In a nacelle and wing combination where a vortex is shed from a side surface portion of the nacelle and said vortex burst prematurely to reduce lift, the improvement comprising a vortex control device located in an upwash region along the side of the nacelle to cause said vortex to form in the critical vortex control region where boundary layer is relatively thin and local velocity is relatively high. This strengthens the vortex to inhibit vortex bursting at the burst location.
