Abstract

A rotor blade of a wind turbine, having a rotor blade length, a rotor blade depth extending over the rotor blade length, a rotor blade thickness extending over the rotor blade length, and a thickness of a trailing edge of the rotor blade extending over the rotor blade length, wherein, in a region of the rotor blade length, the rotor blade simultaneously has a splitter plate that has a predetermined length and a Gurney flap that has a predetermined height, wherein a ratio of the predetermined height of the Gurney flap to the predetermined length of the splitter plate at a particular position in the direction of the rotor blade length is selected in such a manner that a threshold value that decreases with a relative profile thickness, which is defined as a ratio of the rotor blade thickness to the rotor blade depth, is not reached.
