Summary

Ceramic combustor liners require no film cooling on the hot-side and minimal backside cooling, due to their high temperature capability. the hotter combustor walls lead to minimal “wall quenching” and better carbon monoxide (CO) oxidation because less cooling is applied. A ceramic combustor can was designed for the ST5+ microturbine engine to improve the engine performance and emissions. the can was designed with special attention to attachment methods that minimize thermal stresses due to the large difference in thermal expansion coefficients between metallic and ceramic materials. Detailed thermal and stress analyses were performed to guide design decisions that lead to optimal component reliability and manufacturability. This paper gives a detailed account of the design and analysis associated with the ceramic combustor can.
