  • The flow of counter-rotating compressor was simulated by the NUMECA, and the flow structure and performance were obtained under different cambers of variable-camber inlet guide vanes (VIGVs). The total pressure ratio decreased and stability operating range became narrow when the camber of VIGV was positive. With the increasing camber of VIGVs, the total pressure ratio increased, and the point of blockage moved right-wards when the camber of VIGV was negative. The stability operating range was widest when the camber of VIGV was -15°. The results showed that it could adjust and improve the performance and flow structure of counter-rotating compressor by using VIGV. The reason is that the VIGVs could change incidence angle of rotors, and make incidence angle close to design incidence angle, thus improving the performance of compressor.
