In this study, the MPD thruster doesn't have the coil for external magnetic field application but permanent magnet, Samarium cobalt. So, if magnetic Curie temperature is taken into consideration, the radiation-cooled thruster without cooling water can be designed. The manned Mars explorations which are a final objective of this study are missions for which a high specific impulse is needed. Using hydrogen, we could obtain a result of thrust 41.9 mN, specific impulse 2870 s, and thrust efficiency 12.5 %. We will perform performance improvement and heat analysis for development of a radiation-cooled thruster. And, to decrease cathode damage, we designed multi-hollow cathode. Using it, a new water-cooled thruster with changing anode geometry, distance between electrodes and magnet field strength was made., 形態: カラー図版あり, 形態: PDF, Physical characteristics: Original contains color illustrations, Physical characteristics: PDF, 資料番号: AA0061856086, レポート番号: STEP-2012-003},
