NONLINEAR TRANSIENT BURNING OF COMPOSITE PROPELLANTS: THE EFFECT OF SOLID PHASE REACTIONS

The phenomenon of transient burning of solid propellants is a topic which still contains a large number of questions. In this paper the transient burning of AP composite propellants is calculated within the QSHOD approach (Quasi Steady gas phase, Homogeneous One-Dimensional condensed phase). This paper focuses on the effect of the condensed phase on the transient burning of solid propellants by showing the effect of temperature dependent thermal properties, phase transitions and chemical reactions in the solid phase. Nonlinear effects are conserved, as governing equations are solved numerically.
