WIND-POWER PLANT Russian patent published in 1997 - IPC

FIELD: wind-power engineering. SUBSTANCE: plant has hollow mast with guys, two sails, and generator; sails are made in the form of semi- diffusers hinged to hollow mast; multiple-blade windwheel is installed at end of each sail; energy is conveyed from windwheel to generator by means of horizontal shafts through bevel gear to vertical shaft and step-up gear near generator. Sails are made for varying angle of wind incidence (angle between sails) by means of spring that joins sails together so that they fully fold up and windwheel is turned in hinges in parallel to wind flow direction. EFFECT: improved regulation of windwheel speed and provision for automatically taking wind-power plant out of storm wind. 3 cl, 4 dwg
