  • In order to study the effect of bowed stator blade on stability enhancement by tip injection, the experimental research on a low-speed axial flow compressor was carried out. The effect of stability enhancement by tip injection and the compressor internal flow field information were comparative analyzed when the first stage stator blades were bowed and straight stator blades. Results show that,the first stage straight stator blades replaced by bowed blades, the effect of stability enhancement by tip injection is more significant, this is because in the process of compressor stall, the modal wave mainly concentrates in the tip region, and the tip injection can broaden stable working range of the compressor by improving the flow field in the tip region.
