Prediction of Erosion from Heat Transfer Measurements
Abstract
A review is made of existing empirical models for predicting erosion rates of large caliber guns. All the empirical models are based on a correlation between calculated bore surface temperature and the measured wear rate. This prompted an investigation into correlating measured total heat input with the erosion rate. A correlation was obtained even for rounds with different wear- reducing additives. Such rounds have nearly identical interior ballistics but differ in the amount of heat transferred to the barrel and the erosion rate.
