Abstract
A rotor blade assembly for a wind turbine is presented. The rotor blade assembly includes a rotor blade having a surface, where the surface of the rotor blade includes an inclined groove. The rotor blade assembly further includes at least one add-on element mounted on the surface of the rotor blade via a bonding interface downstream of the inclined groove such that particulate matter in an airflow upstream of the at least one add-on element is deflected away from the bonding interface between the surface of the rotor blade and the at least one add-on element. The wind turbine having the rotor blade assembly is also presented.
Claims12
A rotor blade assembly for a wind turbine, comprising:
- a rotor blade comprising a leading edge and a surface, wherein the surface of the rotor blade comprises an inclined groove formed into and recessed within the surface, the inclined groove being a one-sided groove having only one groove edge, the surface defining an arcuate shape extending between the leading edge and the groove edge in a chordwise direction;
- and
- at least one add-on element mounted on the surface of the rotor blade via a bonding interface, the at least one add-on element being spaced apart from and downstream of the inclined groove such that particulate matter in an airflow upstream of the at least one add-on element is deflected away from the bonding interface between the surface of the rotor blade and the at least one add-on element.
A wind turbine, comprising:
- a tower;
- a rotor hub mounted on the tower;
- and
- a plurality of rotor blade assemblies mounted in the rotor hub, wherein one or more of the plurality of rotor blade assemblies comprise:
- a rotor blade comprising a leading edge and a surface, wherein the surface of the rotor blade comprises an inclined groove formed into and recessed within the surface, the inclined groove being a one-sided groove having only one groove edge, the surface defining an arcuate shape extending between the leading edge and the groove edge in a chordwise direction;
- and
- at least one add-on element mounted on the surface of the rotor blade via a bonding interface, the at least one add-on element being spaced apart from and downstream of the inclined groove such that particulate matter in an airflow upstream of the at least one add-on element is deflected away from the bonding interface between the surface of the rotor blade and the at least one add-on element.
