Title:
TURBINE ENGINE MULTI-WALLED STRUCTURE WITH INTERNAL COOLING ELEMENT(S)
Document Type and Number:
WIPO Patent Application WO/2015/122950
Kind Code:
A3
Abstract:
A structure is provided for a turbine engine. The structure includes a shell with a first surface, and a heat shield with a textured second surface and a textured third surface. The texture of a portion of the second surface is different than the texture of a portion of the third surface. The first surface and the second surface define a first cooling cavity between the shell and the heat shield. The first surface and the third surface define a second cooling cavity between the shell and the heat shield.
