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.
