Consider the aircraft with weight of 1234 kg. Find the approximate value of the damping ratio if time taken by system for damping is minimum.(a) 1(b) 1.7(c) 1.9(d) 0.002The question was asked in a job interview.My doubt is from Dynamic Stability topic in chapter Stability, Control, and Handling Qualities of Aircraft Design |
Answer» RIGHT choice is (a) 1 For EXPLANATION I would say: For minimum damping time, system should be CRITICALLY damped. For, critical damping RATIO is defined as, Damping ratio = damping coefficient/critical damping coefficient = Cc/Cc = 1. |
