Research fields

To develop high-efficiency aerospace propulsion systems, electric propulsions and combustion engines and are studied from the viewpoint of physical gas dynamics. The followings are our recent topics:

  • Research and development of high-power electric Hall thruster systems
    Developments of high-power electric propulsion systems are required for space missions of the manned Mars exploration and the space solar power system. We join the JAXA collaborative research and development """"RAIJIN"""" consisting of multiple Hall thruster heads and conduct experimental and numerical studies.
  • Numerical study on ion engine
    We develop codes for analyses of ion and electron motions in ion sources and neutralizers and analyze non-equilibrium phenomena.
  • Research and development of pulsed plasma thruster (PPT)
    The PPT is an intermittently-operated electric propulsion and has a simple structure, and is promising for attitude controls of large structures and orbital and attitude controls of nano-satellites. To reduce a waste of propellant, optical measurements are conducted for investigations of the phenomena and optimization of PPT operation.
  • Research and development of pulsed detonation engine (PDE)
    The PDE is a high efficiency combustion engine and uses energy generated by pulsed detonation. We conduct studies on shortening deflagration-to-detonation (DDT) distance by supplying vortex flow of fuel-air mixture.
