Abstract

In this paper, in order to make the micro-high explosive train more integrated and reliable, the motion state of flyer driven by two-point initiation copper azide (primary explosive) is studied, and a metal film bridge for two-point ignition is designed. The simulation tests of explosion model and metal bridge model are carried out by AUTODYN and COMSOL respectively. The results show that: 1) the appropriate two-point initiation distance can make the flyer obtain sufficient kinetic energy in a shorter acceleration chamber; 2) the parallel metal bridge structure has more intense temperature rise and higher initiation instantaneity.
