WIND TURBINE BLADE AND METHOD FOR MANUFACTURING SAID BLADE Russian patent published in 2016 - IPC F03D1/00 F03D80/40 

FIELD: engines and pumps.

SUBSTANCE: invention relates to blade for wind turbine rotor and method for manufacturing of such blade. Blade (104a, 104b, 104c, 108, 201) for wind turbine rotor (101) includes housing (218) of blade with bearing surface for arrangement of heating element, electric conductive, in fact, flat heating element (110, 120, 122, 124, 126, 128, 130, 132, 208, 208a, 208b) containing multiaxial carbon fabric arranged on bearing surface and passing in longitudinal direction, in fact, along at least front edge (108) of blade, conductive (112a, 112b, 212, 212a, 212b) power supply, at one end of heating element extending, in fact, across width of heating element on both sides and electrically connected to it, and connecting structure, containing at least one conductive connection element (114a, 114b, 214) and, in fact, covering on both sides of heating element part of electric conductive element, which pass along width of heating element, wherein said blade preferably contains conductive element and connecting structure on both ends of heating element.

EFFECT: invention is aimed at prevention and reduction of icing of blades of wind turbines.
