In January 2022, the Lanzhou Institute of Space Technology Physics achieved a major breakthrough in the high-power Hall electric propulsion technology. In the ground test, the single-channel Hall thruster (HET-450) used Xe as the working fluid to achieve a maximum power of 105kW and a maximum thrust reaches 4.6N, and the highest specific impulse with krypton as the working fluid exceeds 5100s, which indicates that in the field of high-power electric propulsion technology in my country, the performance of the 100-kilowatt Hall thruster has reached the international advanced level, and the single-channel Hall thruster is comparable to that of the United States. The technical level of the multi-channel X3 Hall thruster (maximum power 102kW, maximum thrust 5.4N).
High-power electric propulsion is the strategic direction of my country's advanced aerospace power field. Among them, high-power Hall electric propulsion has the outstanding advantages of high thrust-to-power ratio and large thrust, and is currently the international mainstream high-power electric propulsion technology route closest to space applications. After years of unremitting efforts, the team has overcome many challenges, solved more than 10 internationally recognized technical problems, and mastered a number of core technologies with independent intellectual property rights. "Overtaking" and "international leadership" will provide key technical support for the smooth implementation of my country's manned moon landing, on-orbit services and other milestone tasks in the construction of a space powerhouse.
