| Abstract: | This paper presents dynamic and aero elastic characteristics simulation of a composite light trainer aircraft using Msc/ Nastran code and typical section method. Correlation of dynamic characteristics of aircraft with results obtained from ground vibration test of aircraft was studied. Critical flutter, divergence and control reversal velocities of complete aircraft were computed. Close agreement was observed between computational and experimental frequencies. Aircraft had a flutter margin (23%) against required (20%) as per FAR 23. |
