A ceramic turbine wheel has been designed as a retrofit for Waspaloy for a military cartridge mode air turbine starter. This results in reduced cost and weight while increasing resistance to temperature, erosion, and corrosion. Techniques used to perform ceramic turbine three-dimensional fast fracture reliability analysis were verified with pin testing of ceramic test rotors and correlated well with burstspeed predictions. Reliability estimates have been made for design and proof conditions, providing guidance for selecting a ceramic supplier and for determining proof test yield. Room temperature whirlpit burst testing is planned to verify the mechanical design and reliability of the wheel.
