Combustion of Boron Particles in Premixed Methane/Air Flames

05-Feb-2016 | Jan Veith, Michael Pfitzner, Propellants, Explosives, Pyrotechnics, 2016

Abstract Because of its high energy density, boron particles have been a subject of interest for the use as propellant in propulsion systems for many years. A cheap and fast opportunity to investigate multiphase reacting flows in such systems is offered by numerical simulations. Therefore, a ...

Neutron Diffraction Measurements and Micromechanical Modelling of Temperature‐Dependent Variations in TATB Lattice Parameters

02-Feb-2016 | John D. Yeager, Darby J. Luscher, Sven C. Vogel, Bjorn Clausen, Donald W. Brown, Propellants, Explosives, Pyrotechnics, 2016

Abstract Triaminotrinitrobenzene (TATB) is a highly anisotropic molecular crystal used in several plastic‐bonded explosive (PBX) formulations. TATB‐based explosives exhibit irreversible volume expansion (“ratchet growth”) when thermally cycled. A theoretical understanding of the relationship ...

Computational Studies on Nitro, Nitramino, and Dinitramino Derivatives of 1‐Aminoazadiboridine as High Energetic Material

02-Feb-2016 | Satyendra Gupta, Soumitra K. Sengupta, Hari Ji Singh, Propellants, Explosives, Pyrotechnics, 2016

Abstract Computational studies were performed to determine the thermodynamic and explosive characteristics of high energy materials formed by placing explosophores such as nitro (NO2), nitramino (NHNO2), and dinitramino (N(NO2)2) groups on 1‐aminoazadiboridine. G3 level calculations were ...
