Investigation of the Interaction of Weapon-Ammunition Subsystems
Pagination or Media Count:
The initial phase in a systematic analysis of weapon-ammunition interaction has been accomplished. Acceptance-test data for five manufacturers production of 5.56mm ammunition were analyzed through time-series modeling, an empirical cumulative distribution function was formulated, and a bivariate histogram of chamber pressure and port pressure was developed for use in the selection of weapon-test ammunition. Statistical experimental design procedures based on factorial or fractional factorial approaches are included for use in tests to identify the controlling parameters in weapon-ammunition interactions and to determine whether these parameters can be identified from ammunition acceptance-test data.
