中文摘要：

利用布鲁克公司生产的OPAG 33型傅里叶变换红外光谱仪（Fourier Transform Infrared Spectrometer,FTIR）对固体推进剂燃烧火焰的温度进行了研究。在仪器的分辨率为4 cm（-1）、测试距离为20 m的条件下,实时测得了高能硝酸酯增塑聚醚（Nitrate Ester Plasticized Polyether Propellant,NEPE）固体推进剂燃烧火焰的红外发射光谱图。利用燃烧产物中HCl气体分子的发射光谱精细结构谱线计算了NEPE固体推进剂羽流的温度。实验结果表明,利用被动式遥感FTIR光谱仪可对固体推进剂的燃烧温度进行快速实时的非接触式测量,是一种有效的研究手段。

英文摘要：

The temperature of solid state propellant combustion flame is studied by a Bruker OPAG33 Fourier Transform Infrared Spectrometer（FTIR）.The infrared emission spectra of Nitrate Ester Plasticized Polyether Propellant（NEPE） solid propellant are measured with a resolution of 4 cm-（-1） at a testing distance of 20 m in real time.The temperature of NEPE propellant plume is calculated by using the fine structure emission spectral lines of HCT gas molecules released in combustion products.The experimental results show that a passive remote sensing FTIR can measure the temperature of solid propellant plume rapidly and non-contactly in real time.It is an effective means for research.
