摘要
The present invention relates to a method for optimizing the noise generated by a rotorcraft (1) on the ground, said rotorcraft (1) comprising a hybrid power plant (10), at least one rotor (2,3) and an energy source. electric (18). Said method makes it possible to check whether each heat engine (11) of said hybrid power plant (10) is started or stopped, as well as the state of each electric machine (13) of said hybrid power plant (10). Said method also makes it possible to check whether said rotorcraft (1) is on the ground. Then, each heat engine (11) started is controlled to reach an idle speed or until it stops and said electric machine (13) is regulated according to a setpoint of the speed of rotation of a rotor (2) so as to drive each rotor (2,3) while limiting the noise generated by said hybrid power plant (10).
