Abstract
A rotor blade, with a suction side and a pressure side, for a wind turbine, having a rotor blade root of a hub region for attaching the rotor blade to a rotor hub, a rotor blade tip, which is arranged on a side, facing away from the rotor blade root, of a tip region, at least one vortex generator, which is arranged between the rotor blade root and the rotor blade tip, wherein the at least one vortex generator comprises swirl elements with a length and a height, which are arranged one next to the other in a longitudinal direction of the rotor blade and are in each case oriented at an angle to a main flow direction of the rotor blade, wherein, in the longitudinal direction of the rotor blade, the swirl elements have a lateral spacing to one another. A variation in the geometry of the swirl elements is realized in a manner dependent on a respective distance between the arrangement of the swirl elements and the rotor blade root.
