摘要
从掌控风扇/轴流压气机裕度方法回顾入手,探析美国和俄罗斯裕度控制方法及相应特点,提出将掠因素全面包含入二维特性预估循环,并将对裕度控制机制的朴素认识嵌入CFD结果判读,形成裕度定制方法。
On basis of reviewing on methods of achieving the goal of stall margin in design process of fan or axial compressors,stall margin customizing(SMC)is put forward.It is divided into two design loops.One is two dimensional,which includes through flow design and blade making and through flow performance prediction.Here through flow performance prediction plays most important roles in achieving the stall margin goal,and its most distinct feature is that the sweep effect has been completely involved.Another loop of controlling stall margin is three dimensional,in which performance prediction with three dimensional CFD tools is highly relied on.The present stall margin customizing emphasizes the former two dimensional loop because it is somewhat beforehand.This is the reason that the technique of'SMC'comes from.
