Directional orientation system for wind driven generator - has torque applied proportional to orientation speed to oppose movement direction

摘要

Directional orientation of wind driven generators or anemometers depends on their mechanical characteristics and on wind speed and pressure variation. Errors are reduced by a moving element which applies torque proportional to speed of movement to oppose direction of movement. A wind driven generator comprises a support which rotates about a vertical axis. A rudder orientates the generator such that the propeller blades are placed in the air current. The rudder supports a tail piece which is able to rotate about a vertical axis, against the return action of a spring. A rotating damper on the generator pivot drives the tail piece via a cable and pulleys to provide a torque proportional to speed of generator orientation.
