中文摘要：
通过对多种落后角模型进行研究对比,选出其中一组,并对设计状态落后角模型重新修正,在此基础上结合S1流场计算发展了一种适用于轴流压气机落后角预测的模型.另对非设计状态落后角计算采用了修正模型.结果表明：建立的计算程序在一定的攻角范围内,对S1流场的预测结果是比较准确的,通过多组平面叶栅验证,在叶型弯角较大或者较小时,设计状态落后角模型预测精度均提高,误差范围控制在1°以内;建立的轴流压气机落后角预测模型,对多组轴流压气机设计状态落后角预测,误差都不超过2°,初步验证了模型的有效性.
英文摘要：
A set of models were selected after studying a series of deviation angle models, and the design deviation angle model was for axial-flow compressor was developed by co dition, an off-design deviation angle model wa calculating $1 flow field is accurate in a certain a series of cascades, the prediction accuracy re m .s vised. On this basis, a deviation bining the calculation of S1 flow used. The results show that the angle model field. In adprogram for incidence angle range. Through verification of of the design deviation angle models is improved, and the error is reduced to 1° no matter the blade profile camber is big or small. The prediction model of axial-flow compressor＇s design deviation angle is applied to a series of ax- ial-flow compressors, and the error is reduced to 2°. This means that the model is effective.
