The F-111 was the first variable-sweep wing aircraft to be put into production. Shown are three Australian F-111s. F-111E on display at the Museum of Aviation, Robins AFB, United States. The earliest use of variable sweep was to trim the aeroplane for level flight.
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 ...
Developed from the Sukhoi Su-7, the Su-17 was the first variable-sweep wing aircraft to enter Soviet service and featured updated avionics. The aircraft also has variants which were designed to be exported to non-Soviet states such as the Sukhoi Su-22 and the less popular Su-20. It was produced from 1967 to 1990.
First flight by an aircraft with variable-sweep wings: was by the tailless Westland-Hill Pterodactyl IV with Flight-Lieutenant Louis G. Paget at the controls in April or May 1931. The wing sweep could be adjusted by 4.75 degrees in flight to provide trim adjustment. [187]
After the war, in the 1940s and 1950s, Baynes was busy with research in the area of variable-sweep supersonic aircraft. In 1949 he applied for a patent on his design for a supersonic variable-sweep wing and tail fighter. [6] The design was built and wind tunnel test were completed successfully.
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.
Developed in the 1960s by General Dynamics under Robert McNamara's TFX Program, the F-111 pioneered variable-sweep wings, afterburning turbofan engines, and automated terrain-following radar for low-level, high-speed flight. Its design influenced later variable-sweep wing aircraft, and some of its advanced features have become commonplace.
The Panavia Tornado is a family of twin-engine, variable-sweep wing multi-role combat aircraft, jointly developed and manufactured by Italy, the United Kingdom and Germany. [ a ] There are three primary Tornado variants : the Tornado IDS ( interdictor / strike ) fighter-bomber , the Tornado ECR ( electronic combat / reconnaissance ) SEAD ...
