Beschreibung
Zusammenfassung:	A swept aircraft wing includes a leading airfoil element and a trailing airfoil element. At least one full-span slot is defined by the wing during at least one transonic condition of the wing. The full-span slot allows a portion of the air flowing along the lower surface of the leading airfoil element to split and flow over the upper surface of the trailing airfoil element so as to achieve a performance improvement in the transonic condition. L'invention porte sur une aile d'aéronef balayée comprenant un élément de surface portante avant et un élément de surface portante arrière. Au moins une fente complètement étendue est définie par l'aile pendant au moins une condition transsonique de l'aile. Cette fente complètement étendue permet à une partie de l'air circulant le long de la surface inférieure de l'élément de surface portante avant afin de se diviser et de circuler au-dessus de la surface supérieure de l'élément de surface portante arrière afin d'améliorer la performance de la condition transsonique.
