Keywords: unsteady flow, euler equations, moving meshes, aeroelastic coupling, active control

Independent structural dynamic and inviscid aerodynamic models are coupled, in the time domain, and two-dimensional transonic flutter suppression via active flap control is simulated. The method developed is used to simulate transonic aeroelasticity in the time domain, and to compute stability (flutter) boundaries of 2-D wing sections.
