Mechanical fuse with several circuits for test projectile - has separated and insulated fuse charges ensuring functioning even if damaged

摘要

The fuse for a training projectile has a number of independent initiation circuits. Each circuit has an ampliying charge with transmitting explosive charge. The training projectile is reliably blown apart even if the amplifying charge is damaged to a certain extent. The amplifying charge consists of at least two charges independently initiated by separate ignition circuits. These charges are kept apart and thermally insulated. A metal foil separates amplifying charges from transmission charges. The amplifying charge can consists of three sector shaped preformed sections in one unit.
