The present invention relates to a device () for controlling an electric aircraft-propelling assembly, said propelling assembly comprising a propeller () and at least one electric motor () that is powered by an electric supply voltage and that delivers a torque and a rotation speed to drive the propeller (). The control device () comprises at least a unit () for measuring an electric supply voltage, and a control unit () suitable for making a signal delivered to the electric motor vary as a function of said electric supply voltage, with a view to making the rotation speed of the propeller vary.

Device for controlling a least one electric motor for an aircraft-propelling assembly

A hybrid propulsion system for a vertical take-off and landing aircraft comprising at least one combustion engine driving an electricity generator, at least one electrical energy storage assembly associated with each electricity generator and defining, with each electricity generator, an energy branch, a plurality of electric motors actuating a same plurality of rotors providing together the propulsion and/or the lift of the aircraft, and an electrical power and distribution unit supplying power to the plurality of electric motors from the electricity generator and/or from the electrical energy storage assembly according to a pre-established flight phase, the system including at least two energy branches having an asymmetric configuration and each supplying power selectively, by means of the electrical power and distribution unit, all or part of the plurality of electric motors, and in that the electricity generators of the combustion engines have between them a power ratio comprised between.
