WINDMILL Russian patent published in 2007 - IPC F03D3/00 

FIELD: wind power engineering.

SUBSTANCE: invention relates to windmills with vertical axle of rotation. Proposed windmill contains rotation converter rotated by sail propulsors mounted on vertical shaft and consisting of horizontal masts with sails installed for turning by upper part of masts. Masts are grouped into rows in height of vertical shaft. Number of masts in each row should be not less than three. Height of each sail does not exceed its width. Sail taking-in value is adjusted through guides by traction device operating automatically, depending on velocity of wind. Value of setting of sails arranged on one or several rows of masts is adjusted through additional guides to operate automatically depending on velocity of wind. Traction devices can be made in form of bushings with flyweights rotated with vertical shaft and connected with corresponding guides, thus adjusting value of taking-in and setting of sails depending on speed of rotation of vertical shaft. Proposed windmill is simple in design and it can operate effectively independent of velocity and gusts of wind, region and place of mounting, including movable objects.

EFFECT: improved operation reliability.
