Abstract
The GARTEUR AG24 shielding experiments were conducted in DLR’s Acoustic Wind tunnel in Braunschweig (AWB), where the scattering for generic configurations was studied using two point sources and one rotor source. Comparisons of the experimental results with the numerical simulations have been carried out. The numerical results are obtained using DLR’s fast multipole boundary element method. The comparison of the scattering of the GARTEUR helicopter model shows a very good agreement in terms of amplitude and phase. In the framework of AG24, a unique noise scattering database was establishedthrough dedicated wind tunnel tests, enabling the assessment, and further development, of current noise scattering predictiontools capabilities.
