Lateral coupling device for holding and guiding at least one aerodynamic body in relation to the main wing of an aircraft, wing and aircraft comprising the same

Abstract

A lateral coupling device (L) for holding and guiding at least one aerodynamic body in relation to the main wing in the span direction (S) thereof when the latter is adjusted comprises the following: a coupling link (L3), a first coupling connection (L1) for coupling a first end of the coupling link to the main wing or an aircraft component connected therewith or an additional aerodynamic body and a second coupling connection (L2) for coupling a second end of the coupling link to the aerodynamic body (B), the lateral coupling device (L) having a total of five degrees of freedom and allowing an adjusting movement of the aerodynamic body in relation to the main wing (1) at a right angle to the span direction (S) thereof.

Description

technical field [0001] The invention relates to a transverse coupling for holding and guiding at least one aerodynamic surrounding fluid relative to a main wing of an aircraft, a wing and an aircraft with such a transverse coupling. Background technique [0002] In the known high-lift systems of modern commercial aircraft and transport aircraft, especially in such aircraft with a high take-off weight, the streamlined flaps provided as high-lift flaps, for example on the trailing edges of the wings, pass through A plurality of drive locations is movably connected to the airfoil. To actuate the flaps, the torsion shaft is rotated, for example, by a central flap drive arranged in the aircraft, and this rotation is transmitted via a coupling component to an adjustment device for adjusting the streamlined flaps. The streamlined flap suspension guides the landing flap load into the aircraft structure through the fixed bearing suspension, the floating bearing suspension and the la...

Problems solved by technology

[0003] The introduction of transverse loads on the fixed-bearing suspension by bending, especially when the axis of rotation of the landing flap is at a greater distance from the underside of the wing, requires a wider fixed-bearing suspension, which results in a high weight and aerodynamically unfavorable solutions (wider fairings)

Furthermore, in aircraft with inner and outer landing flaps and differently inclined landing flap rotation axes by means of fixed bearing suspensions, overlapping occurs when the two landing flaps move in the area of ​​the separated position, which increases the The complexity of the seal between the flaps
