Abstract
Adjusting device for landing flaps covering a gap between a landing flap or flaps and a wing proper there being a driven torsion shaft for driving the flaps, whereby particularly a transmission gear is drivingly coupled to the torsion shaft and includes a reducing gear and a gear segment being bidirectionally driven by the gear; a slotted cam is connected to and driven by the segment gear; a pair of levers with scanning elements is operated by the cam on rotation thereof; tension-compression rods are respectively linked to the levers such that the rods are operated in opposite direction; and a pair of elbow levers respectively connect the rods to two wing flaps such that the rods are tension loaded then compression loaded by the aerodynamic forces acting on the wing flaps.
