Embodiment 1
[0046] Such as Figure 1 to Figure 5 The shown aero-engine plasma jet igniter based on self-bleed air includes an outer tube 4, an insulating inner tube 5, a conductive copper tube 6, a cathode 7 and an anode 8, and the outer tube 4 is arranged above the anode 8 , the lower end of the outer tube 4 is fixedly connected to the upper end of the anode 8, the insulating inner tube 5 is set in the outer tube 4, the insulating inner tube 5 is a hollow rotating body, and the conductive copper tube 6 is set in the insulating inner tube 5, the head of the conductive copper tube 6 and the head of the insulating inner tube 5 form a stepped matching structure, and the tops of the outer tube 4, the insulating inner tube 5 and the conductive copper tube 6 jointly form a power connection interface 17, The bottom of the conductive copper tube 6 is provided with a groove 16 with an internal thread on the inner wall, and the top of the cathode 7 is screwed to the groove 16. The outer tube 4, the...
Embodiment 2
[0064] Such as Figure 6 to Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that the air inlet 10 of the igniter is a chute structure, and the air inlet 10 of the igniter is in the shape of a vane. In this embodiment, the structures, connections and working principles of other parts are the same as those in Embodiment 1.
Embodiment 3
[0066] Such as Figure 9 to Figure 11 As shown, the difference between this embodiment and Embodiment 1 is that: the air inlet 10 of the igniter is composed of a plurality of meshes arranged in a rectangular array; the angle between the meshes and the horizontal plane is 0°.
[0067] In this embodiment, the structures, connections and working principles of other parts are the same as those in Embodiment 1.
