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 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 Grumman XF10F Jaguar was a prototype swing-wing fighter aircraft offered to the United States Navy in the early 1950s. Although it never entered service, its research paved the way toward the later General Dynamics F-111 and Grumman's own F-14 Tomcat .
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.
Boeing also faced insurmountable weight problems due to the swing-wing mechanism, a titanium pivot section having been fabricated with a weight of 4,600 pounds (2,100 kg) and measuring 11 feet (3.4 m) long and 2.5 feet (76 cm) thick, [16] and the design could not achieve sufficient range. Flexing of the fuselage (it would have been the longest ...
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.
This swing comes in four different colors, too, which is a bit of an oddity when it comes to sex swings (they mostly come in black). So, you and your partner can properly decorate your love nest ...
Swing-wing aircraft that mount pylons on the moving portion of the wing (such as the General Dynamics F-111 and the Panavia Tornado) must include a mechanism for swiveling the pylon as the wing sweeps fore or aft, in order to keep the pylon and store facing directly forwards at all times. The F-111's outermost pair of hardpoints do not swivel ...
