SAIL-TYPE WIND TURBINE Russian patent published in 2024 - IPC F03D5/02 F03D7/00 

FIELD: wind power engineering.

SUBSTANCE: wind turbine comprises chain circuits with horizontal shafts and blades installed at an angle to horizon and installed by means of guide chutes perpendicular to wind flow from windward side and parallel to it from leeward side. All this is mounted on common frame, one end of which is pivotally fixed on horizontal rotary platform in bearings of lower shaft of chain circuits, and the other end is spring-loaded with the help of springs between upper shaft of chain circuits and levers of rotary platform. Springs inside have rods pivotally mounted on the upper shaft, the lower ends of which freely pass into the lugs of the levers of the rotary platform.

EFFECT: providing stable rotation frequency of chain circuit at sharp changes of wind load.
