Double Base Propellants (DBP) has been frequently utilized in the fields of rocket propellant and gun propellant. DBP various advantages over conventional propellants, including easy formulation, high energy, smokelessness. The research conducted literature studies was applied by referring to energetic materials for DBP. composition a consists raw material Nitrocellulose (NC) Nitroglycerin (NG)...
Currently, several green propellants are under investigation to replace the toxic and carcinogenic monopropellant hydrazine . Beside alternatives as ammonium dinitramide-based propellants, hydroxylammonium nitrate-based mixtures, or high concentrated hydrogen peroxide, mixtures of fuels with nitrous oxide called HyNOx NOFBX represent promising propellants. Compared classical , offer a higher pe...
Environmental investigations have been conducted at 23 military firing ranges in the United States and Canada. The specific training facilities most frequently evaluated were hand grenade, antitank rocket, and artillery ranges. Energetic compounds (explosives and propellants) were determined and linked to the type of munition used and the major mechanisms of deposition.
Composite solid propellants are materials that constitute from an oxidizer, an organic binder, a metallic fuel, additives and etc. Nowadays the size of energetic particles is attended because of their functional profits. Size reduction is well known way to increasing reactivity of additives in propellant formulations. Nanoparicles have considerable effects on composite solid propellants propert...
PURPOSE To demonstrate the value of poison control data as an adjunct to national drug abuse surveys and a source of data to inform and focus prevention efforts. METHODS National Poison Data System (NPDS) data are collected and compiled in real time by the 60 US poison centers as callers seek guidance for poison exposures. Demographic, geographic, product, outcome, and treatment-site data for...
Nitrate ester plasticized polyether (NEPE) is a new generation of composite solid propellants which its high energy content in comparing with conventional formulations, has attracted many researchers in the defense departments, all over the world. First of all an introduction and history and importance of NEPE propellants will be discussed and formulation and combination of propellants componen...
