摘要：

In this paper, a new approach for simultaneous simulation of warm pressurization systems and an engine feed system is developed. The governing equations of the pressurization system are also derived. The simulation results of gas generator pressure, ullage pressure, and pressure at the inlet of the fuel and oxidizer pumps are compared with experimental results. This comparison reveals that the developed approach may successfully be used to determine the interaction effects of an engine feed system and an engine pressurization system. At present, the approach and results are limited to single stage to orbit liquid engines that use the gas generator gases for pressurization. (C) 2011 Elsevier Ltd. All rights reserved.
