Aircraft powerplant with electric powertrain

A powerplant for an aircraft, comprising:

• an engine core including a core compressor section, a core combustor section and a core turbine section;
• a power turbine section comprising a power turbine rotor;
• a core flowpath extending through the core compressor section, the core combustor section, the core turbine section and the power turbine section from an inlet into the core flowpath to an exhaust from the core flowpath;
• an electric generator comprising a generator rotor, the generator rotor mechanically coupled to the power turbine rotor;
• an electric motor electrically coupled to the electric generator, the electric motor comprising a motor rotor, and the engine core axially overlapping the electric generator and the electric motor;
• and
• a propulsor rotor rotatable about an axis and mechanically coupled to the motor rotor, wherein
• the engine core is located to a side of and axially overlaps at least one of the electric generator or the electric motor.
