BAe146型飞机的偏航阻尼器系统是英国 Smiths 公司生产的由两套独立而又有机结合的双重系统组成。它们分别感受偏航率和侧向加速度信号,共同自动控制飞机的方向舵面,保持飞机的偏航稳定性。在飞机转弯状态,根据飞机的横滚坡度和横滚率自动转动方向舵,防止飞机侧滑。因此,该系统通常从起飞到着陆的整个飞行航段都要使用。 The yaw damper system of the BAe146 aircraft is made up of two independently and organically integrated dual systems manufactured by the Smiths Company in the United Kingdom. They experience the yaw rate and lateral acceleration signals respectively, and jointly control the aircraft’s rudder surface to maintain the yaw stability of the aircraft. In the aircraft turning state, according to the aircraft’s roll gradient and roll rate automatically turn the rudder, to prevent the aircraft skidding. Therefore, the system is usually used throughout the flight from take-off to landing.
