The object of the research is numerical simulation algorithms to determine the parameters of aero, thermo-, gas-dynamics processes, and dynamic loads that accompany the operation of rocket and space technology facilities (RSTF). The purpose of the work is to adapt and finalize algorithms for the numerical simulation of thermal, gas dynamics, and hydraulic processes, aerodynamics and thermal, and dynamic loads in various RSTF systems. Research methods – calculation methods of computational gas dynamics, hydraulics, and dynamics. Algorithms for numerical simulation of thermo-, gas-dynamic and hydraulic processes, aerodynamic, thermal, and dynamic loads in RSTF systems have been adapted and refined for: supersonic aerodynamics of launch vehicles (LV) in the presence of ramjet engine, body elements that can deviate, suspension wings, a twist of the body around its own axis; hydraulic and thermo-, gas-dynamic processes in control jet engines systems of low-thrust LVs and spacecraft with traditional and promising types of "green" fuel; calculation of the influence of jet streams from control engines (CE) on the gas-dynamic parameters around the spacecraft and determination of aerodynamic loads from CE combustion products on the spacecraft and its elements; determination of dynamic loads on marching stages of LV with active control systems on active sections of the flight path, taking into account dynamic and aerodynamic disturbances. For each of the four research directions, numerical simulation algorithms to solve the problems that were selected and formulated in the first work phase, have been adapted and refined. The results obtained in the second work phase will be used in research in the rocket and space industry.
