specific Embodiment approach 1

[0014] Specific implementation mode 1. Combination figure 1 , figure 2 , image 3 and Figure 4 Describe this embodiment, a method for controlling the plume divergence angle of a tangential magnetic field thruster described in this embodiment, the specific steps of the method are:

[0015] Step 1. Fix an annular plume control permanent magnet on the outside of the outermost permanent magnet at the outlet of the discharge channel of the tangential magnetic field thruster; The polarity of the permanent magnet is opposite;

[0016] Step 2: Ignite the cathode of the cusp magnetic field thruster, the cathode of the thruster emits electrons, and the electrons move to the inside of the discharge channel under the action of the electromagnetic field;

[0017] Step 3. Introduce xenon gas into the discharge channel of the cusp magnetic field thruster, and gradually increase the anode voltage with a step size n until the thruster ignites successfully; where n is a positive integer, ...

[0025] Specific Embodiment 2. This embodiment is a further description of a method for controlling the plume divergence angle of a tangential magnetic field thruster described in Embodiment 1. The annular plume control permanent magnet described in step 1 consists of a shaft It is composed of a permanent magnet magnetized radially and a permanent magnet magnetized radially.

[0026] An annular axial permanent magnet is placed above the permanent magnet of the tangential magnetic field thruster, and its polarity is opposite to that of the permanent magnet of the tangential magnetic field thruster. The degree of convexity of the magnetic interface after the axial permanent magnet is installed is the same as that without installation Compared with the axial permanent magnet, the outer convex degree of the magnetic interface is significantly lower, so the installation of the permanent magnet ring with opposite polarity can effectively improve the configuration of the magnetic inter...

Abstract

The invention provides a method for controlling a cusped magnetic field thruster plume divergent angle and relates to the method for controlling the plume divergent angle through cusped magnetic field thruster magnetic interface configuration to solve the problem that an existing cusped magnetic field thruster plume divergent angle is difficult to control. An annular plume control permanent magnet is fixedly arranged on the outer side of a permanent magnet which is arranged on the outmost face of a cusped magnetic field thruster channel outlet, a negative electrode of a thruster sends out electrons, xenon is filled into a discharging channel of the cusped magnetic field thruster, xenon ions are sprayed out of the discharging channel under the action of an electric field which is generated through self-consistence of the xenon ions and the electrons so that inward thrust is generated, annular plume control permanent magnets with different axial lengths and radial lengths are replaced so that the protruding extent of the magnetic interface configuration of the channel outlet can be reduced and the acceleration direction of the xenon ions can controlled, namely, the cusped magnetic field thruster plume divergent angle is controlled. The method for controlling the cusped magnetic field thruster plume divergent angle is suitable for controlling the cusped magnetic field thruster plume divergent angle.

Description

technical field [0001] The invention relates to a method for controlling the plume divergence angle by the configuration of the magnetic interface of a tangential magnetic field thruster Background technique [0002] The tangential magnetic field thruster is a new type of electric propulsion device. Its main structure is composed of a cylindrical ceramic discharge channel and an annular permanent magnet with opposite polarity. figure 1 As shown, it utilizes the electrons bound by the tangential magnetic field to ionize the inert gas working medium to form a high-speed directional plasma jet, thereby generating thrust. Compared with the traditional electric propulsion device, the tangential magnetic field thruster has become the most valuable electric propulsion device for engineering application and development due to its advantages such as wide thrust range, low working medium pollution, high efficiency, small wall erosion, and long service life. Since the plasma generated...
