1. An airfoil article including a composite skin, the composite skin having a first surface and a second surface opposite to said first surface, the composite skin forming a leading edge and adapted to during use be subjected to an airflow meeting the leading edge at stagnation points, where the airflow is divided into a first and second airflow, and at which stagnation points the local velocity of the airflow is essentially zero, the leading edge comprising:
an elongated member comprising an electrically conductive material, the elongated member having an inner surface and an outer surface opposite to said inner surface, wherein the outer surface of said elongated member is arranged flush with the first surface of the composite skin such that an essentially smooth aerodynamic surface of the leading edge is formed, the elongated member has an extension in a length direction being essentially parallel with an imaginary line intersecting with the stagnation points and a width extending in a chord wise direction at least covering the stagnation points of low angle of attack and the stagnation points of high angle of attack and the area there between, and wherein the elongated member is adapted to serve as an erosion protection of the leading edge and constitutes an electrode of a plasma generating system. |
