Smart Blade Flutter Alleviation
In this paper, the effect of using a piezoelectric material has been shown on postponing the flutter phenomenon on a regular blade. System response of a smart blade with only flap-wise and edgewise plunge DOF shows that the oscillations of the smart blade can be effectively decayed in a very short time using efficient piezopatches in the flap-wise and edgewise plunge DOF. Furthermore, in a smart blade with four DOF, it has been indicated having piezopatches in flap-wise and edgewise plunge DOF can defer the flutter speed 81.41% which is a noticeable increase in the flutter speed. Finally, by adding a piezopatch to the pitch DOF to a smart blade, it is possible to postpone the flutter speed 155% which is a very considerable increase.
