下一个世纪,电推进技术将作为全球空间推进领域的明星迈入其成熟阶段。在日本,业已对工程试验卫星(ETS)和通信,广播工程试验卫星(COMETS)搭载的电推进系统以及空间自由飞行器(SFU)上装备的稳态MPD推力器成功地进行了飞行验证。日本宇宙开发事业团(NASDA)计划于2002年在ETS-Ⅷ卫星上试飞改进型电推进系统(IES),并打算在数据中继试验卫星(DRTS)上采用1.8kW/250mN级别的肼直流电弧推力器。日本宇宙与航天科学研究所(ISAS)正在促进小行星采样和回收空间飞行任务(MOSES-C),该项目计划于2002年发射,然后在2006年从一个外行星星体上将一些采样样品返回到地面。在MUSES C飞行任务中,准备用小阴极微波放电离子发动机系统作为行星际航行的主推进系统。此外,还正在研究30cm直径的环形尖端氙离子推力器、20cm直径的微波放电离子推力器、以C_(60)为推进剂的离子推力器,0.3～1kW级的直流电弧加热推子器,大功率磁等离子体(MPD)推力器,霍尔推力器,以及这些推力器的等离子体羽统与航天器的相互干扰问题,这些研究工作旨在开发未来空间任务的电推进应用领域,掌握电推进的基本物理规律。
In the next century, electric propulsion technology will enter its maturity stage as a star in the field of global space advancement. In Japan, flight verification has been successfully conducted on engineering test satellites (ETSs) and communications, electric propulsion systems powered by COMETS satellites, and steady-state MPD thrusters on space-based free-maneuvers (SFU). NASDA plans to test a modified electric propulsion system (IES) on ETS-VIII satellite in 2002 and intends to adopt a hydrazine DC arc of 1.8kW / 250mN on data relay test satellite (DRTS) Thrust. The Japan Institute of Space and Astronautics (ISAS) is promoting the Spaceborne Mission for Asteroid Sampling and Recovery (MOSES-C), which is scheduled to launch in 2002 and return some of the samples from an asteroid in 2006 ground. In the MUSES C mission, a small cathode microwave discharge ion engine system is being prepared as the main propulsion system for interplanetary navigation. In addition, 30 cm diameter circular tip xenon ion thruster, 20 cm diameter microwave discharge ion thruster, C_ (60) propellant ion thruster, 0.3 ~ 1 kW DC arc heat spreader, large Power magnetic plasma (MPD) thrusters, Hall thrusters, and plasma plutonium and spacecraft for these thrusters, are all designed to develop the field of electrical propulsion applications for future space missions, mastering electrical propulsion The basic laws of physics.
