We must calibrate sensor against angular displacement for airplanes ’ aileron , jaw rudder and elevator , and so on , when making airplanes and testing on their flying capabilities . all the methods reported aren ’ t applicable because of its special working environment here 在飞机生产和对飞机进行飞行性能试验的过程中,都要对飞机的副翼、襟翼、方向舵和升降舵等转动系统的角位移传感器进行标定。
Several icing parameters were imported to calculate the change of drag coefficient and typical derivatives between clean aircraft and iced aircraft , and the aircraft flight envelope change of iced and un - iced situation was computed , and the small disturbance flight dynamics model was modified to study the effect of the ice accretion on the aircraft dynamics by importing the ice parameter to it , and the longitudinal and lateral stability and the elevator , aileron and rudder step response were also studied and simulated 根据这些参数计算了飞机结冰后阻力系数以及典型气动导数的变化，并计算了结冰前后飞机的飞行包线；同时对结冰前后飞机的纵向、横侧动稳定性以及升降舵、副翼和方向舵阶跃操纵响应进行仿真计算。
