Wingtip vortices can pose a hazard to aircraft, especially during the landing and takeoff phases of flight. The intensity or strength of the vortex is a function of aircraft size, speed, and configuration (flap setting, etc.). The strongest vortices are produced by heavy aircraft, flying slowly, with wing flaps and landing gear retracted ...
The Ha 137 prototype aircraft, fitted with vertical wing extensions, c.1935–1937. The initial concept dates back to 1897, when English engineer Frederick W. Lanchester patented wing end-plates as a method for controlling wingtip vortices. [3]

Outboard tail. An outboard tail is located outboard of the main wing tips. Although sometimes described as tailless, the outboard tail configuration differs from a tailless wing in that the horizontal stabilizer is discontinuous from the main wing surface, typically being set further back and requiring a short boom to support it.
Aircraft may have additional minor aerodynamic surfaces. Some of these are treated as part of the overall wing configuration: Winglet: a small fin at the wingtip, usually turned upwards. Reduces the size of vortices shed by the wingtip, and hence also tip drag. Strake: a small surface, typically longer than it is wide and mounted on the ...

Four basic configurations which have used vortex lift are, in chronological order, the 60-degree delta wing; the ogive delta wing with its sharply-swept leading edge at the root; the moderately-swept wing with a leading-edge extension, which is known as a hybrid wing; and the sharp-edge forebody, or vortex-lift strake. [7]
These vortices are known as wingtip vortices and are formed by fluid flowing around the wingtips from the high-pressure region that is the bottom of the wing to the low-pressure region that is the top of the wing. The flow becomes separated from the airfoil and rotates about a low pressure wake that forms the core of the vortex.
