I sincerely require help to understand how to go about handling
this kinds of question.
Please kindly do not copy and paste from previous questions
posted previously.
A step by step approach and neat hand writing will be
appreciated.
Thank you once again.
(b) The roll response to aileron control of the Douglas DC-8 airliner in an approach flight condition is given by the following transfer function: o(s) 0.726 8(s) (s +1.121) = (i) Plot the time history of the roll angle o, when subjected to a unit aileron impulse input. (3 marks) (ii) Plot the time history of the roll angle o, when subjected to a unit aileron step input. (3 marks) (iii) Define the time-constant for the time history plots. (3 marks) (iv) Develop an expression for ยบ(s), if the pilot executes a "singlet" aileron input as shown in Figure Q1(b)(iv). (6 marks) 1.5 1 1 a Sa -0.5 -2 0 2 4 8 10 0.5 time (sec) Figure 01(b)(iv)
