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.

Propellants, Explosives, Pyrotechnics, EarlyView.Ammonium dinitramide (ADN) and 3,4‐Diaminofurazan (DAF) form a 1:1 energetic cocrystal. We report its crystal structure and spectroscopic signature and evaluate thermal stability, decomposition behavior, hygroscopicity, and combustion properties. Propellant performance calculations benchmark the material against guanylurea dinitramide (GuDN) and ...

Research Progresses of Flash Evaporation in Aerospace Applications
International Journal of Aerospace Engineering, Volume 2018, Issue 1, 2018., 2018 Liquid is overheated and evaporated quickly when it enters into the environment with lower saturation pressure than that corresponding to its initial temperature. This phenomenon is known as the flash evaporation. A natural low‐pressure environment and flash evaporation have unique characteristics and superiority in high altitude and outer space ...
