An adaptive profile edge of an aerodynamic profile, the aerodynamic profile having a body structure including an outside surface disposed along a periphery of the profile edge, an inside surface opposite the outside surface, an upper side and an under side, the profile edge comprising:
- an initial curvature;
- a coating of multifunctional material disposed in a partly distributed manner on the outside surface of the profile edge;
- and wherein upon introduction of an external force to the profile edge the multifunctional material is activated, activation of the multifunctional material causing a structural deformation of the profile edge along its length thereof so as to vary the initial curvature of the first profile edge into a second curvature.
An adaptive profile edge of an aerodynamic profile, the aerodynamic profile having a body structure including an outside surface disposed along a periphery of the profile edge, an inside surface opposite the outside surface, an upper side and an under side, the profile edge comprising:
- an initial curvature;
