A current NASA-sponsored contract will develop attachment technology for hybrid turbine rotors having dovetailed ceramic ceramic blades and a wrought metal disk. The approach and sequence of activities are described in detail. The program scope includes design, fabrication, and spin testing of hot-pressed silicon nitride blades for operation at rotor inlet temperatures of 2192 F (1200 C) or greater.
