Horseshoe vortex

Any change in lift distribution sheds a new trailing vortex, according to the lifting-line theory

A realistic lift distribution causes the shedding of a complex vorticity pattern behind the aircraft.

The horseshoe vortex model is a simplified representation of the vortex system of a wing. In this model the wing vorticity is modelled by a bound vortex of constant circulation, travelling with the wing, and two trailing wingtip vortices, therefore having a shape vaguely reminiscent of a horseshoe. A starting vortex is shed as the wing begins to move through the fluid, which dissipates under the action of viscosity, as do the trailing vortices far behind the aircraft.
