被动式FTIR遥感掺纳米材料固体推进剂的燃烧火焰温度

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6 nm CuO，56 nm Fe₂O₃,16 nm NiO粒子及相应的普通金属氧化物。FTIR仪器分辨率为1 cm-1。利用燃烧产物中H₂O分子在2.75 μm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NiO粒子的固体推进剂的燃烧火焰温度分别为3 089，3 193和3 183 K，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。

Remote Passive Detection of Flame Temperature of Solid Propellant Adulterating Nanoparticles

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 microm. The results of the flame temperature of the solid propellants adulterating nano-scale CuO, Fe2O3 and NiO are 3089, 3193 and 3183 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.
