Abstract
A method and to a device for managing energy of a hybrid power plant of a multi-rotor aircraft during a flight. The hybrid power plant comprises a thermal engine, an electricity generator, and a plurality of electric motors, together with a plurality of electrical energy storage devices. The aircraft has a plurality of rotors driven in rotation by respective electric motors. The flight of the aircraft comprises a takeoff stage, a cruising stage, and a landing stage, the takeoff stage and the landing stage being performed solely while consuming electrical energy. The method enables an electrification ratio RElec of the flight to be calculated as a function of the amounts of electrical and thermal energy that are consumed during the takeoff, landing, and cruising stages, thereby limiting the use of the thermal engine to the least possible amount during the cruising stage, and consequently reducing the associated nuisance.
