Vertical axis wind and hydraulic turbine with flow control

A vertical axis wind and hydraulic turbine with flow control comprising:

• a regular hexagonal structure (7), the regular hexagonal structure having a first radius (R), and a parallelepiped shape;
• a rotor (6) located inside the regular hexagonal structure (7), the rotor having a wind or liquid inlet, a wind or liquid outlet, and three or more rotor vanes that, in top view, rotate on a vertical rotor axis which is located in a center of the regular hexagon structure,
• wherein said three or more rotor vanes rotate to generate a circle of a second radius (Rt) and a flow of air or liquid enters the rotor vanes through the wind or liquid inlet on a wind or liquid current entry side and then exits from the rotor vanes on a side opposite to the wind or liquid entry side;
• and
• exactly six articulated deflector vanes, wherein the six articulated deflector vanes i) grab and concentrate the flow of air or liquid entering the rotor vanes, from the wind or liquid current entry side and ii) diffuse the flow of air or liquid exiting from the rotor vanes, on the side opposite to the wind or liquid entry side, wherein,
• each one of the six articulated deflector vanes comprises a fixed part (3) and a movable part (2) movable between a closed position and an open position,
• each of said fixed parts (3) has a first inner end located adjacent the circle of a second radius (Rt) generated by the rotation of the three or more rotor vanes of the rotor (6), the first inner end of each of said fixed parts (3) having a curved surface that extends along a circle of a third radius (Rt′), the circle of a third radius (Rt′) being located adjacent the circle of a second radius (Rt),
• each said fixed part (3) has a second outer end located adjacent a vertex of the regular hexagonal structure (7) located on the circle of a first radius (R) of the regular hexagonal structure (7), the second outer end of each said fixed part (3) having a curved end surface with a fourth radius (r′),
• each of said movable parts (2) has a first inner end pivotally mounted on a pivot axis located at one of the vertices of the regular hexagonal structure (7) and parallel to the rotor axis, the first inner end of each said movable part (2) having a leading edge (10) defined by a convex semicircle having a radius of curvature (r) corresponding to the fourth radius (r′) of the curved end surface of the second outer end of each said fixed part (3),
• in the open position of each said movable part (2), the leading edge (10) of each said movable part (2) extends along and adjacent the curved end surface of the second outer end of a corresponding one of said fixed parts (2), and
• each of said movable parts (2) has a second outer end that defines a trailing edge (9) of each articulated deflector vane and a mean curvature line (LCM) that extends from the first inner end, through the pivot axis, to the trailing edge (9).
