Patent ID: 8517315

Claim:
An airfoil of an aircraft with a main wing and at least one aerodynamic body that can be adjusted relative to the main wing transverse to its wingspread direction by means of a drive unit, with said airfoil featuring: carrier parts disposed on the main wing for movably mounting the at least one aerodynamic body on the main wing; at least two connecting devices that are spaced apart from one another in a wingspread direction of the main wing and serve for guiding the aerodynamic body during the adjustment relative to the main wing, wherein said connecting devices support the aerodynamic body and include: a suspension carrier and at least one articulated connection which allows at least one rotational degree of freedom of the aerodynamic body relative to the main wing with a rotational axis that has a directional component transverse to the wingspread direction of the aerodynamic body; and a lateral coupling device for holding and guiding the aerodynamic body relative to the main wing in the wingspread direction during the adjustment thereof, with said lateral coupling device featuring: (i) a coupling connection, (ii) a first coupling joint for coupling a first end of the coupling device to at least one of the main wing, another aircraft component connected to the main wing, and another aerodynamic body, and (iii) a second coupling joint for coupling a second end of the coupling device to one of: the aerodynamic body and another aerodynamic body, wherein 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.
