In view of the difficulty of kerosene-air detonation faced by the application of rotating detonation to aviation engines, in order to improve the kerosene detonation activity, the atmospheric pressure gliding arc plasma is used to conduct secondary adjustment of the pre-combustion cracking products. The results show that the components with larger molecular weight in the pre-combustion cracking products, such as ethylene and methane, can be cracked into highly active species of hydrogen and acetylene by gliding arc plasma. With the increase of the fuel ratio of pre-combustion cracking, the plasma has a more significant effect on the adjustment of high active components. However, as the flow rate of the cracking gas treated by plasma increases, the adjustment effect is obviously reduced.

针对航空发动机应用旋转爆轰所面临的煤油-空气爆轰困难，为提高煤油的爆轰活性，采用常压滑翔电弧等离子体对预燃裂解产物进行二次调节。结果表明，燃烧前裂解产物中分子量较大的组分，如乙烯和甲烷，可以通过滑动电弧等离子体裂解成氢气和乙炔等高活性物质。随着预燃裂解燃料比的增加，等离子体对高活性组分的调节作用更加显着。但随着等离子处理裂解气流量的增加，调节效果明显降低。
