A ceramic vane turbine nozzle design has completed over 2000 hours of engine endurance testing for production qualification in the Gemini radial-flow turbine manufactured by the TurboMach Division of Solar Turbines Incorporated. The nozzle offers the advantage of substantial erosion and corrosion durability over all-superalloy types. Cost effective production methods and tooling have been demonstrated on a production lot of nozzles and all preproduction tasks including establishment of ceramic vane acceptance criteria have been completed. Further application of ceramics to the Gemini turbine are described and include all static hot-section components, i.e., combustor liner, combustor scroll, nozzle assembly and exhaust scroll. These ceramic components allow temperature up-rating of the Gemini turbine’s power by 50 percent.
