Effect of Powder Compaction Variables on the Performance of a Pyrotechnic Igniter

摘要

The compaction of the pyrotechnic powder against a bridgewire in an igniter is very critical to performance. The density of the compact at the bridgewire interface can be effected by the powder characteristics, environment, surface finish and configuration of the compact holder and the loading process. Some of these parameters have been evaluated and the effect determined on the bridgewire-powder interface as well as the initiation performance. (ERA citation 04:001290)
