Claim 0:
1. A propeller propulsion unit, comprising at least one kinematic system comprising:
a heat engine consuming fuel;
a main shaft rotated at an output of the heat engine;
an electrical energy generator configured to generate electrical energy from the rotation of the main shaft;
an electric motor configured to generate a rotary movement as output from the electrical energy generated by the electrical energy generator;
a coupling element comprising a toothed gear and a shaft; and
a propeller rotated by the coupling element,
wherein the at least one kinematic system selectively assumes one of a first configuration or a second configuration at a given time,
wherein the toothed gear of the coupling element is movable through translational movement between a position in which the toothed gear is coupled to a toothed gear attached to the main shaft of the heat engine and a position in which the toothed gear of the coupling element is coupled to a toothed gear of the electric motor,
wherein, in the first configuration, the coupling element is coupled to and driven by a rotational output of the electric motor,
wherein, in the second configuration, the coupling element is coupled to and driven by a rotation of the main shaft.
