Tutorial Sheet 3

Question 1

How to calculate steady-state roll response?

Answer 1

1. Equation sheet for roll response (p[t])
2. Ignore (1-e^[-t/tc]) (steady-state). This equals pss.
3. Sub-in values in equation sheet.
4. Solve

Question 2

When asked about full aileron deflection, how to you verify whether it’s valid?

Answer 2

Use pssb/2u0 equation and compare to reference values on equation sheet.

Question 3

General characteristic equation
