The research goal is to develop research support, methods and means of investigations of the main regularities of gas plasma dynamical processes and interactions between materials and elements of engineering systems with high-enthalpy gas flows and the plasma under energetically extreme conditions. Methods used: information and analytical method, theoretical method, systems analysis, numerical simulation, physical modeling, physical experiments. Research support, methods and means of investigations of the main regularities of gas plasma dynamical processes and interaction between materials and elements of engineering systems with high-enthalpy gas flows and the plasma under energetically extreme conditions are developed. The novelty of the research results: numerical estimations of the effects of geometric parameters of compressor stages on power characteristics of stages are obtained; visualization patterns of the flow through channels of models of sound suppressors in a pulse regime are obtained using a polarization interferometer; ways of extending the efficiency of the process control in a combustion chamber of a rocket –space engine are found, based on radiometric diagnosis of thermogasdynamical characteristics of the process; dependencies of gas dynamical characteristics of the flow on a molecular mass of an injected mixture and its ignition are derived; a synergetic effect of influence of atomic oxygen and vacuum ultraviolet at a height of 700 km resulting to increase in ablation of polyimide films ( structural spacecraft materials) several times is revealed a scientific and methodical base for developing the industrial equipment and related technologies for protective, tribotechnical and other functional coating with a help of magnetron ion-plasma plants is created; choosing the main indices of no-failure operation, maintainability and keeping quality of engineering systems is justified; essential effects of spacecraft orientation on the value of space debris particle flows at its surface and the probability of collision with them are presented.
