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 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 adjusted on the ground, the Bell engineers devised a system of electric ...
The aircraft is predominantly made from wood and covered in doped Ceconite. The wing leading edge is made from poplar plywood and supported by nose ribs made from marine-grade plywood. The wing spar cap strips and tail ribs are fashioned from spruce. The tailboom is an aluminium tube. Its wing is cantilevered and tapered from wing root to wing ...
The unit later also acquired nine Cessna and Beechcraft King Air fixed-wing aircraft. [7] In line with typical CIA practices, these helicopters and aircraft were not included in the official register of U.S. Army aircraft and were instead registered as belonging to a company called Aviation Tech Services.

Boeing's entry was essentially identical to the swing-wing Model 733 studied in 1960; it was known officially as the Model 733-197, but also referred to both as the 1966 Model and the Model 2707. The latter name became the best known in public, while Boeing continued to use 733 model numbers internally.
The ASW 19 Club is a version with a fixed unsprung monowheel and no water ballast carried. Only five were built for the Royal Air Force , where they were known as the Valiant TX.1 . At the Delft University of Technology a single ASW 19 was fitted with a new wing profile featuring turbulator blow holes.
A straight-winged North American FJ-1 flying next to a swept-wing FJ-2 in 1952.. There are three main reasons for sweeping a wing: [1] 1. to arrange the center of gravity of the aircraft and the aerodynamic center of the wing to coincide more closely for longitudinal balance, e.g. Messerschmitt Me 163 Komet and Messerschmitt Me 262.
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.
