Abstract

Ensemble annulaire d’axe longitudinale pour turbomachine comprenant un carter externe entourant une chambre annulaire de combustion comprenant un fond de chambre annulaire comportant un rebord annulaire interne et un rebord annulaire externe, et deux viroles annulaires radialement interne et radialement externe coaxiales dont les bords amont sont appliqués sur les rebords annulaires interne et externe du fond de chambre annulaire. Le rebord annulaire externe du fond de chambre porte au moins un bossage s'étendant radialement vers l'extérieur et traversant le bord amont de la virole annulaire externe, ledit bossage recevant un organe de fixation du carter au bossage. Figure à publier avec l’abrégé : figure 3AAnnular assembly with a longitudinal axis for a turbomachine comprising an outer casing surrounding an annular combustion chamber comprising an annular chamber bottom comprising an internal annular flange and an external annular flange, and two coaxial radially internal and radially external annular shrouds, the upstream edges of which are applied to the inner and outer annular rims of the annular chamber bottom. The outer annular rim of the chamber bottom carries at least one boss extending radially outwards and crossing the upstream edge of the outer annular shroud, said boss receiving a member for fixing the casing to the boss. Figure to be published with abstract: Figure 3A
