FIELD: machine building.
SUBSTANCE: invention relates to rotor blade of wind-driven power plant. Rotor blade of wind-driven power plant (1, 1', 1ʺ) comprises root part of blade and end part (5) of blade, flange (7) located on the side of root part of blade for attachment of rotor blade to hub of rotor of wind-driven power plant and bearing (9b, 9a) of axial hinge to adjust rotor blade attack angle (β). Rotor blade has fixed structural frame element (11), on which flange (7) is made, wherein bearing (9b, 9a) of axial hinge is fixed on said structural frame element (11) and is located at a distance from flange (7) towards end part (5) of the blade. Structural frame element (11) between bearing (9a, b) of axial hinge and flange (11) has a section inclined relative to mounting axis (P) so that this mounting axis (P) in the rotor blade mounted on wind-driven power plant is located from axis (T) of the wind-driven power plant (100') is further than flange (7).
EFFECT: invention is aimed at reducing the axle hinge bearing load.
