This works well for locomotives, because mechanical transmission of power from the engine to the drive axles would be too complex and troublesome. But the series-hybrid configuration suffers the disadvantage in that overall efficiency of this arrangement is the product of the efficiencies of the generator/alternator and drive motors. For airplanes, it may be better to use a parallel-hybrid configuration whereby the engine drives the propeller directly, but with an electric machine on the driveline. Said electric machine would function as a motor to assist takeoff, or as a generator to provide for the aircraft’s electric power needs.
