Novel Ceramic Turbine Rotor Concept.

Abstract

A novel design concept for a ceramic turbine rotor has been studied in detail for a non-man-rated, limited-life gas turbine engine application. The feature of the design involves keeping the rotating ceramic components in a compression state at all turbine operating conditions. An air-cooled composite material containment hoop is utilized at the outer diameter of ceramic air-cooled fins which support ceramic turbine blades in compression against a radially compliant wheel. The design study of this Compression Structured Ceramic Turbine Rotor included detailed material, heat transfer, and 3-D stress analyses. The study effort also looked at the operational limits of the design and a performance and economic analysis comparison to a baseline metal design. Conclusions and recommendations for future development are also presented in this report. (Author)
