ABSTRACT:
A blade segment is disclosed for a rotor blade formed from a plurality of blade segments, the blade segment having a span and a chord. The blade segment includes a shell segment having a pressure side and a suction side extending between a leading edge and a trailing edge, the shell segment further having a tip end and a root end. The blade segment further includes at least one joint portion projecting from the shell segment at one of the tip end or the root end and defining a generally span-wise extending joining surface. The joint portion allows the blade segment to be coupled to an adjacent blade segment with a mating joint portion.
