直升机自适应旋翼由复合材料桨叶、埋入式驱动和传感元件以及控制系统组成，它能够有效地抑制桨叶的振动、改善旋翼的操纵系统和空气动力特性。对自适应旋翼的基本含义和关键技术之一——驱动器进行了评述，并从旋翼驱动材料、驱动系统和力学模型等方面介绍了当前的研究成果。 Helicopter adaptive rotor consists of composite blades, embedded drive and sensor elements and control system, which can effectively inhibit blade vibration and improve the rotor control system and aerodynamic characteristics. The basic meaning of the adaptive rotor and one of the key technologies - the actuator was reviewed. The current research results were introduced from the aspects of rotor driven materials, driving system and mechanical model.
