Add to ORKGThe effects of compressibility arising from high-tip-speed operation on the flapping, thrust, and power of a helicopter rotor in forward speed are investigated for a particular set of airfoil characteristics. Tip-speed ratios ranging from 0.2 to 0.5 were covered at several tip-speed values
