1. A deformable aerodynamic profiled member comprising:

  • a front profile area;

    a rear profile area;

    shells which bound the profiled member on a pressure side and on a suction side, which shells converge in a rear profile edge; and

    deforming means for varying a curvature of said profiled member by changing length of at least one of said shells in a desired direction;

    wherein,said deforming means comprises at least one d33 piezo actuator mounted on said at least one shell; and

    said at least one piezo actuator is arranged on said at least one shell with an orientation such that a change of length of said at least one piezo actuator cause a change of length in a plane of said at least one shell in said desired direction, and a corresponding deformation of said profile, when said at least one actuator is acted upon by electricity.
