Based on the self-induction theory where the spiraling shear layer and the straight path of the vortex core are regarded as the cause of the vortex breakdown, it is demonstrated that the vortex breakdown can be suppressed by reconfiguring the delta-wing planform from a conventional straight leading edge to a shaped form. The wavy wing tested is just one example of such a shaped planform, of which there may be many possible variations. For instance, even with only the first and second wave, the same results are likely to be achieved. (After the initial submission of the present Note, this expectation was indeed confirmed by the authors.)
