A variable-sweep wing was selected as the winning design used by Boeing's entry in the FAA's study for a supersonic transport, the 2707. However it evolved through several configurations during the design stage, finally adding a canard, and it eventually became clear that the design would be so heavy that it would be lacking sufficient payload ...
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 HFB 320 Hansa Jet used forward sweep to prevent the wing spar passing through the cabin. Small shoulder-wing aircraft may use forward sweep to maintain a correct CoG. Some types of variable geometry vary the wing sweep during flight: Swing-wing: also called "variable sweep wing". The left and right hand wings vary their sweep together ...
The Rockwell B-1 Lancer [b] is a supersonic variable-sweep wing, heavy bomber used by the United States Air Force.It has been nicknamed the "Bone" (from "B-One"). [2] [3] As of 2024, it is one of the United States Air Force's three strategic bombers, along with the B-2 Spirit and the B-52 Stratofortress.
The Beechcraft Starship has variable-sweep foreplanes. The Beechcraft Starship has a variable-sweep canard surface. The sweep is varied in flight by swinging the foreplanes forward to increase their effectiveness and so trim out the nose-down pitching effect caused by the wing flaps when deployed. [44]
Flexing of the fuselage (it would have been the longest ever built) threatened to make control difficult. In October 1968, the company was finally forced to abandon the variable geometry wing. [17] [18] The Boeing team fell back on a tailed delta fixed wing. The new design was also smaller, seating 234, and known as the Model 2707-300. Work ...
The wing has four sweep settings: 16° for takeoff and landing, 35° and 45° for cruise at different altitudes, and 69° for minimum aspect ratio and wing area in low-level dashes. The variable geometry wing provides excellent STOL performance, allowing a landing speed of 230 kilometers per hour (140 mph), even lower than the Sukhoi Su-17 ...
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. The term variable-geometry wing is often used synonymously with variable-sweep, though strictly speaking it is a type of variable ...
