Gliding arc plasma on-duty flame head of aero-engine combustion chamber

The invention discloses a gliding arc plasma on-duty flame head of an aero-engine combustion chamber. A fuel nozzle is located in a cathode sleeve. A first-stage cyclone sleeves the cathode sleeve; and an anode venturi tube sleeves the first-stage cyclone. A second-stage cyclone is arranged between a flow guide sleeve and a venturi tube mounting seat. The rotational flow blades of the first-stage cyclone are uniformly distributed on the outer circumference of an inner cylinder, and the direction of the air outlet end of each rotational flow blade of the first-stage cyclone is opposite to that of the air outlet end of each rotational flow blade of the second-stage cyclone. The gas source of each stage of cyclone is combustion chamber inlet gas, and external air entraining is not needed; and the two stages of rotational flow blades with the air outlet ends opposite in direction generate reverse rotational flow, fuel oil atomization is promoted, atomized and cracked fuel oil, air and active particles generated b
