Blast treatment method and blast treatment device

Abstract

A blast treatment method enables easy and safe blast treatment of ammunition having propellant provided with a warhead having a bursting charge and a propulsion unit having a propellant. Comprised are a first explosive arrangement step of arranging a first explosiveon the outside of a warhead; a second explosive arrangement step of arranging a plurality of explosive membersincluding a second explosiveon the outside of the propulsion unit; a warhead blast step of causing detonation of a bursting chargeby detonation of a first explosive, thereby blasting the warheadand a propulsion unit treatment step of causing deflagration of a propellantby detonation of the second explosive, thereby performing combustion of the propulsion unit; the first explosiveis arranged at a position covering the periphery of the warhead, a high-pressure field is generated on the periphery of the warheadby detonation of this first explosive, and by means of this high-pressure field, divergence of detonation energy of the bursting chargeto outside this high-pressure field is suppressed, and moreover the explosive membersare arranged at mutually separated positions whereby divergence of the combustion energy of the propellantto the outside from the explosive membersis allowed, by which detonation of the propellantis suppressed.
