Influence of anti-ice agent on the usability indexes of aircraft jet fuel

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.
