JOINT ASSEMBLY FOR ROTOR BLADE SEGMENTS OF A WIND TURBINE

摘要

The present subject matter is directed to a rotor blade assembly and/or a joint assembly for a wind turbine blade. In one embodiment, the rotor blade assembly includes at least first and second blade segments connected together at a chord-wise extending joint, one or more shear-loaded pins configured through the chord-wise extending joint, and an anti-rotation locking feature. As such, the rotor blade assembly includes a maintenance-free bolted joint. The first blade segment has a body shell defining a generally aerodynamic profile. The body shell includes a suction side surface and a pressure side surface. The shear-loaded pin may extend in a generally flap-wise direction (i.e. from the suction side surface to the pressure side surface of the body shell) or in a generally chord-wise direction (i.e. from the pressure side to the suction side of the body shell).

主权项

1. A rotor blade assembly for a wind turbine, the rotor blade assembly comprising:
a first blade segment comprising:
a body shell defining a generally aerodynamic profile, the body shell comprising a suction side surface and a pressure side surface; a second blade segment connected to the first blade segment at a maintenance-free chord-wise extending joint; at least one shear-loaded pin configured through the chord-wise extending joint, the shear-loaded pin extending in a generally flap-wise direction; and, an anti-rotation locking feature configured with the at least one shear-loaded pin, the locking feature configured to secure the shear-loaded pin within the body shell.
