1. A hybrid propulsion system comprising:
a heat engine configured to drive a heat engine shaft;
an electric motor configured to drive an electric motor shaft; and
a transmission system connected to receive rotational input power from each of the heat engine shaft and the electric motor shaft, wherein the transmission system is configured to convert the rotational input power to output power;
wherein the heat engine shaft and the electric motor shaft are concentric with a shaft for rotation of a turbocharger component of the heat engine.
