A rear-edge flap is held on an aircraft wing by means of two pantograph-like guide systems carrying swivel heads on which the flap is pivoted. Control arms extend from the guide systems to cause the flap to be pivoted and the guide systems extend the flap. Details concerning bearings and kinematics

A rear-edge flap is held on an aircraft wing by means of two pantograph-like guide systems carrying swivel heads on which the flap is pivoted. Control arms extend from the guide systems to cause the flap to be pivoted and the guide systems extend the flap. Details concerning bearings and kinematics are disclosed. Application of the invention to all rear flaps of two aircraft wings is described.

In an airfoil, a flap, an actuating mechanism for moving the flap, comprising: two pantograph guide systems each being pivotally secured to the airfoil at points spaced along the span of the airfoil, each guide system having two branches pivotally linked to a head, there being two heads accordingly; means for each of the guide systems, for pivotally linking respectively the heads to the flap for pivoting on approximately horizontal axes, the axes extending transversely to a direction of the flap movement, said means for respectively pivotally linking the heads to the flap including essentially vertical pins accordingly, one of the pins positively permitting lateral play to a larger extent than the other pin; two control rods for each of the guide systems respectively extending from the two branches of the respective guide system and being pivotally linked thereto as well as pivotally linked to the flap at points in each instance being spaced from the respective one of said axes so that, upon expansion of the guide link for extension of the flap, the flap is pivotally actuated for pivoting on said horizontal axes; and drive means connected for extending and retracting the guide systems.
