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 ...

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.A high‐performance premixed monopropellant is prepared from hydrocarbon‐filled microcapsules and hydrogen peroxide. This propellant is burned in a strand burner, and the effect of different parameters on the burn rate is evaluated. ABSTRACT A dispersion of hydrocarbon‐fuel‐filled microcapsules in gelled hydrogen peroxide can form a premixed ...
