Abstract
An annular combustion chamber has outer and inner axially-extending side walls of composite material and an end wall of metal material held in position on the outer and inner side walls by fixing means. Provision is made for the fixing means to pass through annular cavities that are designed to receive cylindrical end portions of the outer and inner side walls, and that are created between peripheral edges of the end wall and facing portions folded downstream, a determined amount of clearance J being provided between the peripheral edges and the facing faces of the outer and inner side walls in such a manner as to allow expansion to take place freely, in operation, in a radial direction between said end wall and said side walls.
