直升机自适应旋翼驱动系统的研究进展

ADVANCES IN THE DEVELOPMENT OF STRAIN ACTUATORS FOR ADAPTIVE ROTOR

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。

An adaptive rotor consists of composite blades, embedded actuators, embedded sensors and a control system, which may suppress the rotor vibration and improve the mechanical implementation of the upper rotor control system and aerodynamic performance of blades. In this paper, both the principal meaning of the adaptive rotor and strain actuators, one of the key technologies, are reviewed, and the results of research on the smart materials, actuation system and mechanical models for blades are introduced.
