Abstract:

A summary of results of experimental studies of combustion of AP- polymer sandwiches is reported. Most recent results are combined with those of a previous report, and mechanistic interpretations are presented. On the basis of these interpretations, a detailed qualitative model of the combustion zone structure is advanced, and examined for consistency with results of this and other studies. The results are tested by prediction of a singular feature of the burning of propellants, and propellant tests are reported that confirm the predictions. The results indicate that the combustion of AP-hydrocarbon binder propellants involves closely coupled, three-dimensional interactions among several regions of the flame complex. These features are important to understanding both steady state and oscillatory combustion.
