Abstract

L'invention concerne une chambre annulaire de combustion (8) pour turbomachine (7), comportant deux parois annulaires coaxiales radialement interne et externe (9, 10) reliées en amont (AM) par une paroi annulaire de fond (11) de chambre, et reliées en aval (AV) via des brides (12, 13) de fixation à des carters interne et externe, caractérisée en ce que les parois annulaires radialement interne et externe (9, 10) sont formées d'une pluralité de secteurs et en ce que : - les secteurs sont agencés circonférentiellement bout à bout par emboîtement avec jeu circonférentiel et radial de chacun des bords longitudinaux d'un secteur avec un bord longitudinal d'un secteur adjacent ; et/ou - les bords aval (17) des parois annulaires interne et externe (9, 10) coopèrent par emboîtement avec jeu axial et radial, avec des extrémités (22) des brides (12, 13).
