Heating material for heating aerodynamic surface e.g. tail rotor blade of helicopter, has tape composed of four parallel segments, where two segments are provided at portion of tape that is folded into two zones

摘要

The heating material has a tape (B) composed of four parallel segments (S1-S4). The segments (S1, S2) are provided at a portion of the tape that is folded into two zones (P1, P2). Double folding is made between the segments (S2, S3) and (S3, S4). Ends of the tape permit to connect the tape to an electrical supply unit of an aircraft, to supply the tape continuously and alternately, for operating it in respective anti-icing and de-icing modes.
