WIND TURBINE ROTOR BLADE Russian patent published in 2020 - IPC F03D1/06 F03D80/40 

FIELD: machine building.

SUBSTANCE: invention relates to rotor blade of wind-driven power plant, as well as to wind-driven power plant with appropriate rotor blade. Wind power unit rotor blade (200) comprises rotor blade base area (200a), rotor blade top area (200b), face side (200c), rear side (200d), leading edge (201), trailing edge (202), at least one rib (210, 211, 212) passing between face side (200c) and rear side (200d) and along longitudinal direction (L) of rotor blade (200), deflecting element (250) made between one end of at least one rib (210, 211, 212) and rotor blade apex area to deflect heated air flowing from rotor blade root area (200a) along at least one rib (210, 211, 212), and at least one air intake (270) on one of at least one rib (212). Additionally, it comprises element (280) for boundary layer suction connected to the ends of the first and second ribs (211, 212) located on the rotor blade top side for suction of the turbulent boundary layer or open air flow points.

EFFECT: technical result is providing improved heating of rotor blade.
