Vertical-axis wind turbine

A wind turbine, comprising:

• a stator having lower and upper support structures interconnected by vertical guide vanes of the stator,
• a rotor comprising a rotor body having a general approximate shape of a hollow truncated cone tapering upward, and rotor blades installed on an outer surface of the rotor body,
• upper and lower support members,
• upper and lower half-axles for rotation of the rotor installed in the upper and lower support members respectively, wherein the upper and lower half-axles define a vertical axis of rotation of the rotor relative to the stator,
• a cross-piece, the upper support member being secured to the upper support structure of the stator with the help of the cross-piece,
• an upper impeller secured inside an upper part of the rotor body, the upper part of the rotor body being secured to the upper half-axle for rotation of the rotor with the help of blades of the upper impeller,
• a lower impeller arranged in a lower part of the rotor body, wherein blades of the lower impeller connect the rotor body with the lower half-axle for rotation of the rotor,
• a confuser with blades, installed on the lower support structure of the stator, the lower support member being secured at a top of the confuser,
• a diffuser installed at least partially above the stator, the diffuser comprising two spaced biconvex discs, the two spaced biconvex discs including a lower disc and an upper disc, respectively, the lower disc being rigidly connected to the upper disc, while serving as the upper support member of the stator, and
• a rotor fan installed in a cavity of the lower disc of the diffuser, wherein blades of the rotor fan are wrapped around the outer surface of the rotor body, wherein a spacing of the blades of the upper impeller is greater than a spacing of the blades of the rotor fan,
• wherein:
• the guide vanes of the stator have a curved surface and are oriented outward, and
• a respective surface of each of the rotor blades has a hyperbolic shape.
