Bending-moment distributions were measured on a model helicopter rotor blade under hovering and simulated forward-flight conditions. Curves of maximum-bending-moment distribution are presented for all test conditions. Theoretical calculations have been carried out at advance ratios of 0.22 and 0.47 for the hinged- and fixed-at-root conditions respectively.
