摘　　要：航空发动机高压压气机采用可调静子叶片,可改善高压压气机的工作特性,扩大喘振边界,保证发动机稳定工作;通过优化可调叶片角度控制规律,还能提高发动机性能。基于双转子涡扇发动机的试车数据,介绍了可调叶片角度的控制方法,研究了可调叶片角度在低转速和高转速时的控制规律,分析了打开可调静子叶片角度对发动机性能的影响。研究表明,高压转子转速较高时,通过调节可调静子叶片角度,可以降低高压转子的物理转速,增加转子转速裕度,降低机械负荷,增加发动机在翼使用时间。Variable stator vanes（VSV） are used in aero-engine to improve the characteristics and expandthe surge margin of high pressure compressor to ensure stable working of aero-engine. The engine perfor-mance would be advanced by optimizing the angle control law of variable stator vane. Based on the test dataof dual-rotor turbofan engine, the angle control method of variable stator vane was introduced, the anglecontrol law of variable stator vane at low and high rotation speed was investigated, and the effect of openingthe angle of variable stator vane on the engine performance was analyzed. The results show that through theimprovement of the angle of the variable stator vanes at higher high pressure rotor speed, high pressure rotorphysical speed and mechanical load could be reduced, rotor rotation speed margin and time on wing of en-gine could be increased.
