Abstract
A blade joint for joining a first blade segment and a second blade segment, each having an aerodynamic profile, in a rotor blade is disclosed. The blade joint includes a first joint segment and a second joint segment each having an outer surface, an inner surface, and a thickness therebetween. The outer surface of each joint segment has an aerodynamic profile. The first joint segment and the second joint segment each further have a joint interface end, a blade interface end, and a length therebetween. The joint interface end of the first joint segment and the joint interface end of the second joint segment are configured to couple the first joint segment and second joint segment together.
