摘　　要：应用被动式遥感FTIR,分别对掺入纳米级金属氧化物、掺入同种材料普通金属氧化物及无掺入物的固体推进剂的燃烧火焰温度进行了测量。固体推进剂的主要成分为硝化棉和硝化甘油。掺加物分别为6nm CuO,56nmFe2O3,16nm Ni O粒子及相应的普通金属氧化物。FTIR仪器分辨率为1cm-1。利用燃烧产物中H2O分子在2.75μm处的基带发射光谱精细结构,根据分子转振光谱测温法,计算出燃烧火焰温度。结果表明,掺有纳米级CuO,Fe2O3和Ni O粒子的固体推进剂的燃烧火焰温度分别为3089,3193和3183K,此温度与掺入同种材料的普通金属氧化物和无掺入物的固体推进剂的燃烧火焰温度无明显差别。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-seale 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 2.75μm. The results of the flame temperature of the solid propellants adulterating nano-seale CuO, Fe2O3 and NiO are 3089, 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.
