模拟标准物质测定多参数液体推进剂

Determination of multi-parameter liquid propellant by simulating standard substance

基于液体推进剂组分/杂质含量与特征吸光度值的线性关系,以特种光学玻璃为材料,确定模拟标准物质的标准基片及参考基片的特征吸光度值,同时模拟液氧中乙炔,绿色四氧化二氮中一氧化氮、铁离子、氯离子及无水肼中铁离子、氯离子的含量,并以此为标准建立工作曲线,测定液氧中乙炔等6种液体推进剂组分/杂质含量。

Based on the linear relationship between component/impurity content in liquid propellants and characteristic absorbance values,using the specialty optical glass as material,the standard substrates of the simulating standard substance and the characteristic absorbance values of the reference substrate were confirmed.Meanwhile the content of acetylene in liquid oxygen,the content of nitrogen monoxide,ferric ion,chloride ion in the green nitrogen tetroxide,and the content of ferric ion,chloride ion in anhydrous hydrazine were simulated.The working curves were established by using above-mentioned simulation content as standards,and the component/impurity content in six kinds of liquid propellants including acetylene in liquid oxygen was determined.
