A ramming brake is provided for use with a projectile launched from the barrel of a gun having a tapered portion. The ramming brake includes a braking ring that has a tapered surface configured to wedge into a tapered portion of the gun barrel. In a particular configuration, the braking ring wedges in the tapered breach of the gun barrel. The ramming brake further includes a retaining mechanism that is used to couple the braking ring to the projectile. This retaining mechanism restrains and controls the movement of the projectile after the braking ring wedges into the tapered portion of the barrel.

An obturator is provided for a projectile launched from a gun barrel. The projectile has a mid-body annular groove that includes a shaped surface. The obturator includes an annular ring having an inner surface in contact with the shaped surface of the annular groove of the projectile. The annular ring further includes an outer surface. When the projectile is in the gun barrel, the outer surface of the annular ring contacts an inner surface of a bore of the gun barrel. The radial distance between the inner surface and the outer surface of the annular ring substantially equals or exceeds the radial distance between the shaped surface of the annular groove and the inner surface of the bore of the gun barrel at at least one point when the projectile is positioned in the barrel. This feature restricts a flow of charge gases from an aft end of the projectile to a forward end of the projectile when the projectile is launched from the gun barrel.

Contact insertion and wire lay apparatus for manufacture of wire harnesses which provides for insertion of a contact affixed to the trailing end of a wire segment after wire lay. The invention provides for gripping a wire segment while the segment is caused to lay in a desired configuration. A pair of sets of tip jaws enable forward and trailing end contacts of the wire segment to be inserted into selected contact holding devices. In addition, the apparatus is arranged to facilitate lateral receipt and rejection of the wire segments.

A payguide mounting bracket assembly is connected to a support stand, and a spool is connected to the payguide mounting bracket assembly to have a fiber optic coil formed thereon. A pair of payguide assemblies are demountably coupled to the payguide mounting bracket assembly. A robotic manipulator assembly is configured to decouple a selected one of the first and second payguide assemblies from the payguide mounting bracket assembly and move the selected payguide assembly to a location adjacent the spool such that a layer of optical fiber is paid out to the spool from the selected payguide assembly as the spool and payguide mounting bracket assembly rotate relative to the selected payguide assembly. The invention also preferably comprises further comprises an epoxy applicator assembly configured to be demountably coupled to the robotic manipulator assembly for movement to a location adjacent the coil for applying epoxy to the coil.
