route, such as the windows of passenger aircraft, boarding doors, etc.; the large opening cuts off the skin, stringers and even the bulkhead, completely destroying the force transmissi...

AI Technical Summary

Problems solved by technology

However, for the above-mentioned large-opening cabins, due to the functional requirements, it is impossible to adopt the forced-type cover compensation method. Blindly increasing the wall thickness of the cabin section to improve the strength under lateral impact load will greatly increase the quality of the cabin section and affect the overall performance.
