Abstract

The disclosure relates to a wind turbine rotor blade, including an aerodynamic add-on element comprising a baseplate, the baseplate having an upper side and a bottom side, wherein the aerodynamic add-on element is mounted with the bottom side of the baseplate to an outer surface of the wind turbine rotor blade, at least a section of the bottom side is inclined relative to the outer surface of the wind turbine rotor blade along a downstream direction of an operational wind flow, such that a gap is formed between the at least one section and the outer surface in which a distance between the outer surface and the bottom side increases along the downstream direction, and adhesive is provided in the gap to bond the aerodynamic add-on element to the outer surface of the wind turbine rotor blade. The disclosure also relates to an aerodynamic add-on element.
