摘　　要：本文以某小型大涵道比涡扇发动机静子叶片为研究对象,采用数值模拟的方法探究不同结构的悬臂静叶对静叶流场以及流动损失。研究结果表明:前掠结构会增加泄漏流与流道内其余低能流体发生掺混的可能性,但不会降低悬臂静叶的总压损失。后掠结构和弯造型对于悬臂静叶的气动性能无明显优化作用。In this paper,a small turbofan engine with a large bypass ratio is taken as the research object,and the numerical simulation method is used to explore the flow field and flow loss of cantilevered vanes with different structures.The research results show that the forward-swept structure increases the possibility of mixing the leakage flow with other low-energy fluids in the flow channel,but does not reduce the total pressure loss of the cantilever vanes.The swept structure and curved shape have no obvious optimization effect on the aerodynamic performance of the cantilever vane.

关 键 词：悬臂静子叶片 泄漏流 叶型结构
