- 火箭基组合循环（简称RBCC）发动机性能分析模型的研究对于RBCC发动机结构的优化设计具有重要意义。本文结合RBCC发动机的结构特点和工作原理建立了RBCC发动机性能分析模型，并对RBCC发动机性能计算方法进行了研究。结合RBCC发动机引射模态和亚燃冲压模态的工作特点，通过迭代计算使进气道、混合段、燃烧室之间的参数耦合，实现了对RBCC发动机引射模态与亚燃冲压模态性能的快速分析。文章通过算例验证了算法的可行性，并通过与文献结果的对比验证了计算结果的可信度。
- Abstract:
- The study about the performance analysis model of rocket based combined cycle (RBCC) engine has important implication for optimization design of its structure. A performance analysis model for RBCC engine is built according to the structure characteristics and operating principle of RBCC engine. The performance computing method for RBCC engine is analyzed. In combination with the operating features of the ejector modal and sub-combustion ramjet modal of RBCC engine, the parameters of air inlet, mixing region and combustor was coupled by means of the iterative algorithm, and rapid analysis for the performance of the ejector modal and sub-combustion ramjet modal of RBCC engine was realized. Examples are used to demonstrate the feasibility of the method, and the credibility of the calculation results is verified by contrast with literatures.
