Abstract: The multi-stage axial compressor performance was measured using a streamline curvature method based on two-dimension(axisymmetric) mathematical model.The influence of various factors on the deviation angle and loss was represented by components.After being verified through a number of experiment data,this method offers an extremely high accuracy.By comparing the calculated results and test data for a multi-stage axial compressor,this method demonstrates that it could assist in predicting the characteristics of multi-stage axial compressor and spanwise parameter distribution under off-design working conditions.
