  2. Variable-sweep wing - Wikipedia

    en.wikipedia.org/wiki/Variable-sweep_wing

    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.

  3. Wing configuration - Wikipedia

    en.wikipedia.org/wiki/Wing_configuration

    A tandem wing design has two wings, one behind the other: see Tailplanes and foreplanes below. Some early types had tandem stacks of multiple planes, such as the nine-wing Caproni Ca.60 flying boat with three triplane stacks in tandem. A cruciform wing is a set of four individual wings arranged in the shape of a cross. The cross may take either ...

  4. Blohm & Voss P.202 - Wikipedia

    en.wikipedia.org/wiki/Blohm_&_Voss_P.202

    The wing span was 12.0 metres (39.4 ft) when unswept and 10.0 metres (32.8 ft) when fully swept. [3] The long main undercarriage retracted into the wing, while a nose wheel completed the tricycle undercarriage. [4] The P.202 was powered by a pair of BMW 003 turbojets, slung underneath the fuselage centre section and exhausting behind the wing.

  5. Swept wing - Wikipedia

    en.wikipedia.org/wiki/Swept_wing

    The Su-47 uses a forward wing sweep, while the Su-27s sport a more conventional backward-swept design. A swept wing is a wing angled either backward or occasionally forward from its root rather than perpendicular to the fuselage. Swept wings have been flown since the pioneer days of aviation.

  6. Bell X-5 - Wikipedia

    en.wikipedia.org/wiki/Bell_X-5

    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 ...

  7. Dihedral (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Dihedral_(aeronautics)

    This is to compensate for other design elements' influence on the dihedral effect. These other elements (such as wing sweep, vertical mount point of the wing, etc.) may be more difficult to change than the dihedral angle. As a result, differing amounts of dihedral angle can be found on different types of fixed-wing aircraft.

  8. Washout (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Washout_(aeronautics)

    The Hornet has approximately 4 degrees of washout. Washout is a characteristic of aircraft wing design which deliberately changes the lift distribution across the span of an aircraft’s wing. The wing is designed so that the angle of incidence is greater at the wing roots and decreases across the span, becoming lowest at the wing tip.

  9. Vortex lift - Wikipedia

    en.wikipedia.org/wiki/Vortex_lift

    Four basic configurations which have used vortex lift are, in chronological order, the 60-degree delta wing; the ogive delta wing with its sharply-swept leading edge at the root; the moderately-swept wing with a leading-edge extension, which is known as a hybrid wing; and the sharp-edge forebody, or vortex-lift strake.
