摘要
为研究温压炸药的后燃烧性能,制备了TNT/Al炸药。用小型爆炸容器,通过高速摄影仪、压力传感器和温度传感器观测了其后燃烧性能。结果表明,当铝粉的质量分数为20%时,TNT/Al炸药在小型爆炸容器中较易发生后燃烧反应。用高速摄影仪观测到了后燃烧反应和发展过程。由后燃烧反应在爆炸腔形成一定的准静态压力,持续时间达数十毫秒,同时波导管中产生较大压力波动。当铝粉的质量分数为30%时,TAT/Al炸药没有发生后燃烧现象。
To study the after-burning performance of thermo-baric explosive, the TNT/AI explosive was made. The after burning performance of this explosive was observed using a small explosion vessel through high-speed camera, pressure sensor and thermocouple sensor. The results show that the after-burning reactions of the explosive which contains 20% aluminum powder occur more easily in the small explosion vessel. The initiation and the development of after-burning process are observed by high-speed camera. The quasi-static pressure with duration of milliseconds appears in the explosion cavity because of after-burning reaction. Synchronously, the larger pressure wave propaga- tion is formed in the explosion tube. But the afte^burning reaction of the explosive which contains 30% aluminum does not occur.
