摘要

针对某包含引射、亚燃两模态(马赫数为0~4.0)的支板式火箭基组合循环(rocket based combined cycle)发动机地面集成试验

设计了样机用带支板的二元进气道.数值模拟对比分析了在亚燃模态下进气道加入支板前后的性能以及流道内的流动情况

验证了设计的合理性

并且给出了支板位置以及构型的改变引起RBCC发动机进气道性能变化的规律和优化设计结果.

Abstract

The inlet of RBCC(rocket based combined cycle) engine ground-test prototype operated in rocket ejector mode and ramjet mode(Mach number from 0 to 4.0) was investigated.The 2-D(two-dimentional) inlet with strut was designed.Through numerical simulation

a comparative analysis of the performance and the inner flow with/without strut in the inlet in ramjet mode was made

whereas rationality of the design was verified and a rule was derived for the variation of the performance of RBCC prototype's inlet

which was induced by the change of the location or the configuration of strut.Finally

an optimized configuration was obtained.
