Velocity, Inc. is an American kit aircraft manufacturer. The company was founded in 1984 by Danny Maher, marketing a four-seat homebuilt aircraft based on the Long-EZ design. The first prototype flew in 1985. The company was sold to Scott and Duane Swing in 1992. In 1995, the cockpit design was changed, adding a gull wing door design. [1]
A variable-sweep wing, colloquially known as a "swing wing", is an airplane wing, or set of wings, that may be modified during flight, swept back and then returned to its previous straight position. Because it allows the aircraft's shape to be changed, it is a feature of a variable-geometry aircraft.
The Volmer VJ-23 Swingwing is an American high-wing, single-seat, foot launched glider that was designed by Irv Culver and built by Volmer Jensen and supplied as plans by his company Volmer Aircraft for amateur construction. Kits were also available from DSK Aircraft. [1] [2]
A composite photograph showing the Bell X-5’s variable-sweep wing. The Bell X-5 was the first aircraft capable of changing the sweep of its wings in flight. It was inspired by the untested wartime P.1101 design of the German Messerschmitt company. In a further development of the German design, which could only have its wing sweepback angle ...
The swing-wing was also used by the older American General Dynamics F-111 Aardvark strike fighter, and the Soviet Mikoyan-Gurevich MiG-23 fighter. The smaller Tornado has many similarities with the F-111, however the Tornado differs in being a multi-role aircraft with more advanced onboard systems and avionics.

The first variable-sweep aircraft from Dassault emerged as the single-engined, two-seat Mirage G fighter in 1967, essentially a swing wing version of the Mirage F2.The wings were swept at 22 degrees when fully forward and 70 degrees when fully aft and featured full-span double-slotted trailing edge flaps and two-position leading edge flaps.
A variable-sweep wing (swing-wing) is a type of pivoted wing that takes advantage of the aerodynamics of a swept wing at high speeds while swinging straight to avoiding the drawbacks of such a design at lower speeds.
