Abstract
We present a study of one-dimensional flame structure of combusting solid propellants that focuses on the effects of variable material properties. A nonlinear heat equation is derived for a burning thermo-elastic solid with temperature-dependent specific heat, thermal expansion and thermal conductivity coeffcients. It is then solved for different modelling approximations both analytically and numerically. Explicit expressions are derived for the regression rate of the propellant surface as functions of surface temperature. The full structure of propellant flame is studied to identify the influence of temperature dependent material properties on the regression rate, surface temperature and flame stand-off distance. Results are displayed for HMX and compared to experimental data and to numerical simulation with fair success.
