A numerical calculation method for analyzing combustion wave structure of solid rocket propellants has been designed. Using this method we can get the detail information of chemical reactions in the condensed phase of homogeneous solid propellants.We believe that there would be no condensed gas interface, and the surface temperature would be no meaning.From results of combustion waves of a modified double base propellant,we believe that in solid phase there would be multi stage reaction mechanism, and that the reaction mechanism would be the same in condensed phase at different pressures, only the reaction heat release value would be not same.We also believe that Π thermocouple would be insuitable for measuring combustion wave of nonhomogeous propellants.
