Question
The "Yaw Damper System" provides airplane stabilization about the yaw axis.
The Yaw Damper minimizes dutch roll during flight by providing rudder
displacement proportional to, and opposing, the yaw rate of the airplane.
Transfer function of the yaw damper is taken as:
4.833
yaw rate
rudder angle
(s+0.551)(s+0.1 ±0.541*i)
(s+0.616)(s +0.058+ i)(s+0.007)
a) Give a brief knowledge about yaw dampers.
b) Draw and interpret "root-locus" graphic of this transfer function.
c) Draw and interpret the yaw rate distribution according to time.
