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 ...
A full-scale wind tunnel test program was begun to explore the potential of an individual blade control (IBC) system to reduce noise and vibration, and to improve rotor performance of a UH-60 (Black Hawk) helicopter. The first phase of this testing was performed using the U.S. Army/NASA Large Rotor Test Apparatus (LRTA) to operate a full-scale UH-60A rotor in the NASA Ames Research Center 80- by 120-Foot Wind Tunnel. The ...
