A combustion chamber wall (46) is hollow, has a first surface (54) and a second surface (56) and comprises a plurality of polyhedron shaped chambers (58) defined by a matrix (60) of integral interconnected walls (62). The walls (62A) of the chambers (58A) in a first layer (A) define the first surface (54) of the combustion chamber wall (46) and the walls (62) of the chambers (58C) in a third layer (C) define the second surface (56) of the combustion chamber wall (46). The chambers (58) are fluidly interconnected by apertures (64) extending through the integral interconnected walls (62) of the chambers (58) for the flow of coolant (D) there-between. The walls (62A) of the chambers (58A) in the first layer (A) have apertures (64A) extending there-through to supply coolant (D) into the first layer (A) and the walls (62C) of the chambers (58C) in the third layer (C) have apertures (64C) extending there-through to supply coolant (D) from the third layer (C) into the combustion chamber. The combustion chamber wall (46) is manufactured by additive layer manufacture. |
