The Effect of Pore Morphology on Hot Spot Temperature

21-11-2014 | George Arthur Levesque, Peter Vitello, Propellants, Explosives, Pyrotechnics, 2014

Abstract Composite explosives contain pores that collapse under shock wave interaction generating localized regions of heat known to be important in the initiation of high explosives. Understanding pore collapse under shock loading is essential to create predictive reactive flow models to ...

Investigation of Crystal Morphology and Shock Sensitivity of Cyclotrimethylenetrinitramine Suspension by Rheology

21-11-2014 | Robert J. Hudson, Mohammed Moniruzzaman, Philip P. Gill, Propellants, Explosives, Pyrotechnics, 2014

Abstract Crystal morphology and shock sensitivity of a series of cyclotrimethylenetrinitramine (RDX) particles suspended from ethylene glycol were investigated. Flow rheology was employed to measure the rheological properties of the suspensions at constant temperature; it was observed that the ...

The Insensitive Energetic Material Trifurazano‐oxacycloheptatriene (TFO): Synthesis and Detonation Properties

17-11-2014 | Xijie Wang, Kangzhen Xu, Qian Sun, Bozhou Wang, Cheng Zhou, Fengli Zhao, Propellants, Explosives, Pyrotechnics, 2014

Abstract The high‐energy insensitive compound trifurazano‐oxacycloheptatriene (TFO) was first by synthesized through special etherification. The reaction mechanism and reaction conditions were discussed. TFO has a low melting point (78.6 °C) and good compatibility. TFO is insensitive to impact ...

Statistical Analysis of an Inter‐Laboratory Comparison of Small‐Scale Safety and Thermal Testing of RDX

17-11-2014 | Geoffrey W. Brown, Mary M. Sandstrom, Daniel N. Preston, Colin J. Pollard, Kirstin F. Warner, Daniel N. Sorensen, Da ..., Propellants, Explosives, Pyrotechnics, 2014

Abstract The Integrated Data Collection Analysis (IDCA) program has conducted a proficiency test for small‐scale safety and thermal (SSST) testing of homemade explosives (HMEs). Described here are statistical analyses of the results from this test for impact, friction, electrostatic discharge, ...

Spaced Armor Effects on Shaped Charge Jet Penetration

17-11-2014 | Bei‐bei Liu, Zheng‐xiang Huang, Xu‐dong Zu, Qiang‐qiang Xiao, Xin Jia, Propellants, Explosives, Pyrotechnics, 2014

Abstract Spaced armor has a simple structure and is easily produced with low cost. Previous authors calculated how a jet penetrates spaced armor; but, this study provides both a theoretical calculation method describing the interaction of a jet with spaced armor and experimental data which ...

Issues Related with Pot Life Extension for Hydroxyl‐Terminated Polybutadiene‐Based Solid Propellant Binder System

17-11-2014 | V. Sekkar, Thakur Sudesh Kumar Raunija, Propellants, Explosives, Pyrotechnics, 2014

Abstract Extension of the pot life for hydroxyl‐terminated polybutadiene (HTPB) based propellant binder systems was attempted through employing a bicurative system comprising of toluene‐di‐isocyanate (TDI) and isophorone‐di‐isocyanate (IPDI). Pot life characteristics were studied through ...

Mechanical Behavior of Nanostructured and Microstructured Explosives

17-11-2014 | Vincent Pichot, Benedikt Risse, Julien Mory, Christelle Nicollet, Fabien Schnell, Marc Comet, Denis Spitzer, Propellants, Explosives, Pyrotechnics, 2014

Abstract Nanostructured hexolites (40/60), (60/40), (80/20) and microstructured hexolite (60/40) powders are pressed by uniaxial compression to obtain explosive charges. This kind of composition is often used for the synthesis of detonation nanodiamonds. The morphology, density and cohesion of ...
