Abstract
In this work, it has been shown the effect of a piezoelectric material on postponing the flutter phenomenon and even removing it completely on a regular wing. First, the system response of a smart wing with only plunge DOF and pitch DOF are presented. Using an efficient piezopatch can effectively decay the oscillations of the smart wing in a very short time. In addition, implementing one piezopatch in the plunge DOF of a regular wing with three DOF can postpone the flutter speed by 81.41%, which is a considerable increase in the flutter speed. We then present the effect of adding one more piezopatch to a smart wing in the pitch DOF to further postpone the flutter phenomenon. The flutter speed in a smart wing can be postponed by 115.96%, which is a very considerable value. Finally, adding one more piezopatch on a smart wing in the control DOF can completely remove the flutter phenomenon from the wing, which represents a great achievement in the dynamic aeroelectic behavior of a wing.
