The abstract released by U.S. Patent and Trademark Office states, "A modular wind turbine blade is described. The modular blade comprises a first blade 5 module having a first spar cap extending longitudinally in a spanwise direction and a second blade module having a second spar cap extending longitudinally in the spanwise direction. The blade modules are configured for connection end-to-end via their respective spar caps. The first spar cap comprises first and second beams arranged side-by-side, each beam having a tapered end defining a scarfed surface. The tapered end of the first 10 beam extends beyond the tapered end of the second beam. The second spar cap comprises first and second beams arranged side-by-side, each beam having a tapered end defining a scarfed surface. The tapered end of the second beam extends beyond the tapered end of the first beam. The blade modules are configured such that when the modules are connected together the scarfed surfaces of the respective first beams mate 15 to form a first scarf joint and the scarfed surfaces of the respective second beams mate to form a second scarf joint. The first scarf joint is offset from the second scarf joint in the spanwise direction."
