Abstract

An aircraft propulsion system (20) includes a combustor (44), an engine oil system (34), a fuel system assembly (36), and a control system (38). The engine oil system (34) includes a fuel-oil heat exchanger (80). The fuel system assembly (36) includes a jet fuel system (86) and a hydrogen fuel system (88). The jet fuel system (86) and the hydrogen fuel system (88) are connected in fluid communication with the combustor (44). The control system (38) is configured to operate the fuel system assembly (36) in one of a first fuel mode to direct a jet fuel from the jet fuel system (86) through the fuel-oil heat exchanger (80) or a second fuel mode to direct a hydrogen fuel from the hydrogen fuel system (88) through the fuel-oil heat exchanger (80).
