Acceleration Abilities of Combined Explosive Charges Containing Dispersed Aluminum in a Thin Peripheral Layer

Abstract

An X-ray pulse video recording method is used to study the acceleration ability of coaxial combined explosive charges containing dispersed aluminum in a thin peripheral layer as compared with charges containing a uniformly distributed aluminum additive and charges with no additives. The significant influence of the burnout of detonation products on the acceleration ability of explosive charges containing dispersed aluminum is confirmed. It is shown that aluminum in a composition with explosive charges burns out because of reacting both with detonation products and ambient air, including in a rarefied environment.
