Outline of Final Research Achievements

When a slender body, which is typical body shape of a rocket and an air plane, flies at high angle of attack, separation flow over the body becomes asymmetric and the attitude stability is significantly lost due to the side force caused by the asymmetric separation flow. To overcome this difficulty, the plasma actuator, which is one of advanced flow control devices, was applied to the high-angle-of-attack slender body for suppressing the asymmetricity in the separation flow. As a result, this study successfully showed that the side force can be continuously changed to zero by burst-mode actuation of plasma actuators installed to the apex of the body.
