Williams International has been actively investigating the use of ceramic materials in gas turbine engines for over 10 years. Ceramic component applications include both static and dynamic components such as combustors and turbine rotors. Component stresses, material properties, and cost, dictate attachment strategies. Non-metallic turbines with metal-to-non-metallic attachment schemes have been successfully demonstrated. This paper reviews a progression of attachment strategies that eventually led to a successful test of a non-metallic turbine in a gas turbine engine.
