Air-Blast Characteristics of an Aluminized Explosive

Abstract

Air-blast characteristics of an aluminized explosive (RDX/ammonium perchlorate/ aluminum/binder 20/43/25/12) were investigated . The TNT-equivalent weight factor of this explosive was experimentally determined as a function of peak pressure in the pressure range of from 0-7 to 120 psi. This factor was 0.9 for pressures over 10 psi (incident-wave region) and increased to 1.2 for pressures lower than 10 psi (Mach-wave region). It is believed that this increase in the TNT-equivalent weight factor in the low pressure region should be attributed to slow energy release from oxidation reaction of aluminum powder added in the explosive.
