Abstract

Abstract

In the present work, the parameters of shock wave and secondary pressure wave with different aluminum powder content and particle size of CL-20-based aluminized explosives were measured by underwater explosion testing, the shock wave energy and bubble energy were calculated, and the explosion reaction mechanism of CL-20-based aluminized explosives was analyzed. The results show that the shock wave energy and the bubble energy of the underwater explosion represent the energy distribution in the early detonation period and the secondary reaction period, with only a minor portion of the aluminum powder participating in the early detonation period. The secondary pressure wave formed by the bubble pulsation can describe the effect of the aluminum and detonation products on the secondary reaction. The amount of the aluminum content has a significant influence on the process of the secondary reaction and, while the aluminum particle size has little effect on the initial shock wave parameters, shock wave energy and bubble energy, its effect is great on the secondary reaction rate of the aluminum power and detonation products.
