The copper cylinder tests were carried out to explore the effects of the aluminum contents on the performances of aluminized RDX-based explosives.In the tests, the outer diameter of the copper cylinder was 50 mm and the mass fractions of aluminum in the three RDX-based explosives were 0, 15% and 30%, respectively.In the three explosives tested, the acceleration ability of the explosive with the aluminum mass fraction of 15% was highest.However, the acceleration ability of the explosive with the aluminum mass fraction of 30% was lower than that of the pure RDX.The Gurney formula was used to analyze the reaction process of aluminum with detonation products in the aluminized RDX-based explosives.About 49% aluminum by mass had reacted in the explosive with the aluminum mass fraction of 15% at 34 μs, while in the explosive with the aluminum mass fraction of 30%, only about 21% aluminum by mass had reacted.And the reaction time of aluminum powder with the size of 10 μm was 50-200 μs.
