- 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.
