INITIATION OF EXPLOSIVES BY EXPLODING WIRES. I. EFFECT OF CIRCUIT INDUCTANCE ON THE INITIATION OF PETN BY EXPLODING WIRES
Abstract
The effects of circuit inductance and bridgewire length on the initiation of PETN by exploding platinum wires were investigated. A capacitor discharge was used as the energy source. Oscillograms of current and voltage coincident with smear camera records were used to interpret the wire explosion and initiation processes. Increasing circuit inductance lowers the probability of producing detonation in PETN by an exploding wire. Secondary current pulses have little effect on whether or not detonation results. For effective initiation the bridgewire length should be chosen to eliminate current dwell.
