Evidence suggesting that noise of full-scale helicopter rotors results mainly from unsteady flow; sound-pressure data and spectra for test conditions where gear train, engine and other propulsion system noises are minimized; tip speed (100 to 900 ft/sec) and disk loading affect radiated noise level.
