Condensed Phase Behavior in the Combustion of Ammonium Dinitramide

09-04-2014 | Koji Fujisato, Hiroto Habu, Keiichi Hori, Propellants, Explosives, Pyrotechnics, 2014

Abstract This paper reports on the thermal and combustion behaviors of ammonium dinitramide (ADN). The thermal behavior is measured by a pressure thermogravimetric analysis (TGA) at pressures below 8 MPa. The burning rates of pure ADN and ADN/ammonium nitrate (AN) mixtures are measured in the ...


The Role of Fuel Particle Size on Flame Propagation Velocity in Thermites with a Nanoscale Oxidizer

07-04-2014 | Kyle T. Sullivan, Joshua D. Kuntz, Alexander E. Gash, Propellants, Explosives, Pyrotechnics, 2014

Abstract The effect of aluminum size on confined flame propagation velocities in thermite composites was investigated between 108 μm and 80 nm, and in all cases using nanometric copper oxide as the oxidizer. It was found that the velocity exhibited two distinct regimes; between 108 and 3.5 μm ...


Energetic Derivatives of 2‐Nitrimino‐5,6‐dinitro‐benzimidazole

07-04-2014 | Thomas M. Klapötke, Andreas Preimesser, Jörg Stierstorfer, Propellants, Explosives, Pyrotechnics, 2014

Abstract 2‐Nitrimino‐5,6‐dinitrobenzimidazole (1) was synthesized by nitration of 2‐aminobenzimidazole at ambient temperature in good yield. In order to explore new insensitive explosives four energetic nitrogen‐rich 1 : 1 salts such as the guanidinium (1a), aminoguanidinium (1b), ...


Preparation of Nano‐RDX by Evaporation Assisted SolventAntisolvent Interaction

07-04-2014 | Raj Kumar, Prem F. Siril, Pramod Soni, Propellants, Explosives, Pyrotechnics, 2014

Abstract Nanoparticles of cyclotrimethylenetrinitramine (RDX) were prepared by a simple re‐precipitation method using acetone as solvent and water as the antisolvent. The effect of changing experimental parameters such as ratio of solvent to antisolvent, temperature of antisolvent during ...


Synthesis and Desensitization of Nano‐β‐HMX

07-04-2014 | Benedikt Risse, Fabien Schnell, Denis Spitzer, Propellants, Explosives, Pyrotechnics, 2014

Abstract Efforts are made worldwide to desensitize explosives against accidental initiation. For several years, nanostructuring of explosives is a promising field of research aiming for this goal. In this work we describe the continuous preparation of nano‐β‐HMX and a promising approach ...


Replacing the Equations of Fano and Fisher for Cased Charge Blast Impulse – III – Yield Stress Method

07-04-2014 | Michael D. Hutchinson, Propellants, Explosives, Pyrotechnics, 2014

Abstract Previous papers by the author [1–3] pointed to a discovery by Fisher [4] that an equation by Fano [5], when used to predict blast impulse from cased munitions, did not fit the available data. These previous papers showed that an alternative equation for casing‐modified blast impulse ...


Shaped Charge Liner Early Collapse Experiment Execution and Validation

07-04-2014 | Eric Scheid, T. David Burleigh, Nishkamraj U. Deshpande, Michael J. Murphy, Propellants, Explosives, Pyrotechnics, 2014

Abstract A novel experiment developed for researching the initial collapse of an aluminum shaped charge liner was designed, executed, and validated. The experiment evolved from the need to recover shocked liner material to enable the analysis of relationships between microstructure and early ...


Properties and Application of a Novel Type of Glycidyl Azide Polymer (GAP)‐Modified Nitrocellulose Powders

28-03-2014 | Yanguang Wu, Yunjun Luo, Zhen Ge, Propellants, Explosives, Pyrotechnics, 2014

Abstract GAP‐modified nitrocellulose powders were prepared by an internal solution method and applied in cross‐linked modified double base (XLDB) propellants. It was found that GAP‐modified nitrocellulose powders exhibit high round, no bonding between the particles and excellent fluidity. When ...


The Effect of Silicon Powder Characteristics on the Combustion of Silicon/Teflon/Viton Nanoenergetics

18-03-2014 | Brandon C. Terry, Ya‐Cheng Lin, Khachatur V. Manukyan, Alexander S. Mukasyan, Steven F. Son, Lori J. Groven, Propellants, Explosives, Pyrotechnics, 2014

Abstract Due to its thin passivation layer, potentially good aging characteristics, and ease of surface functionalization nanoscale silicon (Si) may offer some advantages over nanoaluminum as a reactive fuel in nanoenergetic compositions, particularly with fluorine‐based oxidizers. Currently, ...


Facile Preparation of Self‐Sensitized FOX‐7 with Uniform Pores by Heat Treatment

18-03-2014 | Tingting Li, Rui Li, Fude Nie, Jun Wang, Weigang Huang, Guangcheng Yang, Propellants, Explosives, Pyrotechnics, 2014

Abstract Self‐sensitized FOX‐7 (1,1‐diamino‐2,2‐dinitroethylene) was prepared by a facile heat treatment process near the decomposition temperature. Field emission scanning electron microscopy (FE‐SEM) shows the self‐sensitized FOX‐7 becomes multiple layers and porous after heat treatment. N2 ...
