| 中文摘要: |
| 燃油温度升高会导致燃油结焦，而燃油结焦对飞行器会带来极大危害，因而抑制燃油结焦是亟待解决的问题。在实际应
用中，针对不同的结焦机理，可采取不同的抑制方法。介绍了燃油结焦的机理，综述了国内外关于航空煤油特性的影响因素的相关
试验情况。结果表明：温度对燃油结焦影响最大，由于温度的不同，结焦机理也会发生变化；而压力、流动方式对结焦的影响很小。故
通常采用溶解氧含量、材料表面处理及使用添加剂来抑制结焦 |
| 英文摘要: |
| The rise of fuel temperature will lead to fuel coking, resulting in great harm to aircrafts. Thus, the problem of fuel coking
suppression should be solved urgently. Various suppression methods can be adopted for different coking mechanisms in practical
application. The mechanism of fuel coking was introduced, and the situation of relevant experiments on the influencing factors on aviation
kerosene characteristics at home and abroad was summarized. The results show that the temperature has the greatest effect on fuel coking,
and the coking mechanism changes due to different temperatures. The pressure and flow pattern have little effect on fuel coking. Therefore,
the fuel coking is usually depressed by the dissolved oxygen content, the surface treatment of materials and the use of additives |
