1. A ceramic matrix composite (CMC) component comprising:
a base having a radial outer surface and a radial inner surface inward surface, the base comprising a plurality of ceramic fiber plies and a ceramic matrix, the radial outer surface having a convex shape,
at least one cooling cavity within the base that extends from the outer radial surface of the base into an interior region of the base, the at least one cooling cavity having a cavity opening at the outer radial surface of the base, and the at least one cooling cavity being defined by cavity side walls and a cavity bottom wall, and
a cover plate positioned within the at least one cooling cavity to cover the cavity opening, wherein the cover plate is angled to vary the depth of the cooling cavity between the cover plate and the cavity bottom wall so that the depth varies from a cavity region of greater depth to a cavity region of lesser depth.
