Abstract
The invention concerns the field of ammunitions equipped with their fuze, found on the battlefield. Such ammunitions represent a major pyrotechnic risk. The problem consists in destroying the fuze so as to be able to dismantle said ammunition. The method consists in placing said ammunition (1) in a closed chamber (5) to carry out at least once the following cycle: depressurizing the chamber (5), dissolving the fuze (2) of the ammunition (1) with a liquid corrosive agent, drawing off the gaseous effluents towards an auxiliary chamber (7), reopening the chamber (5) after dissolving the fuze (2), removing the ammunition (1), recovering the mixture resulting from the attack of the fuze (2) by the liquid corrosive agent (6) and treating it by pyrolysis.
