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

摘要： 研究了转子耦合对高、低压转子稳定性的影响。采用一种新的快速收敛方法 ,利用畸变传递修正系数 ,通过调整压比来满足各子压气机出口静压相等的条件 ,对耦合的影响进行了定量计算。结果表明 ,在估算发动机喘振部件时 ,高、低压转子间耦合的影响也是应该考虑的重要因素
