Combustion Mechanism and Unsteady Burn-Rate Predictions of New Modern Polymer-Oxidizer Mixtures

Abstract

Fundamental investigations of physico-chemical mechanisms of combustion were performed for new mixtures of HNIW (2,4,6,8,10,12-hexanitrohexaazaisowurtzitane) and HMX with modern energetic binders (AMMO-BAMO)+burn-rate modifier and (BAMO-THF). Burning wave structures, burning rates and main burning wave parameters were received by experiments and processing. Leading stages and macrokinetics of gasification of solid phase were established. Main features of the combustion mechanisms of the mixtures were formulated. A closed system of predictions of erosive and pulsating burning rates, typical for rocket motors, was created. The system includes obtaining: erosive burning rates, burn-rate response functions on pressure and gas velocity pulsations. The obtained corps of the characteristics describes burning rate behavior of the mixtures inside rocket chamber. Conclusions were made about combustion mechanisms of the studied mixtures under stable and pulsating external conditions, and recommendations.
