Abstract:

Identification of the burn-through problem associated with high-performance aluminum cartridge-cases was made as the result of studies to isolate the elements of this problem and relate these elements to the interior ballistic cycle of the M16Al rifle system. One practical solution the flexible internal element to this problem was found and when this solution was coupled with improvements in mechanical performance of the aluminum case by new analytical design techniques, tougher high-strength aluminum alloy, and novel case processing techniques, the feasibility of the aluminum cartridge case was demonstrated by a suitable test firing.
