Paper Abstract

We studied a new optics-ammunition mechanism by an adiabatic heating model of exploding wires on strong pulsed current and a model of shock waves inspired by exploding wires blasting in inert gases. A Pspice simulation code for engineering applications and an improved MHD (Magnetohydrodynamics) computation code for physics research have developed in this paper. The computation results indicate that, firstly, plasma radiation intensity increased by Machnumber of shock waves, and in all insert gases, argon's Mach-number of shock waves is highest. Secondly, silver is the best in common metal materials, and the exploding time and current peak is about linear with the number of wires. Thirdly, the parameters of wire including the diameter, length and number will influence the exploding performance deeply; Fourthly, Pspice computation is an experiential method, but the result has direct guiding sense for engineering design. Fifthly, the improved 1D single temperature MHD model can be used in multi-wire paralleled electricity exploding computation very well, and computation results agree with the known experiment data and are important to the study of strong pulsed IR optics-ammunition.
