  • Rotorcraft having an electric drive for driving a main and/or tail rotor of the rotorcraft
    Patent number: 12157561
    Abstract: A rotorcraft having an electric drive for driving a main rotor of a rotorcraft, more particularly a helicopter, the electric drive comprising: a coupler for coupling the electric drive to a rotor mast, which can be coupled for conjoint rotation with a drive unit of a helicopter rotor transmission, for coupling for conjoint rotation with the main rotor or tail rotor. A rotorcraft with an electric drive is provided with which the space requirement is reduced, the construction is simplified and the maintenance requirement is reduced. This problem is solved in that the electric drive is designed as an electric ring motor, with the electric ring motor being arranged and attached coaxially with the rotor mast.
