Abstract: The present disclosure is directed to methods for joining rotor blade components using thermoplastic welding. The method includes arranging a first thermoplastic component and a second thermoplastic component together at an interface, determining a size of a tolerance gap between the first and second components at the interface, placing a thermoplastic insert between the first and second components at the interface, the insert being larger than the tolerance gap, heating the insert and the first and second components such that the insert begins to flow so as to fill the tolerance gap between the first and second components, applying pressure to the interface such that the insert and the first and second blade components remain substantially in direct contact with each other at the interface, and welding the insert and the first and second components together at the interface, wherein the heat and the applied pressure between the insert and the first and second components at the interface maintain the insert and the first and second substantially in direct contact at the interface during welding.

Abstract: The present disclosure is directed methods for modifying molds of rotor blades of a wind turbine. In certain embodiments, the blade mold is constructed, at least in part, of a thermoplastic material optionally reinforced with a fiber material. In one embodiment, the method includes identifying at least one blade mold addition for the mold of the rotor blade and positioning the blade mold addition at a predetermined location of the mold of the rotor blade. Further, the blade mold addition is constructed, at least in part, of a thermoplastic material. Thus, the method includes applying at least one of heat, pressure, or one or more chemicals at an interface of the blade mold addition and the mold so as to join the blade mold addition to the mold. In further embodiments, the methods described herein are also directed repairing thermoplastic blade molds.

Abstract: The present subject matter directed to a rotor blade assembly for a wind turbine having at least one rotatable aerodynamic surface feature configured thereon. The rotor blade assembly includes a body shell including a pressure side surface and a suction side surface extending between a leading edge and a trailing edge. The aerodynamic surface feature is disposed adjacent to the pressure side surface, the suction side surface, and/or both. In addition, the surface feature may have a generally airfoil-shaped cross section. As such, an actuator can be configured at least partially within an internal volume of the surface feature, the actuator being configured to rotate the surface feature relative to the body shell.

Abstract: A rotor blade assembly for a wind turbine includes a rotor blade having a pressure side, a suction side, a leading edge, and a trailing edge. A vortex generator accessory is mounted to either of the suction side or pressure side and includes a base portion and a protrusion member extending upwardly from the base portion. An attachment layer connects the base portion to the suction or pressure side. The attachment layer has a lower shear modulus than the base portion to allow for shear slippage between the base portion and the underlying suction or pressure side.
