The liquefaction of high energetic materials without solvents can lead to increase of performances liquid propellants. We focused on energetic ionic liquids (EILs) and their applicability was investigated. In this study, we were able to prepare energetic ionic liquid propellants (EILPs) based on high energetic oxidizer ammonium dinitramide (ADN) by forming eutectic systems with monomethylamine nitrate (MMAN) and Urea. Chemical equilibrium computation results showed that the ADN-based EILPs have higher performance than existing propellant, hydrazine. From the thermal behavior of the ADN-based EILPs with constant rate heating, all of them decomposed to gas and generate N2O, NO2, N2, NH3, HNCO, CO2, and H2O. We have studied about their physical properties, decomposition mechanism and combustion mechanism, and aimed at solving the problems for realization such as viscosity, ignition method, and at designing EILPs.
