舰岛对航母下滑道空气尾流场特征影响的实验研究

The experiment research of influence of ship island on airwake character of aircraft carrier glideslope approach

航母空气尾流场是威胁舰载机着舰安全的重要环境因素之一。该文着眼于舰载机着舰的实际需求,以美军标的"雄鸡尾流"模型为参考,采用实验方法,测量航母模型下滑道的空气尾流场,分析其规律特征以及舰岛的影响。在实验研究的过程中,提出航母空气尾流场实验测量的新方法,定义航母空气尾流场中作为次级分量的"舰岛空气尾流场"的概念。研究表明:在甲板风方向与下滑着舰跑道相平行时,实验测量结果整体上与"雄鸡尾流"模型趋势基本一致,证明该实验研究方法的有效性,以及舰岛在不同甲板风方向上的影响是不同的。上述研究结论可为航母空气尾流场的实验研究以及确立相应工程化模型等领域提供研究积累。

Aircraft carrier airwake is one of the most important factors to aircraft landing safety.Because of aircraft landing requirement,and Military Specification(MILSPEC),also named as'cock wake'is regard as reference,airwake of aircraft carrier glideslope approach was measured,the character of airwake and the effect of ship island were analysed.The new method of measuring aircraft carrier airwake is put forward,and the conception of'ship island airwake'as subscale airwake in the aircraft carrier airwake is defined.Consequence shows that the experiment result closed to MILSPEC,it proves that the experiment method is effective;At the same time,the effect of ship island is different in different wind over deck angels.All these valuable conclusions can supply aircraft carrier airwake experiment research and its engineering model etc.
