Aspect Ratio (wing)

Aspect Ratio (wing)

In aerodynamics, the aspect ratio of a wing is essentially the ratio of its length to its breadth (chord). A high aspect ratio indicates long, narrow wings, whereas a low aspect ratio indicates short, stubby wings.

For most wings the length of the chord is not a constant but varies along the wing, so the aspect ratio AR is defined as the square of the wingspan b divided by the area S of the wing planform, which is equal to the length-to-breadth ratio for a constant chord wing. In symbols,

Famous quotes containing the words aspect and/or ratio:

    We do not associate the idea of antiquity with the ocean, nor wonder how it looked a thousand years ago, as we do of the land, for it was equally wild and unfathomable always. The Indians have left no traces on its surface, but it is the same to the civilized man and the savage. The aspect of the shore only has changed.
    Henry David Thoreau (1817–1862)

    People are lucky and unlucky not according to what they get absolutely, but according to the ratio between what they get and what they have been led to expect.
    Samuel Butler (1835–1902)
