| 摘要: |
| 炮管烧蚀一直是火炮性能提高所面临的一个重大障碍，分析了火炮烧蚀的机理，提出了一种将冷却剂直接加于可燃药筒中的新型气膜冷却技术，从而在火炮内弹道性能有所提高的情况下提高了身管的使用寿命。 |

| 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 |
