Abstract:To study the relationship between the burning rate and the characteristic value of combustion wave,the combustion wave structure of double-base propellant with low burning rate and low flame temperature were obtained by using the technology of imbedded minimized thermal couples into propellant,and the experimental data were calculated and the characteristic value of combustion wave,the surface temperature,the dark zone thickness,the temperature grades of condensed phase and gas phase fizz zone, were obtained. Burning rate of propellants without catalysts increases with the surface temperature increasing,and the surface temperature of propellants with catalysts is higher than that of propellants without catalysts. Flame temperature enhances with increase in pressure, and there is not necessary relationship between flame temperature and burning rate. Results show: the relationship between the burning rate of the said double-base propellant with low burning rate and low flame temperature and the characteristic value of combustion wave is rather complex,and there are linear and non-linear relationships when combustion performance changes. The reason is that combustion wave structure is changed with catalysts.
