Abstract

Le présent document concerne un ensemble de sortie d’un générateur de gaz comprenant un carter d’échappement en matériau métallique, un cône de sortie (16) en matériau composite à matrice céramique, et une bride annulaire (18) dont une partie aval comporte des pattes aval (24) fixées au cône de sortie (16) et une seconde extrémité amont est fixée au carter (10), caractérisé en ce qu’il comprend des moyens de limitation du transfert thermique entre les pattes aval de la bride (18) et le cône d’échappement (16). Figure à publier avec l’abrégé : Figure numéro 4This document relates to an outlet assembly of a gas generator comprising an exhaust casing made of metallic material, an outlet cone (16) made of composite material with a ceramic matrix, and an annular flange (18), a downstream part of which comprises downstream lugs (24) fixed to the outlet cone (16) and a second upstream end is fixed to the casing (10), characterized in that it comprises means for limiting the heat transfer between the downstream lugs of the flange (18 ) and the exhaust cone (16). Figure to be published with the abstract: Figure number 4
