Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)), Sagamihara, Kanagawa Japan The direct-current (DC) arcjet thruster is one of electric propulsion for satellite attitude control and orbital transfer. Hydrazine is mainly used as the propellant because it can be used together with chemical thrusters. In this study, performance characteristics of a low-power (0.1-2.0 kW) anode-radiation-cooled arcjet thruster were measured using special gases of carbon dioxide, methane, ammonia and water as original materials in planets and satellites in the Solar System; that is, propellant can be supplied just on the planets and satellites of Moon, Mars and Jupiter Moons, although light gases of hydrazine and hydrogen are normally used with higher performance; argon and nitrogen are also used in basic experiments. Because the performances with carbon dioxide and methane were lower than that with the light gas of ammonia, the structure and operational condition should be examined to design a thruster suitable with acceptable performance for transportation in the Solar System. As for water propellant, steady-state operation was achieved with stable supply of vapor using a metal glow-plug heater or a new water-vaporing system, which was developed with a long, narrow passage and a large sheet-type heater. 著者人数: 13名 資料番号: SA6000184067 STEP-2022-015 |
