Abstract
A cryogenic fueled aircraft propulsion system includes a core engine where fuel is mixed with compressed air and ignited to generate a high energy exhaust gas flow, a fuel system that is configured to supply the fuel to the core engine, a cryogenic fuel tank for storing fuel cryogenically in a liquid phase, a gas collection system where boil off gas from the fuel system is collected, a fuel cell system where a flow of collected boil off gas is utilized to generate electric power, and an electrical coupling where electric power generated by the fuel cell is communicated to location outside of the aircraft.
