Zusammenfassung:
A detailed experimental acoustic investigation was carried out in the German/Dutch low speed wind tunnel DNW on a 6-bladed 1:5 scale model propeller. The propeller near and far-field noise was measured with axially traversing in-flow microphones. Included were tests under non-zero angle of attack and sidesl ip angle in order to obtain also data for a noise prediction method for propeller installation effects. In this paper far-field noise data are compared with theoretical data to show the capability of the prediction scheme, to estimate free-field and installed characteristics in the far-field. The intention is to compare the far-field noise changes with angle of incidence.
