| Abstract: |
| With the rapid development of the new material and technology, the Electromechanical Actuator(EMA) has been successfully applied in the design of fly-by-wire aircraft, advanced space vehicle and thrust vector control systems.This paper introduces researches and applications of the High-power EMA in the world.According to the study, the EMA technology has been applied widely in foreign countries, and began to contribute to thrust vector control of Aerospace in China.We can predict that the EMA will take the place of Hydraulic Servo Mechanism in the future. |
