Flap carriers fold spanwise (about chordwise axes) into the wing but are moved down together through pivotal linkage; the flaps are protracted and retracted through pivoting of the carriers relative to each other on spanwise axes. On retraction, the entire assembly fits into the wing so that the flow determining contour thereof remains undisturbed.

Flap arrangement with adjustment devices along the trailing edge of an aircraft wing, having a plurality of wing flaps, comprising: a first flap carrier, pivotably mounted to the wing, on shaft means which extend in chord direction of the wing, said shaft means being slidably mounted in a recess on the underside of the wing, for sliding in spanwise direction, said first carrier thus being provided for pivoting and down extension as well as sliding, in and retraction into the recess in the wing, while undergoing a combined sliding and pivot motion for down extension, the carrier will extend in spanwise direction when folded into the recess; a plurality of further carriers including a second carrier being hinged to said first carrier through a first, spanwise pivot axis when the first carrier is pivoted out of the recess, and a third carrier pivoted to the second carrier by a second pivot axis extending spanwise when the second and third carrier extend down, the plurality of further carriers being respectively pivoted to further chordwise axes on said wing flaps such that when all said wing flaps are in a retracted position the latter chordwise pivot axes are coaxial with said first pivot axis; means for pivoting the further carriers about the spanwise pivot axes for protraction and retraction of the wing flaps; said wing flaps having recesses, said further chordwise axes being established by additional shafts, respectively, sliding in the latter recesses; and the first carrier, when situated in the recess of the wing, causing the wing to offer minimal drag as all of the carriers are now within aerodynamic confines of the wing plus wing flap configuration.
