| 目的 为确保飞行器喷气燃料使用可靠性，研究不同防冰剂添加量对飞行器喷气燃料的主要使用性能指标的影响及其影响规律。方法 立足用于喷气燃料的乙二醇甲醚防冰剂，通过研究喷气燃料使用指标的检测结果与相应防冰剂含量的对应关系，结合理论分析，得出具体的影响规律。结果 随着防冰剂添加量的增加，喷气燃料使用性能指标中的闪点和馏程中的初馏点降低，密度增大，水反应试验评级水平提高，其他馏程指标和运动黏度基本未发生变化。其中，闪点和水反应试验结果变化较显著。结论 当喷气燃料中防冰剂的添加量在要求范围时，随着防冰剂添加量的增加，密度指标产生了正向响应，闪点和初馏点指标产生了负向响应。为保证喷气燃料的使用安全，应严格控制防冰剂的含量，尤其是不能过量。 |

| Abstract: |
| Objective In order to ensure the use reliability of aircraft jet fuel, this study investigates the effect and its influencing rules of different contents of anti-ice agent on the main usability indexes of jet fuel based on glycol methyl ether as the anti-ice agent for jet fuel Method Based on the ethylene glycol methyl ether used for jet fuel as anti-ice agent, specific influencing laws were obtained by studying the correlation between the detection results of jet fuel usability indexes and the corresponding anti-ice agent content, combined with theoretical analysis. Result The experimental results showed that the flash point and initial boiling point of jet fuel decrease with the increasing addition of anti-ice agent. On the contrary, the density of jet fuel increased and water reaction test rating improved with the increasing addition of anti-ice agent. The influence on the flash point and water reaction test are more obvious. The other indexes have hardly changed. Conclusion With the increasing addition of anti-ice agent increases, density has a positive response, while the flash point and initial boiling point have a negative response as long as the addition of anti-icing agent in jet fuel fits the requirement. In order to ensure the use reliability of jet fuel, the addition of anti-ice agents should be strictly controlled, especially not overdosed. |
