Role of Additives in the Combustion of Ammonium Dinitramide

Propellants, Explosives, Pyrotechnics, 2014
AbstractThe thermal decomposition behavior and combustion characteristics of mixtures of ammonium dinitramide (ADN) with additives were studied. Micrometer‐sized particles of Al, Fe2O3, TiO2, NiO, Cu(OH)NO3, copper, CuO, and nanometer‐sized particles of aluminum (Alex) and CuO (nano‐CuO) were employed.

Combustion of ammonium dinitramide/polycaprolactone propellants

Proceedings of the Combustion Institute, 2002
This paper is devoted to the investigation of characteristics and mechanisms of combustion of a compositesolid rocket pseudo-propellant of stoichiometric composition based on ammonium dinitramide (ADN) and polycaprolactone (PCL). Experimental data on the dependence of burning rate on pressure in the pressure range of 4–8 MPa for the ADN/PCL propellant ...

Ammonium Dinitramide (ADN)–Prilling, Coating, and Characterization

Propellants, Explosives, Pyrotechnics, 2009
AbstractAmmonium 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.

On the mechanism of thermal decomposition of ammonium dinitramide (review)

Combustion, Explosion, and Shock Waves, 2016
Despite significant progress in studying thermal decomposition of ammonium dinitramide (ADN), the kinetics of the process at the level of elementary stages has not been adequately understood. The aim of this review is to summarize various published data, which are of interest for studying and simulating the processes of thermal decomposition and ...

Ammonium Dinitramide:  Kinetics and Mechanism of Thermal Decomposition

The Journal of Physical Chemistry A, 1997
Thermal decomposition of ammonium dinitramide (ADN) has been studied by differential scanning calorimetry (DSC) and thermal gravimetry combined with mass spectrometry (TG−MS). ADN decomposes in the range 130−230 °C with an overall heat release of 240 ± 40 kJ mol-1.

Ammonium Dinitramide−Water:  Interaction and Properties

Journal of Chemical & Engineering Data, 2006
The interaction between ammonium dinitramide (ADN) and water was experimentally investigated by determining the solid−liquid phase diagram for the system ADN−water and by measuring its critical relative humidity at 25 °C. Additionally, the density of aqueous ADN solutions of different compositions were measured in the temperature range from (5 to 85 ...

Design of an ammonium dinitramide compatible polymer matrix

Journal of Applied Polymer Science, 2011
AbstractTo enable future environmentally friendly access to space by means of solid rocket propulsion a viable replacement to the toxic ammonium perchlorate (AP) oxidizer is needed. Ammonium dinitramide (ADN) holds great promise as a green replacement. Unfortunately compatibility issues with many polymer binder systems have hampered the development of ...

Review of Ammonium Dinitramide Toxicity Studies

2011
Abstract : Ammonium dinitramide (ADN) is a class 1.1 explosive oxidizer being considered for use in solid rocket propellant mixtures. Studies performed evaluating the toxicity of ADN have included an acute and subacute toxicity screen, a 90-day reproductive screen and three follow-on reproductive studies, electron paramagnetic resonance (EPR ...

Separation of Ammonium Dinitramide from Reaction Mixture

Propellants, Explosives, Pyrotechnics, 1999
To separate ammonium dinitramide from the reaction mixture obtained in the reaction between NO2HS2O7 and nitramine in aceto-nitrile and subsequent neutralization with NH3 aqua the following procedure was applied: – separation of the solid precipitated during the reactions; – evaporation of the acetonitrile solution; – extraction of the ...
