摘要
长江下游(通申线)综合节能客轮“新越”号,系我所于80年代后期设计。该船的船宽吃水比为5.25,属于超浅吃水船,设计难度较大。作者采用多种方案,进行了大量的水动力试验研究,主要是线型的优化研究,经分析比较,最后采用我所开发的不对称双尾鳍船型,解决了推进、操纵、布置等一系列问题,达到了较高的快速性和节能指标。该船与70年代的优秀船型——双桨轴支架型客轮相比,船体节能效果达到25％,综合节能效果为35％。
The complex energy—saving passenger ship 'XINYUE' operating at the lower reaches of the Changjiang River (Nantong/Shanghai course)was designed by SSSRI in the late 80's. The breadth—draft ratio of this ship is 5.25, an utral—shallow—draft rather difficult to design. A large number of hydrodynamic tests were carried out to seek an optimum shipline from various schemes. At last, the unsymmetric dual stern fins developed by SSSRI was adopted through analysis and comparison, which solved the problems of propulsion, maneuver and layout so that to produce the ship with higher speedability and energy—saving index. Compared with the passenger ship with dual propeller shaft brackets——an outstanding shiptype of the 70's, the ship can have an energy saving of 25% from hull and a total energy saving of 35%.
