Classification: CPC F  Y | IPC F

Claim 12:
13. A wind turbine, comprising:
a tower;
a nacelle disposed on the tower;
a generator disposed in the nacelle;
a rotor coupled to the generator and having a distal end extending from the nacelle;
a plurality of blades disposed on the distal end of the rotor; wherein at least blade of the plurality of blades comprises:
a blade shell that defines a suction side, pressure side, leading edge, and a trailing edge of the blade;
a blade heating system comprising one or more heating elements configured to heat the blade in first and second heating areas, wherein the first heating area is closer to the leading edge than the second heating area is, and the heating system is configured to generate heat fluxes in the first and second heating areas such that the heat flux generated in the first heating area is lower than the heat flux generated in the second heating area, wherein the heat flux generated in the second heating area is sufficient to cause water to evaporate on an exterior surface of the blade.
