abstract

This paper presents the calculation of optimal restagger and test method for ten-stage subsonic axial flow compressor with four rows of variable stator. The test results show that both are in close agreement.

The test results show that the overall compressor performance with optimal restaggers was significantly improved in comparison with the original. The efficiency at mid-speed increased by 12.7%. Surge margin reaches 31.2%. The total range of operation for compressor was expanded by 34%.
