| 摘 要： | 利用Ａｄｋｉｎｓ－Ｓｍｉｔｈ二次流模型计算得到转子出口截面落后角沿叶高的变化。在压缩系统稳定性模型中考虑叶尖流面落后的角影响，并提出一个新的时滞参数计算公式，计算结果表明，落后角的大小对压缩系统的稳定性影响很大，同时揭示了叶尖间隙对压缩系统稳定性的影响。

| Abstract: | The spanwise deviation angle distribution at the trailing edge section of rotor blade wascalculated using the Adkins-Smith secondary flow model. A new formula concerning thetime-lag parameter was presented by incorporating the deviation angle in the blade tipstream-surface into the compression system model. The calculated results show that the deviation angle has an important effect on the compression system stability as well as the effectsof tip clearance of rotor blade. |
