项目摘要

High power and high specific impulse characteristics of Hall thrusters were experimentally studied. Input power and specific impulse reached above5kW and 3,000sec, respectively. Hall thrusters are expected for future space exploration. In this study, we introduce the recent research and development of two kinds of Hall thruster at Osaka Institute of Technology, Japan. Specially, for Japanese in-space propulsion, high-power and high-specific-impulse characteristics of Hall thruster were measured with both the laboratory-model SPT-type THT-VI and TAL-type TALT-2 in order to obtain basic thruster performances with high discharge voltage and large mass flow rate and to understand practical problems under high power operations. With THT-VI the discharge current was almost flat with a constant mass flow rate although not so good with high discharge voltages of 800-1000V. The input power reached above 5kW. Both the thrust and the specific impulse linearly increase with discharge voltage. The thrust ranges from 50 to200mN at specific impulse of 1500-4000sec. The thrust efficiency reaches above 60%. Typical thrust performance is a thrust of 110mN and a thrust efficiency of 61% at a specific impulse of 3200sec with an input power of 2.8kW. The discharge current oscillation also increased with raising discharge voltage. As for TALT-2 thruster, the input power and the specific impulse are above 3.5kW and, 2800sec, respectively.

对霍尔推进器的高功率、高比冲特性进行了实验研究。输入功率达到5kW以上，比冲达到3000秒以上。霍尔推进器有望用于未来的太空探索。在这项研究中，我们介绍了日本大阪工业大学两种霍尔推进器的最新研发情况。为了获得高放电电压、大流量的霍尔推进器的基本性能，了解高功率工作条件下的实际问题，特别是针对日本空间推进，用实验室SPT型THT-VI和TAL型TALT-2型两种仪器对霍尔推进器的高功率、高比冲特性进行了测试。对于THT-VI，在恒定的质量流量下，放电电流几乎是平坦的，但在800-1000V的高放电电压下则不是很好。输入功率达到5kW以上。推力和比冲均随放电电压线性增加。推力范围为50~200mN，比冲1500~4000秒。推力效率达到60%以上。典型的推力性能为110MN，比冲为3200秒，输入功率为2.8kW，推力效率为61%。放电电流的振荡也随着放电电压的升高而增大。对于TALT-2推进器，输入功率大于3.5kW，比冲大于2800秒。
