Abstract

An individual blade controller designed to attenuate the aeroelastic response of helicopter rotors in forward flight by tailoring the blade root attachment conditions is developed. A feasibility analysis indicates that the open-loop controller which incorporates both passive and active design techniques is energy efficient and may be realized by available adaptive structures.
