摘　　要：为了探究海平面静态一次火箭沿流道放置位置对RBCC性能的影响,文中开展了进气道/燃烧室一体化全流道的数值模拟工作。结果表明:海平面静态,一次火箭沿流道后移对进气系统的影响比较复杂,且与一次火箭流量的大小高度相关,而对RBCC推力和比冲的影响则一直比较积极;海平面静态,当需要一次火箭大流量工作时,建议其位置应尽可能沿流道后移,以保证RBCC的整体性能最优。Influence of primary rocket location along the flow-patch on the performance of RBCC at sea-level static was researched by CFD on an inlet-combustor combined RBCC structure. It is concluded that the influence of moving primary rocket along the flow-patch backward on intake performance is very complicated and closely bound up with the mass flow rate of primary rocket. However, moving primary rocket backward has always positive influence on the RBCC thrust and specific imptilse. Moving primary rocket as backward as possible at sea- level static is recommended to maintain optimal performance of the RBCC engine.
