ROTARY BLADE FOR A WIND POWER PLANT AND WIND POWER PLANT Russian patent published in 2022 - IPC F03D1/06 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to a rotary blade (1) with an underpressure side and a pressure side for a wind power plant, wherein the rotary blade has: - a butt end (2) of the rotary blade in the hub area (I) for attaching the rotary blade (1) to the hub of the rotor, - an end part (3) of the rotary blade, located on the side of the area (II) of the end part facing away from the butt end (2) of the rotary blade, - at least one turbulator (9) located between the butt end (2) of the rotary blade and the end part (3) of the rotary blade, wherein said at least one turbulator (9) in the longitudinal direction of the rotary blade comprises swirling elements (10, 11) located next to each other, with the length (L) and height (H), and each oriented at an angle to the direction (SR) of the main flow of the rotary blade (1), wherein said swirling elements (10, 11) in the longitudinal direction of the rotary blade have a lateral distance (D, D₁) between them. Depending on the corresponding distance (R) between the system of swirling elements (10, 11) and the butt end (2) of the rotary blade, there is a variation in the geometric shape of the swirling elements (10, 11).

EFFECT: creation of a rotary blade for use in a wind power plant.
