Abstract (en)

The combustion chamber for an aircraft gas turbine engine has inner (28) and outer (26) composite walls and a metal base (30) held in position by the walls. The base fixings extend across annular cavities (42,44) which receive the cylindrical sections of the ends of the walls. This defines a play between the peripheral edges of the base and the returned sections (46,48) and the opposing surfaces of the walls. This allows a radial expansion of the chamber base with respect to the walls.
