Embodiment 1
[0033] refer to figure 1 As shown, an electrode for an aero-engine includes a temperature-resistant and conductive electrode inner core 36 and a temperature-resistant and anti-corrosion electrode outer wall 37, and the electrode outer wall 37 is wrapped on the exposed surface of the electrode inner core 36, and a plurality of electrodes Installed in the combustion chamber B of the engine, and a plurality of electrodes can generate an electric field in the combustion chamber B. The inner core 36 of the electrode is made of platinum, rhodium, tungsten or its alloy materials, so as to meet the requirements of electrical conductivity and heat resistance when working in the combustion chamber, and the outer wall of the electrode is made of ceramic materials such as alumina and zirconia or other insulating, The coating of dense material ensures that the electrode inner core 36 does not directly contact with gas or air during the working process, so as to prevent ablation or corrosio...
Embodiment 2
[0038] In order to realize the second purpose of the present disclosure, the technical solution adopted in the present disclosure is as follows:
[0039] refer to figure 2Shown, a kind of aeroengine comprises engine body A, and engine body A can comprise air inlet 1, fuel inlet pipe 2, engine casing 3, nozzle assembly 25, outlet 11, outer flame tube wall 22, inner flame tube wall 23 , there is the combustion chamber B between the outer flame tube wall 22 and the inner flame tube wall 23; The wall hole 16 of the ring tube enters the combustion chamber B, the fuel inlet pipe 2 feeds fuel into the nozzle assembly 25, the fuel is injected into the combustion chamber B through the nozzle assembly 25, and the fuel and air are ejected from the outlet 11 after being burned in the combustion chamber B. The cross-section of the combustion chamber B of the engine can be a cylindrical combustion chamber cross-section or a circular ring, etc. The combustion chamber has a head area B1, a ...
Embodiment 3
[0062] to combine figure 1 As shown, the electrodes C include linear axial electrodes C1, and a plurality of axial electrodes C1 are arranged parallel to the axial direction of the combustion chamber. A plurality of axial electrodes C1 can be arranged in multiple concentric circular arrays, or in a rectangular array, or in an interlaced rectangular array. The number of axial electrodes C1 can be controlled according to the electric field Precision to set the degree of density. Applying different voltages at any distance and between any two axial electrodes C1 can generate electric fields of different strengths according to this formula. This creates an electric field between the two axial electrodes C1 in the combustion zone and in the mixing zone.
[0063] The axial electrode C1 includes the combustion zone axial electrode 9 and the mixing zone axial electrode 10, the combustion zone axial electrode 9 penetrates between the head end wall 39 and the combustion zone electrode...
