A Temperature-Measuring System on the Gun-Barrel Bore of Armor-Artillery Base on 80C196 MCU

Abstract:

when the artillery gun, high temperature propellant gas and cartridge friction would bring serious thermal-influence to the Gun-barrel, they were erosion, abrasion, thermal stress and thermal deformation, and so on. All these would reduce the muzzle velocity，cannon-shot and accuracy, and limit the performance of guns, so its become the restrictions to improve gun power. From some research, all these bad influence relate on the temperature. In order to reduce these bad influence we would know the temperature change during gunning. So it is important to accurately measure the temperature of inner Gun-barrel bore, it is main aim of the paper. In this paper we would utilize the heat-transfer theory to study the temperature distributing in the canal, and apply the film-thermocouple sensor to measure the transient temperature distribute and apply Microcontroller-unit(MCU) technology to deal with these collected data, and then. We would apply compiled software that base on the extrapolation method to calculate the canal temperature. The temperature would offer a reference for take some methods to debase the canal interior temperature. Through some practice measure, the experiment data could arrive at the anticipative aim.
