If damping ratio is 0.05 then, find the lift to drag ratio. Consider 2-degree phugoid approximation.(a) 14.14(b) 20(c) 25(d) 0.05I have been asked this question in a national level competition.The origin of the question is Dynamic Stability topic in portion Stability, Control, and Handling Qualities of Aircraft Design

Answer»

Correct answer is (a) 14.14

For EXPLANATION: GIVEN damping RATIO d = 0.05

Lift to DRAG = 0.707/d = 0.707/0.05 = 14.14.
