WINDMILL Russian patent published in 2005 - IPC

FIELD: wind power engineering.

SUBSTANCE: invention can be used in wind power plants of different power rating. Proposed windmill contains cylindrical head which is coupled with shaft through sliding and support members. Mounted on shaft of windmill are at least two wind wheels of different diameter with even or odd number of different-length rotary blades, module generator with housing, wind wheel speed synchronizer, device for aiming at wind, conical nut, sealing arrangement, protection hood and turning device. The latter is arranged in front part of cylindrical head and is made in form of bushing which is connected with support plate of stationary tower through sliding and support members. Each wind wheel contains even or odd number of blades of different length combined into working sectors, each provided with at least one blade. Minimum distance between wind wheels with rotary blades should be not less half of diameter of wind wheel with rotary blades arranged behind generator. Wind wheels with rotary blades should be installed on shaft in order of increase of diameters with possibility of axial displacement.

EFFECT: increased capacity of windmill, reduced coast of production.
