The airwake behaviour around a ship provides useful information for the safe operation of helicopters on naval ships as well as in helicopter pilot training. This study investigates the impact of ship motions on the airwake behind the superstructure of a naval ship using Detached Eddy Simulation. A full-scale simplified frigate geometry is analysed stationary and in head waves at three different wavelengths under a uniform wind field and in the presence of an atmospheric boundary layer. The results reveal that an atmospheric boundary layer impacts significantly the airwake, as well as the vertical wave-induced motions of the ship, which reduce in amplitude by between 20.9% and 22.39% in heave, and up to approximately 38% in pitch. Moreover, the results show that the presence of an atmospheric boundary layer impacts the ship's heave and pitch motion periods. The flow field is also significantly altered depending on the ambient wavelength and period of motion, particularly in the case where an atmospheric boundary layer is modelled.

船舶周围的空中苏醒行为为海军直升机在海军舰艇上的安全操作以及直升机飞行员培训提供了有用的信息。本研究使用分离涡模拟研究了船舶运动对海军舰船上部结构后的空中尾迹的影响。在均匀的风场和存在大气边界层的情况下，在三种不同波长的固定波和头波中分析了一个完整的简化护卫舰几何形状。结果表明，大气边界层会显着影响飞机的尾流以及垂直波引起的运动，从而使升沉幅度降低20.9％至22.39％，俯仰幅度降低约38％。此外，结果表明，大气边界层的存在会影响船舶的 升沉和俯仰运动周期。流场也根据环境波长和运动周期而显着改变，特别是在模拟大气边界层的情况下。
