要想对安定面配平系统有个大概的了解,先了解一下以下几个电门的功能:
Column Cutout Switches:The column cutout switches stop the stabilizer trim actuator when the pilot moves the control column in a direction opposite to the trim direction
驾驶杆切断电门:当驾驶杆的方向和配平方向相反时,驾驶杆切断电门停止安定面配平作动筒工作
Stabilizer Trim Override Switch:The pilots use the stabilizer trim override switch on the aisle stand to bypass the column cutout switches if one or both fail.
安定面配平超空电门:旁通杆切断电门
Stabilizer Trim Cutout Switches:The pilots use the stabilizer trim cutout switches on the control stand to stop the main electric and autopilot runaway trim inputs to the stabilizer trim actuator.安定面配平切断电门:将主电配平和自动驾驶配平切断
Flaps Up Switch:The flaps up switch controls the main electric operation speed of the stabilizer trim actuator. The autopilot electric control of the stabilizer trim actuator does not go through the flaps up switch. 襟翼收上电门:当襟翼收上和没收上时安定面主电配平的速度是不一样的。
Stabilizer Trim Limit Switches:The stabilizer trim limit switches limit the range of stabilizer motion. 安定面配平的极限电门,一共有5个,在狗洞里。系统的方框图结合部件的位置及功能走个两三遍,基本上系统的工作方式原理也就了然于心了 |
