WIND MOTOR Russian patent published in 2010 - IPC F03D3/04 

FIELD: power industry.

SUBSTANCE: wind motor contains wind turbine with vertical rotation axis formed with shaped axisymmetrical blades and guide system in the form of fixed axisymmetrical guide flaps equally located and fixed with upper and lower covers. Blades are formed with outer, middle and inner sides with the ratio of sides as to width of 1:5:10÷1:5:20 respectively. Middle and outer sides of each blade are bent in direction of vertical rotation axis of turbine at angle of 130°÷150° and 90°÷135° respectively. Even blades are arranged with a gap relative to vertical rotation axis, which is equal to 0.067÷0.1 of D₃, where D₃ - wind turbine diametre, and uneven blades are installed against vertical rotation axis. Flaps of guide system are fixed in vertical direction and made in the form of outer and inner sides with ratio as to width of 0.25÷0.5 and angles between sides of 130÷150°; at that, inner side of each flap is installed at an angle of 30°÷60° to the radius of guide system, and outer side - along the radius of guide system. Upper and lower covers of guide system are made in the form of a circle equipped in its peripheral part with a hollow flattened cone with an angle of 130÷150°, diametre of smaller base D₁=1.05÷1.1 D₃ and height H₁=0.25÷0.5D₁.

EFFECT: improving operation of wind motor and increasing efficiency.
