Described is a wing tip shape for a wing, in particular of aircraft, which wing comprises a profile that extends in the direction of the span of the wing (1), and across said direction of the span of the wing (1) extends from the wing leading edge (8, 6, 10) to the wing trailing edge (7), which profile is delimited by a first skin (11) and a second skin (12), with a winglet (3), arranged on the wing end, which winglet (3) is essentially planar, and with a transition region (2) arranged between the wing (1) and the winglet (3), which transition region (2) extends from a connection (4) on the wing (1) to a connection (5) on the winglet (3). The invention provides for the curvature of the local dihedral to increase in the transition region (2) from a low level or a level of zero at or near the wing intersection (4) in the outboard direction.

L'invention concerne une forme d'extrémité d'aile destinée à une aile, en particulier d'un avion, une telle aile comprenant un profil qui s'étend dans la direction d'envergure de l'aile (1) et à travers ladite direction d'envergure de l'aile (1), du bord d'attaque de l'aile (8, 6, 10) au bord de fuite de l'aile (7), dont le profil est délimité par un premier revêtement (11) et un second revêtement (12) avec une ailette (3) agencée sur l'extrémité de l'aile, cette ailette (3) étant essentiellement planaire, et avec une zone de transition (2) placée entre l'aile (1) et l'ailette (3), une telle zone de transition (2) s'étendant d'un raccordement (4) sur l'aile (1) à un raccordement (5) sur l'ailette (3). L'invention fournit la courbure du dièdre local afin d'augmenter et passer, dans la zone de transition (2), d'un bas niveau ou à un niveau zéro à, ou proche de, l'intersection de l'aile (4) dans la direction extérieure.
