喷气燃料中水含量测定技术研究

Study on Determination of Water Content in Jet Fuel

本文介绍了喷气燃料中超标水含量对飞机运行产生的影响;介绍了新兴的测定手段——温度滴定法,总结对比了几种水含量测定方法的优缺点与适用范围;总结了卡尔费休法和温度滴定法测定实验中的注意事项。得出结论:两方法对3#喷气燃料微量水含量测定结果具有一致性;并对后续该研究中的发展方向提出建议。

In this paper introduces the influence of excessive water content in jet fuel on aircraft operation. The operation requirement and error correction method of Karl Fischer method for jet fuel water content determination are introduced. A new method of measuring called temperature titration is introduced, the advantages and disadvantages of several methods for determination of water content were summarized and compared. The points needing attention in the experiments of Karl Fischer method and temperature titration method were summarized. It is concluded that the results of the two methods are consistent for the determination of trace water content of 3# jet fuel, and suggestions for the future development of the research were put forward.
