Abstract
A wind turbine blade includes a first blade segment and a second blade segment, with each of the blade segments having a pressure side shell member, a suction side shell member, and internal support structure. The first and second blade segments have respective adjacent ends with complimentary joint sections that are joinable at a chord-wise joint. Each of the joint sections includes a joint profile that is offset in a span-wise direction from the pressure side shell member to the suction side shell member such that the joint sections are joinable to each other along their respective joint profiles and overlie each other in a span-wise direction.
