CONTROL CIRCUIT FOR FIRING A LOW-RESISTANCE FUSE

摘要

For small calibre projectiles the electrical energy needed for igniting a low-ohm ignition capsule is stored in a supply or ignition capacitor which, upon firing of the projectile, is charged by a current generator. To ensure that during charging of the supply capacitor upon firing of the projectile, the ignition capsule does not prematurely ignite, there are provided safety circuits, in particular a static blocking circuit, a dynamic blocking circuit and a static delatching circuit.
