探究了局部端前掠对跨音悬臂静子气动性能的影响。一方面,局部端前掠可以减小悬臂静子轮毂端吸力面上跨音区的峰值马赫数,减小激波损失;另一方面,局部端前掠可以减小悬臂静子轮毂端的峰值负荷,使得负荷沿弦长方向重新分布,减小泄漏损失。同时,把局部端前掠技术应用于一台工业用多级轴流压气机中的跨音悬臂静子,在保持总压比和稳定工作范围的前提下使得多级压气机绝热效率提高近0.85%。 The effect of local front sweep on the aerodynamic performance of transonic cantilever stator was investigated. On the one hand, local pre-sweeping can reduce the peak Mach number of transonic region on the suction side of the cantilever stator hub and reduce the shock loss; on the other hand, local pre-sweeping can reduce the peak load on the cantilever stator hub end, Redistribution along the chord direction to reduce the leakage loss. At the same time, the local end-sweep technology is applied to a transonic cantilever stator in an industrial multi-stage axial compressor, which improves the adiabatic efficiency of the multi-stage compressor by nearly 0.85% while maintaining the total pressure ratio and the stable working range. .
