ABSTRACT:
In an aerofoil profile with variable profile adaptation, a rib structure of the aerofoil profile is provided which has rigid regions and flexible regions. The flexible region of a rib has at least three rib elements. The rib elements are articulated to one another in kinematic chain arrangement. Driving means are provided for the introduction of force into a movable part of the flexible region of the rib structure, whereby the movement of at least one other rib element may be activated by a stimulated movement of the rib element.
