    Abstract: Rotor blade assemblies for wind turbines are provided. The rotor blade assembly includes a rotor blade having exterior surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge each extending between a tip and a root. The rotor blade further defines a span and a chord. The rotor blade assembly further includes at least one vortex generator configured on at least one of the suction side or the pressure side of the rotor blade, the at least one vortex generator having an aspect ratio between approximately 4 and approximately 10. In another embodiments, the rotor blade assembly further includes at least one vortex generator configured on at least one of the suction side or the pressure side of the rotor blade, the at least one vortex generator having a length between approximately 4% and approximately 20% of a local chord.

    Abstract: In one aspect, a rotor blade assembly for a wind turbine may generally include a rotor blade extending lengthwise between a root and a tip. The rotor blade may include a pressure side and a suction side extending between a leading edge and a trailing edge. Additionally, the rotor blade assembly may include a chord extender having an attachment portion coupled to at least of the pressure side or the suction side and an extension portion extending outwardly from the attachment portion beyond the trailing edge. The extension portion may extend chordwise between a first end disposed adjacent to the trailing edge and a second end disposed opposite the first end. The extension portion may include a surface defined between the first and second ends. The extension portion may further include at least one stiffening rib projecting outwardly from the surface.

    Abstract: A blade insert for coupling a first blade segment to a second blade segment is disclosed. The blade insert may include an aerodynamic body extending between a first end configured to be coupled to the first blade segment and a second end configured to be coupled to the second blade segment. The aerodynamic body may include a pressure side and a suction side extending between a leading edge and a trailing edge. In addition, the aerodynamic body may define a chord, wherein the chord at the first end is substantially equal to the chord at the second end.

    Abstract: Rotor blade assemblies for wind turbines are provided. In one embodiment, a rotor blade assembly includes a rotor blade, and a plurality of vortex generators configured on at least one of a suction side or a pressure side and disposed within an inboard area of the rotor blade. The plurality of vortex generators include a row of vortex generators extending in a generally span-wise direction, the row comprising a first portion of vortex generators and a second portion of vortex generators, the second portion of vortex generators spaced apart from the first portion of vortex generators in the span-wise direction. Each first portion vortex generator is disposed at a first chord-wise location, and each second portion vortex generator is disposed at a second chord-wise location different from the first chord-wise location.
