摘要

摘要: 采用烤燃试验研究了一种隔热弹衣对弹体装药反应的影响。通过对比包覆隔热弹衣试验件和无隔热弹衣试验件火烧后的反应状态，发现隔热弹衣对弹体装药反应等级没有明显影响，但可有效延迟装药热点火反应时间达32min，为火灾环境下弹药救援处置赢得时间。进一步分析发现，隔热弹衣的热防护效果不仅与其自身的低导热性有关，也与隔热弹衣和弹体之间的空气间隙有关。

Abstract: In this work, we researched the influence of a kind of thermal protection coat on the reaction of explosives in projectile by fast cook-off test.Based on the comparison of the reaction state of the test sample with and without the thermal protection coat, the results show that the thermal protection coat had little influence on the test sample's reaction intensity, and delayed the explosives' ignition reaction time by 32 min.The thermal protection coat can obviously win more time for the ammunition succor in fire accidents.Furthermore, the protective effect of the thermal protection coat is related with its own heat-conducting property and the airy space between the coat and the sample protected.
