ABSTRACT:
A blade segment of a rotor blade assembly formed from two or more blade segments is disclosed. The blade segment may generally include a body shell and a shear web extending longitudinally within the body shell. The shear web may be disposed between opposed spar caps. The blade segment may also include an attachment member and a spar member. The attachment member may be at least partially disposed within the body shell. The spar member may generally extend outwardly from the spar caps along an inner surface of the body shell and may be configured to support the attachment member within the body shell.
