固体复合推进剂TNT当量计算及其可视化软件开发
|
摘要
利用最小自由能法,编制Matlab程序计算了不同配比固体复合推进剂的C-J爆轰平衡产物,计算固体复合推进剂的TNT当量避免多次实验。分析结果表明:相同质量的固体复合推进剂铝粉质量分数高的爆热值高,对环境的热毁伤大;增加组分中固体炸药的质量分数将提高爆炸性能。
Using the minimum free energy method,the C-J detonation equilibrium products of solid composite propellant with different proportions were calculated by using Matlab program. The calculation of TNT equivalent of composite propellant avoids the consumption of many experiments. According to the calculation and analysis,the high mass fraction of aluminium powder in composite propellant of the same quality can produce high detonation calorific value and cause great damage to the environment. Increasing the mass fraction of solid explosive in components will improve the explosive performance.
