Wing of an aircraft having a mainplane (20), which has an upper face (22), a lower face (23) and an aerodynamical Iy shaped area (21), and having an additional airfoil (10) which is articulated on the mainplane (20) and can be extended from a retracted state with a slot area (9) being opened between the mainplane (20) and the additional airfoil (10) and having a variable-position slot-varying apparatus (16) which is arranged on the lower face, forms a part of the aerodynamic profile of the additional airfoil (10) or mainplane (20) when the additional airfoil (10) is extended, and at least partially covers the slot area (9) between the mainplane (20) and the additional airfoil (10) on the lower face when the additional airfoil (10) is in the retracted state. The slot -varying apparatus (16) can be varied between a curved configuration, in which it forms a part of the aerodynamic profile of the additional airfoil (10) or mainplane (20) when the additional airfoil (10) is extended, and an extended configuration, in which it at least partially covers the slot area (9) between the mainplane (20) and the additional airfoil (10) on the lower face when the additional airfoil (10) is in the retracted state.

La présente invention concerne une aile d'aéronef comportant un plan principal (20), comprenant une face supérieure (22), une face inférieure (23) et une zone de forme aérodynamique (21), et présentant un profil d'aile additionnel (10) articulé sur le plan principal (20) et capable de se déployer depuis un état rétracté par l'ouverture d'une zone de fente (9) entre le plan principal (20) et le profil d'aile additionnel (10) et comprenant un appareil de variation de fente à position variable (16) disposé sur la face inférieure, formant une partie du profil aérodynamique du profil d'aile additionnel (10) ou du plan principal (20) lorsque le profil d'aile additionnel (10) est déployée, et recouvrant au moins en partie la zone de fente (9) entre le plan principal (20) et le profil d'aile additionnel (10) sur la surface intérieure lorsque le profil d'aile additionnel (10) se trouve en l'état rétracté. L'appareil de variation de fente (16) peut être commuté entre une configuration courbe, dans laquelle il forme une partie du profil aérodynamique du profil d'aile additionnel (10) ou du plan principal (20) lorsque le profil d'aile additionnel (10) est déployé, et une configuration déployée, dans laquelle il recouvre au moins en partie la zone de fente (9) entre le plan principal (20) et le profil d'aile additionnel (10) sur la face inférieure lorsque le profil d'aile additionnel (10) se trouve en l'état rétracté.
