Background technique
Satellite develops towards low cost, distributed direction in recent years.Micro-nano satellite have it is at low cost, the lead time is short,
The advantages that extended capability is strong, radiation pattern is flexible, micro-nano satellite all have civil and military important application prospect and strategy
Meaning.Microsatellite, the fast-developing of micro-nano satellite propose very high requirement for propulsion.Vacuum Arc thruster (VAT) because
Its quality is small, than leaping high, the advantages such as structure is simple and become the ideal electric propulsion type of micro-nano satellite.Small propulsion can mainly expire
The propulsion demand of sufficient micro-nano satellite specifically includes that (1) damping compensation, track lifting, position is kept and motor-driven, gesture stability, hair
Penetrate error correction etc.；(2) thrust can wide scope quickly adjust, such as without towing control, precise formation flight.Vacuum Arc thruster
Performance and the service life be of great significance for meeting the propulsion demand of micro-nano satellite.Current single cathode and single anode are coaxially true
Empty arc thruster is small by cathode burning corrosion area, causes the service life of thruster shorter, and reliability is lower, while plume is due to space electricity
Lotus effect and the angle of divergence is larger, influence the performance of thruster.Design has long-life, highly reliable, high performance Vacuum Arc thrust
Device has the important meaning.It is expected to increase considerably the life and reliability of Vacuum Arc thruster by increasing number of poles, simultaneously
The performance of thruster is improved, and is had to high-power scalability.
Summary of the invention
The present invention proposes a kind of tricyclic Vacuum Arc thruster, facilitates the raising in thruster performance and service life.
The technical scheme adopted by the invention is as follows:
A kind of tricyclic Vacuum Arc thruster, the thruster include the cathode for being placed in center, which successively sets with one heart
Set insulator II, common anode, insulator I and outer ring cathode；The cathode, insulator II, common anode, insulator I and outer
Ring cathode is sequentially arranged at the cathode mounting groove of mounting seat, insulator II mounting base, common anode mounting groove, insulator I peace
It fills in seat and outer ring cathode mounting groove；The outer end face of the mounting seat sets gradually cathode terminal, common from center outward
Anode terminal and outer ring cathode terminal；The cathode terminal and outer ring cathode terminal are connected to the cathode of power supply, jointly
Anode terminal is connected to the anode of power supply；Metal is coated on the end face that insulator I and insulator II is in mounting seat to lead
Electrolemma.
The cathode is column construction.
The present invention is based on the coaxial type Vacuum Arc thruster technology of current relative maturity, a kind of the general of tricyclic VAT is proposed
It reads, the intension of this concept is to be improved to single cathode, single anode construction altogether on the basis of current mature coaxial type VAT is designed
The twin cathode structure of anode.When thruster works, the Voltage Peak that power supply processing unit generates punctures between two groups of anode and cathodes simultaneously
Conductive film on insulator induces the main discharge between two groups of anode and cathodes.Two cathode end faces generate cathode protection, cathode simultaneously
The electronics of transmitting causes the ionization of the metallic atom of transmitting to generate plasma, and plasma is in pneumatic and electronics-ionic friction
Etc. mechanism accelerate lower to generate thrust.The invention has the advantages that (1) increased outer ring cathode increases the uniform of cathode burning corrosion
Property, be conducive to the service life for increasing thruster；(2) increased outer ring cathode reduces plume ion current density, can reduce space
Charge effect reduces the plume angle of divergence, and increased thrust improves the efficiency of thruster, and can reduce plume metal ion pair
The pollution on spacecraft surface；(3) it can further be developed to more multiring structure based on structure of the invention, thruster can be expanded
Power, expand the application range of thruster.
