, Ammonium dinitramide (ADN) is the ammonium … Ammonium dinitramide (ADN) is the ammonium salt of . ADN decomposes under heat to leave only nitrogen, oxygen, and water. The ions are the ammonium ion NH4+ and the dinitramide N(NO2)2−. It makes an excellent solid rocket oxidizer with a slightly higher specific impulse than ammonium perchlorate and more importantly, does not leave corrosive hydrogen chloride fumes. This property is also of military interest because halogen-free smoke is harder to detect. It decomposes into low-molecular-mass gases so it contributes to higher performance without creating excessive temperatures if used in gun or rocket propellants. The salt is prone to detonation under high temperatures and shock more so than the perchlorate. The EURENCO Bofors company produced LMP-103S as a 1-to-1 substitute for hydrazine by dissolving 65% ammonium dinitramide, NH4N(NO2)2, in 35% water solution of methanol and ammonia. LMP-103S has 6% higher specific impulse and 30% higher impulse density than hydrazine monopropellant. Additionally, hydrazine is highly toxic and carcinogenic, while LMP-103S is only moderately toxic. LMP-103S is UN Class 1.4S allowing for transport on commercial aircraft, and was demonstrated on the Prisma satellite in 2010. Special handling is not required. LMP-103S could replace hydrazine as the most commonly used monopropellant. The ADN-based monopropellant FLP-106 is reported to have improved properties relative to LMP-103S, including higher performance (ISP of 259 s vs. 252 s) and density (1.362 g/cm3 vs. 1.240 g/cm3).and density (1.362 g/cm3 vs. 1.240 g/cm3).

, Le dinitramide d'ammonium (ADN, pour ammon … Le dinitramide d'ammonium (ADN, pour ammonium dinitramide en anglais) est un composé chimique de formule [NH4]+[N(NO2)2]−. Il s'agit formellement du sel d'ammoniac NH3 et d'acide dinitraminique HN(NO2)2. Il a été découvert initialement en URSS mais son développement est demeuré classifié jusqu'à sa découverte indépendante aux États-Unis en 1989 par SRI International, un institut de recherche à but non lucratif émanant de l'université Stanford, en Californie ; c'est lorsque le SRI breveta cette molécule, au milieu des années 1990, que des chercheurs Soviétiques firent savoir qu'ils l'avaient découverte dans les années 1970. L'ADN est un ergol solide oxydant possédant une impulsion spécifique légèrement plus élevée que celle du perchlorate d'ammonium NH4ClO4. Ce dernier est un constituant essentiel des propergols composites à perchlorate d'ammonium (PCPA), lesquels présentent l'inconvénient de libérer des vapeurs de chlorure d'hydrogène HCl ; a contrario, le dinitrate d'ammonium ne libère que des composés non toxiques de faible masse moléculaire, ce qui le fait étudier comme alternative plus « écologique » au perchlorate d'ammonium. « écologique » au perchlorate d'ammonium.
