Initiation of Explosives by Exploding Wires. Vii. Effect of Energy Termination on the Initiation of PETN by Exploding Wires

摘要

Artificial termination of the capacitor discharge pulse to gold and platinum bridgewires shows that the arc phase is largely unnecessary for effecting detonation in PETN. The time of energy termination is dependent upon when the PETN reaction becomes self propagating. Two modes of initiation by exploding wires are suggested by the experiments: Pure shock, and the combination of shock and thermal energy inputs. Energy input after burst is superfluous for the shock initiation mode but necessary when initiation is largely thermal. (Author)
