The Effects of Ultrahigh-Pressure Waterjet Impact on High Explosives

Abstract

Alliant Techsystems tested the effects of ultrahigh-pressure waterjet impact on both PETN and TNT explosives. The pressure of the test was approximately 1 GPa (150 ksi) since this pressure generates the maximum water velocity, is the pressure limit of available equipment, and is the pressure at which water freezes at 25 deg C (75 deg F). PETN and TNT were chosen as representative of the range of explosives used in the industry. PETN is the most sensitive common secondary explosive, while TNT is a low-sensitivity explosive that makes up more than two-thirds of the military explosives used. The results of the tests show that neither PETN nor TNT reacts when impacted by waterjets at these pressures.
