Novel High-Nitrogen Content Energetic Compounds with High Detonation and Combustion Performance for Use in Plastic Bonded Explosives (PBXs) and Composite Solid Propellants

High-nitrogen Compounds for Use in Low-erosivity Gun Propellants

Nitrogen rich compounds are suitable as ingredients in low smoke propellant charges. Several high-N energetic materials are presented which are based on tetrazoles. Tetrazoles are an unique class of compounds, since they combine a high nitrogen content and a high heat of formation with good thermal and kinetic stabilities due to their aromatic ring system. The reaction of 5azidotetrazole with h...

بررسی استفاده از پلیمرها و نرم کننده‌های پرانرژی در ساخت مواد منفجره پلاستیکی حاوی HMX

Plastic Bonded Explosives with inert binder despite having good mechanical properties and low sensitivity, because of containing inert materials, have low energy level. So investigations for replacing inert binder system with energetic binder system and high exploding components in the making of these materials are performing. It seems using energetic polymers and materials like Cyclotetramethy...

COMBUSTION PERFORMANCE OF Ni-COATED AND UNCOATED HIGH ENERGETIC ALUMINUM NANOPARTICLES

High energetic aluminum nanoparticles are mainly used as additive in solid rocket propellants. However, fabrication of these aluminized energetic materials is associated with decreasing the burning rate of propellants due to problems such as oxidation and agglomeration of nanoparticles. In this study, to improve combustion performance of aluminum nanoparticles, coating by metallic Ni shell...

A Statistical Hot Spot Reactive Flow Model for Shock Initiation and Detonation of Solid High Explosives

Phenomenological reactive flow models for the shock initiation and detonation of solid high explosives, such as the Ignition and Growth model and the Johnson-Tang-Forest (JTF) model have been very successful in reproducing most of the main features of these reactive flows. The reaction rate expressions in these models depend upon the average compressions and pressures attained in the reacting e...
