Rotor blade of a rotor of a wind turbine, wind turbine and method for improving the efficiency of a rotor of a wind turbine

摘要

The present invention relates to a rotor blade which has a rotor blade trailing edge extending between the rotor blade root and the rotor blade over a rotor blade length and also a tread depth which is established between the rotor blade trailing edge and the rotor blade leading edge. To increase the efficiency, at least one profile element with a continuous profile section for changing the tread depth of the rotor blade can be attached to or in the region of the rotor blade trailing edge, the extension of the profile section beyond the rotor blade trailing edge depending on a normalized load-dependent dimensioning of the tread depth of the rotor blade and on a Site of wind turbine setting load level determined.
