With, including gesture stability, north-south position holding, Orbit Transformation, atmospheric damping compensate, survey of deep space promote mainly into etc..Especially in depth
In empty detection mission, the features such as electric propulsion technology is with its high specific impulse, long-life, propellant carrying amount can be greatlyd save, increase
Spacecraft payload ratio, has very strong advantage.
Ring cutting field ion thruster arc chamber has discharging efficiency height, the sensing of line good straightness degree, required permanent magnet magnetic by force
Spend weak advantage.Major diameter annular magnetic steel not easy processing and magnetizing, generally prepares magnet steel ring using the method for fritter magnet steel splicing,
This method exist because of magnet steel between repulsion difficulty or ease close-packed arrays, assembling is difficult.Meanwhile, the height producing during ion thruster work
Temperature, proposes high requirement to magnet steel heatproof.The present invention solves and is assembled into phase during annular magnetic steel by multiple fritter magnet steel
Mutually repel and be difficult to the problem and annular magnetic steel assembly problem on thruster of closely arranging, reduce ion thruster to magnet steel
Applied at elevated temperature requires.
Content of the invention
The technical problem to be solved is to provide a kind of ion thruster ring for the problems of the prior art
Shape magnet steel mounting structure, the present invention solves and is assembled into mutually exclusive during annular magnetic steel being difficult to closely by multiple fritter magnet steel
Arrangement installation question, reduces ion thruster by the design of magnet steel installation site and the applied at elevated temperature of magnet steel is required.
Technical problem for solving the present invention adopts the following technical scheme that：
A kind of ion thruster annular magnetic steel mounting structure, including magnet steel, pole shoe, described pole shoe and magnet steel are placed in magnet steel box,
Described alinco assembled is to the close-packed arrays that using pole shoe, the attraction of magnet steel is realized during magnet steel box with fritter magnet steel, described magnet steel box
