    摘要: A heater mat assembly for a rotor blade spar is provided including a plurality of electrically conductive heater wires extending in a spaced parallel configuration along a path of the rotor blade spar. An electrical current is flowed through the plurality of heater wires to inhibit ice accumulation on a portion of the rotor blade spar. At least one layer of a first insulating material is arranged adjacent a first side of each of the plurality of heater wires such that the at least one layer of the first insulating material is disposed between the plurality of heater wires and an adjacent surface of the rotor blade spar. The first insulating material comprises a thermally and electrically insulating material.
