Abstract

A cabin interior assembly for an aircraft is disclosed, the aircraft having a primary airframe structure for supporting vibrating components. The cabin interior assembly includes a shell structure located within the airframe structure. The shell structure is formed from a plurality of axially spaced bell frames. Each bell frame is unitary and extends from one side of the cabin interior, across the ceiling and down to the other side. At least two longitudinal support members are attached to and extend between each adjacent pair of the bell frames. A plurality of panels are mounted to the shell structure with the edges of adjacent panels forming a butt joint as they overlap the bell frames and longitudinal support members. Isolators are disposed between the shell structure and the airframe structure. Each isolator includes a first component mounted to a lower end of a bell frame and a second component mounted on the airframe structure. The isolator is operative for attaching the shell structure to the airframe structure and for reducing vibratory transmission from the airframe structure to the cabin interior trim panel shell structure.
