WIND TURBINE WITH ROTOR BLADES EQUIPPED WITH WINGLETS AND BLADES FOR SUCH ROTOR

摘要

A wind turbine is disclosed comprising a rotor with wind turbine blades each having a root end connected to a hub of the wind turbine and a tip end, the tip end of each of which being equipped with a winglet extending a distance in a direction perpendicularly to a longitudinal direction of the blade. A new and much more slim design of the outer part of the wind turbine blade is disclosed, i.e. with a shorter chord length designed within a narrow band of values defined with respect to the length of the winglet, i.e. the extension in the direction transverse to the longitudinal direction of the blade.
