摘要：

The feasibility of vortex control by using suction via slit on the upper surface of a delta wing is demonstrated. Flow visualization were carried out in a wind tunnel on both the leading-edge suction and surface suction of two similar model delta wings. The effect of suction has been found more effective in delaying vortex breakdown for suction slits closer to the leading edge. The exact mechanism of how the surface suction affects vortex breakdown is not clear. However, surface suction is less effective than the leading-edge suction.
