Abstract
Among the aeroelastic phenomena that affect flexible and very flexible aircraft, those caused by gusts deserve special attention due to their potential in increasing structural loads and decreasing flying qualities. In this work, the gust load alleviation on a smart idealized wing by active, model-based control is analyzed and experimentally tested in a wind-tunnel facility. The results show a considerable attenuation of the wing root bending moment by decreasing the amplitude of oscillations resulting from gust disturbances, especially at the frequency of the wing's first bending moment via feedback of observed output.
