这项研究是一个长期项目的一部分，该项目旨在绘制模型船的尾流图，以缩放到全尺寸并在模拟器中使用，以提供接口测试的替代方案。使用氦气泡、烟雾、摄影和视频设备对静止模式下 DD-963 飞行甲板附近的气流进行了详细研究。结果表明，尾流中的主要变量是船舶的偏航角，俯仰角和横滚角影响较小。在飞行甲板上观察到一些高度复杂的流动模式。例如，在零偏航时，气流沿船舶中心线流过机库并分裂：较高层的气流继续向船尾延伸，较低层的气流向下流向甲板，然后返回机库；这股气流进一步分流，流向左舷和右舷，向上卷曲，几乎达到机库“屋顶”的高度，最后沿着靠近船两侧的路径顺风流动。根据偏航角，该图案会移位到船舶的一侧或另一侧。当相对风位于右舷时，飞行甲板上的湍流总体水平较高。
This study is part of a longer-term project to map the airwakes of model ships for scaling to full size and use in simulators to provide an alternative to interface testing. A detailed study has been made of the airflow near the flight deck of the DD-963 in a stationary mode using helium bubble, smoke, photographic and video equipment. The results show that the primary variable in the airwake is the yaw angle of the ship, pitch and roll having a lesser influence. Some highly complex flow patterns have been observed on the flight deck. For example, at zero yaw the airflow along the centre line of the ship flows over the hangar and splits: the higher level of the flow continues aft and the lower level proceeds downwards towards the deck and turns back towards the hangar; this flow further splits, heading towards port and starboard, curls upward almost to the hangar "roof" level and finally flows downwind in two streams along paths close to both sides of the ship. This pattern becomes displaced to one side of the ship or other, depending on the yaw angle. The general level of turbulence on the flight deck is higher when the relative wind is on the starboard side.
