Abstract
A rotor blade for a wind turbine is disclosed. The rotor blade includes a root, a tip, and a body extending from the root, the body including a pressure side and a suction side extending between a leading edge and a trailing edge. The rotor blade further includes a winglet extending between the body and the tip, the winglet including a pressure side and a suction side extending between a leading edge and a trailing edge. The winglet further includes a transition section and defines a height, a sweep angle, an outboard cant angle, and a twist angle. The sweep angle, the outboard cant angle, and the twist angle change continuously throughout the transition section.
