The combustion processes of solid propellants and rocket chamber Flows are being analyzed in terms of more complete flame models and fluid dynamics models. The flame structure, surface processes, and liquid layer decomposition of a cyclic nitramine e.g., RDX have been modeled. The model includes the partial decomposition of the nitramine molecule in the liquid phase, surface gasification, gas phase decomposition, and oxidation of formaldehyde. Several propellants e.g., nitramine composite and nitrocellulose-based propellants produce flame zones which extend well into the main chamber flow field. An analytical model is being developed that considers the effects of chemical reactions i.e., extended flame zones in the main chamber flow on the acoustic response of solid rocket motors. Author
