U S Army Aviation Laboratories (USAAVLABS) instrumented and flight-tested CH-47A helicopter to measure steady and dynamic loads on rotors, controls, and airframe; test conditions included high blade loadings and range of flight speeds from hovering through transition and up to rotor stall-limited speed; measurements of blade airload pressures and resulting blade bending, rotor hub motions, rotor shaft loads, control loads, and fuselage response were obtained using automatic analog-to-digital data processing techniques; suggested approach to reducing rotor blade airloads data to synthesized airfoil section data is presented.
