WebThe chord of any circle is an important term. It is defined as the line segment joining any two points on the circumference of the circle, not passing through its centre. Therefore, … WebAn 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 has a low aspect ratio. [1] WebMEAN AERODYNAMIC CHORD MAC is essentially an average chord of a lifting surface; in other words, it is the chord-weighted average chord length of the wing, defined as (1) where S is a wing area, b is a wing span, and c is a chord length. MAC can be found for any lifting surfaces, including the horizontal and vertical stabilizers. marley oswalt ae7
