Effects of specific swirl distortion on performance of transonic compressor

  • 摘要: 为研究S弯进气道出口和翼身融合体(HWB)飞机发动机进口两种特定涡旋流对压气机气动性能和稳定性的影响,将设计的新型叶片式旋流畸变发生器与跨声速压气机Stage 67进行联合数值仿真,获得进口旋流条件下的压气机特性线和流场分布,并与转子进口为均匀来流时进行对比分析。结果表明:在100%换算转速,S弯进气道产生的旋流使得压气机压比和效率在近峰值效率点分别下降0.06%、0.85%,稳定工作流量范围减小5.97%,压气机稳定裕度降低1.13%,压比和效率特性线均向左下方移动。HWB飞机产生的旋流使得压气机在近峰值效率点的压比增大6.61%,效率下降6.25%,稳定工作流量范围减小26.88%,压气机稳定裕度降低2.84%,压比特性线向右上方移动,效率特性线向右下方移动。
