Abstract (en)
[origin: WO2008141763A2] The invention relates to a supporting arm for the blades of wind turbines with a vertical rotational axis, said arm being situated substantially along a radius between the hub (1) or the bearing organ of the turbine and each of the blades (3) that lie at a corresponding distance from said hub. The cross-section (2s) of the arm is substantially symmetrical about a horizontal axis and is formed by a front convex surface (2a) and a rear concave surface (2b) according to the rotational direction (R) of the rotor. Said cross-section (2s), whether it be the concave or the convex surface, takes the form of an arc, a parabola, a nose cone or a leading edge of a blade profile.
