WIND TURBINE ROTOR BLADE

摘要

A wind turbine rotor blade comprising: a flap for modifying the aerodynamic surface of the rotor blade; a chamber disposed in the rotor blade and configured such that movement of the flap causes a property change in the chamber, the property change being a change of air pressure within the chamber and/or a change of the volume of air in the chamber; a nozzle disposed on the aerodynamic surface of the rotor blade and in fluid communication with the chamber; wherein the chamber and the first nozzle are configured such that the property change in the chamber generates an air mass flow through the nozzle.
