[0052] The three sets of external annular coils 6 are wound on the surface of the discharge chamber 2, including:

[0053] The coil 6-1 at the discharge chamber entrance, the coil 6-3 at the discharge chamber exit and the coil 6-2 in the middle of the discharge chamber are referred to as the three groups of external annular coils 6. The coil 6-1 at the discharge chamber entrance refers to the external coil at position 1 of the discharge chamber entrance, the coil 6-2 in the middle of the discharge chamber refers to the external coil at the middle position of the discharge chamber, and the coil 6-3 at the discharge chamber exit refers to the external coil at position 5 of the discharge chamber exit. The three groups of additional annular coils 6 are symmetrically wound along the annular direction, and the structures of the three groups of additional annular coils 6 are different, wherein the coil 6-1 at the discharge chamber entrance and the coil 6-3 at the discharge chamber exit are wound along the surface of the discharge chamber 2 in an annular direction, and the coil 6-2 in the middle of the discharge chamber is wound into a saddle-shaped coil along the surface of the discharge chamber 2; the coil 6-1 at the discharge chamber entrance, the coil 6-2 in the middle of the discharge chamber, and the coil 6-3 at the discharge chamber exit are installed at equal intervals; the axis of the coil 6-1 at the discharge chamber entrance, the axis of the coil 6-3 at the discharge chamber exit, and the axis of the coil 6-2 in the middle of the discharge chamber are consistent with the axis of the discharge chamber 2.

After a preset time, the coil 6-2 in the middle of the discharge chamber is controlled to discharge, thereby enhancing the radial magnetic field 7-1 of the plasma cluster with improved acceleration performance of the plasma cluster; the preset time is about 5 to 10 μs.

[0056] The working mode of the three groups of external annular coils 6 is pulse discharge; during discharge, the three groups of external annular coils 6 feed a constant current, the current waveform is a square wave, and the discharge pulse width is about 3 to 7 μ s; the constant current is a steady current. The embodiment of the present application realizes the enhancement of the radial magnetic field 7-1 of the plasma group by feeding a steady current into the radial induced magnetic field through the three groups of external annular coils 6.

[0060] During operation, under the joint action of the discharge chamber 2, the radio frequency antenna 4, and the solenoid electromagnet 3, the propellant discharges inside the discharge chamber 2 and forms a plasma mass 7. The plasma mass annular current 7-2 in the plasma mass 7 and the plasma mass radial magnetic field 7-1 are coupled to generate an electromagnetic Lorentz force, and the plasma mass 7 is ejected at a high speed under the acceleration of the electromagnetic force to generate thrust. The three sets of additional annular coils 6 are used to quickly discharge and generate a short-term, higher-intensity plasma mass radial magnetic field 7-1 through the control system after the plasma mass 7 is formed and before it is ejected, so as to achieve artificial enhancement of the plasma mass radial magnetic field 7-1, thereby improving the acceleration performance of the plasma mass 7.

The present application can solve the difficult problems of the existing acceleration of the plasma group 7, such as the low electromagnetic Lorentz force and the poor radial confinement performance of the plasma group 7, caused by the weak radial magnetic field 7-1 of the plasma group. The present application uses three sets of external annular coils 6 and pulses a steady current to flexibly increase the intensity of the radial magnetic field 7-1 of the plasma group, improve the plasma ionization rate, and drive the radio frequency antenna 4 to increase the annular current 7-2 of the plasma group; the project is easy to implement and easy to operate. It only requires adding a set of annular coils to the original electric propulsion prototype, and the discharge time of the three sets of external annular coils 6 is strictly controlled by the control system, which can avoid electromagnetic compatibility problems caused by the introduction of the coils.

[0097] In one embodiment, when the processor 1001 executes the control system to control the discharge of the three groups of external annular coils to enhance the radial magnetic field of the plasma mass to improve the acceleration performance of the plasma mass, the processor 1001 specifically performs the following operations:

[0098] The control system adopts a sequential discharge control method to control the coil at the entrance of the discharge chamber and the coil at the exit of the discharge chamber to discharge synchronously with the four groups of radio frequency antennas orthogonally wound on the surface of the discharge chamber. After a preset time, the coil in the middle of the discharge chamber is controlled to discharge, thereby enhancing the radial magnetic field of the plasma cluster with improved acceleration performance of the plasma cluster.

[0099] In the embodiment of the present application, the radial magnetic field enhancement method and device for improving the acceleration performance of plasma clusters are as follows: four groups of radio frequency antennas and three groups of external annular coils are wound on the surface of the discharge chamber, and multiple groups of solenoid electromagnets are arranged coaxially with the discharge chamber and arranged outside the discharge chamber and the four groups of radio frequency antennas; the three groups of external annular coils are controlled to discharge by a control system to enhance the radial magnetic field of the plasma cluster for improving the acceleration performance of the plasma cluster; the three groups of external annular coils are used to enhance the ionization of the propellant inside the discharge chamber, and the annular current of the plasma cluster for improving the acceleration performance of the plasma cluster is enhanced. The present application can solve the difficult problems of the existing plasma cluster acceleration, such as the low electromagnetic Lorentz force and poor radial confinement performance of the plasma cluster caused by the weak radial magnetic field of the plasma cluster. The present application uses three sets of external toroidal coils and pulses a steady current to flexibly increase the radial magnetic field strength of the plasma group, improve the plasma ionization rate, and increase the toroidal current of the plasma group driven by the radio frequency antenna. The project is easy to implement and easy to operate. It only requires adding a set of toroidal coils to the original electric propulsion prototype. The discharge time of the three sets of external toroidal coils is strictly controlled by the control system, which can avoid electromagnetic compatibility problems caused by the introduction of the coils.
