ABSTRACT:
The invention relates to a low-vulnerability explosive munitions element comprising a casing containing a multicomposition explosive charge, the innermost layer of which is a composite explosive comprising a filled polyurethane or polyester polymer matrix, the filling of which contains more than 40% by weight of organic nitrate explosive, and the peripheral layer of which is a pyrotechnic composition of the family of composite solid propellants comprising a filled polyurethane or polyester polymer matrix the filling of which contains at least one mineral oxidant and less than 10% by weight of organic nitrate explosive. The blast and/or bubble effect produced is close to that produced by the much more-vulnerable charge of monocomposition composite explosive of equivalent mass. The invention also relates to a method for obtaining a blast and/or bubble effect by releasing in the casing of an aforementioned munitions element according to the invention, and then rupture of the casing. The release of gas is obtained by detonation of the innermost layer and then reaction without detonation of the peripheral layer.
