Abstract: The present disclosure is directed to a pre-formed, continuous structural component for use in assembling a modular rotor blade for a wind turbine. Further, the structural component provides support to the modular rotor blade during operation. The pre-formed structural component includes a root portion and a body portion. The root portion is configured for mounting the structural component to a blade root section of the rotor blade. The body portion is configured to extend in a generally span-wise direction. Further, the body portion defines a predetermined cross-section having a flatback portion with a first end and a second end. In addition, the first and second ends each have a flange extending perpendicularly therefrom. Thus, each flange defines a mounting surface for one or more blade segments.

Abstract: A rotor blade for a wind turbine is disclosed. The rotor blade may generally include a shell having a pressure side and a suction side. The shell may define an outer surface along the pressure and suction sides over which an airflow travels. The rotor blade may also include a spoiler having a fixed end and a free end. The fixed end is connected to the outer surface so as to enable a hinge action, such as a living hinge. The free end includes a top flange and a bottom flange configured to engage opposite sides of the shell and is pivotal relative to the fixed end between a recessed position and an elevated position. The free end has a range of motion limited by contact of the top flange and the bottom flange with the shell. Further, the spoiler is configured to separate the airflow from the outer surface when the spoiler is in the elevated position.

Abstract: The present disclosure is directed to a rotor blade component for a wind turbine. The rotor blade component includes a plurality of pre-cured members arranged in one or more layers. Each of the pre-cured members is constructed of a plurality of fiber materials cured together via a resin material having a first stiffness and at least additional material having a second stiffness. Further, the second stiffness is lower than the first stiffness. As such, the additional low-stiffness material is cured within the resin material so as to increase flexibility of the pre-cured members.

Abstract: A rotor blade for a wind turbine may generally include a first blade component formed from a first fiber-reinforced composite including a first thermoplastic resin material and a second blade component configured to be coupled to the first blade component at a joint interface. The second blade component may be formed from a second fiber-reinforced composite including a second thermoplastic resin material. The second fiber-reinforced composite may include a low fiber region and a high fiber region, with the low fiber region having a fiber-weight fraction that is less than a fiber-weight fraction of the high fiber region. In addition, the first thermoplastic resin material of the first fiber-reinforced composite may be welded to the second thermoplastic resin material contained within the low fiber region of the second thermoplastic composite to form a welded joint at the joint interface between the first blade component and the second blade component.
