NASA Initiative on Ammonia-based Jet Fuel
Full Story at https://engineering.purdue.edu/ME/News/2022/purdue-researchers-part-of-nasa-initiative-to-explore-ammoniabased-jet-fuel. Purdue researchers Terrence Meyer and Guillermo Paniagua are part of a $10 million five-year project selected by NASA's University Leadership Initiative. Led by the University of Central Florida, the project will explore using liquid ammonia as a potential carbon-free jet fuel. Upon combustion, liquid ammonia produces harmless carbon-free emissions, while still providing enough power to keep the aircraft aloft. It also provides cooling for the engines, while not requiring the special handling of cryogenic fuels. Meyer will be responsible for experimental validation of NH3 combustion at engine representative conditions, while Paniagua will be responsible for the development of supercritical CO2 turbomachinery and heat exchangers, and overall engine modelling.
Other partners include Georgia Tech, GE, Boeing, ANSYS, Southwest Research Institute, and the Greater Orlando Aviation Authority.
