Abstract:
1. An annular combustion chamber assembly for a gas turbine, the assembly comprising: an inner metal casing; an outer metal casing; an annular combustion chamber mounted between the inner and outer casings and comprising an annular inner wall and an annular outer wall of ceramic material together with a chamber end wall connected to the inner and outer walls and provided with orifices for receiving injectors; and elastically-deformable link parts supporting the combustion chamber between the inner metal casing and the outer metal casing; the assembly formed by the inner wall, the outer wall, and the end wall of the combustion chamber being subdivided circumferentially into adjacent chamber sectors, each comprising an inner wall sector, an outer wall sector, and a chamber end sector interconnecting the outer and inner wall sectors; wherein each chamber sector is made as a single piece of ceramic composite material, wherein elastically-deformable link parts connect the inner metal casing and the outer metal casing respectively to each inner wall sector of the combustion chamber and to each outer wall sector of the chamber, and wherein a one-piece ring is also provided in contact with the chamber end wall sectors and to which the chamber sectors are connected.
