水翼辅助推进船舶波浪中运动和增阻特性研究

基于在船首两侧增添（固定）水翼的水翼辅助推进船舶的设想，选取集装箱船型作为研究对象，采用三维面元法对原型和水翼船在规则波中的运动和增阻响应进行了预报，并与试验结果进行比较，验证了计算结果的准确性。研究结果表明水翼能够有效地减小船舶在波浪中的纵摇、垂荡和增阻响应，其中添加水翼船在波浪中的纵摇和垂荡响应峰值分别减少了21%和24%，而增阻响应则减小了80%。此外还对水翼展弦比和安装位置对船舶在波浪中的运动和增阻响应的影响进行了研究。

Study on motion and added resistance of a ship with hydrofoils assisting propulsion

In order to improve the propulsion and sea-keeping performance, a ship with fixed wave devouring hydrofoils mounted at the bow is proposed. The motion and wave added resistance in regular waves of a container ship with and without hydrofoils are investigated based on 3D panel method. Ship model test is also carried out to validate the accuracy of the calculation. The results show that the fixed wings contribute a lot to the improvement of the ship sea-keeping performance. The pitch, heave and added resistance in regular waves had been reduced 21%, 24% and 80% by the hydrofoils. The effects of aspect ratio and installation position of the hydrofoils to the ship motion and added resistance, are also investigated through 3D panel method.
