Proton transfer in gas-phase ammonium dinitramide clusters

, 2003
Proton transfer in gaseous ammonium dinitramide (ADN) clusters up to (ADN)2 is studied by using density-functional theory. Proton transfer between the hydrogen dinitramide and ammonia units does not occur in the ADN monomer, rather the ammonia ...

An overview on properties, thermal decomposition, and combustion behavior of ADN and ADN based solid propellants

Defence Technology, 2018
Ammonium dinitramide [NH4N(NO2)2, ADN] is considered as a possible replacement for ammonium perchlorate (AP) in nearly all kind of solid rocket propulsions in the coming future. The reason to use ADN instead of AP in solid rocket propulsion is because of

The anomalous solid state decomposition of ammonium dinitramide: a matter of surface polarization

, 2009
Polarized dinitramide anions on the surface of solid ammonium dinitramide (ADN) have a decomposition barrier that is reduced by 16 kcal mol(-1) and explain the anomalous solid state decomposition of ...

Characterisation and thrust measurements from electrolytic decomposition of Ammonium Dinitramide (ADN) based liquid monopropellant FLP-103 in MEMS thrusters [PDF]

, 2017
Although Ammonium Dinitramide (ADN) has been targeted as a potential green monopropellant in future space vehicles, its application potential in Micro-electrical-Mechanical System (MEMS) thrusters or microthrusters have seldom reported in open literature.
