- This research aims to study the acoustic noise prediction and reduction of helicopter ducted tail rotor. A thin-body BEM/FW-H method is developed to accurately predict the noise in this paper. It is a hybrid method combining computational aero acoustics with Boundary Element Method (BEM) and can be used efficiently to predict the propagation of sound wave in the duct. And two main geometry parameters are modified to investigate the noise reduction of ducted tail rotor by using the numerical prediction method. The acoustic performance of different modification tasks is discussed. These results verify the efficiency of design parameters modification to reduce acoustic noise of ducted tail rotor.
