  • Development of a Miniature Electrothermal Thruster Using Microwave-Excited Microplasmas for Ultra Small Satellites(マイクロ波励起マイクロプラズマを用いた超小型人工衛星のための電熱加速型推進機の研究開発)

     View Summary

    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、数値計算と実験の双方を用いて解析した結果についてまとめた論文である。これら統合解析により、壁面の影響が極めて大きいため、圧力推力の寄与が無視できないこと、ノズル壁面は断熱壁条件より等温壁条件に近いことが分かった。プラズマ点火により推力1.4 mN、比推力79 sが得られ、コールドガスと比べて、超小型衛星(10 kg)の推進剤質量を3割以上削減可能な性能が得られた。

  • Current status of a magnetic nozzle RF plasma thruster

    TAKAHASHI Kazunori, CHARLES Christine, BOSWELL Rod, TAKAO Yoshinori, ANDO Akira

    Space Solar Power Systems ( Space Solar Power Systems Society )  5 ( 0 ) 14 - 17   2020

    Introduction and explanation (scientific journal)   Joint Work

     View Summary

    <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>

    Introduction and explanation (scientific journal)   Joint Work

     View Summary

    <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>
