Abstract:
A cabin interior assembly for an aircraft having a primary airframe structure which supports vibrating components at substantially the top of the aircraft structure, the cabin interior assembly comprising:a shell structure located within the airframe structure, the shell structure including a plurality of axially spaced bell frames, each bell frames being unitary and extending from one side of the cabin interior assembly, across the ceiling and down to the other side of the cabin interior assembly, each pair of adjacent bell frames having at least two longitudinal support members attached to and extending between the bell frames;a plurality of panels mounted to the shell structure, the edges of adjacent panels forming a butt joint so that each panel is independently removable from the shell structure; anda plurality of isolators adapted to be disposed between the shell structure and the airframe structure, each isolator having a cabin isolator component mounted to a lower end of a bell frame so as to be distantly spaced from the vibrating component when the shell structure is mounted to the airframe structure, the cabin isolator component adapted to mate with a frame isolator component mounted on the airframe structure, the isolator operative for attaching the shell structure to the airframe structure and for reducing vibratory transmission from the airframe structure to the shell structure.
