| Outline of Final Research Achievements |
The objective of this study is to investigate primary subjects for development and improvement of thin, small or large DC plasmajet-array. Firstly, micro-fabrication and demonstration of micro-plasmajet-array were conducted. It was shown that multi-nozzle configuration of thin nozzle elements was appropriate for large thrusters rather than small thrusters, and that thrust performance was higher than single nozzles with the same sizes. Secondly, development of a novel laser-thermal micro-plasmajet employing a laser-diode coupled fiber-tip heat source was conducted for a potential candidate of innovative micro-nozzle elements. In addition, to employ and enhance chemical energy required for low-power plasma sources, development of novel, safe, non-toxic liquid propellant was conducted. Some potential liquids were extracted.
