槽道水翼滑行艇快速性能研究

本文论述槽道水翼滑行艇的基本原理、快速性能及其及化规律。通过模型试验、中间艇试验和实部的航行试验，证实了槽道水翼以及与尾压板的联合作用，使槽道型滑行般的阻力减小，航行姿态得到调整和改善，艇的超载能力等综合航海性能有明显的提高。模型试验结果表明槽道水翼使艇体总阻力平均减小25％左右；中间试验艇的航速提高了8％；实船试航航速提高了18％；负荷超载能力增加15％。通过对试验结果的分析，给出对设计有参考意义的结论。

A STUDY ON PERFORMANCE OF CHANNEL-HYDROFOIL-TYPE PLANING BOATS

The present studyalms to improve the performance of planing boats by adopting the design concept of equivalent deep-Vee ship forms with channel hydrofoils and stransom flaps. The model experimental results show that a set of well- designed channel hydrofoils may reduce the total planing resistance about 25%. The middeling ship trial results show that channel hydrofoils may increase ship speed above 8%. And the ship sea trial results show that channel hydrofoils may increase ship speed above 18%, extra-load capability 15%.
