Abstract

A wind turbine blade includes a root portion, a tip and a body extending between the root portion and the tip. The body has a pressure side and a suction side. The body further has at least one winglet. Each winglet has a spanwise extension towards the root portion of the rotor blade and that ends at the tip to form a winglet having a substantially C-shaped or substantially open P-shaped geometry.
