Passive and active flow controls were used to reduce the turbulence intensity of ship airwake, but there was a recirculation zone on the deck resulting in intensively unsteady airloads of a helicopter. Thus, a novel active control deck (ACD) which can be automatically lifted up and descended is firstly proposed to weaken the recirculation. Helicopter airloads are examined by combining a viscous vortex particle approach with the lattice Boltzmann approach (LBM) via a one-way coupling model. This establishes a flow field analysis method of the ship with ACD. The accuracy of the method is validated by comparing the present prediction with the SFS2 experiment, detached eddy simulation (DES), and large eddy simulation (LES) results. The influences of the ACD on the ship flow field and airloads of a helicopter approaching the ship are analyzed. It is demonstrated that the ACD clearly suppresses the recirculation bubble when compared to the baseline SFS2. Additionally, the reduction of the rotor thrust, rolling, and pitching moments is weakened, with the largest reductions being 21.6%, 55.1%, 74.6%.
