| Outline of Final Research Achievements |
The purpose of this project is to establish the design guideline of the air intake system for air breathing ion engine (ABIE) both by numerical simulations and experiments. The results of DSMC simulations show that the density of the reflected molecules are concentrated near the center axis of the ABIE. Plasma simulation performed by computational code (EMSES) indicated that the production of the ions in the ABIE increased 5 times by tuning the ABIE design. The experiments using 25% scale ABIE model was carried out. The pressure in the ABIE was measured by the fast ionization gauge. An evaluation method of air intake of ABIE in the orbit (continuous atomic oxygen flow) was successfully established based on the ground-based experiment using beam pulses formed in the laser-detonation beam source.
