Abstract

Abstract

A new non-ideal explosive was obtained by adding aluminum fiber to RDX.Pressure-time curves were measured in different regions by underwater explosion experiments of aluminum fiber explosive and RDX.Peak pressure, impulse, shock wave energy, bubble impulsion period and bubble energy were obtained by analyzing the curves.The peak pressure of the new explosive is lower than that of RDX in same regions.The shock wave impulse becomes lager and the distance does not much affect the difference.Compared with RDX, the specific shock wave energy of the new explosive decreases by 2%~5.2%, the specific bubble energy rises by 9.4%~23.36%, the specific explosion energy increases averagely by 3.5%.The specific bubble energy is 55%~60% of explosion energy, which is higher than the ratio 50%~53% of RDX.The specific explosion energy is 74%~84% of explosion heat, which is lower than the ratio 89%~95%of RDX.
