Open publisher page 0 citations

Abstract

The blast shock wave pressure and the bubble pulse period of RS211,HL-1,HL-2 and TNT explosives were measured,and then the peak pressure,shock wave impulse,shock wave energy and bubble energy were obtained.The experimental results showed that in the studied range,the shock wave energies and the bubble energies of the three aluminized explosives were about 1.20～1.35 and 1.50～2.30 times more than TNT explosive,respectively.The analysis results indicated that the aluminum powder added to explosives can enhance underwater explosion power of the explosives.
