完成了冲压发动机推进系统的统一流分析，其理论模型以质量、动量、能量和物质浓度的完全守恒方程为基础，同时，考虑有限速率化学反应以及变量的各种性质。采用低雷诺数的Ｋ－ε两方程模型实现湍流门包。利用全耦合隐函数和上风总变差递减法的下一上限法求解空问离散化的控制方程。使用已知的基本变量（ρ＇，ｕ，ｖ，ｈ，Ｙｉ）而不用守恒变量。该算法可对含有激波不连续的宽广马赫数范围进行化学反应流研究。在求解过程中，为简化冲压发动机的复杂结构，采取带状分区算法。该数值方法对实际冲压发动机推进系统的内流分析提供了一种新方法。
The unified flow analysis of the ramjet propulsion system is completed. The theoretical model is based on the complete conservation equation of mass, momentum, energy and mass concentration. At the same time, the finite-rate chemical reaction and various properties of variables are considered. The turbulence gate package is realized by using K-ε two-equation model with low Reynolds number. Using the next upper bound method of the fully coupled implicit function and the upwind total variation diminution method, the governing equation of discretization of the space is solved. Use known basic variables (ρ ’, u, v, h, Yi) without conserving variables. The algorithm can study the chemical reaction flow for a wide range of Mach numbers with shock discontinuities. In the process of solving, in order to simplify the complex structure of ramjet engine, striping algorithm is adopted. The numerical method provides a new method for the inflow analysis of the actual ramjet propulsion system.
