Abstract
The energy potential of ten fluorodinitromethyl-ONN-azoxy compounds as binder plasticizers in model composite solid propellants of various formulations, with and without metal (aluminum hydride or metallic aluminum). The energy potential of these plasticizers was compared with that of the most energy-intensive known plasticizers (nitroglycerin, tetranitromethane, and dinitrofurazan) for model solid propellants intended for different stages of rocket systems. It was shown that almost all of the studied fluorodinitromethyl-ONN-azoxyfurazans, when used as active binder components, provide higher energy values than nitroglycerin and tetranitromethane, and some fluorodinitromethyl-ONN-azoxyfurazans even outperform dinitrofurazan. High-performance quantum-chemical calculations of the enthalpy of formation of new, not yet synthesized energy-intensive substances that are promising in various fields of application were carried out.
