In this paper flight dynamics of a UAV with high aspect ratio wing has been simulated. Mean axis theory was the base of simulation and flight dynamics and vibration equations have been coupled through interaction of aerodynamic loads. Mode shapes of the structure has been extracted by software and introduced to the equations. Response to step deflection of elevator has been simulated and a comparison has been made with rigid vehicle.
