摘要： A method is for controlling the quality of a wind turbine rotor blade. The method includes: manufacturing of a wind turbine rotor blade at a manufacturing site, placing the wind turbine rotor blade on a support at the manufacturing site, applying a dynamic load to the wind turbine rotor blade while the wind turbine rotor blade is placed on the support in order to excite a vibration of the wind turbine rotor blade, detecting the vibration of the wind turbine rotor blade, determining an eigenfrequency of the wind turbine rotor blade based on the detected vibration, comparing the determined eigenfrequency with an expected eigenfrequency of the wind turbine rotor blade and evaluating the quality of the wind turbine rotor blade based on the results of the comparison.

摘要： The invention is directed to a rotor blade for a wind turbine. The rotor blade has a rotor blade main body which delimits a rotor blade cavity. A rotor blade tip is connected fixedly to the rotor blade main body. The rotor blade tip has a drainage bore which is coupled fluidically to the rotor blade cavity and which is open toward a suction side surface of the rotor blade tip, so that, via the drainage bore, fluid from the rotor blade cavity drains to the outside at the suction side surface of the rotor blade tip. The invention is also directed to a rotor blade tip.

摘要： A vortex generator defines a longitudinal direction and has two fins, which are each arranged at an angle in relation to the longitudinal direction and extend over a first length in the longitudinal direction, and a base, which connects the two fins to each other, the base having a width and extending over a second length in the longitudinal direction, wherein the second length is less than the first length over the entire width of the base.

摘要： 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.
