Abstract:

采用灌注成型工艺,将含敏化剂的含能灌注液填充于废弃的双芳-3发射药颗粒的空隙中,制备出灌注炸药。通过见证板试验、高速摄影、空中爆炸及水下爆炸试验分别研究了其爆轰性能、冲击波超压及能量输出特性。结果表明,采用灌注工艺,可制备性能优良的灌注炸药;随着敏化剂含量的增加,炸药的爆轰感度显著提高,但其爆速、冲击波超压及水下爆炸能量输出变化较小;该炸药的密度可达1.52g·cm-3,爆速6600m·s-1(Φ60mm),比例距离为1.65~4.50m·kg-1/3时TNT当量系数略大于1,比冲击波能及总能量分别为1.7,4.16MJ·kg-1,高于常用的工业炸药,略低于TNT。
