A full-scale four-bladed UH-60/Wide Chord Blade rotor system was tested in the NASA Ames 40- by 80-Foot Wind Tunnel. A quality data set at forward speeds of 60 to 150 knots were obtained to support future rotor developments and analysis improvements. The rotor performance data were compared with flight test data and CAMRAD II predictions. Wind tunnel comparisons with flight test data show good agreement at all advance ratios tested except above an advance ratio of 0.30. CAMRAD II power calculations show good agreement with full-scale wind tunnel data at advance ratios between 0.20 to 0.35 and poor agreement at advance ratio of 0.15. CAMRAD II propulsive force calculations show fair to good correlation with full-scale wind tunnel data at all advance ratios tested.
