An endwall assembly for an airfoil of a gas turbine engine includes a first fiber layer, a second fiber layer forming a gas path surface, and a contoured insert disposed between the first and second fiber layers, wherein the second fiber layer conforms to a contoured surface of the contoured insert such that the contoured surface defines a geometry of the gas path surface.

The disclosure describes methods and devices for directing/controlling cooling air flow for cooling CMC components. A cover plate is positioned within a cooling cavity in the CMC component wherein the cover plate is angled to vary the depth of the cooling cavity between the cover plate and a bottom wall of the cavity. The angled cooling plate can be used to vary the flux of cooling air within the cooling cavity and thereby achieve a desired cooling performance within the cooling cavity.
