S8  Engenharia Aeroespacial    Titulo: MATHEMATICAL MODELING AND ANALYSIS OF LIQUID PROPULSION SYSTEMS PROPELLANT TANK PRESSURIZATION   Resumo : ABSTRACT: PRESSURIZATION OF PROPELLANT TANK OF A SATELLITE LAUNCH VEHICLE INCLUDES SEVERAL AEROTHERMOCHEMICAL PROCESSES INSIDE THE TANK, BOTH IN GAS AND LIQUID PHASES. IN THIS WORK, A UNIVERSAL MATHEMATICAL MODEL FOR PROPELLANT TANK PRESSURIZATION WAS DEVELOPED FOR ANALYZING THE APPLICATION OF CHEMICAL NON-EQUILIBRIUM COMPOSITION OF COMBUSTION PRODUCTS AS THE PRESSURIZING GAS. IN THE NUMERICAL ANALYSIS, EFFECTS OF THE CHEMICAL REACTION, THE PRESSURIZING GAS INJECTION SCHEME AND THE PRESSURIZING GAS INJECTION VELOCITY ON PRESSURE AND AVERAGE TEMPERATURE WERE STUDIED. KEY WORDS: LIQUID PROPULSION, TANK PRESSURIZATION, PROPELLANT TANK, ROCKET ENGINE, COMBUSTION PRODUCT     Autores : Krioukov, Viktor G.
