Objective is - to study characteristics of high-energy products obtained with the specified physical and chemical parameters as a result of advanced chemical processing of solid rocket fuel to produce elements of non-electric system of the initiation of explosives and optical detonators. Research methods. Energy-saturated products were used; the products were obtained while utilizing solid rocket fuel of intercontinental ballistic rockets PC-22 and some ammunition supplies: Octogen, ammonium or potassium perchlorate, hexogen extracted from the ammunition supplies. Differential and thermal gravitational analyses have made it possible to study all the products aimed at producing elements of non-electric initiation system and emulsion explosives. The Voodmate device was used to determine detonation velocity of the explosive charges. Results. Conditions of safe handling of solid rocket fuel of intercontinental ballistic rockets after its long-time storage have been analyzed. Solid fuel was extracted in terms of the specially developed laboratory and testing complex. Physical, chemical, and explosive properties of the samples of both solid rocket fuel and high-energy components, obtained as a result of advanced chemical fuel processing, have been studied. Ammonium perchlorate, potassiumperchlorate, and Octogen extracted from the rocket fuel were analyzed for their sensitivity to impact, friction, electrostatic discharge, detonation impulse, vibration loads, and action of fulminating detonator; they were also studies for chemical and thermal resistance as well as TNT equivalent. Scientific novelty. It has been determined that transition of ammonium perchlorate from the polymer binder to water solution depends on the type and size of the solid fuel samples, time mode of the water medium effect upon the solid fuel, and temperature. The studies have resulted in the experimental dependences of ammonium perchlorate concentration upon the technique of solid fuel sample preparation, water temperature, and period of water action in terms of the fixed temperature. Dependences of threshold ignition of Octogen samples upon the energy and geometry features of laser monopulse have been specified. Practical implications. A technology has been developed, and manufacturing has been organized to recycle solid rocket fuel involving a complex of different stage and including hydromechanical fuel extraction from the engine case, mechanical grinding of the obtained product, advanced chemical processing of the fuel with the extraction of oxidizers and high-energy components which are not produced in Ukraine.References
