Kinetics analysis of thermal decomposition of ammonium dinitramide (ADN)
Journal of Thermal Analysis and Calorimetry, 2016Kinetics analyses were performed on the thermal decomposition of ammonium dinitramide (ADN) using thermogravimetry-differential thermal analysis–mass spectrometry–infrared spectroscopy (TG-DTA–MS–IR). The main evolved gases were determined to be NH3, H2O, N2, NO, N2O, and NO2.

Crystallization of Spherical Ammonium Dinitramide (ADN) Particles
Propellants, Explosives, Pyrotechnics, 2000The described process aims to produce spherical ammonium dinitramide (ADN) particles of different sizes with a narrow particle size distribution. The crystallization process presented in this paper consists of two stages. In the first stage, molten ADN is dispersed in a continuous phase in which ADN is insoluble.

Ammonium Dinitramide (ADN)–Prilling, Coating, and Characterization
Propellants, Explosives, Pyrotechnics, 2009AbstractAmmonium dinitramide (ADN) is the promising oxidizer, which is expected to be applied, e.g., in solid rocket propellants. The manufacturing of spherical ADN particles (the so‐called ADN‐Prills) with useful morphology and reproducible quality is realized by means of the emulsion crystallization process.

Nanocrystallisation of Ammonium DiNitramide (ADN) by Spray Flash Evaporation (SFE)
Propellants, Explosives, Pyrotechnics, 2018AbstractAmmonium DiNitramide (ADN) is an interesting oxidizer to replace ammonium perchlorate in the composition of solid propellants. In this study, Spray Flash Evaporation (SFE) is presented as a new technology to enhance stability of ADN by crystallization of nanoparticles.

Thermal analysis of ammonium dinitramide (ADN)
Thermochimica Acta, 2000Abstract Kinetic constants of decomposition were determined for ADN and prilled ADN by DSC and TG. Pressure DSC at 550 psi air or helium had similar kinetic constants for prilled ADN, namely 29 kcal/mol activation energy and a log frequency factor of ∼14.0 min−1.

Flight Heritage of Ammonium Dinitramide (ADN) Based High Performance Green Propulsion (HPGP) Systems
Propellants, Explosives, Pyrotechnics, 2019AbstractThe flight heritage for ECAPS’ propulsion technology based of Ammonium DiNitramide (ADN), started 2010 with a successful 5 years on orbit demonstration mission of the PRISMA satellite. Since 2016, launches of satellites from 3 different continents continues to add to the flight heritage.

AbstractIn recent years, there has been a considerable interest in the development of novel type of high performance propellants for use in solid rocket motors. Ammonium salt of dinitramidic acid NH4N(NO2)2 (ADN) has attracted wide interest as a potentially useful energetic oxidizer for rocket propellants because of its clean and environment‐friendly ...

CO2 Laser-Induced Combustion of Ammonium Dinitramide (ADN)
Combustion and Flame, 1998Abstract Experimental studies of CO 2 laser-induced combustion of ammonium dinitramide (ADN) were performed to determine the key physical and chemical processes involved. Experimental conditions covered the range of 0.1–5.0 atmospheres in argon and incident laser heat fluxes of 20 to 300 W/cm 2 . Quantitative gaseous species measurements obtained by

Abstract The decomposition and combustion characteristics of ammonium dinitramide (ADN) based non-toxic aerospace propellant are analytically studied to determine the effects of catalytic bed structure (slenderness ratio) and operation parameters (mass fraction ratio of ADN/CH3OH) on the general performance within the ADN-based thruster.

Modeling the Chemical Reactions of Ammonium Dinitramide (ADN) in a Flame
Combustion and Flame, 2001Ammonium dinitramide (ADN) is a new energetic material that can be used as an oxidizer in solid rocket propellants. In the last few years, a number of papers devoted to the study of ADN combustion mechanism have been published. Molecular beam mass-spectrometry and thermocouple measurements are here used to study ADN flame structure at pressures of 0.3 ...
