Abstract:

Computers have already been used to fingerprint ammunition. Geene states that his model provides an aid in defining more meaningful acceptance criteria for small arms propellants. Geenes study was aimed at illuminating the reasons for ammunition causing weapon performance failures after passing acceptance tests. Geenes Energy Equation model does provide some insights into propellant burn and projectile dynamics, however his model does not match the data very well. Instead of beginning our work by using Geenes model as a springboard, our approach has been to develop a set of non-linear differential equations which describe the dynamics of the physical system. The simulation of these differential equations was performed on an EASE 2133 analog computer and a PDP-7 digital computer connected through 24 channels of analogdigital and digitalanalog converters.
