ABSTRACT:
A planar top plate (32) has film cooling slots (34) therein. A rigid honeycomb structure (38) sealingly joins this top plate with bottom plate (36). Cooling air distributed by openings (50) impinges on the top plate and passes through metering openings (48) to the slots. A flat wall surface with reduced aerodynamic losses is maintained and the uniform support of the top plate avoids local distortion which would crack any heat resistant coating applied thereto.
