Abstract

In this study, dynamic trailing-edge deflections with different kinematics were applied on a high-angle-of-attack translating wing. The effects of trailing-edge-deflection speed and timing were investigated through PIV and force measurements. Both the PIV and force measurement results indicate that the trailing edge deflection timing play a more important role than that of deflection speed. Specially, by changing the trailing-edge-deflection timing, three different flow patterns were captured while varying deflection speed results in similar flow patterns. The force measurements show that a 22% variation of mean lift can be achieved by changing the trailing edge deflection timing while much less variation was found with deflection speed varying.
