Title:
FLEXIBLE CONNECTING STRUCTURE FOR ARRESTING WALL AND FUSELAGE, AND AIRPLANE
Document Type and Number:
WIPO Patent Application WO/2023/202055
Kind Code:
A1
Abstract:
A flexible connecting structure (100) for an arresting wall and a fuselage. The flexible connecting structure is configured to fix an arresting wall (200) to the interior of an aircraft (300), and comprises: a first connecting joint (10), the first connecting joint (10) being pivotally connected to a second connecting joint (201) arranged on the arresting wall; a flexible transition member (20), a first end (21) of the flexible transition member being fixed to a free end (11) of the first connecting joint; and an interframe short beam (30), which is fixed to an adjacent frame (301) and stringer (302) on an aircraft panel and fixed to a second end (22) of the flexible transition member. The structure can bear, by means of the flexible transition member, a course load transmitted via the arresting wall to the fuselage of the aircraft, thereby effectively avoiding excessive constraint of a rigid arresting wall on deformation of structures such as local skin of the fuselage under a working condition of pressurization, and eliminating the influence on the fatigue performance of the structure of the fuselage.
