| Abstract: | A research of modeling and simulation for the start-up process of expander cycle liquid propellant rocket engine (LPRE) is carried out in this paper. Based on the module modeling means, the expander cycle LPRE is disassembled into some typical components and their mathematical simulation models are researched. By utilizing the Simulink toolbox, various module libraries needed by the calculation of the transient process of LPRE system are programmed. The libraries lay a foundation for the continuative numerical simulation work. Then, the simulation investigation on the start-up process of the expander cycle LPRE is carried out and the influence factors in the start-up process are investigated. |
