Patent ID: 7861978

Claim:
A drive and guidance apparatus for a trailing-edge flap which is arranged on an aircraft mainplane, comprising a six-element guide chain having seven rotating joints and one or more shafts; wherein the guide chain is a six-element-seven rotating joint Watt-I chain, the Watt-I chain comprising a first coupling element, which is mounted via a crank that is connected to the aircraft mainplane such that the crank can rotate, the first coupling element arranged between the crank and the trailing-edge flap, the first coupling element in turn being connected to the trailing-edge flap and to a second coupling element such that the first coupling element can rotate, the second coupling element is mounted on the aircraft mainplane such that the second coupling element can rotate, with the second coupling element being connected to the trailing-edge flap via an oscillating support, wherein the crank is arranged in such a manner that the rotation direction of the crank for extension of the trailing-edge flap corresponds to the rotation direction of the crank for the trailing-edge flap of a starboard wing of the mainplane, with the rotation direction of the crank for the trailing-edge flap of the starboard wing being counterclockwise when viewed from the aircraft fuselage.
