A variable wing section having an adjustable profile shape extending in the wing-span direction, includes a plurality of torsion boxes, which are positioned in the longitudinal direction, are torsionally stiff about the wing-span direction, and are each constituted of a first wing skin, a second wing skin opposite to it, and at least one spar. The variable wing section includes at least one vertebra, which has a transmission element that is connected to the first wing skin by a pendulum joint in order to compensate for a relative movement between the first wing skin and the at least one vertebra, and which has a vertically spaced-apart point of connection to a drive chord, the length of which may be changed, using a control command. The length of the drive chord is changed as a function of a control signal, and the at least one vertebra is rotated about the wing-span direction, so that the shape of the torsion boxes, and thus the profile shape, are changed in a predetermined manner.

Mechanism for at least regionally adjusting the curvature of airfoil wings

A fluid actuating drive for relative translational movement of first and second structural parts has a housing filled with a pressurizing medium, which in its longitudinal direction, runs along a gap that separates the structural parts, and is connected therewith. The width of the gap is dependant upon the relative position of opposing side walls of the housing, which side walls can be moved against one another with a pressurizing agent for the relative movement of the structure, where the side walls are alternately connected to the first and second structural part across the gap.
