The purpose of this study was to investigate the aerodynamic behavior of a helicopter rotor operating in the low-speed flight regime, particularly in the nap-of-the-earth (NOE) evasive mode. The effort consisted of reducing and analyzing existing AH-1G flight test response data acquired for simulated NOE flight under Contract DAAJ02-73-C-0105. Specific areas of interest analyzed in this study include blade/vortex interaction at 50 knots and angle-of-attack data derived from hot-wire measurements taken in hover.
