The invention relates to a fore flap disposed on the wing of an aircraft, wherein the wing comprises a main wing (24) having an upper planking (21), a lower planking (22), and a profile nose (23), and the fore flap (12) is on the front side of the main wing (24) and has a profile nose (10) oriented forward and an end edge (11) facing the main wing (24) and oriented rearward, and can be extended in order to increase lift by increasing the curvature and extent of the wing profile in the depth direction of the wing, from a retracted cruise flight position (I) in which the fore flap (12) contacts the front side of the main wing (24) and extends the profile thereof into a shape suitable for cruise flight, wherein the end edge (11) of the fore flap (12) contacts the main wing (24) in a first, partially extended position (II), and having the end edge (11) at a distance from the profile nose (23) of the main wing in a second, further extended position (IM), exposing high-energy air from the bottom side of the fore flap (12) to the top side (21) of the gap (14) leading the main wing (24). The fore flap (12) comprises a main body (6) and an end edge part (2) facing the main wing (24) and displaceable at an angle in the wing span direction of the fore flap (12) relative to the main body (6), and on which the end edge (11) of the fore flap (12) is provided, and which is acted on by means of a device (4; 8; 9) generating a contact force for contacting the end edge (11) of the fore flap against the profile nose (23) of the main wing (24). |
