It is shown that this reaction scheme follows the Shimizu hypothesis for pyrotechnic strobe combustion; both decay stages are temperature dependent with only the second generating a significant quantity of heat. The model is derived from the combustion reaction between ammonium perchlorate and fine magnesium powder although reaction of other strobe compositions is expected to proceed in a similar manner. It will be shown that the effects of additives, such as potassium dichromate as a frequency modifier, can be investigated without explicitly including them in the model. The model is therefore a first step towards a useful design tool for developing compositions with specific strobe characteristics.<br \/> <strong><br \/> Keywords:<\/strong> thermokinetic model, strobe composition, Shimizu hypothesis, bifurcation theory, two-stage decay<\/p>\n<hr \/>\n<p><strong>Ref:<\/strong> JPyro, Issue 27, 2008, pp42-49<br \/> (J27_42)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Matthew L.
