Thanks to CTOnews.com netizen grass Luo Yuzi for the clue delivery! CTOnews.com January 18 news, According to Lanzhou Institute of Space Technology Physics released, In 2023 at the beginning of the year, By the institute electric propulsion business department and secondary power business department jointly developed 100kW Hall thruster and high-power PPU prototype for the first time successfully ignited joint test.

In 2021, the 100kW high-power Hall electric propulsion system was selected as the first batch of technical directions and key products of the Institute. Since then, the Institute has successively broken through key technologies such as 100-ampere high-current cathode technology, discharge chamber magnetic field "magnetic shielding" technology, space power application technology based on new power devices, ultra-high-power high-efficiency conversion technology, wide-range power and voltage regulation, etc., and completed the first joint test ignition of 100-kilowatt Hall thruster and high-power PPU prototype. Under the stable output condition of 50kW power of a single PPU prototype, the thrust reached 2.1N. The measured index of specific impulse 2980s has reached the leading level in China, realizing the technical breakthrough of the high-power Hall electric propulsion system of our institute and achieving important phased achievements.

CTOnews.com learned that the high-power Hall electric propulsion system has technical characteristics such as large thrust ratio and high power density, and has wide application prospects in space missions such as large-scale orbital transfer, interplanetary cargo transportation and deep space exploration.
