1. An apparatus for generating electrical power in an aerial vehicle having an engine, a propeller, and a drive shaft coupled between the engine and the propeller, the apparatus comprising:
an alternator disk structure (ADS) disposed between the engine and the propeller, the ADS including an inner region and an outer region,
the inner region of the ADS being rotationally fixed relative to an engine block of the engine and including a stator, the stator having windings,
the outer region of the ADS being free to rotate relative to the inner region, the outer region coupled to the drive shaft and including a rotor,
wherein the rotor of the outer region is constructed and arranged to spin relative to the stator of the inner region in response to rotation of the drive shaft by the engine, thereby inducing electrical current in the windings of the stator, and
wherein the outer region is part of a starter ring gear support (SRGS) concentric with the drive shaft and coupled to an electric starter, the SRGS constructed and arranged to rotate the drive shaft for starting the engine.
