Abstract

Various embodiments may include a drive system for an aircraft comprising: an electrical generator; and an internal combustion engine with a gas expansion turbine. The generator includes a rotor rotating on a rotor shaft. The gas expansion turbine rotates on a turbine shaft. The rotor shaft and the turbine shaft are couplable to transmit torque such that the internal combustion engine can deliver mechanical energy to the generator. A supply air stream impinges at least one component of the generator.
