Influence of Ignition Related Parameters and Charge Configuration on XKTC Model Predictions

Abstract

A parametric study has been conducted to assess the influence of ignition related parameters and charge configurations on model predictions using the one-dimensional two-phase flow interior ballistics code XKTC. The investigation showed that the code is sensitive to charge configuration parameters such as bed porosity and ullage, and their effect on compression wave speed. Minimization of ullage and maximization of bed porosity reduce the probability of damaging pressure waves. Substantial changes in interior ballistic performance could be observed for the different kinetics options available in XKTC and for changes in kinetic parameters. Although the code is useful for igniter design, a two dimensional model is recommended for more realistic predictions.
