ABSTRACT:
In an axial flow compressor, an apical angle at a leading edge of a stator blade progressively increases from a root end to a tip of the stator blade whereby the stator blade loss and noises caused by unsteady inter-blade airflow can be minimized. Preferably, the apical angle at the tip of the stator blade is 1.5 to 2.5 times of the apical angle at the root of the stator blade.
