Claim 15:
16. A method for using the aircraft propulsion system of claim 1 in an aircraft, the method comprising:
running the gas turbine engine to draw in air, compress the air in a compressor section, mix the air with fuel, combust the mixed air and fuel forming combustion products, expand the combustion products in a turbine section to drive the compressor section, expel the combustion products to produce the thrust component to propel flight of the aircraft;
bleeding a bleed flow of compressed air from the gas turbine engine;
passing the bleed flow along the bleed flowpath; and
the bleed flow driving the turbine to drive the propulsion fan to provide said propulsive thrust component and help propel the flight of the aircraft.
