An Investigation of Insensitive Electric Initiators. I. 1-amp/1-Watt No-Fire Initiator

摘要

The report describes an approach for making insensitive electric initiators. Inefficient heating of the bridge element is the key change. Various bridge heating element geometries and bridge heating element materials, with normal lead styphnate and lead azide loaded on the element were investigated. Initiators capable of passing at least 1-ampere of current and/or absorbing 1-watt of power for 5 minutes without initiating, have been developed. (Author)
