为增加铝热剂高温熔穿销毁未爆弹药的安全性,极大可能减小爆轰可能性,减少弹药销毁爆炸率。根据燃烧-爆轰理论、炸药燃烧理论,构建不同弹丸装药类型、装药直径与所需的最小熔孔面积的三维关系模型。并通过三维模型预测某装药密度为1600kg/m³的三硝基甲苯(TNT),装药圆径为80mm、面积A_b为0.005m²的弹药的最小熔孔面积A为0.00015m²。利用金属基可燃胶体对某80mm内径铝合金壳体进行模拟弹药灼烧试验,结果表明200g金属基可燃胶体对某80mm内径铝合金壳体能够可靠灼穿,熔孔面积约为0.0012m²,大于数学模型所推出的理论最小熔孔面积。模型的建立为确定挤胶用量和挤胶面积是否合理提供了一个理论的支撑,从而实现科学、安全销毁未爆弹丸的目的。

In order to increase the safety of high-temperature melt-out of aluminum heat agents through the destruction of unexploded ordnance,significantly reduced the possibility of detonation,and reduced the rate of ammunition explosion,according to the combustion-detonation theory and the explosive combustion theory,a 3D model was used to predict the minimum melt hole area of the ammunition was 0.00015m² with a ammunition which had the 1600kg/m³ density of TNT and the 0.005m² area of a circle.The metal based combustible colloid was used to simulate the burning experiment of a 80mm shell.The experimental results shown that the 200g of metal based combustible colloid can burn through a 80mm shell reliably,and the area of melting hole was larger than the theoretical minimum area of melting hole,which can ignite safely.The modle provided a theoretical support for area and dosage of squeezed rubber to achieve of scientifically and safely destroying unexploded projectiles.
