WINDMILL Russian patent published in 2001 - IPC

FIELD: wind-power engineering; mechanical and electrical energy generation. SUBSTANCE: windmill has wind turbine with vertical axis of revolution. Novelty is that turbine is assembled of N shaped axisymmetric blades joined together by means of top and bottom circular lids; turbine is placed inside guide system assembled of K fixed axisymmetric guide vanes joined together by means of top and bottom lids; each blade of wind turbine is, essentially, part of cylinder side surface whose generating line is parallel to axis of turbine revolution; cross-sectional area of each guide vane is shaped as sinusoid; inner and outer edges of wind turbine blades are respectively arranged in section over circumferences and are positioned so that smooth air flow is ensured from guide vanes to wind turbine blades; guide vanes are uniformly arranged over circumference with their axes inclined to their radial lines so as to ensure passage of air stream from one blade to other. EFFECT: enhanced utilization of kinetic energy of wind. 6 cl, 1 dwg
