Analysis of Heat Migration into a Chambered Round

Abstract

The temperature distribution within the charge of a tank round after its insertion into the gun breech is analyzed using an implicit finite-difference model. The propellant average temperature of the last of a series of rounds is determined as a function of the in-chamber time for a firing rate of six rounds/minute. The effects of propellant temperature, ambient temperature, previous number of rounds fired, and external convection heat transfer coefficient are presented.
