Abstract: The present subject matter is directed to methods for manufacturing rotor blades and/or components thereof of a wind turbine. In one embodiment, the method includes forming the rotor blade component and covering at least a portion of the rotor blade component with at least one coating material. In addition, the coating material includes at least one additive having a changeable pigment. After the component is formed, the method includes inspecting the rotor blade component for defects. After inspection, the method further includes activating the additive to change the pigment from a transparent finish to a colored finish.

Abstract: The present disclosure is directed to a rotor blade assembly for a wind turbine having a joint assembly securing first and second blade segments together. For example, the joint assembly releasably couples the first and second blade segments together at a chord-wise extending joint and includes at least one set of interlocking components. As such, the joint assembly is movable between a locked position and an unlocked position by engaging and disengaging the interlocking components. Thus, in the locked position, the first and second blade segments are secured together via the interlocking components, and movement from the locked position to the unlocked position, releases the interlocking components, thereby releasing the first and second blade segments from each other.
