To provide basic data on rotor blade motion, photographic records of behavior of blade in flight were obtained with conventional single rotor helicopter; results of measurements of flapping motion, in-plane motion, and blade distortions presented for selected conditions of flight at tip speed ratios ranging from 0.12 to 0.25.
