Study of Combustion Mechanism of New Polymer/Oxidizer Mixtures

Abstract

Combustion mechanisms of mixtures of CL-20 (hexanitrohexaazaisowurtzitane, or, HNIW) with active binder, plastified polyurethane (PUNE), 70:30, were investigated simultaneously with those of mixtures of PUNE/HMX, 30/70. Temperature profile and surface temperatures in combustion waves of the mixtures were measured at pressures 0.1-10 MPa and sample temperatures -100, 20 and 90 deg C. Burning rates, heat release iii solid, heat feedback from gas to solid, heat release rate in gas, zone temperatures and sizes, macrokinetics of gasification, leading stages, sensitivities, criteria of stable combustion and reponse functions - were found. Conclusions about peculiarities of combustion mechanisms of the mixtures are presented. Recommendations for future works were formulated. Preliminary results for mixtures of (BAMO-AMMO)/CL-20, 20/80, were obtained.
