Research Outline  

It is necessary to carry out more deep space explorations for the development of solar system science. A space propulsion system (rocket) is required for satellites that perform deep space explorations beyond the moon.

A chemical rocket is required to achieve a mission in a short period, but it is difficult to handle liquid and solid rockets that use dangerous materials. A hybrid rocket uses a propellant that combines solid and liquid phases. Because the hybrid rocket does not use explosives and dangerous substances, its safety management is not expensive. Therefore, the hybrid rocket is one of the solutions for making deep space exploration more active.

I focus on a new innovative hybrid rocket that formed by micro-diffusion flames. In addition, I aim to further improve the performance by investigating the basic combustion phenomena of the innovative hybrid rocket. Through interdisciplinary research, industry-academia/international collaborations, I will conduct a space demonstration of the innovative hybrid rocket and contribute to the development of solar system science.
