Abstract:
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.
