The development of an automatic multi calibre weapon system by means of simulation and testing

Abstract

This thesis describes the development of GAMA, (Gun Automatic Multiple Ammunition), a unique, multi calibre, rapid firing weapon with the aid of simulation and testing. Simulation at the time did not fully support the contemporary sophisticated tool sets, and therefore a method was designed to use simulation and experimental development interactively. Simulation models were generated modularly whilst phasing it with the acquirement of experimental test data. Successes in the cross correlation of results progressively supported simulation over the extensive use of testing experimental hardware. Nevertheless, the knowledgeable use of simulation combined with experimental processes supported the practice of calibrating models before use. This prevented time wastage since unnecessary detail did not need to be simulated. Authenticated base line models provided an accredited tool throughout the development of GAMA. Using simulation judiciously and interactively with testing resulted in a foundation for the expansion of GAMA, thus optimising its performance and reliability whilst reducing time and cost. The uniqueness in this project consists of the fact that no similar, multi-calibre gun has existed in the world at the time, nor does it exist today. In addition, many of the simulation techniques used were novel and specifically designed for this project against the background of the world-wide arms embargo against South Africa.
