ABSTRACT

In this paper the basic points of mathematical model for determining range of artillery projectiles with base bleed are presented. After verification of the model by comparison with experimental data, a parametric study of the effect of some characteristics of base bleed on range was carried out. In was found that the range of a given projectile depends on the number of grain segments, burning rate, internal diameter and grain length. The model can be used for selecting characteristics of grain that will give the maximum range of projectile and for decreasing the number of experimental firings for determining those characteristics.
