Swept wings are therefore almost always used on jet aircraft designed to fly at these speeds. The term "swept wing" is normally used to mean "swept back", but variants include forward sweep, variable sweep wings and oblique wings in which one side sweeps forward and the other back. The delta wing is also aerodynamically a form of swept wing.
A fixed-wing aircraft may have more than one wing plane, stacked one above another: Biplane: two wing planes of similar size, stacked one above the other.The biplane is inherently lighter and stronger than a monoplane and was the most common configuration until the 1930s.
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.
Flying wings lack a distinct fuselage, with crew, engines, and payload contained within the wing structure.

Kyushu J7W1 Shinden fuselage at the National Air and Space Museum Washington, DC. The two prototypes were the only examples of the Shinden ever completed. After the end of the war, one was scrapped; the other was claimed by a U.S. Navy Technical Air Intelligence Unit in late 1945, dismantled, and shipped to the United States.
Variable-sweep wing or "swing wings" that allow outstretched wings during low-speed flight (e.g., take-off, landing and loitering) and swept back wings for high-speed flight (including supersonic flight), such as in the F-111 Aardvark, the F-14 Tomcat, the Panavia Tornado, the MiG-23, the MiG-27, the Tu-160 and the B-1B Lancer.
Stratolaunch, a Seattle aerospace company formed by Microsoft cofounder Paul Allen, completed the ninth test flight of its world's biggest airplane. The biggest plane in the world has wings longer ...
One problem with the forward-swept design is that when a swept wing yaws sideways (moves about its vertical axis), one wing retreats while the other advances. On a forward-swept design, this reduces the sweep of the rearward wing, increasing its drag and pushing it further back, increasing the amount of yaw and leading to directional instability.
