In recent years, energetic ionic liquid based ammonium dinitramide (ADN) is drawing attention as green monopropellant alternate of hydrazine. Energetic ionic liquid is promising new monopropellant because it has high density, high specific impulse, and low toxicity. However, it is difficult to atomize due to its high viscosity. Therefore, it has ignition and combustion characteristics issue and not in practical use. In this study, we tried adding an additive to decrease viscosity of ADN-based energetic ionic liquid to improve its atomization characteristics. Viscosity measurement and chemical calculation by NASA CEA were performed to find suitable additive material for ADN-based green propellant. As a result, it is found that 20 wt% of methanol is suitable for additive because of viscosity, atomization characteristics, and exhaust characteristics velocity.
