DFVLR/FAA (Deutsche Forschungs-und Versuchsanstalt fuer Luft und Raumfahrt/Federal Aviation Administration) Propeller Noise Tests in the German-Dutch Wind Tunnel DNW. Appendix IV. The Effect of Propeller Disc-Plane Attitude (Propeller 1: Thickness 6.4%, Round Tip-Shape),

Abstract

In this Appendix the test results on the effect of propeller disc plane attitude (Propeller 1: Thickness 6.4%, round 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.
