摘　　要：现代飞机舵面操纵系统与动力收放系统几乎都是液压驱动的。随着飞机特别是军用飞机的发展 ,对机载液压系统提出了更高的要求。文章对飞机特别是军用飞机液压系统的主要发展趋势进行了综述 ,并对国内外的飞机液压系统的研究工作进行了一定的介绍。指出 :质量轻、体积小、高压化、大功率、变压力、智能化、集成化、余度技术等是未来飞机液压系统的主要发展趋势 。High density of driving power,fast response,high rigidity and high\|precision are the advantages of hydraulic servo system,so it is widely used in aerospace.All of flight actuator and transmitting systems of todays aircrafts are nearly driven by hydraulic systems.With the development of aircraft,especially of military aircraft,more demands are proposed to aircraft hydraulic system.In this paper,main developmental trend of airborne hydraulic system,especially for military aircraft,is summarized,and some research works on aircraft hydraulic systems in domestic and overseas are introduced.Light weight,small size,high\|pressure,high power,variable pressure,intellectualization,integration,redundancy techniquue,and so on are the main trend of development of future aircraft hydraulic system.Especially,high pressure,variable pressure hydraulic intelligent pump source system is very important for the development of future aircraft.
