HEATED ROTOR BLADE OF WIND TURBINE Russian patent published in 2017 - IPC F03D80/00 F03D80/40 F03D1/00 

FIELD: power industry.

SUBSTANCE: invention relates to a blade (1) of a wind turbine rotor (100). The blade (1) of the wind turbine rotor (100) comprises a heating device (33) to heat the blade (1) of the rotor disposed in the blade (1) of the rotor in the surface area of the rotor blade. The heating device (33) has electrically conductive heating wires (2). The heating wires (2) have a sinusoidal, wavy or zig-zag passage shape with an amplitude defining the amplitude of a sinusoidal wave, the wave height or, respectively, the height of peaks and with a wavelength defining the distance between two peaks of the wave or of the distance between two neighbour peaks, respectively. The amplitude and / or the wavelength varies along the heating wires (2) to provide control of specific characteristic of the surface heating of each section of the heating device (33).

EFFECT: increase of the specific characteristic of the heating of the rotor blades and in particular of the rotor blades tip.
