This video shows the flow pattern over a nonslender flying wing using surface flow visualization technique. It reveals symmetrical wave-like surface flow structures with vortex breakdown at zero sideslip angle. With increasing sideslip angle, on the windward side, a recirculating flow is observed near the leading edge of the wing and it is seen to be associated with the wave-like structure. Also, flow reversal is observed near the trailing edge of wingtip on the windward structure.
