wire link
wire link Telemetry in which signals are conveyed by
wire instead of by radio; also called hard-wire telemetry.
wire locking Tying a group of nuts with safety wire to
prevent rotation.
wiresonde Meteorological balloon at low altitude transmitting
data over fine wire(s).
wire-strike kit Measures taken to reduce lethality of
impact between low-flying aircraft, usually small helicopter,
and electric (eg national grid supply) cable.
Simplest form is forward-sloping sharp-edged deflector.
Guillotines [as in WW2] appear to be extinct.
wireway Large conduit forming secondary structure
along which numerous electrical cicuits (occasionally also
fluid lines) are routed; in civil aircraft under floor or
behind trim.
wire-wound Constructed by wrapping ultra-highstrength
(eg tungsten) wire on mandrel and bonding by
plasma spray or other method. Usually final part, eg
rocket case or nozzle, has several layers aligned in
different directions; also called wire-wrapped.
wire-wrapped connection Connection between single
electrical signal wire and terminal made not with solder
but by crimp wrapping by machine designed for purpose.
wiring All internal wires in airship, divided into
structural *, preserving cross-section and other dimensions,
and gasbag *, distributing lift and preventing
chafing.
