Counter rotating fans

Hi all,

Are there any pros and cons between the the use of 1 counter-rotating/ 1 standard rotating fan vs. using 2 standard rotating fans in twin powered jets? Will there be increase in performance?

Thanks.

Unlike props, The torque effect is very minimal with same performance, you don't get a swirl effect as the stators cancel that out. The cost to make a counter rotating rotor and projected sales is not worth the investment.
