The burning temperature of single-based (H100 and H130),SF (SF-3),modified double-based propellants (171-25 and GT) were calculated and measured at constant pressure. The difference between adiabatic flame temperature approximation calculationresult and measured result was compared. The calculation results are consistent with experimental results,the maximum flame temperatures of H130 and SF-3 propellant are 2215 K,2230 K. As the candidate of hot source,the double-based propellant is better than the single-based propellant. The colorimetric temperature measurement can not reflect the accurate temperature of modified double-based propellants.
