Welcome to Keita Nishii's homepage. I am working on both electric and chemical propulsion systems for spacecraft. In particular, I am researching and developing new propulsion systems for use on small spacecraft. I am also investigating the effects of ground tests on the propulsion systems that will eventually be used in space through experiments and numerical simulations.
Research Interests: Space propulsion / Electric propulsion / Micropropulsion / CubeSat / Resistojet / Hybrid rocket / Green propellant / Metal combustion / Microgravity / Thermal engineering / Rarefied gas dynamics / High-performance computing
