located in the lower nose compartment. The roll CWS force transducer is
connected between the bus drum and the control drum, the output of the
force transducer provides signals to the autopilot. The aileron force limiter
limits control wheel movement during A/P operation, the control wheel
rotation is limited to 17°with flaps up and 25°with flaps down.
副翼位于每個機翼前緣外側,其它副翼組件位于3 個主要區域:
駕駛艙
控制輪位于駕駛艙前部。副翼配平開關位于控制臺上。
輪艙區域
副翼動力控制組件(PCU,轉變駕駛員或自動駕駛系統機械驅動的輸
入為液壓驅動機械輸出,用以驅動副翼)位于主輪艙前壁。自動駕駛
副翼作動筒主輪艙前壁。副翼位置傳感器從副翼系統提供兩個位置反
饋信號給自動駕駛系統。
機頭下方
控制鼓及轉動鼓輪連接到控制輪上,位于機頭下方。橫滾駕駛盤操縱
反向換能器連接在轉動鼓輪與控制鼓之間,力量轉換器的輸出為自
動駕駛提供信號。副翼操縱力限制器限制控制輪在自動駕駛儀操作時
移動。控制輪的轉動被限制在襟翼上升17°及襟翼下降25°之間。
(4) To understand elevator poeration consider the airplane balanced about the
center of lift (CL). The center of gravity (CG) is shown forward of the
center of lift. The stabilizer provides a counter force to the CG. The
stabilizer may be trimmed to changer the force as required to maintain
balance.
The elevators are used to change the pitch attitude. Moving the elevators
out of their faired position causes the airplane to change the pitch attitude
about the lateral axis. The amount of elevator movement establishes the
airplane pitch rate.When the desired attitude is reached, the elevators are
faired and the air-plane maintains the new pitch attitude.
升降舵操作要考慮飛機相對于升力中心的平衡。重力中心一般在升力
中心的前面。安定面提供一個反向力給重力中心。安定面也可以在需
要時通過配平改變力量以保持平衡。
升降舵用來改變飛機俯仰姿態。移動升降舵離開它們的流線型位置,
使得飛機改變水平軸上的俯仰姿態。升降舵的移動量形成俯仰率。當
達到希望的姿態時,升降舵再成流線型,飛機保持新的俯仰姿態。
(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.
兩個駕駛桿提供飛機俯仰控制。每個控制桿通過地板沿伸到前艙。一
個扭個管將駕駛桿連在一起。駕駛桿允許駕駛員沿水平軸控制飛機。
(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.
飛機垂直方向上的控制由方向舵提供。通過一個單獨的不含調整片的
方向舵提供控制。方向舵由機長或副駕駛的腳蹬控制。隨著腳蹬的移
動,使得前扇形盤轉動,前扇形盤由線纜連接到后扇形盤。后扇形盤
的轉動帶動一個連接著一個扭力管的操縱桿。扭力管的轉動帶動了連
接著方向舵動力控制組件的曲柄移動,它提供液壓壓力給員筒型作動
筒,作的筒作的使得方向舵移動。
