DOUBLE-ROTOR WIND GENERATOR Russian patent published in 2011 - IPC F03D1/02 F03D7/04 

FIELD: power engineering.

SUBSTANCE: double-rotor wind generator comprises a stator and two rotors. Inside the stator there is the main rotor and an additionally introduced adjusting rotor, which may rotate relative to each other. The adjusting and the main rotors via conical gears are connected to the axes of the wind wheel blades. Adjustment of the angle of attack is carried out by rotation of the adjusting rotor relative to the main one by shunting of the adjusting rotor winding. At the same time the adjusting rotor rotates relative to the main rotor and turns the gear joined to the wind wheel blade, thus changing the angle of the blade attack.

EFFECT: invention makes it possible to adjust inclination of the blades to the flow in process of their rotation and also increase the accuracy of wind wheel rotation frequency.
