| Outline of Final Research Achievements |
In this study, pulsed-rocket mode, in-tube driven acceleration mode, and multi-parabola free-flight vehicle were proposed and developed as a type of beamed-energy vehicles driven by an intense electromagnetic beam, and numerical simulation and experiment were conducted. The numerical simulation captured propagation characteristics of a beam-induced plasma, shock wave character, and thrust conversion character to the beamed-energy propulsion system, which indicated that a thrust performance of the beamed-energy vehicle was improved based on the proposed techniques. The simulation result was then validated by conducting the experiment.

| Academic Significance and Societal Importance of the Research Achievements |
ビーム推進システムの研究に従事し，放電特性や推進特性を明らかにする事で推進性能を改善出来たが，これによりビーム推進システムが確立出来れば，ロケット打ち上げコストを従来よりも大幅に削減し，宇宙利用ミッションの頻度を高める事が可能となる．また本研究により，ビーム誘起放電現象におけるエネルギー輸送，輻射輸送過程の一部が解明されたが，工学的観点だけでなくプラズマ物理学的観点からも大変有意義である．
