Internal Ballistics Studies on Compensation of Charge Temperature Effect for Large Caliber Gun System

Abstract

The main aspiration of gun system is to propel projectile at desired range with high consistency and accuracy. Internal Ballistics (IB) plays a very vital role during design and development of gun systems. Initial temperature of charge system significantly affects gun IB performance. It is not always possible to conduct all gun firings at particular temperature conditions. Design of a temperature invariant charge system for large caliber guns is an important area of research in recent times. In this paper, a method is suggested for compensation of charge temperature effect on IB performance using Combustible Cartridge Case (CCC) physical parameters. A multivariate constrained optimization problem is defined for compensation of initial charge temperature effect on IB performance. The simulation results of this method show that the charge system can be converted into temperature independent by altering CCC physical parameters.
