当动叶转角增加以进一步提升亚声速轴流压气机级负荷时,为解决其内部流动问题,提出了基于轴向速度提升的亚声速低反动度轴流压气机气动设计原理.分析了在该气动设计原理指导下,各气动参数间的相互影响,设计了一个验证级.三维黏性数值模拟结果表明:在叶尖切线速度为213m/s的前提下,实现了级压比为1.5,效率为92.5%的压气机级设计. When the rotor angle is increased to further enhance the subsonic axial-flow compressor load, the aerodynamic design principle of the subsonic low-reverse-flow axial-flow compressor based on the axial speed increase is proposed to solve the internal flow problem. Under the guidance of the principle of pneumatic design, the interaction between each of the pneumatic parameters is designed and a verification level is designed.The numerical simulation results of the three-dimensional viscous numerical results show that under the premise of the tip tangential speed of 213m / s, 92.5% compressor design.
