京都大学大学院 工学研究科 航空宇宙工学専攻
超小型人工衛星の軌道・姿勢制御を用途としたマイクロ波励起マイクロプラズマスラスタを対象に、数値計算による性能見積もりを行った。解析にはマイクロプラズマ源とマイクロノズル流れを分けて行い、前者には体積平均モデルとマクスウェル方程式を利用し、後者には2温度モデルに基づくナビエ・ストークス方程式を利用した。分散関係式との比較により表面波の伝播を確認し、また、境界層が支配的なことから、ノズルの全長を短くすることが性能向上に望ましいと分かった。

<p>In recent years, many nano/microsatellites have been launched in space for various applications in near-earth orbit, and they are now used even for deep-space exploration. The situation naturally requires a micropropulsion system or microthruster. It is expected that electric propulsion will play an important role in achieving the required velocity increment (⊿<i>v</i>) because nano/microsatellites have strict constraints on space and weight. In this paper, we focus on two types of microthrusters, an ion engine and an electrospray thruster, which obtain thrust by electrostatically accelerating ions, and describe their characteristics, current results, and some issues. We also introduce electron sources, which do not directly contribute to thrust but are essential components.</p><p>In recent years, many nano/microsatellites have been launched in space for various applications in near-earth orbit, and they are now used even for deep-space exploration.

Current status of a magnetic nozzle RF plasma thruster

Language:Japanese Publishing type:Article, review, commentary, editorial, etc. (scientific journal) Publisher:Space Solar Power Systems Society Joint Work
<p> The magnetic nozzle RF plasma thruster simply consists of a radiofrequency (RF) discharge and a magnetic nozzle. The high density plasma produced by inductively-coupled and/or helicon-wave-coupled discharge is transported along the axial magnetic field lines to the open source exit; the spontaneous plasma acceleration and momentum conversion processes seem to contribute to enhance the thrust generation. Current status of the studies on the fundamental physics and the performance improvement will be shown here.</p><p> The magnetic nozzle RF plasma thruster simply consists of a radiofrequency (RF) discharge and a magnetic nozzle.

<p> A panel discussion was held to discuss the technical challenges in orbital transfer vehicle (OTV) development using electric propulsion. Electric propulsion is advantageous in the transportation of SSPS if the solar array panel in the payload can be used in the OTV. Argon is the candidate for the propellant, and the technical issues for the development of high-power argon-propellant thruster are discussed. The collaboration with the ground launch vehicle is indispensable to attain the SSPS, in addition to the cross-field collaboration for the optimization of the OTV. The necessity of technology demonstration missions and technical roadmap is reconfirmed to promote the collaboration among the researchers.</p><p> A panel discussion was held to discuss the technical challenges in orbital transfer vehicle (OTV) development using electric propulsion.
