火药

Based on gun bore radial wear Δdmax as discrimination condition of barrel life the mathematical model for predicting melt-erosion of gun-barrel is established which is employed in analyzing factors affecting the life of gun such as material, gun powder,firing conditions and so on. It is pointed out that active cooling technology is an effective method for solving many problems concerned with heat transfer each time the gun is fired.
