Abstract

A cover plate (140) for enclosing a cooling cavity (130) of a ceramic matrix composite (CMC) component (100) of a turbine engine may include a base plate (141) dimensioned to cover an open cooling cavity (130) of the CMC component (100). The base plate (141) has a first side facing the cooling cavity (130) and at least one feature plate (145) is attached to the first side of the base plate (141). At least one heat transfer augmentation feature (145) is formed on the at least one feature plate (142) and extends into the cooling cavity (130), wherein the at least one heat transfer augmentation feature (145) is configured to cause turbulence in a cooling air flow within the cooling cavity (130). Thus, rather than forming complex heat transfer augmentation features (145) on the cooling cavity (130) of the CMC component (100) itself, such features can be easily provided using metal plate or sheet material or separately-formed CMC elements on the cover plate (141).
