Traveling Charge Computations - Experimental Comparisons and Sensitivity Studies,

Abstract

Theoretical performance studies were conducted for 14 mm gun operated in the conventional and traveling charge (TC) modes using the XKTC interior ballistic code. Conventional charge calculations, done by way of model validation, agreed closely with experimental firings. Traveling charge calculations were done to predict the effects of varying parameters such as TC ignition time and burning behavior on charge performance. For a propelling charge composed of a conventional booster propellant and a TC element, delaying TC ignition past maximum pressure from the booster predicts the greatest improvement in TC performance. TC performance appeared to be less sensitive to the details of burning rate pressure dependence than to overall TC element burn time. Uncontrolled burning characterized by very short burn times leads to excessive gun pressures.
