Abstract: The present disclosure is directed to a method for manufacturing a blade component for a rotor blade of a wind turbine. The method includes arranging a fiber material in a mold of the blade component. The method also includes placing at least one pre-cured laminate material atop the fiber material. Another step includes infusing the fiber material and the pre-cured laminate material together via a resin material so as to form the blade component. The method also includes allowing the blade component to cure, the pre-cured laminate material forming at least a portion of an outer surface of the blade component.

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: Methods of manufacturing rotor blades for a wind turbine and rotor blades produced in accordance with such methods are disclosed. In one embodiment, the method includes forming a first spar cap of the rotor blade from a first resin material. Another step includes placing the first spar cap within a first shell mold of the rotor blade. A further step includes infusing a second resin material into the first shell mold to form a first shell member of the rotor blade. Thus, at least a portion of the first spar cap is infused within the first shell member. Further, the second resin material is different than the first resin material. The method also includes infusing the second resin material into a second shell mold to form a second shell member of the rotor blade. Another step includes bonding the first and second shell members together so as to form the rotor blade.

Abstract: A method for producing a hollow composite structure, such as a spar beam for use in a wind turbine blade, includes placing fiber reinforcement material around a mandrel within a mold, and curing the fiber reinforcement material. The mandrel is formed from a compressible material having a rigid neutral state with a rigidity to maintain a defined shape of the mandrel during lay up and curing of the fiber reinforcement material. Subsequent to curing, a vacuum is drawn on the mandrel to compress the compressible material so that the compressed mandrel can be drawn out through an opening in the composite structure, the opening having a size such that the mandrel could not be withdrawn through the opening in the rigid neutral state of the mandrel.

Abstract: A jointed rotor blade includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. Each of blade segments has at least one shell member defining an airfoil surface and an internal support structure. The internal support structure of the first blade segment includes a beam structure extending lengthwise that structurally connects with the internal support structure of the second blade segment via a receiving section. The rotor blade further includes one or more pin joints positioned on at least one of internal support structures of the first blade segment or the second blade segment. Thus, at least one of internal support structures of the first blade segment or the second blade segment includes varying material combinations along a span of the rotor blade at locations of the one or more pin joints so as to reinforce the one or more pin joints.
