ORTHOGONAL WIND ROTOR Russian patent published in 2010 - IPC F03D3/06 

FIELD: engines and pumps.

SUBSTANCE: orthogonal wind rotor refers to wind power engineering and can be used for conversion of wind energy to other types of energy. Orthogonal wind rotor includes vertical axis and not less than two horizontal beams installed perpendicular to the axis and attached to it with braces. One and more vertical metal frames forming a vertical screen are attached to each beam from above and from below; at that, one and more curtains made form flexible material are hinged to each frame. Each curtain is installed on vertical spokes tightened with bolts in upper part between two metal strips; at that, hinges are formed with bushings installed in frames and arms fixed on metal strips. Curtains are installed one above the other with overlapping in the area of metal strips. On working surface of each curtain between adjacent spokes and parallel to them there installed is one and more armours made from light material and having triangular cross direction profile; at that, each armour contacts the working surface of the curtain by means of one of its edges. Length of each armour corresponds to length of curtain, and height of armour is equal or smaller than thickness of metal strip. Armours are rigidly attached to working surfaces of curtains or each armour is covered with a patch pocket made from flexible material rigidly attached to the working surface of the curtain.

EFFECT: increasing efficiency of wind energy conversion with orthogonal wind rotor to mechanical energy of rotation of its axis.
