OVER-FRAME BLANKET ASSEMBLIES AND METHODS OF INSTALLATION IN FUSELAGE ASSEMBLIES

摘要

Fuselage assemblies, over-frame blanket assemblies, and methods of installing over-frame blanket assemblies are provided. A fuselage assembly for an aircraft includes a fuselage skin, a cabin liner, and an over-frame blanket assembly. The cabin liner has an outer side facing the fuselage skin. The over-frame blanket assembly is disposed between the fuselage skin and the cabin liner and has a first blanket piece. The first blanket piece includes a first sound barrier layer that defines a first outer surface of the over-frame blanket assembly and a first sound absorbing layer that defines a second outer surface of the over-frame blanket assembly facing the fuselage skin. A method of installing the over-frame blanket assembly incudes positioning the first blanket piece in an orientation such that the first sound barrier layer is directly adjacent the cabin liner.
