Title:
離陸及び着陸時に回転翼航空機により発せられる騒音を最小化する方法と装置
Document Type and Number:
Japanese Patent JP4406662
Kind Code:
B2
Abstract:
The method includes a preliminary period in which a reference rotorcraft is used that corresponds to a rotorcraft of a particular type, with a series of noise measurements being performed on said rotorcraft (1) in flight using noise sensors (C) disposed on said reference rotorcraft, and with operating domains being determined for the reference rotorcraft in which noise is less than a maximum noise level. Thereafter, the operating point without wind and operating domains with wind are subsequently determined for a rotorcraft of the particular type on the basis of operating domains for the reference rotorcraft.
