An active control technique using blowing method at the tail of aircraft carrier is presented to mitigate the effect of cock wake caused by deck wind on carrier-based aircraft. Computational fluid dynamics is used to calculate the characteristics of the CVN-73 carrier wake field. When the deck wind angle is zero, a comparative study is carried out under working conditions with and without active control technology, respectively, and the effect of blowing angle on the flow field is also analyzed. The result shows that with the increase of blowing angle, the inhibition effect of control technology on downwash in the wake field increases first and then decreases. When the blowing angle is 30 or 45 degrees, the inhibition effect is the most obvious, and the maximum downwash speed can be reduced to half. In conclusion, the active control technique using blowing method can improve the cock wake environment and increase landing safety of carrier-based aircraft.
