Title (EN) EXHAUST CONE WITH ACOUSTIC ATTENUATION SYSTEM
(FR) CÔNE D'ECHAPPEMENT AVEC SYSTEME D'ATTENUATION ACOUSTIQUE
Abstract: front page image
(EN)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).
(FR)L'invention concerne un cône d'échappement (1) de moteur aéronautique s'étendant d'amont en aval suivant un axe longitudinal. Le cône (1) comprend un noyau structural (10) en matériau composite formé d'une pièce axisymétrique (11) comportant à son extrémité amont un flaque amont (12) et à son extrémité aval un flasque aval (13), le noyau assurant la résistance structurale du cône. Le cône comprend en outre un système d'atténuation acoustique (20) réalisé en matériau composite et fixé sur le noyau structural (10).
