Abstract
A method of guiding lightning to a lightning receptor of a rotor blade for a wind turbine, wherein the method includes the following steps: Generating a vortex of airflow by means of a vortex generator, the vortex generator being located at the surface of the rotor blade; attracting the lightning by the vortex; guiding the lightning to the lightning receptor is provided. Furthermore, the invention relates to a rotor blade for a wind turbine, wherein the rotor blade comprises a vortex generator for generating a vortex of airflow, the vortex generator being located at the surface of the rotor blade, and a lightning receptor for receiving an electrical current from the lightning. The vortex generator and the lightning receptor are arranged such with regard to each other that the lightning is guided to the lightning receptor by the vortex which is generated by the vortex generator.
