Abstract (en)

[origin: EP0477090A1] 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>
