The quantitative measurement of jet fuel additives in the field is of interest to the Air Force. The "smart nozzle" project was designed as a state-of-the-art diagnostics package attached to a single-point refueling nozzle for assessing key fuel properties as the fuel is dispensed. The objective of the work was to show proof of concept that a layer-by-layer thin film and long period grating fibers could be used to detect the presence of water in jet fuel. The data for the nafion/PDMA film and a long period grating fiber is a combination capable of quantitative measurement of water in kerosene. The average response (spectral loss wavelength shift) to the kerosene sample ranged from -6.0 for 15 ppm to -126.5 for 60 ppm water. The average calculated value for the check standard was 21.71 and ranged from 21.25 to 22.00 with a true value of 22.5 ppm water. Potential interferences were observed and are judged to be insignificant in real samples.
对喷气燃料添加剂进行现场定量测量是美国空军感兴趣的事情。“智能喷嘴”项目设计为一种最先进的诊断组件，连接到单点加油喷嘴上，用于在燃料加注时评估关键燃料特性。这项工作的目的是证明一种逐层薄膜和长周期光栅光纤可用于检测喷气燃料中是否存在水的概念。关于全氟磺酸离子交换膜/聚二甲基丙烯酸甲酯薄膜和长周期光栅光纤的数据是一组能够对煤油中的水进行定量测量的数据。对煤油样品的平均响应（光谱损耗波长偏移）范围从15 ppm水时的-6.0到60 ppm水时的-126.5。检查标准的平均计算值为21.71，范围在21.25至22.00之间，水的真实值为22.5 ppm。观察到了潜在干扰，并且判断其在实际样品中不显著。
