Abstract
A flap system for an aircraft comprises a wing structure, a trailing-edge and an attachment unit for movably coupling the trailing-edge movable to the wing structure. The attachment unit comprises an attachment mechanism and a cover element which at least partly encloses the attachment mechanism. The attachment unit comprises a drive element which is configured to move the cover element along an aerodynamic outer surface of a skin section of the wing structure between a first position and a second position, wherein the movement of the cover element along the aerodynamic outer surface is defined by a translational movement of the cover element relative to the skin section.

A flap system for an aircraft comprising:
- a wing structure having a skin section with an aerodynamic outer surface;
- a trailing-edge unit comprising at least one trailing-edge movable configured to move between a retracted position and an extended position;
- and
- an attachment unit for movably coupling the at least one trailing-edge movable to the wing structure;
- wherein the attachment unit comprises an attachment mechanism and a cover element which at least partly encloses the attachment mechanism;
- wherein the attachment unit further comprises a drive element configured to move the cover element along the aerodynamic outer surface of the skin section between a first position and a second position;
- wherein a movement of the cover element along the aerodynamic outer surface of the skin section between the first position and the second position is defined by a translational movement of the cover element relative to the skin section between the first position and the second position.
A method of operating a flap fairing at an aircraft wing, the method comprising:
- activating a drive element which is coupled to a wing structure of the aircraft wing, wherein the wing structure comprises a skin section with an aerodynamic outer surface;
- moving, by the drive element, at least one trailing-edge movable coupled to the drive element via an attachment mechanism, such that the at least one trailing-edge movable is moved from a retracted position to an extended position;
- and,
- moving, by the drive element, the flap fairing which at least partly encloses the attachment mechanism,
- wherein moving the flap fairing comprises moving the flap fairing along the aerodynamic outer surface of the skin section between a first position and a second position, and
- wherein a movement of the flap fairing between the first position and the second position is defined by a translational movement of the flap fairing relative to the skin section between the first position and the second position.
