Claim 5:
6. An electric propulsion architecture for a multi-rotor vertical take-off and landing aircraft, comprising
N electric generators, N being an integer greater than or equal to 2, and
N pairs of rotors,
each rotor comprising a first electric motor and a second electric motor, the first electric motor being configured to operate in an active mode and the second electric motor being configured to be in a standby mode and being adapted to operate in an active mode in the event of a breakdown of an electric motor of a rotor, of a rotor, or of an electric generator, and
for each rotor, a propeller coupled to the first and second electric motors so that during operation the first electric motor drives the propeller,
wherein for each pair of rotors, a first of the N electric generators supplies the first electric motors of the rotors of one pair of rotors, and a second of the N electric generators supplies the second electric motors of the rotors of one pair of rotors,
and wherein the rotors of the pairs of rotors form counter-rotors; and for each counter-rotor, the first and second electric motors of the rotors of each counter-rotor are each supplied by one of the N electric generators so that the N electric generators supply the first and second electric motors of the rotors of each counter-rotor.
