Project Description

Hydrogen-fueled detonation system is ideal for enhancing thermal efficiency and eliminating C02 emissions for clean aviation and power generation. The project objectives are to: (1) demonstrate the superior efficiency of the detonation combustor and turbine; (2) demonstrate this is a cleaner technology while resolving critical technical challenges in the combustor-turbine. The combustor-turbine environment is exposed to temperatures above 2300K while undergoing extreme temperature excursions. The compatibility of current structural alloys is unknown. The highly unsteady and shock-laden combustor exhaust flow requires unsteady work extraction and robust designs. Novel refractory multi-principal element alloys will be evaluated experimentally in the Purdue turbine test rig, representing a stark departure from traditional design practices. This project will leverage currently-funded programs at Purdue by the DoE, AFOSR, and NSF.
