摘要

研究对象和目的。本文讨论了三种不同用途的快速单体排水量船模型和一种快速客运双体船模型。研究的目的是通过实验验证横截器在降低拖曳阻力方面的有效性。主题和方法。该研究基于Krylov国家研究中心深水拖曳罐的测试结果。主要的结果。该研究在四种模型上进行,并显示了它们的拖曳阻力如何取决于拦截器的推进和静态纵倾角。结论。试验证实了横突拦截器对运行速度对应弗劳德数0,4 - 0,6的快速排水量单体船和双体船的拖曳阻力降低效果。横截器减少拖曳阻力4,5 - 6,5 %。

Transom interceptor for towing resistance reduction of fast displacement ships
Object and purpose of research. This paper discusses three models of fast monohull displacement ships of various purpose and one model of fast passenger catamaran. The purpose of the study was to experimentally verify the efficiency of transom interceptor in towing resistance reduction. Subject matter and methods. The study was based on the test results available with Krylov State Research Centre Deepwater Towing Tank. Main results. This study was performed on four models and showed how their towing resistance depended on interceptor advance and static trim angle. Conclusion. The tests have confirmed the efficiency of transom interceptor in towing resistance reduction of fast displacement monohulls and catamarans with operational speeds corresponding to Froude numbers 0,4–0,6. Transom interceptor reduces towing resistance by 4,5–6,5 %.
