ABSTRACT:
A combination wind rotor and output energy transducer to provide output energy from the system and to automatically regulate the wind rotor at all wind velocities to thereby allow the wind rotor to operate at a constant tip speed/wind velocity ratio and at its maximum efficiency. The energy transducer is a combination of positive displacement hydraulic pump and an orifice in the hydraulic system to generate heat. Overspeed protection is afforded by maximum hydraulic loading of the wind rotor in extreme wind conditions.
A wind rotor steering system by which the wind rotor is oriented into the wind at all wind velocities. The wind rotor restoring torque is automatically in balance with its reaction torque.
