| Outline of Final Research Achievements |
Investigation of propellant flow of ion thruster is required to improve ion thruster performance. Since few measurement systems can detect the pressure because the propellant pressure is rarefied, in this research, a low pressure measurement system with a precise differential pressure gauge had been developed. Through the evaluations with a thruster, it had been confirmed that the accuracy of this measurement system was enough to discuss the influence of the rarefied propellant flows, for the researches on account of not only ion thruster but also the other electric propulsion and test facility effect.
