| 摘 要： | 给出了考虑压气机径向扰动对失速影响的轴流压气机三维气动稳定性模型。计算结果表明压气机的失速特性与压气机基元叶栅特性密切相关。在轴流压气机三维气动稳定性模型的基础上，给出了考虑轴流压气机三维效应的主动控制模型及其传递函数。并在阶跃输入情况下，对轴流压气机二维和三维主动控制模型的开环系统在频域进行了响应分析

| Abstract: | A new three-dimensional aerodynamic stability model for an axial flow compressor to study the effects of radial disturbance on the rotating stall is presented.The calculated results show that the stalling characteristics of the compressor is closely related with its cascade characteristics including total pressure rise versus the flow rate and inlet flow angle.Based on the 3D aerodynamic stability model,the related active control technique and the open-loop transfer function have been provided,in which the three dimensional flow effects are involved.The response analyses of the open loop systems for the 3D stability active control model with step impulse were conducted in different flow ranges. |
