Abstract

A powerplant (20) is provided for an aircraft. This aircraft powerplant (20) includes a compressor section (40), a fuel-air heat exchanger (86), a recuperator (88), a combustor section (41) comprising a combustor (68), a turbine section (42), a flowpath (50) and a fuel delivery system (28). The flowpath (50) extends from an airflow inlet (64) into the flowpath (50), through the compressor section (40), the fuel-air heat exchanger (86), the recuperator (88), the combustor section (41) and the turbine section (42), to a combustion products exhaust (66) from the flowpath (50). The fuel delivery system (28) includes a fuel source (74), a fuel circuit (76) and a fuel injector (72). The fuel circuit (76) fluidly couples the fuel source (74) to the fuel injector (72) and extends through the fuel-air heat exchanger (86). The fuel injector (72) is configured to introduce fuel into the flowpath (50) for combustion within the combustor (68).
