An aerodynamic flap (1) having a joint apparatus in order to form an axis of rotation for rotatable mounting of the aerodynamic flap (1) on a wing part (10) or structure part having a front flap part (7), which is located in front of the axis of rotation, seen in the flow direction (S), when the flap (1) is correctly coupled to the wing part (10), which flap part (7) has a front edge line, and having a rear flap part (9), which is located behind the axis of rotation, wherein a plurality of lengthening parts (13), which are distributed over the span of the flap (1), are arranged on the front flap part (7), the ends of which lengthening parts (13) project as exposed parts beyond the front edge line of the flap (1) seen from the axis of rotation, wherein the lengthening parts (13) are rigid and arranged on the flap (1) such that a surface of the lengthening parts (13), together with the upper face or the lower face of the flap (1), forms an aerodynamically uniform surface, and such that the exposed ends of the lengthening parts (13) are directed at an angle to the flow and in the opposite direction to the flow in order to produce vortices when the flap (1) is deflected, and are located below the boundary layer of the wing when the flap (1) is in a neutral position; as well as a wing having an aerodynamic flap (1) such as this. |
