Abstract: Experimental data on the combustion velocity of hexogen [RDX, triethylene trinitramine] at various initial temperatures were analyzed considering the temperature-dependence of the density, the heat capacity and the solid-phase reaction kinetics; it is shown that the critical temperature, like the ignition temperature, is the boiling point. Analytic functions were obtained that reproduce the experimental data on the hexogen combustion velocity, the pressure and temperature coefficients of the mass combustion velocity, the derivative of the pressure coefficient with respect to temperature, and the derivative of the temperature coefficient with respect to pressure in the range of 0.098–4.9 MPa and initial temperatures of 293–453 K.
