提出一个可用于分析轴流压缩系统通过附加扰动主动抑制旋转失速的理论模型,利用该模型讨论了系统参数对抑制效果的影响及旋转失速和喘振之间的关系.结果表明该方法的抑制效果随着B参数及压气机级数、级负载的增加而降低;同一压缩系统发生一维喘振的工作点轴向速度系数由B参数及压气机轴对称特性共同决定,与特性线斜率无关;并且只有当喘振由旋转失速引起时,才可以通过抑制旋转失速来防止喘振的发生.
A theoretical model that can be used to analyze the suppression of rotational stall in an axial compression system by additional perturbation is proposed. The effect of system parameters on the suppression effect and the relationship between rotational stall and surge are discussed. The results show that the suppression effect Which decreases with the increase of B parameter and compressor stage and stage load. The axial velocity coefficient of the operating point where one-dimensional surge occurs in the same compression system is determined by the B parameters and axial symmetry characteristics of the compressor, regardless of the slope of the characteristic line. And surge occurrence can be prevented only by suppressing rotational stall when surge is caused by rotational stall.
