  • Electric propulsion architecture for a multi-rotor vertical take-off and landing aircraft and method for controlling such an architecture
    Patent number: 11905024
    Abstract: An electric propulsion architecture for a multi-rotor vertical take-off and landing aircraft includes four electric generators; and four pairs of rotors. For each rotor, a first electric motor is configured to operate in an active mode, and a second electric motor is configured to be in a standby mode and being able to operate in an active mode in a breakdown situation. A propeller is coupled to the electric motors, wherein, for each pair of rotors, one of the electric generators powers the first electric motors, and another of the electric generators powers the second electric motors. The rotors form counter-rotors and for each counter-rotor, the electric motors are each powered by one of the four electric generators so that the four electric generators power the electric motors of the rotors of each counter-rotor.
