WINDMILL-ELECTRIC GENERATING PLANT Russian patent published in 2005 - IPC

FIELD: wind-power engineering; off-line windmill-electric generating plants or those operating in parallel with power mains.

SUBSTANCE: proposed plant has induction-type generator, transmission, and windmill, all mounted on endless flexible members thrown over cylinders and having axes of revolution coupled with base. Blade is made in the form of gable roof incorporating couple rafters in the form of dead-end towers. Axis-to-axis distances of cylinders equal 2.5 to 5.5 of their clearance radii. Clearance diameter of cylinders is greater than dead-end tower pitch and is comparable with its height. Flexible members are tensioned with aid of movable supports whose pedestal is disposed between supports and base; pedestals proper are rigidly fixed to beam. Optimal blade number of windmill-electric generating plant is four.

EFFECT: simplified design, reduced cost, enhanced reliability of plant.
