STRAINED CAPABLE CONDUCTIVE/RESISTIVE COMPOSITE HYBRID HEATER FOR THERMAL ANTI-ICE DEVICE

摘要

A rotor blade of a helicopter is presented. In an embodiment, the rotor blade (100) includes a body (105) ; and a heating mat (301) arranged in the body (105) and configured to supply heat to said body. The heating mat (301) includes a first (505) plurality of fibers (400) and a second (510) plurality of fibers (400) electrically connected to the first plurality of fibers. The first plurality of fibers define a positive angle smaller than about +45° relative to a first direction perpendicular to a longitudinal direction of the body. The second plurality of fibers define a negative angle greater than about -45° relative to the first direction.
