This paper describes the functional requirements and design of an aeroelastic wing model for wind tunnel investigations of vibration and flutter suppression using flap or piezoelectric actuation. Finite element and flutter prediction analyses of the model are incorporated. Analytical results show that the model provides an envelope of 25 % in velocity for flutter suppression testing, utilizing a 'flutter stopper' device as a safety mechanism. Open-loop tests show that a margin of 6 % is achieved in the wind tunnel.
