| Outline of Final Research Achievements |
This study focused on new liquid propellant for space propulsion, “ammonium dinitramide (ADN)-based ionic liquid propellant” to replace hydrazine. To construct composition of propellant, eutectic behavior between ADN and various materials were observed and a guide to prepare ionic liquid with low melting point was investigated. This study made it possible ignite the droplet of ADN-based ionic liquid using laser. In addition, to get a better understanding of characteristics of thermal decomposition and combustion, simultaneous analysis of thermal behavior and evolved gas during reaction were carried out and their reaction mechanism were presumed. These results showed feasibility of ADN-based ionic liquid for propellants.
