The Roll Angle Response To Aileron Control Of The Douglas Dc 8 Airliner In An Approach Flight Condition Is Given By The 1 (34.21 KiB) Viewed 42 times

The roll angle response to aileron control of the Douglas DC-8 airliner in an approach flight condition is given by the following transfer function (it relates the roll angle and aileron input da): D (s) -0.726 (s² + 0.421s + 0.889) Aa(s) (s 0.013)(s + 1.121) (s² + 0.22s +0.99) a) Find the poles of the transfer function, define the corresponding modes for the lateral dynamics, and determine stability of the modes. b) Find the roll angle of the airplane as a function of time (p(t)) when the aileron input is a unit impulse.
