Description: Report presenting an analysis of the overall sound-pressure levels and frequency spectra of the noise emitted from a full-scale, 7.2-foot-diameter, 3500-rpm, three-blade, supersonic propeller mounted on a turbine-powered airplane under static conditions at stations about the propeller at a 100-foot radius. Variations in power produced the variations in overall sound-pressure levels predicted by theory.
