Abstract
A combustion chamber wall is hollow, has a first surface and a second surface and includes a plurality of polyhedron shaped chambers defined by a matrix of integral interconnected walls. The walls of the chambers in a first layer define the first surface of the combustion chamber wall and the walls of the chambers in a third layer define the second surface of the combustion chamber wall. The chambers are fluidly interconnected by apertures extending through the integral interconnected walls of the chambers for the flow of coolant there-between. The walls of the chambers in the first layer have apertures extending there-through to supply coolant into the first layer and the walls of the chambers in the third layer have apertures extending there-through to supply coolant from the third layer into the combustion chamber. The combustion chamber wall is manufactured by additive layer manufacture.
