DFVLR/FAA (Deutsche Forschungs-und Versuchsanstalt fuer Luft und Raumfahrt/Federal Aviation Administration) Propeller Noise Tests in the German-Dutch Wind Tunnel DNW. Appendix III. The Effect of Flow Temperature),

Abstract

In this Appendix the test results on the effect of flow temperature 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.
