ABSTRACT:
The leading edge (12) of an aircraft wing is equipped with a kruger nose which includes a rigid flap (18) and a mechanism (26,28,30,40) ensuring the deployment of the flap in an intermediate landing position (P3) and in a take-off position (P2). The disposition of this mechanism is such that, in the landing position (P3), a slot exists between the flap (18) and the leading edge, whereas this slot disappears in the take-off position (P2). The mechanism preferably includes two connection rods (28,30) connecting a control reversing lever (26) and an intermediate reversing lever (40).
