Abstract:

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.

Key words: rotor, actuators, smart materials, adaptive
