摘　　要：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.
