Abstract: To explore the characteristic in the field of high transonic fans and accumulate the experience of design, in addition to measure the total pressure ratio and efficiency, the concerned parameters after stage of the tested fans were measured by use of the three-holes probe and the total pressure rake. Moreover, CFD was employed to research the match between rotors and stators on hubs. The experiment and calculation were discussed. Finally, the shortcomings were pointed out and the improvement suggestions were put forward.
