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.
