| Outline of Final Research Achievements |
An experimental research was conducted on bi-propellant thrusuter which uses sodium and water as propellant. Sodium was liquified by heating up to 98 degrees cersius, which is its melting point.
In the experiment of injector, much amount of non-reacted sodium was observed in the chamber after injection. In order to promote the reaction of these two propellant, water was injected from multiple injector holes toward one liquid sodium column. Using this type of injector, sodium-water bipropellant thruster was successfully fired.
