Embodiment 1
[0021] Example 1 is as figure 1 As shown, an electronically controlled vector thrust electric thruster uses an insulating nylon material to make a casing (1), a required ion source (2) is installed inside the casing (1), and an induction electrode (6) passes through the installation groove (3) Insert into the casing (1); the induction electrode (6) and the ion source (2) together form the potential difference required to generate charged particles; the two pairs of deflection electrodes (4, 5) are installed on the machine through the installation slot (3) In the four directions of the box (1), the mounting groove (3) and each mounting piece are tightly fitted, and a small amount of glue is added to the gap to ensure the reliability in work.
[0022] When the thrust direction needs to be deflected in the X direction, adjust the voltage of the two X-direction deflection electrodes (4). For example, if the ion source produces positively charged particles, apply a lower positive p...

The invention provides an electronically controlled vector thrust electric thruster, which includes a casing, an ion source, a mounting slot, an X-direction deflection electrode, a Y-direction deflection electrode, and an induction electrode; the casing includes a concave cavity and four columns, There are installation grooves on the column and the wall of the cavity; the ion source is installed in the cavity of the casing, and the ion source can be a liquid ion source, a liquid metal ion source, a gas ion source, a solid ion source; the X direction The deflection electrode consists of two electrodes to form a pair, according to the need to continue to add more pairs of X-direction deflection electrodes in the axial direction; the Y-direction deflection electrode consists of two electrodes to form a pair, and can continue to add more pairs in the axial direction as required For Y-direction deflection electrodes; the present invention can realize vector thrust output by simultaneously adjusting the potentials of two pairs of deflection electrodes, thereby completing more complex attitude control tasks, or reducing the number of propellers required; the present invention can also realize plume divergence Angle control, thereby reducing the non-axial thrust loss of the propeller and improving the efficiency of the propeller.
Description
technical field [0001] The invention belongs to the field of aerospace propulsion, and relates to an electronically controlled vector thrust electric thruster. Background technique [0002] An electric thruster is a type of propulsion device that generates charged particles from an ion source and generates thrust by accelerating the charged particles. Electric thrusters are widely used in spacecraft orbital maneuvering, attitude control, etc. At present, the ion sources commonly used in electric propulsion devices include ionic liquid ion sources, liquid metal ion sources, and gas ion sources. Most of the current electric propulsion devices can only generate thrust in one direction and do not have vector thrust capability. In order to realize the three-axis maneuver of the spacecraft, multiple pairs of thrusters need to be installed; the launch plume of the electric thruster usually has a large divergence angle , will cause non-axial thrust loss. In order to improve the a...
