本文提出了亚音速多级低反动度高负荷轴流压气机的设计概念,并对其可行性进行了理论分析。应用此设计概念,结合附面层抽吸技术,将某11级轴流压气机改为7级,并对具有典型流动特征的末两级进行了详细的数值模拟。数值模拟结果表明多级低反动度高负荷轴流压气机的设计概念是可行的。
In this paper, a subsonic multi-stage low-reaction highly loaded axial compressor design concept was proposed and its feasibility was verified by theoretical analysis. Applying this design concept, a certain 11 stages axial compressor was redesigned to 7 stages. The last two stages with typical flow patents were detailed studied by numerical simulation. The results show that the new design concept is feasible.
