基于烤燃试验和数值计算研究了一种新型隔热弹衣材料的热防护性能。通过包覆隔热弹衣无装药试验件烤燃试验获得了新型隔热弹衣材料的热防护效果,基于试验结果通过数值计算获得了新型隔热弹衣材料的热物理参数,基于此开展新型隔热弹衣材料热防护性能分析,数值计算结果表明新型隔热弹衣材料热防护效果显著,可有效延迟装药热点火反应时间,为火灾环境条件下的弹药救援处置赢得时间。

The thermal protection effect of a new thermal protection coat material was researched by fast cook-off and numerical simulation. Based on fast cook-off test, in which the test sample was coated with thermal protection coat but without explosives, the thermal protection effect was investigated. Equivalent thermal physics parameters of thermal protection coat material were obtained by numerical simulation and the numerical simulations were presented to analyze thermal protection performance of new thermal protection coat material. The resuits indicated that the protection effect of new thermal protection coat material was obvious. The ignition reac tion time was effectively delayed. The new thermal protection coat material can obviously gain more time for ammunition succor in fire.
