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.
