| 基于轴流压气机逐级过失速特性，建立了多级轴流压气机过失速瞬态，包括喘振或旋转失速的分析模型。发展了分析轴流压气机过失速响应的动态滞后方法，并确定了压气机过失速响应的统一时间滞后常数。对一实验轴流压气机的过失速瞬态进行了数值模拟，与实验结果的一致性较好。 |

| Abstract: |
| A stage-by-stage axial flow compression system model has been established which can predict axial flow compressor behavior during post-stall conditions such as surge and rotating stall. A first-order lagging method is used to simulate the compressor dynamic response during post-stall conditions, and a general time constant is determined. The predictions for a three stage axial flowcompressor are given. It is apparent that the numerical simulation with the model and the method gives results in good agreement with available experimental data.. |
