Abstract
<p>We propose a tangential blowing cylinder, a type of circulation control wing, to control the direction of a jet replacing a blade or a cascade. Flow characteristics including deflection are experimentally investigated. Specifically, visualization observations, velocity distribution measurements, and the effects of momentum ratio, injection angle, and location of the cylinder on the deflection angle of the jet are analyzed. The stalling at an angle-of-attack above 20° with a single blade impedes direction control for such large angles. However, the jet may be bent to approximately 90° by using the proposed tangential blowing cylinder. The optimal injection angle for controlling the jet direction and the unsteady characteristics downstream of the tangential blowing cylinder are also determined.</p>
