Outline of Final Research Achievements |
This project is to advance the research and development of three types of propulsion systems using water as a propellant at the satellite system level and to realize them as space propulsion systems for nano-satellites. In the first type, ion thrusters, research on plasma physics and engineering application has been conducted both experimentally and numerically, and unexpected plasma instability has been found and space applications have been achieved. The second, the resistojet thruster, was reached to the flight-ready level at an early stage, and the proposed new system utilizing the waste heat from spacecraft was actually equipped on the nano-satellite. In the third, the metal hybrid thruster, we succeeded in combusting metal under low-pressure steam, which opened up a new space propulsion system leading to several associated reseach prgrams.
