The less vulnerable of explosive munition and advantages of priming of a composite explosive charge is not very sensitive.

摘要

The subject of the present invention is an element which is invulnerable to explosive ammunition. It consists of an envelope 1, preferably metallic, containing a charge 2 of a non-sensitive composite explosive E and, as an ignition relay, a plane-wave generator 3. This generator consists of, on the one hand, a cylindrical-conical cap 7 made of a composite explosive A, the large base area having a diameter d greater than the critical diameter of the explosive E and the hollow 8 of this cap 7 being filled with a composite explosive B and, on the other hand, of a booster made of a composite explosive C with a thickness e greater than 0.1d, the detonation pressure of the explosive C being higher than that of the explosive E. The detonation sensitivity index according to the sensitivity test with detonation behind a barrier lies between 90 and 200 cards for the explosives A, B and C and below 90 cards for the explosive E. The invention also relates to the process for the ignition of the charge 2 by the generator 3. IMAGE
