Example Embodiment

[0033] Example one:

[0034] Such as figure 1 As shown, this embodiment provides a micro-cathode arc thruster, which includes an insulating base 1, an anode 2, a sheathed cathode 3 sheathed outside the anode 2, and a shell 4 whose bottom is butted with one end of the insulating base 1. The anode 2 and the sheath An insulator layer 5 is arranged between the layer cathodes 3; the other end of the insulating base 1 is provided with an anode terminal 6 and a cathode terminal 7 extending outward and spaced apart. The anode 2, the sheathed cathode 3 and the insulator layer 5 are all covered by the housing 4 Inverted.

[0035] In this embodiment, such as figure 1 As shown, the center of the insulating base 1 is provided with a second-stage installation hole 8, and the anode terminal 6 is located at the small hole end of the second-stage installation hole 8, and is coaxially connected with the second-stage installation hole 6.

[0036] In this embodiment, such as figure 1 As shown, the anod...

Abstract

The invention discloses a novel micro-cathode arc propeller which comprises an insulating base, an anode, a sleeve layer cathode sleeved outside the anode and a shell. The bottom of the shell is in butt connection with one end of the insulating base. An insulator layer is arranged between the anode and the sleeve layer cathode, the other end of the insulating base is provided with an anode wiringpost and a cathode wiring post which are extended outwards and distributed in a spaced mode, and the anode, the sleeve layer cathode and the insulator layer are all located in the shell. Since the anode wiring post and the cathode wiring post on the insulating base, and the insulator body is added, the anode and the cathode have better insulativity, the discharge problem is effectively avoided, the problems of mechanism melting partially caused by electric leakage and materials are solved, the assembly difficulty and the assembly time can be greatly reduced, the structural stability is increased, and the practicability is strong.

Description

technical field [0001] The invention relates to the technical field of satellite electric propulsion, in particular to a micro-cathode arc thruster. Background technique [0002] The microcathode arc thruster is an emerging electromagnetic propulsion method, which is expected to be used for orbit maintenance of various microsatellites. It has the advantages of high specific impulse, simple structure, low power, and does not require an air supply system. [0003] Micro-cathode arc thrusters include three types of structure: coaxial type, ring type and hybrid type, but no matter which structure is used, they all have the same principle: [0004] 1). They all rely on short-time high-voltage pulse discharge between the cathode and anode to ionize the conductive carbon paint to generate plasma to form a path, so as to achieve the purpose of ignition; [0005] 2). They all rely on the deflection of the magnetic field to make the particles generate an outward jet to generate thru...
