Abstract
A segmented flap having a variable curvature for an airplane wind. The flap includes segments arranged to be angularly adjustable in relation to each other and in relation to the wing and at least an articulating mechanism having a first link arm and a second link arm. The first link arm is arranged at an edge of the wing. The second link arm is rotatably attached to the first link arm by a first shaft. The first link arm is provided with an elongated first channel that extends at the side of and in a determined angle intersects an elongated second channel arranged in the second link arm. A guide rail is arranged in a direction transversal to the two channels and located in an opening defined by the channels where they intersect each other. A plurality of rods connect the angular legs that define an angle formed by the two link arms and which are rotatably attached to each other and to the link arms and which have variable lengths, so that the rods together with each other form a polygon curve, such that a displacement of the guide rail in the channels of the link arms determines the curvature of the polygon curve, whereby the curvature of the flap is determined as each rod being p…
