Keywords: delta wing, vortex breakdown, blowing, hot-wire anemometer

In this paper at first, the characteristics of the leading edge vortex before vortex breakdown or after vortex breakdown were studied by the low speed wind tunnel experiment. Next, in order to control the vortex breakdown, blowing of several different conditions are carried out and effects are investigated.
