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.
