Reaction of a Particle Suspension in a Rapidly‐Heated Oxidizing Gas

11-May-2015 | Michael Soo, Samuel Goroshin, Jeffrey M. Bergthorson, David L. Frost, Propellants, Explosives, Pyrotechnics, 2015

Abstract The reaction of a suspension of solid particles in a rapidly‐heated oxidizing gas is relevant to metalized explosives and propellants, as well as to combustion of solid fuel‐particle suspensions in premixed‐gaseous‐fuel clouds encountered in accidents within the mining and process ...

The Use of Glass Anvils in Drop‐Weight Studies of Energetic Materials

07-May-2015 | Stephen M. Walley, John E. Field, Richard A. Biers, William G. Proud, David M. Williamson, Andrew P. Jardine, Propellants, Explosives, Pyrotechnics, 2015

Abstract Conventional impact sensitiveness machines (e.g. Rotter and BAM) do not provide detailed information about hot‐spot ignition mechanisms in energetic materials. To gain further insight, a glass anvil technique was developed at Cambridge in the early 1950s, which allowed high‐speed ...

Theoretical and Experimental Study on the Effects of Impact Angle on the Performance of Kevlar Woven Fabric Rubber Composite Armor against Shaped Charge Jet Impact

01-May-2015 | Xin Jia, Zheng‐Xiang Huang, Xu‐Dong Zu, Qiang‐Qiang Xiao, Propellants, Explosives, Pyrotechnics, 2015

Abstract Kevlar woven fabric rubber composite armor (WFRCA) is a type of add‐on armor that usually consists of two steel plates with two Kevlar woven fabrics and a rubber layer in between. In this study, a theoretical model was developed to analyze the effect of the impact angles on the ...

Hydronium Copper(II)‐tris(5‐nitrotetrazolate) Trihydrate – A Primary Explosive

25-Apr-2015 | Mariusz Krawiec, Stephen R. Anderson, Pascal Dubé, David D. Ford, Jerry S. Salan, Shannon Lenahan, Neha Mehta, Clift ..., Propellants, Explosives, Pyrotechnics, 2015

Abstract The long‐time elusive structure of the acid copper(II) salt intermediate in the production of DBX‐1 is presented. The single‐crystal X‐ray shows infinite chains of copper(II) ions complexed by six 5‐nitrotetrazolate anions are aligned along the sixfold axis. Hydronium ions are located ...

Thermochemical, Sensitivity and Detonation Characteristics of New Thermally Stable High Performance Explosives

17-Apr-2015 | Mohammad Hossein Keshavarz, Karim Esmailpour, Mehdi Zamani, Akbar Gholami Roknabadi, Propellants, Explosives, Pyrotechnics, 2015

Abstract The M06‐2X/6‐311G(d,p) and B3LYP/6‐311G(d,p) density functional methods and electrostatic potential analysis were used for calculation of enthalpy of sublimation, crystal density and enthalpy of formation of some thermally stable explosives in the gas and solid phases. These data were ...

Are DTTO and iso‐DTTO Worthwhile Targets for Synthesis?

17-Apr-2015 | Karl O. Christe, David A. Dixon, Monica Vasiliu, Ross I. Wagner, Ralf Haiges, Jerry A. Boatz, the late Herman L. Ammon, Propellants, Explosives, Pyrotechnics, 2015

Abstract Theoretical calculations were carried out for the isomeric di‐1,2,3,4‐tetrazine tetraoxides (DTTO and iso‐DTTO). The most important explosion performance parameters, the detonation pressure and detonation velocity, are dominated by the densities and not by the heats of formation of ...

Experimental Study and DEM Simulation of Micro–Macro Behavior of TATB Granules During Compaction Using X‐ray Tomography

17-Apr-2015 | Bin Dai, Wei‐bin Zhang, Lin‐gang Lan, Yong Tian, Propellants, Explosives, Pyrotechnics, 2015

Abstract In this study, a noninvasive experimental method and a discrete element method (DEM) model were used to investigate the micro–macro behavior of TATB granules including global deformations, contact forces, stress distributions, local coordination number, local pore ratio, particle ...

Thermobaric and Enhanced Blast Explosives – Properties and Testing Methods

16-Apr-2015 | Waldemar A. Trzciński, Lotfi Maiz, Propellants, Explosives, Pyrotechnics, 2015

Abstract The review of the available literature on thermobaric explosives and enhanced blast explosives (high‐destructive explosives) is done in the paper. These types of explosives are defined, their common features and differences are shown. Special attention is paid to the physical ...

Application of Nano‐Aluminum/Nitrocellulose Mesoparticles in Composite Solid Rocket Propellants

16-Apr-2015 | Gregory Young, Haiyang Wang, Michael R. Zachariah, Propellants, Explosives, Pyrotechnics, 2015

Abstract In this work we investigate the potential application of nano‐aluminum/nitrocellulose mesoparticles as an ingredient for solid composite rocket propellants. The basic strategy is to incorporate nanoaluminum in the form of a micrometer scale particle containing a gas‐generator, to ...

CFD Cook‐Off Simulation and Thermal Decomposition of Confined High Energetic Material

16-Apr-2015 | Daniel O. Asante, Shinhyuk Kim, Jooseung Chae, Hyounsoo Kim, Min Oh, Propellants, Explosives, Pyrotechnics, 2015

Abstract The handling, storage and safety before deployment of explosives are major key issues that confront the ammunition industry. Precautions have to be taken not to cause premature detonations and fatal accidents by studying their thermal behaviour. Research has been conducted to ...
