WIND TURBINE SYSTEM BASED ON AERODYNAMIC DRAG WITH ADJUSTABLE BLADES Russian patent published in 2023 - IPC F03D3/06 F03D7/06 

FIELD: wind energy.

SUBSTANCE: variable-blade drag wind turbine system comprises one or more output drive rotors located on a base structure. Each output rotor is connected to one or more arms using one or more primary control devices. One or more blade panel assemblies are rotatably mounted using one or more corresponding levers. Each of the blade panel assemblies includes an auxiliary rotary shaft rotatably mounted on each of one or more arms. The mounting device is connected to an auxiliary rotary shaft controlled by one or more primary control devices. Each blade panel mounting device accommodates one or more sub-blade panels that are rotated at one or more pivot points of the mounting device using one or more secondary control devices to allow one or more sub-blades to rotate, thereby blocking and/or allowing wind to pass through the blades. panels partially or completely. One or more sensors for reading system control parameters are connected to one or more main control units (MCUs) and to one or more processing modules, one or more primary control devices and one or more secondary control devices. The output device is configured to convert the torque of one or more output drive rotors into one or more forms of energy.

EFFECT: improved efficiency of using a wind turbine, expanded range of operating wind speeds, and simplified maintenance.
