摘　　要：本文介绍了低反力度吸附式压气机的应用背景,并基于两种低反力度压气机设计理念初步设计了一台三级高负荷吸附式压气机。三维数值模拟结果显示,在叶尖切线速度为370m/s,整机通流效率不低于86%的条件下,多级吸附式压气机实现了6的总压比,进一步验证了低反力度设计理念在高负荷压气机设计中应用的可行性。通过详细分析设计点处一维、S2气动参数分布以及三维流场细节并兼顾抽吸方案的复杂程度,对初步设计方案进行总结分析,为进一步优化设计工作提供了参考依据。The application background of the low-reaction aspirated compressor is introduced in this paper firstly,and then a three-stage highly-loaded aspirated compressor is designed out preliminarily based on the two kinds of low-reaction concepts.3-D numerical simulation shows that,the multistage aspirated compressor could achieve a total pressure ratio of 6 at a tip speed of 370m/s with the through-flow efficiency beyond 86%,which further verifies the feasibility of application of low-reaction in the design of the highly-loaded compressor.By analyzing the 1-D total parameters,S2 parameters distribution,3-D flow details and considering the complexity of aspirated structures,the initiatory design is evaluated,which could provide the basis for the further optimization effort.
