如今，拦截器已广泛应用于各种高速飞行器中。在这项研究中，揭示了在伊斯坦布尔技术大学的拖曳水箱中进行的拦截器熟练程度试验的结果。该模型通过具有六种不同部署深度的三个横向位置的拦截器进行了测试。对于三个位置，拦截器横向放置在船尾；靠近中国，在中间，靠近龙骨。第四枚拦截器全长13.00%LWL。结果表明，FN为0.58~1.19，减阻效益为1.50%~11.30%，配平角度为1.60~4.70°，减阻效果显著。此外，最重要的结论之一表明，对于相同的叶片展开高度，拦截器的作用从龙骨到中国递减，因此如果可行，至少应该从龙骨到中国区域三个部分分开控制叶片。
Nowadays interceptors have been widely used in a vast range of high-speed crafts. In this study, the results of interceptor adeptness experiments made in Istanbul Technical University's Towing Tank are unveiled. The model was tested through three transverse locations of interceptors with six different deployment depths. For three locations, the interceptor was positioned transverse on the aft; close to chine, in the middle and close to the keel. The fourth interceptor was a full length of 13.00% LWL. The results show a significant drag reduction in benefits of 1.50%–11.30% for Fn 0.58–1.19 and the trim reduction was observed in between 1.60 and 4.70°. Besides, one of the most significant conclusions indicates that the effect of the interceptor decreases from keel to chine for the same blade deployment heights so the blades should be controlled separately at least in three parts from keel to chine area, if operable.
