【摘要】 主要阐述含铝温压炸药配方的基本组成及在不同环境条件下的能量释放效率、爆炸火球及冲击波的形成过程等。通过测试含铝温压炸药在氧气、空气和氩气环境中的燃烧热值,研究不同环境对其爆炸能量释放效率的影响及其使用范围;通过测试爆炸火球和冲击波的成长过程、火球温度和高温火球持续的时间分析含铝温压炸药爆炸机理和破坏效能。结果表明,以超细片状铝粉为主要原料的含铝温压炸药在有氧环境中爆炸的能量释放效率和能量释放速率均较高,其有效破坏效能为较强的爆炸冲击波和持续的高温火球,大大延展温压炸药的综合破坏效能。更多还原

【Abstract】 This paper mainly expatiated the essential components of aluminized thermobaric explosive powder and its energy releasing efficiency in different environments,and dealt with the information of shock wave and fireballs spread abroad within explosion.Heats of the explosive samples were determined in oxygen,air and argon confined in stainless steel container.The effect of the circumstance to the energy releasing efficiency in confined condition was analyzed.Contemporary the energy releasing rates of the different metal additives were qualitatively analyzed.The temperature of the fire balls and the fireballs’ durations were measured in the field test.The relationship of shock wave with fireball expanding was researched.The results indicated that the aluminized thermobaric explosive flake had a higher energy releasing efficiency and energy releasing rates in the oxygen environment.It could have produced a high temperature fireball and strong shock wave which brought an integrative damage.更多还原
