Abstract:The design of the adaptive rotor is different from that of the conventional passive rotor. By actively changing the rotor parameters, the rotor lift-to-drag ratio can be optimized to get adaptive to the flight environment and flight condition, so as to reduce the power consumption of the rotor and improve the flight performance of the helicopter. This paper summarizes national and international research progress in using adaptive rotors to improve the performance of the rotor, including the variable speed rotor, variable diameter rotor, individual blade pitch control rotor, active twist rotor, morphing blade airfoil, etc. The research progress and prospects in performance improvement by adaptive rotors are also summarized. © 2018, Press of Chinese Journal of Aeronautics.
