摘要/Abstract

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

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
