Detailed kinetic model for ammonium dinitramide decomposition
Combustion and Flame, 2018 Abstract Ammonium dinitramide (ADN; [NH4]+[N(NO2)2]−) is the most promising oxidizer for use with future green solid and liquid propellants for spacecraft applications. To allow the effective development and use of ADN-based propellants, it is important to understand ADN reaction mechanisms.
