1. A propulsion system for an aircraft, comprising:
a chassis,
a propeller mounted to be able to move in rotation on the chassis about an axis of rotation,
a main gear as one with the propeller and coaxial with the axis of rotation,
an electric generator,
at least one linear electric motor electrically powered by the electric generator and having a fixed element fastened to the chassis and a slider configured to move in translation along the fixed element in a direction of movement,
for each linear electric motor, a secondary gear meshing with the main gear and mounted to be able to move in rotation on the chassis about an axis of rotation perpendicular to the propeller axis of rotation, and
for each linear electric motor, a rod with a first end and a second end, of which the first end is mounted articulated at a first articulation on the slider of the corresponding linear electric motor, and of which the second end is mounted articulated at a second articulation on the corresponding secondary gear at an articulation offset with respect to the axis of rotation of the secondary gear associated with the linear electric motor.
