摘要
为对比研究2种不同组份及装药工艺的复合温压炸药装药的爆炸特性,本文在空气环境下开展了相关静爆试验,测试了2种温压炸药装药起爆后的冲击波超压、火球直径和火球表面温度参数,并与相同质量的TNT进行了对比。研究结果表明:在相同装药质量下(装药质量为2 kg),H-1(奥克托金HMX/铝Al/粘结剂)装药的冲击波超压要高于R-1(黑索金RDX/高氯酸铵AP/铝Al/粘结剂),但R-1炸药装药起爆后形成的火球表面温度更高,且高温持续时间较H-1更长;同时,按照超压值计算,H-1和R-1在空中不同距离处(距爆心5 m内)的平均TNT当量分别为1.4和1.09;在爆心12.6 m处,H-1和R-1的地面冲击波超压TNT当量分别为1.25和1.025。
In this work,static detonation tests were conducted to study the detonation characteristics of two kinds of composite thermobaric explosives with different components and charging processes.The overpressure of shock wave,fireball diameter and the surface temperature parameters of the fireball were measured and compared with TNT with the same mass.The results showed that,with the same charge mass(2 kg),the shock wave overpressure adopting H-1 charge(HMX/Al/binder)was higher than that of R-1 charge(RDX/AP/Al/binder).Yet,the surface temperature of the fireball formed after the detonation of the R-1 explosive was higher,and the high-temperature duration was longer than that of H-1.Moreover,according to the calculation results on the basis of overpressure value,the average TNT values of the H-1 and R-1(within 5 m away from the detonation center)were 1.4 and 1.09,respectively.At the position of about 12.6 m away from the detonation center,the overpressure TNT values of the ground shock wave with H-1 and R-1 explosives were 1.25 and 1.025,respectively.
