Effects of nonlinear aeroelastic response in transonic flow regime has been observed for pitching and plunge movements with structural nonlinearities. The Euler equations solver has been based on an unsteady finite volume algorithm. The aeroelastic response are analised by investigating time history and phase plane by Runge-Kutta method.
