Thermal Ignition of ADN‐Based Propellants
Propellants, Explosives, Pyrotechnics, Volume 44, Issue 9, Page 1096-1106, September 2019., 2019 Abstract Ammonium dinitramide (ADN, NH4+ N(NO2)2−) based monopropellants are extremely promising as hydrazine replacement. Thermal igniters are attractive for ADN thrusters as they allow a more prompt ignition and may be better suited for larger engines (100‐500 N) compared to the currently used preheated catalysts.

Multidisciplinary Design Optimization and Analysis of Hydrazine Monopropellant Propulsion System
International Journal of Aerospace Engineering, Volume 2015, Issue 1, 2015., 2015 Monopropellant propulsion systems are widely used especially for low cost attitude control or orbit correction (orbit maintenance). To optimize the total propulsion system, subsystems should be optimized. Chemical decomposition, aerothermodynamics, and structure disciplines demand different optimum condition such as tank pressure, catalyst bed length ...
