Calculation of decomposition products from components of gunpowder by using ReaxFF reactive force field molecular dynamics and thermodynamic calculations of equilibrium composition
(2014)
The major combustion products from munitions containing nitro-based propellants are water, carbon monoxide, carbon dioxide, hydrogen and nitrogen. In addition, compounds including hydrogen cyanide, ammonia, methane, nitrogen ...
Curing of Glycidyl Azide Polymer (GAP) diol using isocyanate, isocyanate-free, synchronous dual, and sequential dual curing systems
(2015)
Glycidyl azide polymer (GAP) is an important energetic
binder candidate for new minimum signature solid composite rocket propellants, but the mechanical properties of such GAP propellants are often limited. The mechanical ...
Mechanical Properties of Smokeless Composite Rocket Propellants Based on Prilled Ammonium Dinitramide
(2012)
Ammonium dinitramide (ADN) is a high performance solid oxidizer of interest for use in high impulse and smokeless composite rocket propellant formulations. While rocket propellants based on ADN may be both efficient, clean ...
Neutral Polymeric Bonding Agents (NPBA) and Their Use in Smokeless Composite Rocket Propellants Based on HMXGAP- BuNENA
(2012)
Very few efficient bonding agents for use in solid rocket propellants with nitramine filler materials and energetic binder systems are currently available. In this work, we report the synthesis, detailed characterization, ...
Micro indentation hardness testing of commercial-grade RDX crystals
(2016)
This paper describes the continuous micro indentation hardness testing of two
commercial grades of RDX with differing shock sensitivities using three (3)
different loads on a Berkovich indenter to obtain values of elastic ...
All Molecular Surfaces are Equal: Demanding Invariance of Predictions in Linear Single-Variable Models
(2016)
The molecular surface has been suggested to be a region of the molecule where information of non-covalent intermolecular interactions is present. Many workers have pursued this idea by constructing models based on statistical ...
A Study of the Detonation Properties, Propellant Impulses, Impact Sensitivities and Synthesis of Nitrated ANTA and NTO Derivatives
(2016)
Nitrated derivatives of 5-amino-3-nitro-1,2,4-triazole (ANTA)
and 3-nitro-1,2,4-triazol-5-one (NTO) were theoretically characterized with respect to their performance as high explosives and rocket propellants. The detonation ...
Isocyanate-Free and Dual Curing of Smokeless Composite Rocket Propellants
(2013)
Traditional composite rocket propellants are cured by treatment of hydroxyl-terminated prepolymers with polyfunctional aliphatic isocyanates. For development of smokeless composite propellants containing nitramines and/or ...
Study of thermal instability of HMX crystalline polymorphs with and without molecular vacancies using reactive force field molecular dynamics
(2016)
The sensitivity of energetic materials can be identified by heat, friction, impact, shock, electrostatic charge, etc. A complexity of various factors may influence the sensitivity and among them are the crystal structure ...
A computational study of density of some high energy molecules
(2016)
The detonation pressure depends quadratically on the loading density of the explosives. A precise estimate of the density is thus crucial to decide if a novel energetic material is worth pursuing. In this work we investigate ...
