WINDMILL-ELECTRIC GENERATING PLANT WITH DIFFUSER (ALTERNATIVES), METHOD FOR PROTECTING IT AGAINST DESTRUCTIVE ATMOSPHERIC ACTIONS, AND METHOD FOR SETTING UP WINDMILL-ELECTRIC GENERATING PLANT USING ENERGY OF COMPRESSED AIR Russian patent published in 2001 - IPC

FIELD: wind-power engineering; heavy-power windmills. SUBSTANCE: plant with diffuser has windwheel mounted along horizontal axis of revolution that carries hollow blades, air intakes controlled by electric generator, and air turbine. Novelty is that diffuser is flexible structure and that inner spaces of blades are made in the form of helical ducts; diffuser is mounted on floats coupled with supports; novelty in method for protecting plant against destructive atmospheric actions by reducing area or contact between plant and wind flow it that windmill-electric generating plant is immersed in liquid medium, ; novelty in plant setting up using energy of compressed air is provision for flexible diffuser wherein air is injected under higher- than-atmospheric pressure by forced rotation of windwheel in reverse-to- working direction. EFFECT: enhanced reliability of plant protection against atmospheric actions, simplified design, increased power output. 8 cl, 15 dwg
