Abstract: The erosion of gun barrel is a main deterrence for improving the gunperformance.In this paper,the erosion principle of gun barrel was analyzed and a newfilm cooling technology was presented.In this technology,the coolant was put into thecombustible case.With this cooling technology,the gun interior ballistic characteristicsand the durability of gun barrel were improved.

Key words: Gun interior trajectory;Gun barrel life;Ablation;Gas cooling
