Ignition of model composite propellants by a single particle heated to high temperatures

This paper describes the technique and results of an experimental study of the ignition of condensed materials (model composite propellants) by a hot single metal particle. The dependence of the ignition delay of condensed materials (CMs) on the initial particle temperature is investigated. The mechanism of interaction of a single particle heated to high temperatures with unmetallized and metallized CMs is analyzed. It is found that the presence of a metallic filler in the CM changes the absolute values of the ignition delay and the relative characteristics of their spread.
