In this Report a method of obtaining the transient solution of the helicopter rotor blade flapping motion is developed and the effective damping of the motion determined for tip speed ratios up to unity and above. When reverse flow over the retreating blade is ignored, it is found that the motion becomes unstable in the region of tip speed ratios of ,~ for… CONTINUE READING
