The aerodynamic characteristics of counter rotating fan was effected by rotating speed ratio of first and second stages, appropriate speed ratio could improve aerodynamic characteristics of counter rotating fan. The influence of rotating speed variation of first and second stages on the aerodynamic characteristics of counter rotating fan was studied by numeral calculation and experiments. First, the influence of changes in rotating speed on powers and internal flow parameters was quantitatively analyzed by velocity triangle. Then, the results of calculation were compared with the results of experiment to analyze the performance of fan under the standard rotating speed. Finally, air flows in the fan were analyzed with the results of calculation. It is found that the flow parameters and performance of fan change more efficiently by changing the rotating speed of the first stage under the same rotating speed changing percentage of first and second stages when the conditions of inlet keep invariant. Combined with the performance of fan and the demand of reality, the most optimal rotating speed ratio is 1.1:1. The efficiency of counter rotating fan is 75% under this rotating speed ratio and transmission efficiency of 88.4%.
