Abstract: A lateral coupling device for holding and guiding at least one aerodynamic body relative to the main wing in its wingspread direction during the adjustment thereof features: a coupling connection, a first coupling joint for coupling a first end of the coupling connection to the main wing or an aircraft component connected thereto or another aerodynamic body, as well as a second coupling joint for coupling the second end of the coupling connection to the aerodynamic body, where the lateral coupling device has a total of five degrees of freedom and allows an adjusting motion of the aerodynamic body relative to the main wing transverse to the wingspread direction thereof.

Abstract: An aircraft wing trailing edge control surface including a trailing edge flap adjustable to different positions, a sealing flap on the upper side between the wing and the flap, and a ventilation flap on the underside between the wing and the flap. The flap is adjustable downward through positive positions and upward through negative positions. The wing profile is closed on the upper side by the sealing flap and the underside by the ventilation flap when the flap is used as a control flap and adjusted between negative and low positive positions. The ventilation flap releases air flow from the wing underside to the upper side of the flap and the sealing flap is retracted to release an outflow of air from the upper side of the flap when the flap is used for increasing lift and the flap is adjusted between low and high positive positions.

Abstract: A lift-augmenting leading edge flap for a carrying wing of an aircraft, wherein the flap comprises an essentially rigid main body which makes a transition from the first side to the second side of the wing the flap being adjustable by a retention- and actuation mechanism coupled between the flap and wing box, between a first, retracted, position and a second, extended, position, wherein the first transition region of the flap is slidable to rest in each position essentially free of any gap, against the first skin of the wing box or against the wing end cover, in relation to the wing end cover.
