摘　　要：依据模块化建模思想,建立了某新型上面级发动机系统起动过程的数学模型,并编写软件对起动过程进行了仿真计算。计算结果表明这种模块化的建模仿真方法易操作,软件通用性强,仿真结果与试验结果相符,并计算分析了入口参数变化对发动机起动过程的影响。Based on the idea of modularized design, the dynamic mathematics model of start-up process in a new upper-stage LRE was established. The simulation blocks of the LRE components and parts based on Matlab were constructed, the software was written and start-up process of the LRE was simulated. The results show that the simulation method is effective, the software can be extended to other LRE, simulation results are near to the test results, and effect of inlet parameters for the start-up process were studied and useful for LRE study.
