 The object of research is methodological support for numerical simulation of controlled gas flows; experimental research base. The aim of the work at the second stage is the development of methodological support for the numerical simulation of controlled gas flows; improvement of the experimental research base. Research methods are methods of system analysis, mathematical and physical simulation of processes in complex technical systems. The list of initial data for numerical simulation of processes in the nozzles of rocket engines with an adjustable thrust vector is substantiated. The possibility of constructing different profiles of physical quantities according to the laws necessary for solving problems is shown. Data selected according to the optimal principle improve the calculation process and the correctness of the results obtained. It is shown that the established dependencies can be used to determine the parameters of the working body when simulating the gas flow in the nozzles of rocket engines. Methodological support for solving complex problems of gas dynamics of supersonic nozzles has been developed. Test calculations of a shortened nozzle with a bell-shaped nozzle have been performed. The results of the calculations have been verified by the results of experimental studies carried out in the Institute of Scientific Research of the National Academy of Sciences of the National Academy of Sciences of the Russian Academy of Sciences and the Ukrainian Academy of Sciences. The results of work on the modernization (refining of stands) of the experimental base to ensure prospective research of processes in rocket engines and a gas-jet shredder of loose materials are given. A database has been developed that ensures the creation of a system of automatic control of a gas jet shredder to support a rational mode of grinding loose materials.
