Abstract
An actuation apparatus for a control flap which is disposed on the trailing edge of the wing of an aircraft and which can be displaced between a stowed position and an extended position, in which it is displaced rearwardly relative to the trailing edge of the wing and angled downwardly relative to the wing plane; and corresponding intermediate positions. The actuation apparatus has a pyramid mechanism arrangement connected, on the one hand, to the load-bearing structure of the wing and, on the other hand, to the control flap, with at least one virtual axis which lies, in particular, at a finite distance from the plane of the wing profile and relative to which the control flap can be displaced.
Claims17
Actuation apparatus for moving two structural parts relative to each other between a stowed position and an extended position with a rotational and a translational component,
- wherein the actuation apparatus comprises at least one adjustment unit, which is connected at a first end to the load-bearing structure of a wing and at a second end to a control flap, with at least one virtual axis of rotation lying at a finite distance from a plane of the wing, and driving means, with respect to which the structural parts can be displaced in relation to each other,
- further wherein the actuation apparatus comprises a pyramid mechanism arrangement which changes the distance of the control flap from a trailing edge of the wing, and an adjustment device, which is mechanically coupled to the pyramid mechanism arrangement and adjusts the angle of the control flap.
