Method and device for minimizing the noise lift-off and during the landing of a rotorcraft

摘要

- method and device for minimizing the noise during takeoff and landing of a rotorcraft - according to the process, in a preliminary step, one uses a reference rotorcraft corresponding to a rotorcraft of a particular type, a series of measurements of the noise on the rotorcraft (1), in flight, on the basis of acoustic sensors (c) arranged on the said reference rotorcraft, it determines the fields of operation of the reference rotorcraft, in which the noise is less than a maximum level of noise. Then, in a subsequent step, it determines the point of operation without wind and the fields of operation with wind of a rotorcraft of the particular type from the fields of operation of the reference rotorcraft.
