ACOUSTICAL AND VISUAL ATTENUATION THROUGH DYNAMIC REGULATION OF MUZZLE GAS FLOW

Abstract

This paper presents the fundamental concepts of fluid flow on which to base theoretical and empirical studies in the use of weapon muzzle attachments used for flash and sound suppression. It presents the development of an improved flash suppressor for a given weapon and provides a chapter of experimental data to be added to the theoretical data published in the references. When research was initiated on this project, the paucity of published test data left the researcher with something to be desired, that is, the link between theory and reality. The paper further serves to illustrate the fact that here is a fertile field for future research in the field of fluid dynamics. As in most problem solutions, the most coveries continue along the theory of submerged jet flow, heat transfer, thermodynamic properties of propellants, and equations of state of gun gases, the many assumptions now being made during theoretical analysis will be replaced with fact and area of transitional ballistics will become thoroughly defined. This will reduce the art of muzzle device development to a practical engineering science.
