Abstract

Abstract:

The proximity of tiltrotor aircraft blade tips to the fuselage causes a serious near-field aeroacoustics problem. Theoretical research shows that Higher Harmonic Control （HHC） input can adjust the load distribution of the rotor disc， thereby reducing the aeroacoustics radiation on the fuselage surface. In this paper， the suppression effect of HHC on near-field aeroacoustics in tiltrotor aircraft is verified experimentally. An HHC servo control system for model tiltrotor aircraft and a scaled fuselage model for tiltrotor aircraft are developed. An HHC active control test platform for near-field aeroacoustics in tiltrotor aircraft is further built in the anechoic chamber environment， and noise active control tests are carried out in helicopter mode. The active control effects of HHC on near-field aeroacoustics in tiltrotor aircraft are verified. The test results demonstrate that the 2 Ω HHC control input yields the best noise reduction performance. In helicopter mode， the near-field aeroacoustics at the observation point on the top of the fuselage can be reduced by up to 4.5 dB.
