WIND TURBINE ROTOR Russian patent published in 2010 - IPC F03D1/06 

FIELD: engines and pumps.

SUBSTANCE: invention refers to wind power engineering, particularly to rotor to be used in wind turbines. Rotor has central bushing, casing and many radial blades adjacent with far ends to the casing in circular section with smaller diametre. Besides rotor is equipped with a connecting ring and many additional radial blades arranged between central bushing and connecting ring, the number of which is smaller than the number of the blades adjacent to the casing. Circular section of the casing with smaller diametre can be the first edge section downstream the wind, owing to which the adapter of casing from the first edge section to the second circular edge section with larger diametre has divergent shape, or the second edge section downstream the wind, owing to which the adapter of casing from the first edge section with larger diametre to the second circular edge section has convergent shape, and blades have the surfaces passing in the direction of the first circular edge section, or it can be intermediate so that two opposite adapters of divergent shape are formed; at that, the first edge section downstream the wind is made with the diametre smaller than that of the second edge section. Adapter of casing can have curved or straight-line profile.

EFFECT: improving energy generation efficiency and decreasing noise and dimensions at available versatile construction.
