| 摘要: |
| 应用Ｓ２流面准三元计算程序，对两台典型小型发动机压气机（Ⅰ型机、Ⅱ型机）的气动性能进行了分析。更加真实地揭示了它们内部的流动情况，并分析了它们的改进思想和方法。其中Ⅰ型机是应用“平均设计”思想设计的早期跨音压气机，Ⅱ型机是其成功的改型机。 |

| Abstract: |
| In the this paper, Quasi-Three Dimensional calculation program of S2 stream surface is applied to analyze aerodynamic characteristics for two typical miniature transonic compressors of Aero-engines (model Ⅰ and model Ⅱ ). The internal flow situation and improvement methods are discussed. The authors expert to provide some thinking and illuminating remarks for improvement of this kind of compressors. |
