Abstract: An unmanned aerial vehicle comprises a central body; at least one rotor motor configured to drive at least one propeller to rotate, rotation of the at least one propeller generating thrust and causing the unmanned aerial vehicle to fly; and an integrated micro hybrid generator system configured to provide power to the at least one rotor motor. The integrated micro hybrid generator system includes an engine configured to generate mechanical energy, and a generator motor directly coupled to the engine and configured to generate AC power using the mechanical energy generated by the engine.
