WIND MOTOR Russian patent published in 2017 - IPC F03D1/02 F03D7/02 

FIELD: power engineering.

SUBSTANCE: invention relates to wind power engineering. Wind motor includes a horizontal shaft, fixed on it two identical in design and sizes multiblade wind wheels: a fixed one and a movable one, blades of the movable wind wheel are initially installed in the middle of the fixed wind wheel blades increasing the number of blades of the first level twice, hubs of both wind wheels have mutual half-couplings of clutch cam type ensuring rotation of the movable wind wheel at high wind speeds by a rated angle for screening the fixed wind wheel blades, additionally it contains tension springs and pneumatic shock absorbers to reduce vibration of the movable wind wheel at the transition into the zone of screening the fixed wind wheel blades and to reduce wind load onto the wind motor.

EFFECT: invention is aimed at increasing efficiency of the windmill due to better use of wind force in the central, middle and peripheral zones of wind wheels.
