The system is designed to cut a 3 ⁄ 8-inch (9.5 mm) steel cable with a breaking strength of 12,000 lb (5,400 kg). [ 7 ] The WSPS developed by Bristol, which is typical of most cable cutters today, consists of a roof-mounted cutter, a lower cutter fitted to the fuselage, [ b ] and a deflector fitted to the middle of the windshield to guide the ...
In stricter senses, the term wire rope refers to a diameter larger than 9.5 mm (3 ⁄ 8 in), with smaller gauges designated cable or cords. [1] Initially wrought iron wires were used, but today steel is the main material used for wire ropes. Historically, wire rope evolved from wrought iron chains, which had a record of mechanical failure.
On aircraft carriers there are either three or four cables, numbered 1–4 from aft to forward. Pendants are made of wire rope with a diameter of 1, 1 + 1 ⁄ 4 or 1 + 3 ⁄ 8 inches (25, 32 or 35 mm).
A safety wire is used to ensure proper security for a fastener. The wire needed is long enough to reach from a fixed location to a hole in the removable fastener, such as a pin — a clevis fastener, sometimes a linchpin or hitch-pin through a clevis yoke for instance — and the wire pulled back upon itself, parallel to its other end, then twisted, a single end inserted through a fastener ...
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of struts, which act in compression or tension as the need arises, and/or wires, which act only in tension.
[2] [3] For shallow water surface supply air diving, the diver's umbilical is typically a 3-part umbilical comprising a 3 ⁄ 8 inch (9.5 mm) bore breathing gas hose, 1 ⁄ 4 inch (6.4 mm) bore pneumofathometer ("pneumo") hose, and diver communications cable, which usually also serves as a lifeline strength member. The pneumo hose is open at ...
