Abstract

The propellants in a liquid fuel rocket engine are guided into the combustion chamber by means of a back pressure provided by a pressurizing system. There are two common ways to optimize the mass of a pressurizing system, namely minimizing the pressure of the system and cutting off the inlet gas flow to the PROPELLANT TANK at the right moment. In the former, the minimum pressure required by the propellant pumps depends on accurate calculation of the inlet pressure of the pumps. In the later however, the cut-off time of the gas flow to the PROPELLANT TANK is a function of the rocket acceleration. The above parameters have direct impact on the total mass of the pressurizing system. In this work, the system pressure minimization and the inlet gas flow cut-off have been analytically studied. Our results have been compared to the existing experimental data, showing relatively close agreements.
