| Abstract: |
| The effect of spool coupling on compressor stability was analyzed A quickly convergent method was selected to calculate amplitude of the total pressure distortion at exit of low pressure spool in case of no coupling, complete coupling , and real coupling respectively , then the correcting coefficient of distortion transfer is calculated The results show that the spool coupling was important factor during evaluating engine surge component |
| Key words: Aircraft engine Rotor Coupling Distortion Stability |
