Abstract: A rotor blade assembly of a wind turbine includes a rotor blade having an aerodynamic body with an inboard region and an outboard region. The inboard and outboard regions define a pressure side, a suction side, a leading edge, and a trailing edge. The inboard region includes a blade root, whereas the outboard region includes a blade tip. The rotor blade also defines a chord and a span. Further, the inboard region includes a transitional region of the rotor blade that includes a maximum chord. Moreover, a unitless first derivative of the chord with respect to the span of the rotor blade in the transitional region ranges from about −0.10 to about 0.10 from the maximum chord over about 15% of the span of the rotor blade. In addition, the unitless first derivative of the chord with respect to the span a slope of a change in the chord in is greater than about −0.03 at an inflection point of the chord in the outboard region.

Abstract: A method to reduce noise and vibration between separate blade segments of a jointed wind turbine rotor blade includes determining an actual offset at a chord-wise joint line between the shell members of the first and second blade segments at a load condition on the jointed wind turbine rotor blade, wherein the offset is any one or combination of a flap-wise offset, a twist-wise offset, or a yawl-wise offset. The method defines a modified configuration of the joint structure at a no-load condition on the wind turbine rotor blade that compensates at least partially for the actual offset at the load condition, and the first and second blade segments are connected with the modified configuration of the joint structure.

Abstract: A rotor blade assembly for a wind turbine includes a rotor blade having surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge extending between a blade tip and a blade root. The rotor blade assembly also includes at least one noise reducer adjacent to the trailing edge. The noise reducer(s) includes at least one serration extending beyond the trailing edge in a chord-wise direction of the rotor blade. The serration(s) also includes a suction side surface and a pressure side surface. The suction side surface defines a first radius of curvature in the chord-wise direction and the pressure side surface defines a second radius of curvature in the chord-wise direction. Further, the first radius of curvature may be larger than the second radius of curvature such that the suction side surface is flatter than the pressure side surface or vice versa.

Abstract: The present disclosure is directed to vortex generators for wind turbine rotor blades having noise-reducing features. For example, the vortex generators are mounted within a laminar flow region on either the pressure side or the suction side of the rotor blade and have a base portion with at least one airflow modifying element extending therefrom. The base portion has a leading edge and a trailing edge extending in a first direction. Further, the base portion includes one or more edge features formed within either or both of the leading or trailing edges. Moreover, the edge features are non-parallel with respect to the first direction so as to reduce laminar boundary layer instability noise.

Abstract: A computer-implemented method of operating a wind turbine park including operating wind turbines includes recording a plurality of sound pressure measurements of the wind turbine park, thereby generating a sound recording. The method also includes calculating values for a plurality of acoustic features associated with the sound recording.
