Correlation of wind tunnel results of a full-scale four-bladed hingeless rotor system with flight test measurements is presented. The results presented are from a recently completed full-scale rotor test in the NASA Ames 40-by 80-Foot Wind Tunnel and a recently completed flight test of a BO-105 helicopter at the Deutsche Forschungsanstalt fuer Luft-und Raumfahrt e.V. (DLR), Braunschweig, Germany. Rotor hub and blade loads are shown over a range of advance ratios from 0.1 to 0.34 for CT/963;=0.07. Good correlation of measured blade root flap bending moments in the wind tunnel with flight test measurements is shown when the rotor is trimmed to measured flight test hub pitching and rolling moments. Analytical results using the CAMRAD/JA (Comprehensive Analytical Model of Rotorcraft Aerodynamics and Dynamics, Johnson Aeronautics) analysis shows good correlation when the analysis is trimmed to isolated rotor once-per-revolution root flap moments.
