1. A power unit comprising:
an engine comprising a driving shaft;
a power generator provided on the driving shaft and configured to supply electric energy to a flight vehicle; and
a thrust generator provided on an outer side of the power generator and configured to provide a propulsion force to the flight vehicle,
wherein when a temperature of the power generator is greater than or equal to a first temperature, the power generator and the thrust generator are decoupled from each other, and the power generator is driven by an output of the engine and supplies the electric energy to the flight vehicle, and when the temperature of the power generator is less than the first temperature, the power generator and the thrust generator are coupled to each other, and the thrust generator is driven by the output of the engine and provides the propulsion force to the flight vehicle.
