WIND MOTOR ON BASIS OF AERODYNAMIC SHIELD Russian patent published in 2011 - IPC F03D3/04 

FIELD: engines and pumps.

SUBSTANCE: wind motor on the basis of aerodynamic shield includes air intake 1 with lower air intake, which is equipped with guide ring 2, axial multi-blade fan 6 installed on vertical shaft of electric generator 5. In addition, air intake 1 includes guide grid made of plates located perpendicular to each other. Its guide ring 2 is made in the form of cone-shaped lifting wing and located along the grid edge. Electric generator 5 is installed on base 7 equipped with shock absorbers 8 fixed on foundation and central support axis 9 arranged in spherical bearing 10 fixed in housing 11 installed on foundation.

EFFECT: higher use coefficient of wind energy owing to creating similar conditions of aerodynamic effect on all fan blades and simpler design.
