Test and Evaluation of Value Engineering Proposal: Removal of Rubber PAD in 120 MM PA 153 Ammunition Fiber Container

摘要

Rubber pad expanded neoprene is currently positioned in the container body assembly. It is fastened with adhesive to the metal end, which is crimped to the outer body portion of the fiber container. Extensive testing was performed on the cartridge support during design, pre-production, and FAT testing on past and current contracts by U.S. Army Armament Research, Development and Engineering Center personnel. The cartridge support has shown excellent strength at both elevated and negative temperatures. The container itself is designed and manufactured in a way as to add additional strength to the support. The fiber container, by forming an exterior barrier around the cartridge support also helps in controlling the amount of expansion the cartridge support can achieve. By removing the rubber pad, an initial cost savings of $0.32 per container would be achieved.
