Experimental investigations of the burning wave structures of HMX and RDX were carried out by microthermocouple technique at a pressure of 1-70 (90) atm. Burning-surface temperature, heat release in solid, heat feedback from gas to solid, and heat-release rate in gas near the surface were obtained. The data obtained show that in the condensed phase of combustion waves of nitramines, evaporation, and thermal decomposition occur simultaneously, with heat release in the solid being negative at p < 5-10 atm and positive at p > 5-10 atm. Activation energies of HMX and RDX decomposition in combustion waves were evaluated. Published results of investigations of the thermal burning wave structures of double-base propellants (DBF) containing HMX and various catalysts were used to establish the influence of additional nitramines on the unified dependencies of simple DBFs. It was found that the gasification law, heat-release law in the solid, and heatfeedback law do not change, but that the dark zone laws and dependencies for temperature sensitivities change significantly when HMX is added. © 1995 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
