摘　　要：基于多扇区平行压气机理论,对采用俄罗斯的可移动扰流板畸变试验的涡扇发动机,进行了气动稳定性及性能的数值模拟,结果表明畸变使得发动机稳定工作裕度降低、推力下降、耗油率增加。A distortion generator with a moveable sliding board generates a distorted flow field. The inlet total pressure distortion tests are completed on a dual - spool turbofan engine. Based on multiple segment parallel compressor model, the numerical simulation of the aerodynamic stability and performance of turbofan engine are conducted. The results show that the distortion makes the steady operation range of the turbofan reduce, the engine's thrust decrease, and the specific fuel consumption increase.
