WIND WHEEL Russian patent published in 2023 - IPC F03D1/06 F03D3/06 

FIELD: wind energy.

SUBSTANCE: wind wheels of wind driven and wind power plants with a horizontal axis of rotation, mainly intended for operation with segment-type electric generators. The wind wheel consists of a shaft and a hub made in the form of a plate, on the periphery of which the inner edges of the blades are fixed. The blades are made in the form of pairs of U-shaped rods containing the first and second racks. The first posts of the first U-shaped rods are mounted on a spacer and are attracted to the plate by a detachable connection, and the second U-shaped rods are attracted by their first posts to the first posts of the first rod also by means of a detachable connection. On each of the rods, with the help of brackets, flexible panels are fixed, forming the plane of the blade, and the inner ends of the panels are provided with tension springs.

EFFECT: increasing the manufacturability and reduction of the weight of the blades, as well as ensuring wind resistance by simplifying the replacement of panels.
