Experimental Study of the Aluminized Explosive RDX/Al Explosion Under Water

The explosive effect is greatly impacted by the aluminum content and condensability of the medium enclosing the aluminized explosive heavily.In this paper, the underwater explosive energy's effect correlated with the aluminum content and the characteristic parameters versus various distance for the under water shock wave of the aluminized RDX/Al explosive is studied through underwater explosive experiment. The result shows that the increase of shock wave energy resulting from the aluminum burning in the production of detonation weaken pressure attenuation. The energy is maximal while the aluminum content is equal to 20 wt% for the shock wave in water. The shock wave transmission rule in water for the certain aluminum content aluminized explosive is consistent with explosive similarity. Through the relations of the scaled shock wave characteristic parameters and the scaled distance function, the form of exponential function can be obtained.
