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.

对霍尔推力器的高功率、高比冲特性进行了实验研究。输入功率和比冲分别达到5 kW和3, 000 sec以上。霍尔推进器有望用于未来的太空探索。本文介绍了日本大坂工业大学两种霍尔推力器的最新研究进展。特别是，日本在空间推进，霍尔推力器的高功率和高比冲特性的实验室模型的SPT型THT-VI和TAL型TALT-2的测量，以获得基本的推力器性能与高放电电压和大质量流量，并了解在高功率操作下的实际问题。对于THT-VI，放电电流在恒定的质量流率下几乎是平坦的，尽管在800- 1000 V的高放电电压下不是那么好。输入功率达到5 kW以上。推力和比冲均随放电电压的增加而线性增加。比冲1500- 4000秒时，推力范围为50 - 200 mN。推力效率达到60%以上。典型的推力性能是，在输入功率为2.8kW、比冲为3200 sec时，推力为110 mN，推力效率为61%。放电电流的振荡随放电电压的升高而增大。TALT-2推力器的输入功率大于3.5kW，比冲大于2800秒。
