Abstract:
1. A gas turbine combustion chamber assembly comprising: an inner metal casing; an outer metal casing; an annular combustion chamber having an inner wall and an outer wall of ceramic matrix composite material and a chamber end wall connected to the inner and outer walls; and elastically-deformable link elements connecting the inner wall and the outer wall of the chamber respectively to the inner metal casing and to the outer metal casing, wherein each of the inner and outer walls of the chamber is subdivided circumferentially into adjacent sectors along longitudinal edges, each sector extending continuously from the chamber end wall to the opposite end of the chamber, each sector being folded outwards from the chamber via each of its longitudinal edges so as to form a portion having a U-shaped cross-section, each terminated by a folded-back margin that is spaced apart from the outer face of the corresponding chamber wall, and the link elements are connected to the inner and outer walls of the chamber by being fastened to the margins of the sectors.
