“…Because DC arcjet thrusters aerodynamically accelerate the propellant through a nozzle, propellants with small molecular weight are favorable to attain high performance. Hydrogen arcjets can achieve 1,000 to 2,000 s Isp with 30 to 50 % of thrust efficiency [8][9][10] . As for MPD thrusters, in addition to the aerodynamic acceleration, critical velocity reaches the highest by applying hydrogen, and it was reported that 10,000 s Isp can be obtained 11 .…”

High power electric propulsion system is strongly required for future orbital space transportation. MPD (Magneto-Plasma-Dynamic) thrusters and DC (Direct Current) arcjets with hydrogen as a propellant are promising candidates for the missions because of their high performance and adaptability to high power operation. However, to use hydrogen for long term orbital missions, its storage in orbit is crucial issue to be considered. Firstly, we proposed a hydrogen storage and feed system for electric thrusters by applying our technologies derived from the liquid hydrogen launch vehicles. Secondly, we present R&D activities of hydrogen MPD thruster and DC arcjet, especially focusing on the improvement of their performance and durability. Then, development strategy of hydrogen electric thrusters is also discussed. Finally, advantages of hydrogen electric thruster were shown compared with conventional xenon thrusters through mission analyses of lunar orbit insertion and GTO-GEO transportation.
