  2. Aspect ratio (aeronautics) - Wikipedia

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

    Aspect ratio (aeronautics) An ASH 31 glider with very high aspect ratio (AR=33.5) and lift-to-drag ratio (L/D=56) In aeronautics, the aspect ratio of a wing is the ratio of its span to its mean chord. It is equal to the square of the wingspan divided by the wing area. Thus, a long, narrow wing has a high aspect ratio, whereas a short, wide wing ...

  3. Aspect ratio (image) - Wikipedia

    en.wikipedia.org/wiki/Aspect_ratio_(image)

    Aspect ratio (image) The aspect ratio of an image is the ratio of its width to its height. It is expressed as two numbers separated by a colon, width:height. Common aspect ratios are 1.85:1 and 2.40:1 in cinematography, 4:3 and 16:9 in television, and 3:2 in still photography.

  4. Bird wing - Wikipedia

    en.wikipedia.org/wiki/Bird_wing

    Aspect ratio is the ratio of wingspan to the mean of its chord (or the square of the wingspan divided by wing area). Wing loading is the ratio of weight to wing area. Most kinds of bird wings can be grouped into four types, with some falling between two of these types. These types of wings are elliptical wings, high-speed wings, high aspect ...

  5. Aspect ratio - Wikipedia

    en.wikipedia.org/wiki/Aspect_ratio

    The aspect ratio of a geometric shape is the ratio of its sizes in different dimensions. For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter sideā€”the ratio of width to height, [1][2] when the rectangle is oriented as a "landscape". The aspect ratio is most often expressed as two integer numbers ...

  6. Wing configuration - Wikipedia

    en.wikipedia.org/wiki/Wing_configuration

    Wing configuration. The Spitfire wing may be classified as: "a conventional low-wing cantilever monoplane with unswept elliptical wings of moderate aspect ratio and slight dihedral". The wing configuration of a fixed-wing aircraft (including both gliders and powered aeroplanes) is its arrangement of lifting and related surfaces.

  7. Chord (aeronautics) - Wikipedia

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

    The ratio of the length (or span) of a rectangular-planform wing to its chord is known as the aspect ratio, an important indicator of the lift-induced drag the wing will create. [7] (For wings with planforms that are not rectangular, the aspect ratio is calculated as the square of the span divided by the wing planform area.)

  8. Macro photography - Wikipedia

    en.wikipedia.org/wiki/Macro_photography

    Macro photograph of an ant. Macro photograph of a fern sorus using 4:3 aspect ratio. Macro photography (or photomacrography[1][2] or macrography, [3] and sometimes macrophotography[4]) is extreme close-up photography, usually of very small subjects and living organisms like insects, in which the size of the subject in the photograph is greater ...

  9. Panoramic photography - Wikipedia

    en.wikipedia.org/wiki/Panoramic_photography

    Panoramic photography is a technique of photography, using specialized equipment or software, that captures images with horizontally elongated fields of view. It is sometimes known as wide format photography. The term has also been applied to a photograph that is cropped to a relatively wide aspect ratio, like the familiar letterbox format in ...
