With further understanding of the internal flow details in the low reaction and aspiration axial compressor stages

the design method of low reaction and aspiration axial compressor used in the three stages was further improved. A verification aerodynamic design of a low reaction and aspiration axial compressor with three stages was carried out. From these three-dimensional viscous numerical results

a compressor was attained with total pressure ratio 6.1 and efficiency 88.1%

without consideration of the influence of the bleed flow at inlet tip tangential speed 370m/s. Boundary layer suction was used only in the first and third stator. The total bleed flow was around 11.3% of the inlet.
