| 摘 要： | 运用Wassell法建立了某型涡扇发动机压气机特性的雷诺数修正数学模型,同时考虑雷诺数对涡轮特性的修正,计算分析了雷诺数对压气机特性、高低压转子共同工作点以及压气机喘振裕度的影响。结果表明,采用这种雷诺数修正模型可以用于定量评估雷诺数对发动机稳定性的影响。

| Abstract: | A mathematic model of Reynolds number correcting the performance of turbofan engine compressor was established with Wassell method.Based on the model in which the correction of Reynolds number to the turbo performance was taken into consideration,the effects of Reynolds number on the performance of compressors,on the co work point of engine,and on the surge margin were computed and analyzed.This correction model was proved to be valuable to evaluate the effects of Reynolds number quantificationally when assessing the engine stability. |
