Fiber cable made of high-strength synthetic fibers for a helicopter recue winch
View Patent ↗A fiber cable for helicopter rescue winches includes a plurality of load-bearing synthetic-fiber strands braided with one another, at least one electrically conductive insert, and a wear indicator providing a visual check of a state of the fiber cable, where the load-bearing synthetic-fiber strands are encased in a radial direction by a friction-reducing stable fiber layer, an inner cable jacket, and outer cable jacket.
1. A fiber cable for a helicopter rescue winch, the fiber cable comprising:
an electrically conductive wire;
a plastic sheath encasing said wire;
a plurality of load-bearing synthetic-fiber strands braided with one another and encasing said plastic sheath,
wherein forces acting on the cable are carried exclusively by said plurality of load-bearing synthetic-fiber strands; and
a coating encasing said plurality of load-bearing synthetic-fiber strands.
2. The fiber cable of claim 1 , wherein said wire forms an innermost core of said fiber cable.
3. The fiber cable of claim 1 , wherein said wire is one of a plurality of wires that are braided into said plurality of load-bearing synthetic-fiber strands.
4. A fiber cable for a helicopter rescue winch, the fiber cable comprising:
an electrically conductive, single wire core;
a plastic sheath encasing said wire core;
a plurality of load-bearing synthetic-fiber strands braided with one another and encasing said plastic sheath,
wherein forces acting on the cable are carried exclusively by said plurality of load-bearing synthetic-fiber strands; and
a coating encasing said plurality of load-bearing synthetic-fiber strands.
5. The fiber cable of claim 4 , wherein said coating is polyurethane.
6. A fiber cable for a helicopter rescue winch, the fiber cable comprising:
a plurality of load-bearing synthetic-fiber strands braided with one another, wherein forces acting on the cable are carried exclusively by said plurality of load-bearing synthetic-fiber strands; and plural electrically conductive, wires braided into said plurality of load-bearing synthetic-fiber strands; a plastic sheath encasing each of said wires; and a coating encasing said plurality of load-bearing synthetic-fiber strands.
