The present invention relates to an Active Control Surface Modal (ACSM) device that generates unsteady aerodynamic damping to alleviate aeroelastic structural instability, vibration and dynamic loads. An active control surface modal deformation is created by means of a pair of antagonistically activated actuators. Since the masses of upper and lower surface skins are lighter, the modal deformations can be activated at high frequencies that can encompass wide band spectrum of buffet, gust and flutter problem areas. An independent dosed loop active control...
1. A control surface having a leading edge and a trailing edge and a spanwise extending spar rotatably hinged at its leading edge on an aerodynamic lifting surface comprising:an upper skin fixed to the spar of the control surface extending spanwise and extending chordwise from the leading edge of the control surface to the trailing edge of the control surface and having an outer surface and an opposed inner surface; a lower skin fixed to the spar extending spanwise and extending chordwise from the leading edge of the control surface to the trailing edge ...
