Abstract
A wind turbine rotor blade is provided including an inboard region and an outboard region including a spanwise section associated with the development of an unstable aeroelastic mode. The disclosed rotor blade includes a leading-edge corrective mass arranged within the spanwise section, which leading-edge corrective mass is adapted to move the center of mass of the spanwise section towards the leading edge in order to suppress the development of an unstable aeroelastic mode. A method of manufacturing a wind turbine rotor blade is also provided.
Claims15
A wind turbine rotor blade comprising:
- an inboard region:
- an outboard region including a spanwise section associated with the development of an unstable aeroelastic mode
- wherein a leading-edge corrective mass arranged within the spanwise section, which leading-edge corrective mass is configured to move the center of mass of the spanwise section towards the leading edge in order to suppress the development of an unstable aeroelastic mode.
The wind turbine rotor blade according to clown 1, wherein the leading-edge corrective mass comprises a material with a density of at least 10 g/cm3.
A method of manufacturing a wind turbine rotor blade, which method comprises:
- identifying a spanwise section associated with the development of an unstable aeroelastic mode in an outboard region of the rotor blade;
- determining the properties and position of a leading-edge corrective mass that will suppress the development of an unstable aeroelastic mode in that spanwise section;
- providing such a leading-edge corrective mass;
- and
- arranging the leading-edge corrective mass within that spanwise section.
