Advanced technology has to be developed for a spacecraft and a launch vehicle to achieve the next-generation development of space technology, such as a deep space exploration and a solar power satellite. We have conducted researches for the development of the advanced spacecraft and the advanced space vehicle system; the key word of our researches is “active flow control”. One of our research topics is “Electrodeless Acceleration of High Density Plasma”. The objective of this study is to develop the electromagnetic plasma acceleration technique using a magnetic nozzle and Radio-Frequency rotating electric field. This technique achieves an advanced plasma thruster, which is high-thrust and long-lived space propulsion system. Second research topic is “Flow Control Technique Using Dielectric Barrier Discharge”. DBD plasma actuator gets much attention as an attractive flow control device utilizing dielectric barrier discharge; however, enhancement of the output power is required for actual use. In this study, the physical mechanism of the flow control by the dielectric barrier discharge has been investigated by experimental and numerical approaches, and we will propose the improvement method of the actuator. The last one of our research topics is “Active Flow Control of Separation Flow over a Flight Object”. This study is for the development of an advanced air plane and space plane. Flight condition of a space plane is more severe than that of conventional air plane, and the space plane should have high aerodynamic performance under various flight conditions. The active control of the separation flow over the airframe is one of promising solutions for this problem. We have proposed the flow control concept using DBD plasma actuator on a high-angle -of-attack slender body, and the investigation has been conducted to validate our concept.
I think the tenure-track post is attractive for a young researcher. We take great responsibility for teaching students and running an independent laboratory, however, for that reason, I find great satisfaction for my works. Especially, in the tenure-track post, a researcher can set research themes on one’s own, and that is the most attractive point of the tenure-track post. I think I can become a self-sustaining researcher by overcoming the hardships for getting the tenure post.
Technical breakthroughs in various areas are required for inspiring future space explorations such as the space tourism and the space colony. I want to set research themes by seeing the long-term direction of space technology advances, and I will keep trying to investigate advanced and innovative technologies in the research fields of plasma engineering and aerodynamics. I wish to get significant results by research based on a creative idea, and contribute to the growth of space technology.
