| 摘 要： | High power Hall electric propulsion technology is a very competitive electric propulsion technology for future large space missions such as large GEO satellites, manned space programs, deep space explorations, cargo ships, space tugs. Based on the experience of more than 20 years in research and development of Hall electric propulsion, the Shanghai Institute of Space Propulsion(SISP) has developed 3 high power Hall thrusters, i.e., the 10 kW class HET-500, 20 kW class HET-1000, and 50 kW class HET-3000. This paper presents the development status of the high power( ≥ 10 kW) Hall electric propulsion at SISP, including tests of 3 high power Hall thrusters in the power range from 10 kW to 50 kW, the qualification of a single string of a 10 kW Hall electric propulsion system, and the study of a cluster of two 1.35 kW HET-80 Hall thrusters to understand the technical issues related to multi-thruster high power electric propulsion systems.
