Abstract：The flame temperature of three kinds of solid propellants was measured by passive remote sensing FTIR with the resolution of 1 cm-1. These three kinds of solid propellants are adulterate nano-scale metal oxide particles, adulterate normal metal oxide particles，and propellant without any adulterations. The main components of the solid propellant are nitrocellulose and nitroglycerin. The metallic oxides，including 6 nm CuO, 56 nm Fe2O3,16 nm NiO，and correspondingly the normal particles，were adulterated into the solid propellants respectively. The flame temperature was calculated through the fine structure of the emission fundamental band of H2O at 2.75 μm. The results of the flame temperature of the solid propellants adulterating nano-scale CuO, Fe2O3 and NiO are 3 089, 3 193 and 3 183 K, respectively. The temperatures of the three kinds of solid propellants were compared, and it was shown that there is no obvious difference in the flame temperature among the three kinds of solid propellants.
