DFVLR/FAA (Deutsche Forschungs-und Versuchsanstalt fuer Luft und Raumfahrt/Federal Aviation Administration) Propeller Noise Tests in the German-Dutch Wind Tunnel DNW. Appendix V. The Effect of Propeller Disc-Plane Attitude (Propeller 2: Thickness 8.5%, Square Tip-Shape),

Abstract

In this Appendix the test results on the effect of propeller disc plane attitude (Propeller 2: Thickness 8.5%, square tip shape) are documented in terms of pressure time histories, narrow band spectra and unweighted as well as A weighted overall sound pressure levels, together with supplementary information necessary for further data interpretation.
