摘要： 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.

摘要： A counterweight system for mounting a rotor blade on a balanced rotatable hub of a wind turbine is disclosed. The rotatable hub can have at least one blade root region configured to receive a blade root of the rotor blade, and also have a pitch system configured to rotate the rotor blade around a pitch axis. The counterweight system can have at least one support structure having a proximal end spaced apart from a distal end with the proximal end mountable to at least one blade root region of the rotatable hub. The at least one counterweight mass can be at least partially filled with fluid and coupled to the distal end of the at least one support structure. The at least one support structure can be arranged substantially parallel to the pitch axis such that the pitch system rotates the counterweight mass about the pitch axis.

摘要： A system for locating airflow modifiers for installation on wind turbine rotor blades may generally include a plurality of airflow modifiers, with each airflow modifier including a base defining an outer profile that differs from the outer profiles of the remainder of the airflow modifiers. The system may also include a blade shell defining an exterior surface. The base of each airflow modifier may be configured to be coupled to the exterior surface of the blade shell. In addition, the system may include an installation template provided on the exterior surface of the blade shell. The installation template may define a different installation location for each of the airflow modifiers. Moreover, the installation template may include a geometric feature at each installation location that at least partially matches the outer profile of the airflow modifier configured to be installed at such installation location.

摘要： In one aspect, a method for manufacturing a rotor blade for a wind turbine is disclosed. The method may generally include assembling a blade blank comprising a shear member and a volume of core material and removing material from the blade blank to form a body having a pressure side and a suction side extending between a leading edge and a trailing edge. The shear member may have a first end disposed adjacent to the pressure side and a second end disposed adjacent to the suction side. In addition, the method may include positioning a skin around an outer perimeter of the body.
