Abstract

The invention discloses a Hall effect ringlike ion thruster and belongs to the technical field of ion thrusters. The ringlike ion thruster comprises a bottom positive pole, a ringlike grid electrode,ringlike permanent magnets, insulating sleeves, a working medium distributor set, a bias discharging negative pole and a neutralizer. Working medium gas enters a discharging chamber through bottom working medium distributors. Nozzles of the working medium distributors are oriented along the wall face so that the gas can be more uniform in a cavity. An axial electric field is formed among the positive pole, the negative pole and the grid electrode. A radial magnetic field is formed by the inner ringlike permanent magnet and the outer ringlike permanent magnet, and an E*B orthogonal field is formed by the radial magnetic field and the axial electric field. Electrons sprayed out of the negative pole are subjected to Hall drift under the effect of the orthogonal field, and the working medium gas is ionized to generate plasmas. Then, the plasmas are extracted and accelerated by the ringlike grid electrode and neutralized by electrons emitted by the neutralizer to generate thrust. The ionization rate and input power of the thrust generated by the Hall effect ringlike ion thruster are far higher than those of a traditional ion thruster, and performance of the ion thruster can be remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of ion thrusters, and more specifically relates to a Hall effect ring type ion thruster. Background technique [0002] The working process of the ion thruster is roughly divided into three stages: 1) The propellant is ionized in the discharge chamber to generate ions; 2) The ions are accelerated by the grid system to form a beam; 3) The beam is neutralized by the neutralizer to form a plume flow. Among them, the stage where ions are accelerated by the grid system is the main stage for obtaining thrust and output power. This makes the thrust and power level of the ion thruster closely related to the size of the grid, and increasing the size of the grid is the key to greatly improving the thrust and power level of the ion thruster. The discharge chamber of the ring-type ion thruster is composed of two anode sleeves, and the overall shape is ring-shaped. However, since the cathode is biased to one side of the...
