Airfoils shelf life is strongly reduced by the application of unsteady loads, which can bring to fatigue phenomena and non-stable performance of the device. In this context, this paper carries out an evaluation of an unsteady application of Dielectric Barrier Discharge Plasma Actuator (DBD-PA) to reduce loads variability on a pitching airfoil, with the aim to increase the aerodynamic profiles durability and thus to increase airfoil stability. The comparison, in order to evaluate the effect of actuators dimensions, involves two different devices, with a high voltage electrode length one order of magnitude different.

Abstract
Airfoils shelf life is strongly reduced by the application of unsteady loads, which can bring to fatigue phenomena and non-stable performance of the device. In this context, this paper carries out an evaluation of an unsteady application of Dielectric Barrier Discharge Plasma Actuator (DBD-PA) to reduce loads variability on a pitching airfoil, with the aim to increase the aerodynamic profiles durability and thus to increase airfoil stability. The comparison, in order to evaluate the effect of actuators dimensions, involves two different devices, with a high voltage electrode length one order of magnitude different.File in questo prodotto:
