[0047] The following will be combined with the Figure 1 and attached Figure 2 , a radial magnetic field enhancement method for improving the acceleration performance of plasma clusters provided in an embodiment of the present application is introduced in detail.

[0048] See Figure 1 and2 The method of the embodiment of the present application may include the following steps:

[0049] like Figure 2 As shown, the embodiment of the present application provides a radial magnetic field enhancement method for improving the acceleration performance of a plasmoid, comprising a discharge chamber 2 for propellant gas discharge, four sets of radio frequency antennas 4 orthogonally wound on the surface of the discharge chamber 2, multiple sets of solenoid electromagnets 3 coaxial with the discharge chamber 2 and uniformly distributed outside the discharge chamber 2 and the radio frequency antennas 4, and three sets of external toroidal coils 6 wound on the surface of the discharge chamber 2. The four sets of orthogonally wound radio frequency antennas 4 cover the entire surface of the discharge chamber 2. The magnetic field strength provided by the solenoid electromagnets 3 gradually weakens along the axial direction. The three sets of external toroidal coils 6 are respectively arranged at the discharge chamber entrance position 1, the discharge chamber middle position, and the discharge chamber exit position 5. This method can solve difficult problems such as weak radial magnetic field 7-1 of the plasmoid, small plasma electron current, and poor confinement performance of the plasmoid during electromagnetic acceleration of the plasmoid 7. It provides a feasible technical approach for the development of high-performance electromagnetic acceleration space electric propulsion products for plasmoid 7, and helps promote the rapid development of advanced electromagnetic propulsion power computing in space.

[0050] S100, four groups of radio frequency antennas 4 and three groups of external toroidal coils 6 are wound on the surface of the discharge chamber 2, and multiple groups of solenoid electromagnets 3 are set coaxially with the discharge chamber 2 and arranged outside the discharge chamber 2 and the four groups of radio frequency antennas 4; the material of the discharge chamber 2 can be alumina ceramic.

[0051] The three groups of external annular coils 6 are radially located between the radio frequency antenna 4 and the solenoid electromagnet 3, and are insulated from the radio frequency antenna 4 and the solenoid electromagnet 3. The three groups of external annular coils 6 are axially arranged in the middle of the solenoid electromagnet 3.

[0052] The three sets of external toroidal 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. Three sets of additional annular coils 6 are wound symmetrically along the annular direction. The structures of the three sets of additional annular coils 6 are different. The discharge chamber entrance coil 6-1 and the discharge chamber exit coil 6-3 are wound annularly along the surface of the discharge chamber 2, while the discharge chamber middle coil 6-2 is wound as a saddle coil along the surface of the discharge chamber 2. The discharge chamber entrance coil 6-1, the discharge chamber middle coil 6-2, and the discharge chamber exit coil 6-3 are installed at equal intervals. The axis of the discharge chamber entrance coil 6-1, the axis of the discharge chamber exit coil 6-3, and the axis of the discharge chamber middle coil 6-2 coincide with the axis of the discharge chamber 2. The three sets of additional annular coils 6 can be flexibly selected in actual application. One set can be used alone, or two or three sets can be used in combination.

[0054] S200, controlling the discharge of the three groups of external annular coils 6 by a control system to enhance the radial magnetic field 7-1 of the plasma cluster to improve the acceleration performance of the plasma cluster, including:

[0055] The control system uses a sequential discharge control method to control the coil 6-1 at the discharge chamber entrance and the coil 6-3 at the discharge chamber exit to discharge synchronously with the four groups of radio frequency antennas 4 orthogonally wound on the surface 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 approximately 5 to 10 μs.

[0056] The three sets of external toroidal coils 6 operate in a pulsed discharge mode. During discharge, they feed a constant current with a square wave waveform and a discharge pulse width of approximately 3 to 7 μs. This constant current is also known as a steady current. In this embodiment, the three sets of external toroidal coils 6 feed a steady current into the radial induced magnetic field, thereby enhancing the radial magnetic field 7-1 of the plasmoid.

[0057] The three groups of additional annular coils 6 are respectively wound with 2 turns or 4 turns, and the number of turns should not be too many to avoid generating adverse high-order harmonic components and affecting the discharge effect.

[0058] S300, enhancing the ionization of the propellant inside the discharge chamber 2 by the three groups of external toroidal coils 6, and enhancing the plasma cluster toroidal current 7-2 for improving the acceleration performance of the plasma cluster.

[0059] In the embodiment of the present application, the three sets of additional toroidal coils 6 can be used to enhance the ionization of the propellant gas, thereby increasing the density of the discharge plasma, and further enhancing the plasmoid toroidal current 7-2 driven by the radio frequency antenna 4, indirectly improving the electromagnetic acceleration performance of the plasmoid 7. The plasmoid toroidal current 7-2 is also called the toroidal plasma electron current.

[0060] During operation, the propellant discharges within the discharge chamber 2, under the combined action of the radio frequency antenna 4, and the solenoid electromagnet 3, forming a plasmoid 7. The coupling of the plasmoid ring current 7-2 and the plasmoid radial magnetic field 7-1 within the plasmoid 7 generates an electromagnetic Lorentz force, accelerating the plasmoid 7 at high speed, generating thrust. After the formation of the plasmoid 7 and before its ejection, the three sets of external toroidal coils 6 rapidly discharge through the control system, generating a brief, higher-intensity plasmoid radial magnetic field 7-1. This artificially enhances the plasmoid radial magnetic field 7-1, thereby improving the acceleration performance of the plasmoid 7. Figure 2 The plasmoid 7 includes the plasmoid and its acceleration mechanism.

[0061] Figure 2 In the equation, Br represents the radial magnetic field of the plasma mass 7-1, J θ represents the density of the plasma cluster circular current 7-2, F Z represents the electromagnetic Lorentz force, which is also called the axial Lorentz force.

[0062] In an embodiment of the present application, the radial magnetic field enhancement method for improving the acceleration performance of the plasma mass comprises: winding four groups of radio frequency antennas 4 and three groups of external toroidal coils 6 on the surface of the discharge chamber 2; setting multiple groups of solenoid electromagnets 3 coaxially with the discharge chamber 2 and arranged outside the discharge chamber 2 and the four groups of radio frequency antennas 4; controlling the discharge of the three groups of external toroidal coils 6 by a control system to enhance the radial magnetic field 7-1 of the plasma mass for improving the acceleration performance of the plasma mass; and enhancing the ionization of the propellant inside the discharge chamber 2 by the three groups of external toroidal coils 6 to enhance the toroidal current 7-2 of the plasma mass for improving the acceleration performance of the plasma mass. The present application can solve the difficult problem of the existing acceleration of the plasma mass 7, such as the low electromagnetic Lorentz force and poor radial confinement performance of the plasma mass 7, caused by the weak radial magnetic field 7-1 of the plasma mass. 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 increase the annular current 7-2 of the plasma group driven by the radio frequency antenna 4. The project is easy to implement and simple to operate. It only requires adding a set of annular coils to the original electric propulsion prototype. 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.

Four sets of radio frequency antennas and three sets of external toroidal coils are wound on the surface of a discharge chamber, and multiple sets of solenoid electromagnets are arranged coaxially with the discharge chamber and are all arranged outside the discharge chamber and the four sets of radio frequency antennas. The discharge of the three sets of external toroidal coils is controlled by a control system to enhance the radial magnetic field of the plasma clump, which improves the acceleration performance of the plasma clump. The ionization of the propellant inside the discharge chamber is enhanced by the three sets of external toroidal coils, thereby enhancing the toroidal current of the plasma clump, which improves the acceleration performance of the plasma clump. This application can solve the difficult problems of existing plasma clump acceleration, such as low electromagnetic Lorentz force and poor radial confinement performance of the plasma clump, caused by the weak radial magnetic field of the plasma clump. This application uses three sets of external toroidal coils and pulses of steady current to flexibly increase the radial magnetic field strength of the plasma cluster, improve the plasma ionization rate, and increase the toroidal current of the plasma cluster driven by the radio frequency antenna. The project is easy to implement and simple 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.
