Developments in adaptive materials (or smart structures) have led to their use for actuators in aeroservoelastic applications. Tests demonstrating feasibility of adaptive materials based actuation have been conducted on small geometrically scaled models, and aeroelastic scaling has been disregarded. The primary objectives of our research activity were: (1) development of innovative aeroelastic scaling laws for aeroservoelastic and nonlinear aeroelastic problems, which allow one to extrapolate results, obtained from model tests to the full-scale configuration, and (2) application of the scaling laws to configurations illustrating difference between geometric and aeroelastic scaling. The primary accomplishments were: (1) development of a novel two pronged approach for generating innovative aeroelastic scaling laws for nonlinear aeroelastic and aeroservoelastic problems, and (2) developed scaling laws for flutter suppression in subsonic and transonic flow. In addition to conventional scaling parameters these requirements also address the sealing of control hinge moments and power required for flutter suppression. The research described has made an important contribution to the state-of-the-art.
