Combustion Wave Structure of the Ammonium Dinitramide‐Based Ionic Liquid Propellant
Propellants, Explosives, Pyrotechnics, Volume 48, Issue 2, February 2023., 2023 Abstract The ammonium dinitramide‐based ionic liquid propellant (ADN‐based ILP), which is a mixture of ADN, monomethylamine nitrate (MMAN), and urea, is a low toxic monopropellant with a higher performance than that of hydrazine. To clarify the combustion wave structure of ADN‐based ILP, which has low volatility, we focused on the relationship between ...

Engineering Reports, Volume 4, Issue 10, October 2022., 2022 The article starts with a discussion of the stoichiometric and non‐stoichiometric methodologies, which are used in order to compute the chemical equilibria for complex reacting systems at fixed conditions. For each one of these two methodologies, author compares the equilibrium compositions obtained using several numerical techniques.
