本论文主要阐述了液压系统的原理,主要部件组成,功用，以及维护与修理。液压系统是指飞机
上以油液为工作介质，靠油压驱动执行机构完成特定操纵动作的整套装置。液压系统由液压油箱、油箱增压系统、液压泵、地面勤务系统等组成。由于飞机液压系统的工作情况直接与飞行安全密切相关。故现代飞机上大多装有两套(或多套)相互独立的液压系统。单位功率重量小、系统传输效率高、安装简便灵活、惯性小、动态响应快、控制速度范围宽、油液本身有润滑作用、运动机件不易磨损张英森是其优点；缺点zigbee自组网
为圈套器油液容易渗漏、不耐燃烧、操纵信号不易综合。与其他机械的液压系统相比，飞机液压系统的特点是动作速度快、工作温度和工作压力高。本论文主要以波音737为例分析飞机液压系统。

Abstract: This paper describes the principle of the hydraulic system, major components, fu
nction, and maintenance and repair. Aircraft hydraulic system is to oil as the working medium, by the hydraulic actuator to complete a specific set of device control action. Hydraulic system by hydraulic tank, fuel tank pressurization system, hydraulic pump, ground service system components. Since the work of the aircraft hydraulic system directly related to flight safety. Therefore, most modern aircraft equipped with two (or sets) of independent hydraulic system. The weight of a small unit power, the system transmission efficiency, ease of installation flexibility, inertia is small, fast dynamic response, wide speed control, lubrication oil itself, moving parts, easy to wear its advantages; disadvantage of easy oil leakage, impatience burning, easy to manipulate the signal integrated. Hydraulic and other mechanical systems, aircraft hydraulic system is characterized by a movement speed, high temperature and pressure. In this thesis, an example of Boeing 737 aircraft hydraulic system.
