In order to investigate the effect of ship airwake on helicopter trimmed controls, a method of combining numerical simulation and helicopter flight dynamics model was adopted. The ship airwake was obtained by computational fluid dynamics (CFD) numerical simulation method, and the characteristics of ship airwake under active control were explored; at the same time, considering the effect of ship airwake on helicopter, the flight dynamics model coupled with the ship airwake was established. The results of relative hovering trim with/without airwake were calculated, and the effect of active control on helicopter trimmed controls was further compared and analyzed. The results showed that the ship airwake had a significant impact on the helicopter take-off and landing, compared with the interference of the ship airwake on the helicopter controls when there was no control, the addition of the blowing device can effectively suppress the downwash of the ship airwake, reduce the required collective pitch control by 7.8% and pedal control by 7.5%, improve other corresponding controls and alleviate the pilot control load.
