(5) Two control columns provide pitch control of the airplane . each control column extends through the floor into the lower nose compartment. A torque tube connects the control columns together. The control columns allow the pilots to control the airplane about the lateral axis. 两个驾驶杆提供飞机俯仰控制。每个控制杆通过地板沿伸到前舱。一 个扭个管将驾驶杆连在一起。驾驶杆允许驾驶员沿水平轴控制飞机。 (6) Control about the vertical axis is provided by the rudder. Control is provided by a single rudder without tab. The rudder is pedal operated by the captain or the first officer. Pedal movement rotates the forward quadrants, which are cable connected to the aft quadrant. Rotation of the aft quadrant moves a control rod connected to a torque tube. Rotation of the torque tube moves a crank connected to the rudder power control unit linkage. This admits hydraulic fluid to the actuating cylinder, which moves the rudder. 飞机垂直方向上的控制由方向舵提供。通过一个单独的不含调整片的方向舵提供控制。方向舵由机长或副驾驶的脚蹬控制。随着脚蹬的移动，使得前扇形盘转动，前扇形盘由线缆连接到后扇形盘。后扇形盘的转动带动一个连接着一个扭力管的操纵杆。扭力管的转动带动了连接着方向舵动力控制组件的曲柄移动，它提供液压压力给员筒型作动筒，作的筒作的使得方向舵移动。 LESSON 16 POWER PLANT (1) 一、单词二、TEXT 动力装置 Power plant 推力 thrust 帮助 aid 反推装置 Thrust reverser 驱动 drive 齿轮箱 gearbox 高函道比 High bypass rate 涡轮风扇 turbofan 装配 fitting 相同的 轴流 axes 转子 rotor 定子叶片 State vane 压缩机 compressure 经由 Via 轴 shaft 涡轮 turbine 机械地 mechanically 独立的 independent 相互 Each other 气流 Airstream 燃烧 combusion 环形的 提高 increase 排气 Discharger air 能够 Is capable of 大约 approximately 主要的 major 组件 module 核心 core 附件齿轮箱 Accessory gearbox 维护 maintenance 助推器 booster 轴承支座 Bearing support 入口 inlet 支架 frame 喷嘴 nozzle 防护罩 shroud 转换 transfer 继续 continue 加速 accelerate 引导 direct 结果 result 交付 deliver 用泵抽 pump (1) the power plant on the 737-300/400/500 provides the thrust required for flight and also supplies power to in stopping the airplane (thrust reversers ), provides bleed air for air conditioning, pressurization, anti-icing , and drives a gearbox used for electrical power and hydraulic power. The 737 airplane are powered by two wing-mounted CFM 56-3 high bypass-ratio turbofan engine, the engine buildup is identical for left or right engines. |
