Ammonium dinitramide (ADN) based energetic ionic liquids (EILs) has been expected as a next generation propellant. Since ADN-based EILs are thermally stable, it is difficult to ignite using thermal ignition methods. Our research group focused on an ignition method of the EILs applying a voltage (electrolysis ignition). Previous studies have theoretically reported the possibility of ignition of ADN-based EILs and experimentally demonstrated the ignition. It is necessary to extend the basic electrolysis and ignition properties for the development of the ignition technique. The purpose of this study is to select suitable compositions for electrolysis ignition and analyze the effect of electrolysis parameters. In this study, a voltage is applied to ADN-based EILs droplet and the behavior were captured using a high-speed camera. The time from applying voltage to forming the flame was defined as the electrolysis ignition time. Experimental results revealed the binary EILs of ADN and monomethylamine nitrate (MMAN) was more suitable for electrolysis ignition than the other EILs used in this study. The electrolysis ignition time of ADN/MMAN was measured using a high-speed camera in each electrolysis parameter. The results showed the electrolysis ignition time tended to shorten by increasing the applied voltage and electrodes surface area.
