Abstract
The present disclosure is directed to a rotor blade assembly for a wind turbine. The rotor blade assembly includes a rotor blade having a body shell with a pressure side, a suction side, a leading edge, and a trailing edge each extending between a root portion and a tip portion. Further, the rotor blade assembly includes a protection system configured to protect the rotor blade from ice accumulation or a lightning strike. The protection system includes at least one organic conductive element configured within the rotor blade. The protection system also includes a conductor source electrically or thermally coupled to the organic conductive element. Thus, the conductor source is configured to heat the organic conductive element so as to prevent ice from accumulating on the rotor blade or to provide a conductive path for the lightning strike.
