EXHAUST CONE WITH ACOUSTIC ATTENUATION SYSTEM

摘要

The invention relates to an aeronautical engine exhaust cone (1) extending from upstream to downstream along a longitudinal axis. The cone (1) comprises a structural core (10) made of composite material formed of an axisymmetric component (11) which at its upstream end has an upstream flange (12) and at its downstream end has a downstream flange (13), the core providing the cone with its structural strength. The cone further comprises an acoustic attenuation system (20) made of a composite material and attached to the structural core (10).
