| Summary: | 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. === Thesis (Ph.D. (Mechanical Engineering))--North-West University, Potchefstroom Campus, 2006.
