ABSTRACT:
A multi-segment wind turbine blade comprises at least two blade segments. A first spar cap segment is attached to a first blade segment and a second spar cap segment is attached to a second blade segment. The first and second spar cap segments are configured to form a scarf joint. First and second spar cap brackets are attached in locations of the first and second spar cap segments, respectively, selected to facilitate alignment of the first and second spar cap segments at the scarf joint. At a field site, the first and second spar cap segments are bonded after fastening the first and second spar cap brackets.
