Development and Qualification of a 6-kW-class Hall Thruster Subsystem for ETS-9

抄録

Hall thruster is considered the key propulsion technology for a variety of spacecraft including Earth-orbiting satellites, space transportation systems, and space exploration. To acquire medium-power Hall thruster technology, a 6-kW-class Hall thruster system is under development at Japan Aerospace Exploration Agency (JAXA), which is the first Japanese Hall thruster to be tested onboard the Engineering Test Satellite-9 (ETS-9). Onboard ETS-9, a limited flight experiment of the Japanese Hall thruster subsystem will be conducted along with four main flight-proven foreign Hall thrusters as the bus system. Prototype model thrusters as well as an engineering model power processing unit are devoted to qualification tests. The qualification tests are in progress including an endurance test and system compatibility tests. In 2024, an end-to-end verification of the flight model thruster subsystem with the whole satellite system is planned for preparing the flight that is currently scheduled in FY2025.
