Some Peculiarities of Helicopter Main Rotor Aeroacoustic for Far-Field Observer

Some Peculiarities of Helicopter Main Rotor Aeroacoustic for Far-Field Observer

Mathematical models for helicopter rotor acoustics are usually based on the Ffowcs Williams–Hawkings (FW–H) equation. The level of rotor noise is determined by geometry (thickness noise) of a flying vehicle and distributed blade loading (loading noise). Initially, the FW-H equation was obtained from...
