I am doing a study on split winglets and how they are more advantageous than blended winglets . While browsing through the net, I was reading an article about the Boeing 787 Dreamliner and they had mentioned that these winglets reduce the bending moment . So I was wondering how?

Also can anyone tell me how is it better than blended winglets? Don't they cause more drag though?
