STUDY OF THE COMBUSTION MECHANISM OF AN-BASED PROPELLANTS
RÉSUMÉ
This paper discusses results obtained in studying the combustion mechanism of ammonium nitrate (AN)-based propellants. For this purpose, a row of progressively complicated AN-based systems: AN/catalyst; AN/catalyst/binder; AN/catalyst/binder/ammonium perchlorate (AP); and AN/catalyst/binder/AP/Al has been studied. It was shown that successive addition of AP and Al to the binary mixture of a catalyzed AN/binder yields a regular increase in the burning rate, accompanied by a small change in the pressure exponent. On the basis of flame structure investigation, it has been determined that the surface temperature of catalyzed AN as well as AN-based propellants is controlled by the dissociative evaporation of the salt. Analysis of obtained results allows for the suggestion of a combustion mechanism for AN-based propellants, which is based on the leading role of heat release in the condensed phase.
