大型船舶空气尾流场对飞机海上降落安全有重要的影响，研究空气尾流场特性对保障飞机安全、大型船舶海上活动有重要的意义。本文分别从数值模拟和实验2种角度综合分析大型船舶空气尾流场特性。研究中根据实际情况将甲板风风向风速差异分为9种工况条件，结果表明：甲板风风向角为−7°时空气尾流场气流扰动相对最弱，对飞机海上降落影响最小；上层建筑后部气流扰动对空气尾流场有明显的影响，而这是以往研究中忽略的因素。研究发现飞机海上降落所经过的下滑道气流场中存在气流转换区和下沉气流显著区，是飞机海上安全降落及空气尾流场防治中需重点关注的区域。
Aircraft carrier airwake effects the safety of aircraft landing, it is very meaningful for aircraft landing safety and aircraft carrier activity. CFD and experiment are choose for research of airwake character of aircraft carrier. Furthermore, wind direction angles and velocity of deck wind is divide for 9 working conditions according to actual situation. The conclusions is at list: airflow disturbance is relative weak in the –7° direction that wind of deck, it's affection is minimum for aircraft landing; air flow perturbation after ship island effect airwake obviously, it is also a neglectful factor; there exit the converted flow region and vertical maximum sink flow region on the glide slopes, the two regions are important regions for aircraft maritime security landing and research of airwake's prophylaxis and treatment.
