Outline of Final Research Achievements

Electric propulsion have a capability of high-exhaust velocity operation than that of the chemical propulsion operation. However, due to the small thrust, it takes much longer time to orbit rising. In this research, the electrostatic/magnetic hybrid ion acceleration method under the diverging magnetic field was investigated to achieve a large-thrust operation of electric propulsion. Through this research, we have hound that even with external cathode operation, the hybrid ion acceleration method was effective by keeping high electron Hall parameter. By increasing magnetic field strength, multiple ionization process was enhanced. As as result, the specific impulse exceeded 3800 s and more than 30% of thrust efficiency was achieved with argon propellant.

Academic Significance and Societal Importance of the Research Achievements

多くの宇宙推進機は低い電離エネルギーを有するキセノン推進剤を使用している.しかしながらキセノン推進剤は年間生産量が限定されその価格は高騰し続けている.そこで本提案手法である静電/電磁混合イオン加速をアルゴン推進剤に対して適用することでキセノン推進機に対して1/200の価格でありながら,これまでにない電気推進機の高排気速度作動を実現することができた.本成果は宇宙機の運用コスト削減に大きく貢献するものと考えられる.
