| 摘 要： | 火箭冲压组合循环(RBCC)推进系统工作过程中,来自冲压管道的空气和火箭发动机的排气流进行混合,混合气体通过一个扩压器,在扩压器中与燃料混合并燃烧。本文基于CFD技术,研究了基准掺混段内的掺混过程,N-S方程的计算结果显示,在掺混段出口,截面气流并不均匀,这将会影响整个RBCC推进系统的性能。在此基础上,本文还研究了掺混段长度和掺混段出口静压对掺混性能的影响。

| Abstract: | Based on Computational Fluid Dynamic technology,the mixing process of Rocket Based Combined Cycle(RBCC) propulsion system is researched.The idea of RBCC propulsion system means to combine rocket engine and ramjet engine effectively,which can flight from sea level to high flight in wide Mach ranges.Considered from operating process,flows from ramjet and rocket mixed together in the mixing part,and the mixture flow through a diffuser,where the mixture mixed with fuel and burning. Two different parameters are ... |
