Abstract

The scattering of noise generated by helicopter rotors has been recognized as having a significant influence on both the noise spectra and the noise directivity. This paper presents the research by DLR within the collaborative effort in the GARTEUR Action Group HC/AG-24. Shielding experiments were conducted in DLR Acoustic Wind tunnel in Braunschweig (AWB) using point and rotor sources. For the numerical simulation of the various test cases, DLR boundary element method was applied. The acoustic scattering predictions are compared to both test data and analytic solution
