WIND-DRIVEN MACHINE WITH COUNTER-FORCING SCREEN Russian patent published in 2011 - IPC F03D1/00 

FIELD: machine building.

SUBSTANCE: wind-driven machine with counter-forcing screen consists of reactive radial ultimate-forcing turbine positioned before counter-forcing screen. The turbine consists of a hub, of twelve spokes on ends of which there are secured twenty four straight-line free bearing yards, of twelve sails stretched on neighbour yards of internal and external contours formed with yards (there are formed reactive surfaces, space between adjacent sails is formed with reactive nozzles of turbine restricted with the counter-forcing screen on one side, while on another side - with a bandage), of bandage of constant width attached to ends of yards, and of the counter-forcing screen. The screen consists of a counter-forcing disk with an orifice in centre, of two cantilevers whereto the disk is rigidly attached and of two brackets whereto the cantilevers are fixed. The turbine is mounted on a shaft resting on bearings rigidly tied with a rotary platform. As an electric generator there is used a low-inertia axial synchronous multi-poles generator of electric current with external excitation kinematically connected with the turbine through a pulley by means of belt transmission. A device for control over external loading on the generator corresponds to a centrifugal regulator kinematically coupled with the turbibe shaft and electrically connected with the generator. The rotary platform is rigidly tied with a vertical support in its base resting on a vertical pivot. At the top the vertical support is located inside a washer resting of a bearing rigidly jointed with the support. Four braces are attached to the washer facilitating fixation of the wind-driven machine in a vertical position. Also, lower ends of the braces are attached to piles.

EFFECT: maximal efficiency of wind-driven machine.
