Abstract
A combustor heat shield panel has interior and exterior surfaces with a number of circuitous non-interconnected cooling gas passageways having inlets on the exterior surface and outlets on the interior surface.
Claims16
A metal laminate combustor heat shield panel comprising:
- an interior surface;
- an exterior surface;
- and
- a plurality of cooling gas passageways non-interconnected with each other and having inlets on the exterior surface and outlets on the interior surface, the passageways lacking line of sight clearance between inlet and outlet along a majority of an area of at least one of the inlet and outlet, wherein the metal laminate is formed generally as a frustoconical segment and comprises:
- a first layer forming the exterior surface;
- a second layer forming the interior surface;
- and
- an intermediate layer cooperating with the first layer and second layer to form turns in the passageways.
