ROTOR FOR A WIND TURBINE

摘要

The present invention relates to a rotor for a wind turbine, said rotor having a diameter of 50 metres or more. A blade of said rotor comprises at least two blade sections in the lengthwise direction of said blade, where at least one blade section has a curvature along the blade and relative to a second blade section, where said curvature results in the tip end of said blade being offset (x) relative to the axis of the blade root, where the ratio (x/L) of the offset (x) relative to a distance (L) from the tip end of the blade to the blade root, said distance (L) being measured perpendicular to the plane of the root end of the blade and said offset (x) being measured as the perpendicular offset from the axis of the blade root, is between 0 and 0,1, and that said rotor is with a cone angle ß between 0 and 10 degrees, said cone angle ß being measured between the axis of the blade root and perpendicular to the axis of the main shaft.
