Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. An elliptical wing is a wing planform shape that minimizes induced drag. Elliptical taper shortens the chord near the wingtips in such a way that all parts of the wing experience equivalent downwash, and lift at the wing tips is essentially zero, improving aerodynamic efficiency due to a greater Oswald efficiency number in the induced drag equation. The elliptical wing was first used on aircraft in the 1930s, but has only seen limited use.
