Abstract

Helicopter rotor aerodynamic noise has become an important research topic in helicopter technology with the widespread use of helicopters. This paper outlines the current status of the research on rotor thickness noise, loading noise, high speed impulsive (HSI) noise, blade vortex interaction (BVI) noise, and broadband noise. Domestic and foreign research on numerical calculation methods and experimental methods for rotor noise are reviewed, and the application of trailing-edge flap, higher harmonic control (HHC), individual blade control (IBC) and active twist blade to rotor noise control are also introduced. The latest research progress in helicopter rotor aeroacoustics noise is described, including new progress in the effects of atmosphere, ground and flight trajectory on the rotor aerodynamic noise, and the methods for calculating the acoustic scattering field of helicopter fuselage and maneuvering noise. The main work of the research on aerodynamic noise of the helicopter rotor is concluded and some prospects are also presented.
