Abstract. Energetic ionic liquids (EILs) containing ammonium dinitramide (ADN) as the primary component have attracted considerable attention as new liquid propellants for rocket propulsion. AMU is a candidate composition for ADN-based EILs, which involves blending monomethylamine nitrate and urea with ADN as the fuel components. A major concern with ADN-based EILs is their pronounced hygroscopic nature during handling and storage. The influence of moisture contamination on the combustion behavior of AMU remains insufficiently understood. Consequently, this study aims to investigate the influence of contaminant water on the combustion characteristics of AMU by conducting ignition and combustion tests to assess parameters such as the ignition temperature, combustion rate, and combustion temperature. The findings indicate that the presence of water increases the ignition temperature while decreasing the combustion temperature of the AMU mixture.
