WIND PLANT Russian patent published in 2006 - IPC F03D3/04 

FIELD: wind power engineering.

SUBSTANCE: invention relates to wind plants with guide devices converting energy of air flow and it can be used for generating both mechanical and electric energy. Proposed wind plant contains fixed carrying housing being main guide device made in form of spatial blade cascade with central outlet channel in which working wheel is fitted on vertical shaft coaxially with central axis. Common unit consisting of air intake, nozzle and stabilizer is installed on upper member of housing for free rotation relative to central axis. Spatial blade cascade is formed by two surfaces of rotation and spatial blades in between in form of circular massive, thus forming working channels. Air intake completely encloses working channels of rear zone of guide device, being connected with outlet nozzle for free rotation relative to central axis.

EFFECT: enlarged range of working velocities of on-coming air flow, maximum utilization of its energy, reduction of losses in working duct and increased efficiency of wind plant.
