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,
