Abstract

A rotor blade assembly for a wind turbine includes a rotor blade having a pressure side member, a suction side member, a leading edge, and a trailing edge extending between a tip and a root. An electrically conductive band extends longitudinally on either or both of the pressure side member and suction side member along the trailing edge. A plurality of electrically conductive noise reduction features extend from the trailing edge and are configured as individual lightning strike receptors. The noise reduction features are configured in conductive communication with the conductive band.
