Abstract
A gas turbine engine assembly includes an engine core and an electric machine. The engine core includes a first rotating structure, a second rotating structure, a combustor and a flowpath. The first rotating structure includes a first structure turbine rotor. The second rotating structure includes a second structure compressor rotor, a second structure turbine rotor and a second structure shaft connecting the second structure compressor rotor to the second structure turbine rotor. The second structure compressor rotor, the combustor, the second structure turbine rotor and the first structure turbine rotor are arranged sequentially along the flowpath. The electric machine is arranged within the engine core. The electric machine includes an electric machine rotor and an electric machine stator adjacent the electric machine rotor. The electric machine rotor is rotatable with the second rotating structure and located between the second structure compressor rotor and the first structure turbine rotor.
