WIND MOTOR Russian patent published in 2010 - IPC F03D3/06 

FIELD: power industry.

SUBSTANCE: wind motor includes vertical shaft fixed on bearings and pair blades installed on horizontal axes connected to vertical shaft with possibility of restricted combined turn. Pair blades are fixed on horizontal axis with hinges. In kinematic link of blades and horizontal axis there installed are elastic elements and restrictors of combined turn of blades at the interaction with which and with restrictors of combined turn of blades the angle between blades is not more than 65° with its decrease at excess design force of wind, angle between horizontal plane and blade moving into the wind is not less than 10°, blade moving in wind direction and vertical plane is not less than 15°, angle of combined blade turn angle - 95-150°. Number of pair blades is not limited and they are turned relative to each other through one angle.

EFFECT: reducing noise and vibration at operation of wind motor by excluding flaps, bumps at working travel and re-laying of blades, protection of the wind engine construction against overloads at increased wind velocity.
