Combustion of ammonium dinitramide

Combustion and Flame, 1999
The burning rate of ammonium dinitramide (ADN) has been studied as a function of pressure and different additives, the temperatures in the combustion front, and the composition of combustion products. Some kinetic characteristics of decomposition have been also obtained.

Combustion of Propellants with Ammonium Dinitramide

Propellants, Explosives, Pyrotechnics, 1998
AbstractThis paper reports a series of experiments involving ammonium dinitramide (ADN), a new energetic oxidizer of potential use in composite solid propellants. The experiments include (a) self‐deflagration of pressed pellets of ADN; (b) combustion of sandwiches with ADN laminae on both sides of a binder lamina that is either “pure” or filled with ...

Thermal stability of ammonium dinitramide

Thermochimica Acta, 2002
Abstract The low temperature thermal stability of ammonium dinitramide (ADN) and efforts to improve the thermal stability are presented. The decomposition rates of ADN at 60, 70, 80, and 90 °C were investigated. Several potential thermal stabilizers were investigated to suppress the low temperature decomposition (60–90 °C) of ADN.

Comparative DFT Study of Crystalline Ammonium Perchlorate and Ammonium Dinitramide

The Journal of Physical Chemistry A, 2008
The electronic structure, vibrational properties, absorption spectra, and thermodynamic properties of crystalline ammonium perchlorate (AP) and ammonium dinitramide (ADN) have been comparatively studied using density functional theory in the local density approximation.

Thermal Analysis of Ammonium Dinitramide Decomposition

Propellants, Explosives, Pyrotechnics, 1997
AbstractThe new energetic material ammonium dinitramide (ADN), NH4N(NO2)2, has been investigated with regard to its thermal properties and decomposition behavior. Thermal decomposition of ADN is observed after complete melting at 91.5 °C. The main decomposition pathway is based on the formation of NH4NO3 and N2O followed by the thermal decomposition of

Energetics of ammonium dinitramide decomposition steps

Journal of Molecular Structure: THEOCHEM, 1998
Abstract The structures, energies at 0 K and enthalpies at 298 K have been computed for 37 molecules, ions and transition states that have been implicated in the thermal decomposition of ammonium dinitramide. A density functional procedure was used: DF/B3P86/6–31 + G ∗∗.

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 ...

Investigating the Reaction‐Mechanistic Effects of Nitrogenous Gases on the Thermal High‐Temperature Decomposition of Ammonium Dinitramide‐Based Liquid Propellant: Insights From Reactive Molecular Simulations

Propellants, explosives, pyrotechnics
The thermal decomposition of ammonium dinitramide (ADN)‐based liquid propellant (ALP), which is composed of 63.4% ADN, 25.4% H2O, and 11.2% CH3OH by mass fraction, is significantly influenced by nitrogenous gases.

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 ...
