Abstract

A high acceleration umbilical cable deployment system for enabling electrical communication between a ballistic projectile forebody and an afterbody. A cable coiled on a spool is housed within a ballistic casing having a drag funnel at the rear end. The cable is sandwiched between a foam plug and the drag funnel before it leaves the forebody and is secured in a strain relief at the apex of a funnel in the afterbody. On deployment, when the bodies are separated, energies that would tend to rupture the cable are expended by the funnels, plug and strain relief.
