METHOD FOR OPTIMISING THE NOISE GENERATED IN FLIGHT BY A ROTORCRAFT

摘要

The invention relates to a method for optimizing the noise generated by the driving device (10) of the rotorcraft (1) in flight. The hybrid driving device (10) drives the main rotor (2) of the rotorcraft (1) to rotate and has at least one heat engine (11),A motor (13) and at least one power supply (18) supply power to the motor (13). The process includes determining (120) the power required for the flight phase provided by the hybrid device (10), and (130) LThe required power is translated between the at least one heat engine (11) and the motor (13) according to the target noise level and the required power during the flight phase, and the noise model generated by the at least one heat engine (11) according to one of its parametersThus, the noise generated by the hybrid device (10) is limited.
