DUAL CYCLE INTERCOOLED HYDROGEN ENGINE ARCHITECTURE

A gas turbine engine (100) includes a primary gas path (1060 having, in fluid series communication: an air inlet (112), a compressor section (104) fluidly connected to the air inlet, a combustor section (108) fluidly connected to an outlet of the compressor, and a turbine section (116) fluidly connected to an outlet of the combustor section. The gas turbine engine includes a heat exchanger (122) having a gas conduit (126) fluidly connected to the primary gas path, and a fluid conduit (128) in fluid isolation from, and in thermal communication with, the gas conduit. A hydrogen expansion turbine (134) receives hydrogen from the gas conduit of the heat exchanger.
