Compartmentalized structure for the acoustic treatment and the de-icing of an aircraft nacelle and aircraft nacelle incorporating said structure

摘要

An acoustic structure for an aircraft nacelle which comprises an acoustically resistive substructure, at least one layer of cells and a reflective layer. The acoustic structure comprises at least one single-piece substructure which divides up the layer of cells and which incorporates elongated elements of a de-icing system.

1. An acoustic structure for an aircraft nacelle, comprising, moving away from an axis of the nacelle,
an acoustically resistive substructure, at least one layer of cells, a reflective layer, elongated elements of a de-icing system, first partitions arranged in transverse planes, a plurality of acoustic caissons juxtaposed with one another on at least a part of a periphery of the nacelle,
each acoustic caisson being delimited by tight lateral walls arranged in longitudinal planes,each acoustic caisson comprising at least one single-piece substructure to divide up the layer of cells which comprises:at least one of the first partitions or first parts of the first partitions linked to the acoustically resistive layer, linked together by at least a part of the lateral walls of the acoustic caisson,at least a part of the lateral walls of the acoustic caisson, andthe elongated elements of the de-icing system.
