TL;DR: In this paper, a double-layer pore plate type gas distributor is presented, which consists of a gas guiding column, a distributor base, a first-layer plate, a second-layer pipe, an outer baffle, an inner baffle and a fixing column.

TL;DR: In this paper, an anode magnetic screen integrated structure for a Hall thruster is presented, where holes are evenly formed in the outer circle of the anode, with the largest maximum of anode having the gas homogenization effect, and the magnetically soft alloy material is adopted to achieve the magnetic conductive function, the magnet exciting coil manner is adopted in the magnetic source, the permanent magnet manner was adopted, and therefore building of an insulation acceleration channel of the Hall thrusters is achieved.

TL;DR: In this article, a hydrazine arc thruster ignition system for inhibiting large pressure fluctuation was proposed, which consisted of a diaphragm storage tank, a propellant filter, a fuel gas generator, and an arc thrusters.

TL;DR: In this article, a Hall thruster discharge channel optimized combined channel structure is presented, which consists of three parts of the ceramic base, the inner ceramic cylinder and the outer ceramic cylinder; insertion matching parts for guaranteeing guidance and positioning are adopted between the inner and outer ceramic cylinders and the base.
