2 Aircrafts Structure Unit 3 Aircrafts System,Aircrafts System,1.Hydraulic System 液压系统Among the units commonly operated by hydraulic systems are landing gear,wing flaps,speed and wheel brakes,fixed-wing and rotary-wing folding mechanisms and flight control surfaces.,There are three types of hydraulic fluids currently being used in civil aircraft：,The phosphate ester base fluids are used in high performance piston engines and turboprop aircraft.,reservoir 液压油箱filter 过滤器accumulator 蓄压器check valve 单向阀hand pump 手动泵power-driven pump 动力驱动泵pressure regulator 压力调节器pressure gage

meet the demands of the engine.A well designed fuel system ensures positive and reliable fuel flow throughout all phases of flight,which include changes in attitude,violent maneuvers and sudden acceleration and deceleration.,The indicators such as fuel pressure gages,warning signals and tank quantity gages are provided to give continuous indications of how the system is functioning.Gasoline（汽油）and kerosene（煤油）are the two most widely used aviation fuels（航空燃料）.,Two types of jet turbine engine（涡轮喷气发动机）fuel in common use today are:kerosene grade turbine fuel 煤油涡轮燃料 a blend of gasoline and kerosene fractions 汽煤混合馏分燃料,The integral fuel tank（整体油箱）in a jet airliner has：fuel tank 油箱 main tank 主油箱 reserve tank/auxiliary tank 储备油箱 center tank 中央油箱 trim tank 重心调整油箱 vent surge tank 通风(防震动)油箱 horizontal stabilizer tank(on some aircraft),Two types of fuel feed system are used to supply the fuel to the engines.They are:gravity feed system 重力式供给系统 pressure feed system 压力式供给系统,The gravity feed system is the simplest type which is still in use on many low-powered airplane,while the pressure feed system is much complex in construction and operation.,manifold

controllable,it means that the aircraft responds easily and promptly to the movement of the controls.Moving the control surfaces on an aircraft changes the airflow over the aircrafts surface.,The flight control surfaces are hinged or movable airfoils designed to change the attitude of the aircraft during flight.These surfaces may be divided into three groups,usually referred to as the primary group and auxiliary group.,The primary group includes the ailerons,elevators and rudder.They are used for moving the aircraft about its three axes.The ailerons and elevators are generally operated from the cockpit by a control stick on single-engine aircraft and by a wheel and yoke assembly on multi-engine aircraft.The rudder is operated by foot pedals on all types of aircraft.,The auxiliary group includes spoilers,speed brakes,slats and flaps.The auxiliary group may be divided into two sub-groups:the lift augmenting devices and the lift decreasing devices.The lift augmenting devices are trailing edge flaps and leading edge slats.The lift decreasing devices are speed brakes and spoilers.,The flight control systems may be divided into two major parts:the primary control systems and the auxiliary control systems.The primary control systems are used to control the primary group of control surfaces,while the auxiliary control systems are used to control the auxiliary groups of control surfaces.,(1)control surface 操纵面 primary control surface 主操纵面 aileron 副翼 rudder 方向舵 elevator 升降舵 auxiliary control surface 辅助操纵面 trim 调整片 flap 襟翼 speed brake 减速板 horizontal stabilizer 水平安定面,(2)primary

the aircraft about each of the three axes.(1)vertical axis/yaw axis 垂直轴 yaw 偏航 The nose of the aircraft swings from side to side.(2)lateral axis/pitch axis 横轴 pitch 俯仰 The nose of the aircraft moves up and down.(3)longitudinal axis/roll axis 纵轴 roll 滚转 The wings of the aircraft move up and down.,4.Landing Gear System 起落架系统,The landing gear of a fixed-wing aircraft consists of main and auxiliary units,either of which may or may not be retractable.The auxiliary landing gear consists of tail or nose wheel installations,outboard pontoons（浮筒）,skids（刹车）,etc.,with necessary cowling and reinforcement.,The main landing gear forms the principle support of the aircraft on land or water and may include any combination of wheels,floats,skids,shock-absorbing equipment,brakes,retracting mechanism with controls and warning devices,cowling,fairing（整流罩）and structural members necessary to attach any of the foregoing to the primary structure.,inboard retracting main gear 向内收起式主起落架 forward

is designed to perform any or all of the following functions:supply ventilation air,supply heated air and supply cooling air.,
