ABSTRACT:
A blade cover cooling apparatus comprises a blade cover top plate, comprising a plurality of upper ribs, a blade cover bottom plate, comprising a plurality of lower ribs. The blade cover top plate is disposed over the blade cover bottom plate. The upper ribs are disposed at a first angle and the lower ribs are disposed at a second angle with respect to the blade circumferential reference line, respectively to form a plurality of flow redirection areas. The blade cover bottom plate is disposed to pass a coolant from the turbine blade to the blade cover top plate. A fabrication method aligns the blade cover top plate and the blade cover bottom plate to form the plurality of flow redirection areas.
