Outline of Final Research Achievements

Combination of computational and experimental studies in the three-years of period showed that plasma actuators (very efficient flow control devices) improve improve aerodynamic performance not only at stall conditions but also cruise conditions for the first time. With feed-back process being added, effective parameters were automatically selected and plasma actuators showed still more efficient control authority. The result was successfully applied to the flows over a pitching airfoil.
From extensive studies in the past, design guidance of plasma actuators was proposed. The results were presented in more than 10 academic journals.
