But using the same theory and tests, it was found that a rectangular wing of aspect ratio 6 has only about 5 per cent greater induced drag then than of ix an elliptical.

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. Aspect ratio and other features of the planform are often used to predict the aer… WebbHigh aspect-ratio, long-endurance aircraft require di erent design modeling from those with traditional moderate aspect ratios.
