LOW-VULNERABILITY PYROTECHNICAL CHARGE

摘要

The invention relates to pyrotechnical charges comprising a fragment generator (10, 20, 50) and an explosive (12, 22, 42, 52) having an outer surface divided into n sectors (S1, S2,..Si,...Sn), each sector including multiple kq priming points (p11, p12,... pxy,...pkq) for the explosive, k and q being integers greater than 1. The multiple kq priming points for the explosive are connected by priming lines (Cda, Cdb, Iga1, Igb1, Iga2, Igb2, Iga3, Igb3) defining, for each sector, at least two partial imbedded networks (Rai, Rbi) for the synchronous priming of the multiple kq priming points, each of the synchronous priming partial networks being connected to a respective partial network detonator (Dtai, Dtbi).
