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 ...

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.
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 origins of the P.1052 were in a 1945 design study by the Hawker design team for a development of the P.1040 using swept back wings. Interest was not shown by the Ministry of Supply until the spring of 1946 when Air Ministry specification E.38/46 (to undertake studies into the aerodynamic properties of swept wings) was issued, and a contract awarded in May 1947 for Hawker to supply two ...
The wings can sweep from 15 degrees to 67.5 degrees (full forward to full sweep). Forward-swept wing settings are used for takeoff, landings and high-altitude economical cruise. Aft-swept wing settings are used in high subsonic and supersonic flight. [74] The B-1's variable-sweep wings and thrust-to-weight ratio provide it with improved takeoff ...
The L-39-2 was retained by Bell to support their X-2 program, being modified with a new fully swept wing of a design intended for the X-2. [ 1 ] [ 3 ] On December 12, 1949, both aircraft were transferred to the Lewis Research Center before being sold for scrap in 1955.
The Grumman X-29 is an American experimental aircraft that tested a forward-swept wing, canard control surfaces, and other novel aircraft technologies. Funded by NASA, the United States Air Force and DARPA, the X-29 was developed by Grumman, and the two built were flown by NASA and the United States Air Force. [1]
