ABSTRACT:
An array of skewed cooling air conduits are embedded within a ceramic turbine blade for cooling an upper blade surface by producing a cool air film thereon, and by removing heat through conduction. The conduits provide a large bonding surface area in the ceramic, and are recessed to prevent clogging by the ceramic and to prevent direct contact with the hot gas stream at the upper blade surface.
