초록

The present disclosure 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...
