Rotor blades of rotors of wind power plants, wind power plants and methods for improving the efficiency of rotors of wind power plants

摘要

The present invention relates to a rotor blade having a profile depth adjusted between a rotor blade trailing edge and a rotor blade leading edge, and a rotor blade trailing edge extending over the rotor blade length between the rotor blade root and the rotor blade. In order to increase efficiency, at least one profile element with a continuous profile section can be attached on the area of the rotor blade trailing edge or within the region of the rotor blade trailing edge, for changing the profile depth of the rotor blade, The extension of the profile section beyond is determined by the load-dependent standardized dimensioning of the profile depth of the rotor blades and the load level adjusted at the installation site of the wind turbine.
