| 摘 要： | 回顾了跨声速风扇/压气机转子气动负荷的研究历程,并对基准风扇转子和两个方案转子进行了三维流场分析。通过对195个研究方案的对比研究,目前阶段数值模拟的结果中风扇转子气动负荷系数达到0.65。在来流条件相同的情况下:合理组织激波结构可以大幅提高叶尖气动负荷;叶根大转角设计是提高根区气动负荷的可行途径;静子跨声速来流是高气动负荷跨声速风扇/压气机的必然结果。

| Abstract: | The process of investigation into transonic fan/compressor rotors aerodynamic load is reviewed,and the 3D flow field of the baseline rotor and two new rotor projects are researched.The aerodynamic load coefficient of transonic fan rotor has reached 0.65,as obtained through comparison research on 195 projects which aim at improving the transonic fan rotor aerodynamic load.The results show that in the same inlet flow condition,higher aerodynamic load near shroud can be achieved by organizing the shock wave,hi... |
