Abstract:
1. A wind turbine comprising, a vertically driven shaft ( 3 ), having a rotor (F) and a generator ( 7 ) connected with the driven shaft ( 3 ), and a supporting structure including upper and lower bearings for supporting the driven shaft ( 3 ) of the rotor (F), a plurality of supporting rings ( 11 ) perpendicularly attached to the driven shaft ( 3 ) so as to be spaced from one another, a plurality of arcuate beams ( 2 ) fitted with the rings ( 11 ) in a common plane therewith and supporting turbine blades ( 12 ), baffle means ( 1 ) having deflecting and supporting elements as efficiency enhancers ( 13 ) arranged between an inner diameter (d 3 ) and an outer diameter (d 4 ) thereof arranged around the rotor (F), a wind passage (S) formed between edges placed on the inner diameter (d 1 ) of adjacent blades ( 12 ), the turbine blades ( 12 ) are formed as a shape determined by at least one curve selected from a group of curves consisting of quadric, trigonometric and hyperbolic mathematical curves, a plurality of parting vanes (c) are arranged in a plane perpendicular to generatrices of the turbine blades ( 12 ), wherein a number of the efficiency enhancers ( 13 ) is equal to a number of the baffle means ( 1 ), the efficiency enhancers ( 13 ) form a closed polygon, and a support runway (G) mounted to the baffle means ( 1 ) surrounding the rotor (F) and including a ring (t) engaged by a race ring (n) extending from outer diameter (d 2 ) of the rotor (F).
