摘　　要：随着飞机的舵面控制系统的要求进一步提高,功率电传作动技术是多电飞机区别于传统飞机的关键技术之一,功率电传作动系统的应用将取消飞机上原有的分散液压源和气压源,而采用电动静液作动器作为传动部件。本文阐述了航空电动静液作动器的技术发展概况,介绍了航空电动静液作动器的系统组成,分析比较了EHA在三种不同原理及特点,总结了EHA在飞机应用中的优势。With the further improvement of the requirements of the aircraft's control system,power transmission technology is one of the key technologies for multi-electric aircraft.The application of power transmission system will eliminate the original distributed hydraulic source and air pressure source on the aircraft,Electro-Hydrostatic Actuator will be used as the transmission component. This paper describes the technical development of Electro-Hydrostatic Actuator, introduces the system of Electro-Hydrostatic Actuator,and analyzes the characteristics of three different working principles,summarizes the advantages of EHA in aircraft applications.
