Embodiment Construction

[0011] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0012] The invention provides an ion and Hall hybrid electric thruster, such as figure 1 As shown, it mainly includes ion inner ring, Hall outer ring, cathode and magnetic shielding structure. Among them, the ion inner ring adopts a DC ion thruster structure; the Hall outer ring is designed with reference to the Hall thruster structure and adopts a steady-state plasma structure; the ion inner ring and the Hall outer ring are arranged in concentric circles, and the Hall outer ring is nested On the outside of the ion inner ring; between the ion inner ring and the Hall outer ring, there is an annular magnetic shielding structure made of permanent magnet material; the cathode is a hollow cathode structure, located outside the Hall outer ring.

[0013] During the working process of the ion and Hall hybrid electric thruster, the magnetic shield can prevent the ...

Abstract

The invention discloses an ion and Hall hybrid type electric thruster. By means of the ion and Hall hybrid type electric thruster, an ion thruster and a Hall thruster can be effectively combined, the integral design is formed, and the thruster can fully inherit the advantages of the ion thruster and the advantages of the Hall thruster. The ion and Hall hybrid type electric thruster comprises an inner ion ring, an outer Hall ring, a cathode and a magnetic shielding structure, wherein a direct current ion thruster structure is adopted in the inner ion ring; a steady state plasma Hall thruster structure is adopted in the outer Hall ring; the inner ion ring and the outer Hall ring are concentrically arranged, and the outer Hall ring is embedded in the outer side of the inner ion ring; the annular magnetic shielding structure made of permanent magnet materials is arranged between the inner ion ring and the outer Hall ring. The cathode is of a hollow cathode structure and is located on the outer side of the outer Hall ring.

Description

technical field [0001] The invention relates to the fields of aerospace technology and low-temperature plasma technology, in particular to an ion and Hall hybrid electric thruster. Background technique [0002] Electric thrusters have the advantages of high specific impulse, high reliability, and long life. They are an important way to increase satellite payloads and have important aerospace application values. There are two types of electric propulsion currently used in space: ion and Hall. Among them, the ion thruster has the characteristics of high specific impulse, long life, and relatively low power-to-thrust ratio, while the Hall type thruster has the characteristics of high power-to-thrust ratio, high reliability, and relatively low specific impulse. The current thruster selection is to choose ion electric thrusters or Hall thrusters according to the needs of space propulsion tasks. The size and weight are not conducive to the multi-tasking of satellite space. Con...
