Abstract
A deformable aerodynamic profiled member has a front profile area and a rear profile area in the outflow area. It is bounded by shells on the pressure side and/or on the suction side, converging in a rear profile edge (6). D33 piezo actuators are provided in at least some locations for deformation of the profiled member. The piezo actuators are aligned such that their length changes essentially in the direction of the planes of the shells when acted upon by electricity.

-11. (canceled)
A deformable aerodynamic profiled member comprising:
- a front profile area;
- a rear profile area in an outflow region relative to a flow direction;
- shells which bound the profiled element on a pressure side and on a suction side, which shells converge in a rear profile edge;
- and
- d33 piezo actuators for deforming profiled members;
- wherein said piezo actuators are arranged on said profiled member with an orientation such that their length changes substantially in the direction of the planes of the shells when acted upon by electricity.
