两种含铝炸药作功能力与JWL状态方程研究

Study on Work Ability and JWL Equation of State of Two Aluminized Explosives

采用圆筒试验方法研究了ROTL905、TRAL含铝炸药的作功能力,并将试验结果与JOB9003、TATB炸药进行了比较。利用圆筒试验数据计算了含铝炸药JWL状态方程参数。研究结果表明:与JOB9003、以TATB为基的PBX炸药相比,ROTL905、TRAL含铝炸药由于含有铝粉等慢反应成分,初始加速度小、衰减慢、后续作功能力强,圆筒膨胀到距离为6.5mm和9.9mm时,其加速能力已超过JOB9003炸药。

The cylinder tests on ROTL 905 and TRAL aluminzed explosives were carried out. The results were analyzed and compared with that of JOB 9003 and TATB explosives. The parameters of JWL equation of state for detonation products of ROTL 905 aluminized explosive were calculated. The results show that because of containing slow reaction element Al,at the earlier period of copper wall expansion,the acceleration of ROTL 905 and TRAL aluminized explosives is far smaller than that of JOB 9003 explosive ,whereas the former decreases slowly. At about 6.5 mm and 9.9 mm,the acceleration of the two aluminized explosives exceeds that of JOB 9003 explosive . It also shows the aluminized explosives have stronger continuous working ability.
