摘　　要：通过模块化设计 ,仿真分级燃烧循环发动机的动态过程。通过发动机工作参数的波动特性分析 ,为实际的发动机研制提供参照和依据。The dynamic process in the staged combustion cycle liquid rocket engine was simulated through the module codified.Owing to the mathematical model form mulated that took account of the inertia,viscosity and compressibility of the liquid flow at the same time,this method could generally express the distributed characteristic of the dynamic process in the supplying system.What is more,in order to obtain higher precision in simulation calculation,we also made use of the experimental results to adjust parameter values of some important characteristics.Finally based on the simulated data,the fluctuations of the engine working parameters were discussed in this paper.And with the analysis results we provide some comparisons and basis for designing the staged combustion liquid rocket engine in the future.
