Abstract
A rotor blade having a rotor blade trailing edge which extends between a rotor blade root and a rotor blade tip over a rotor blade length, and having a profile depth which is established between the rotor blade trailing edge and a rotor blade leading edge. For the purpose of improving efficiency, at least one profile element having a continuous profile section, for the purpose of changing the profile depth of the rotor blade, is able to be attached at or in the region of the rotor blade trailing edge, wherein the extension of the profile section beyond the rotor blade trailing edge is determined in a manner dependent on a standardized load-dependent dimensioning of the profile depth of the rotor blade and a load level which is established at an erection location of the wind turbine.
