The invention relates to a vane having a regulating flap (1) that can be moved between a retracted position and an extended position and a gap covering device (10) having an adjusting lever (13) and a gap covering flap (11) arranged thereon, having a flow surface (11a), .cndot. wherein the adjusting lever (13) having the gap covering flap (11) is prestressed by a prestressing device (20) into a first position in which the gap covering flap (11) is located in the interior (B) of the vane (F), and .cndot. wherein the regulating flap (1) and the adjusting lever (13) having the gap covering flap (11) are coupled mechanically such that when the regulating flap (1) moves into the retracted position thereof, the adjusting lever (1) moves into a second position against the prestress produced by the prestressing device (20), and .cndot. wherein the flow surface (11a) of the gap covering flap (11) in the second position of the adjusting lever (13) runs between the top side (2) of the retracted regulating flap (1) and the vane flow surface (7).

L'invention concerne un aile possédant un volet de réglage (1) pouvant se déplacer entre une position rentrée et une position sortie et un dispositif obturateur de fente (10) avec un levier de positionnement (13) et un volet obturateur de fente (11) monté sur ce dernier avec une surface supérieure d'écoulement (11a). Le levier de positionnement (13) avec le volet obturateur de fente (11), à l'aide d'un dispositif de précontrainte (20), est précontraint dans une première position, où le volet obturateur de fente (11) se trouve à l'intérieur (B) de l'aile (F). Le volet de réglage (1) et le levier de positionnement (13) avec le volet obturateur de fente (11) sont couplés mécaniquement de telle sorte qu'en cas de mouvement du volet de réglage (1) vers sa position rentrée, il se produit un mouvement du levier de positionnement (13) vers une deuxième position à l'encontre de la précontrainte exercée par le dispositif de précontrainte (20). Lorsque le levier de positionnement (13) se trouve dans la deuxième position, la surface supérieure d'écoulement (11a) du volet obturateur de fente (11) se situe entre la face supérieure (2) du volet de réglage (1) rentré et la surface supérieure d'écoulement (7) de l'aile.
