WebbFrom theoretical considerations and from pressure distrubition tests, it can be dem nstrated that the ideal wing form is the elliptical because it has the smallest induced drag. 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… WebbFigure .1: Aircraft Wing Daniel P Raymer[1] has described the various aerodynamic considerations in the design of aircrafts.
