THE ISSUES OF CHEMISTRY AND TECHNOLOGIES OF RESIN MIXTURES FABRICATION FOR INTERNAL HEAT-PROTECTIVE COATING OF ROCKET SOLID FUEL ENGINE

One of specific features of rocket engineering – is the high rate of sophistication and renewal of structures due to constantly growing operational and technical specifications imposed to them.  Every generation of rocket and space products features a new complex of design and processing parameters and new materials possessing higher properties. It is impossible to resolve the entire scope of design and processing tasks in course of development, creation and operation of spacecraft without extend development and infusion of new materials which possess a number of required characteristics imposed to state-of-the-art technology products. The most widespread and sophisticated structures of modern technology – are solid-propellant rocket motors (SPRM) made of polymer composite materials. One of the major tasks associated with their creation is development of the internal thermal protection coating of solid-propellant rocket motor casing. State enterprise Yuzhnoye Design Office named after M.K. Yangel is currently carrying out works on creation of solid-propellant rocket motors. Development of their internal thermal protection coatings using mainly domestically produced materials with specified requirements is a scientific and technological task of high importance which confirms the relevance of dissertational research.The article is devoted to the analysis of components and ingredients for rubber compounds, which provide the properties and basic functions of the thermal protective covering of solid propellant rocket engine. The article shows the main results of the work related to the development of prescribed composition and technology of manufacturing of elastomeric material which used in the manufacture of internal heat-resistant coating of solid-propellant rocket engines made of polymer composite materials.
