Abstract

An aircraft propulsion system (20) includes a combustor section (28), an engine oil system (34), and a fuel system (36). The combustor section (28) includes a combustor (44) forming a first portion of a core flow path (68) through the aircraft propulsion system (20). 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) is connected in fluid communication with the combustor (44) and configured to selectively direct a jet fuel to the combustor (44). The hydrogen fuel system (88) is connected in fluid communication with the combustor (44) and configured to selectively direct a hydrogen fuel to the combustor (44). The hydrogen fuel system (88) is further connected in fluid communication with the fuel-oil heat exchanger (80).
