A guide vane for the sectorial cascade experiment was designed in order to simulate the outlet airflow parameters of the real compressor rotor blade (inlet airflow parameters of the real compressor stator blade). Three inlet guide vanes were designed according to a given exit flow angle distribution curve average of circumferential pitch along the relative blade height of the compressor rotor and the final design airfoil was obtained by gradually optimizing the three cases and comparing to target curve. Aerodynamic analysis of the design airfoil was carried out by numerical simulation. Results show that the flow field at the design guide vane outlet of the sectorial cascade is similar to that at the rotor outlet of the real compressor. In addition, the flow field of the guide vane and stator outlet with changing the Mach number of the guide vane inlet was studied in order to guide the sectorial cascade experiment.
