Vertical axis wind turbine with integrated centrifugal flaps

Vertical axis wind turbine with integrated centrifugal flaps

This hybrid is using the resistance and buoyancy principle. It is characterized by aerofoils with integrated split flaps, which are opened by repelling magnets at low wind speeds. The result: the rotor starts up much easier and at lower wind speeds. As the rotation speed increases the magnetic opening effect is overcome by the centrifugal forces, which act on the flaps. As a consequence, the flaps fold in automatically. By doing this the wind turbine works at low speeds as a drag-based and at higher speeds as a lift-based wind turbine. Without any complex mechanics and cybernetics, the turbine always works in the optimum operating range. Due to further improvements on the inside of the profile, our wind turbine with centrifugal flaps is able to generate up to 600% more starting torque.
