  2. Wing configuration - Wikipedia

    en.wikipedia.org/wiki/Wing_configuration

    The wing configuration of a fixed-wing aircraft (including both gliders and powered aeroplanes) is its arrangement of lifting and related surfaces. Aircraft designs are often classified by their wing configuration. For example, the Supermarine Spitfire is a conventional low wing cantilever monoplane of straight elliptical planform with moderate ...

  3. Forward-swept wing - Wikipedia

    en.wikipedia.org/wiki/Forward-swept_wing

    An early example to fly, in 1940, was the Soviet Belyayev DB-LK, a twin-boom design with forward-swept outer wing sections and backwards-swept tips. It reportedly flew well. It reportedly flew well. Belyayev's proposed Babochka research aircraft was cancelled following the German invasion.

  4. 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 an example of a variable-geometry aircraft. A straight wing is most efficient for low ...

  5. Airfoil - Wikipedia

    en.wikipedia.org/wiki/Airfoil

    An airfoil (American English) or aerofoil (British English) is a streamlined body that is capable of generating significantly more lift than drag. [ 1 ] Wings, sails and propeller blades are examples of airfoils. Foils of similar function designed with water as the working fluid are called hydrofoils.

  6. Oblique wing - Wikipedia

    en.wikipedia.org/wiki/Oblique_wing

    Oblique wing. An oblique wing (also called a slewed wing) is a variable geometry wing concept. On an aircraft so equipped, the wing is designed to rotate on center pivot, so that one tip is swept forward while the opposite tip is swept aft. By changing its sweep angle in this way, drag can be reduced at high speed (with the wing swept) without ...

  7. Swept wing - Wikipedia

    en.wikipedia.org/wiki/Swept_wing

    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.

  8. NACA airfoil - Wikipedia

    en.wikipedia.org/wiki/NACA_airfoil

    A: blue line = chord, green line = camber mean-line, B: leading-edge radius, C: xy coordinates for the profile geometry (chord = x axis; y axis line on that leading edge) The NACA airfoil series is a set of standardized airfoil shapes developed by this agency, which became widely used in the design of aircraft wings.

  9. Trapezoidal wing - Wikipedia

    en.wikipedia.org/wiki/Trapezoidal_wing

    Trapezoidal planform. In aeronautics, a trapezoidal wing is a straight-edged and tapered wing planform.It may have any aspect ratio and may or may not be swept. [1] [2] [3]The thin, unswept, short-span, low-aspect-ratio trapezoidal configuration offers some advantages for high-speed flight and has been used on a small number of aircraft types.
