自适应旋翼性能研究进展

Research progress in performance of adaptive rotor

自适应旋翼不同于常规被动旋翼设计,通过主动改变旋翼参数,优化旋翼升阻比,以适应飞行环境和飞行状态的变化,从而降低旋翼需用功率、提升直升机飞行性能。本文归纳了自适应旋翼在提升旋翼性能方面的国内外研究进展,主要包括:变转速旋翼、变直径旋翼、独立桨距控制旋翼、智能扭转旋翼以及桨叶翼型变体等,并对自适应旋翼提升旋翼性能方面的研究进展进行了总结和展望。

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.
