An elliptical wing is a wing planform shape, first seen on aircraft in the l930s, which 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. 2, record 1, English, - elliptical%20wing

Une aile elliptique est une forme d'aile apparue dans les années 1930 pour diminuer la traînée aérodynamique. La forme elliptique diminue la courbure de l'aile à son extrémité entraînant un écoulement de l'air homogène sur toute la longueur et une force de poussée proche de zéro à son extrémité. Le tout améliorant l'efficacité aérodynamique. 3, record 1, French, - aile%20elliptique
