WALL ELEMENTS FOR GAS TURBINE ENGINE COMBUSTORS
First Claim
1. A combustor for a gas turbine engine, the combustor comprising an outer wall, an upstream end and a downstream end with fluid flow through said combustor progressing from said upstream end toward said downstream end and an inner wall element comprising a main body member, a plurality of heat removal members on said main body member extending from said main body moving towards said outer wall, and at least one surface, the surface, in use, facing said downstream end relative to the general direction of fluid flow through the combustor and including a downstream facing surface of at least one of said of said heat removal members, wherein at least said downstream facing surface comprises a thermal barrier coating.
