可收缩式双尾襟翼帆设计及性能研究

A collapsible twin-tailed wing sail device

为了在保证船舶航行安全的前提下,促进船舶航运业充分利用海上清洁能源(风能),达到节能减排的目的。文中提出一种新型船舶助航风帆装置——可收缩式双尾襟翼风帆,其具有较传统风帆更自动、灵活的结构特点,即在有利风况下能伸展出更大的展帆面积,有效利用风能,同时保证在不利风况及船舶进出港口和装卸货时能自动折叠收帆,占用较小甲板面积,不影响船舶航行与货运安全.同时利用CFD软件对翼型的气动特性进行了数值模拟计算,并与传统风帆实验数据进行对比,证明其具有高升高阻的特性且推力系数较之传统风帆有显著提高.

In order to ensure the safety of the ship and promote the full usage of clean energy at sea,a new kind of ship propulsion-assisted wing sail device was proposed. Focusing on more automatic and flexible structural features of the device,it is designed to increase the efficiency of wind by enlarging areas when wind conditions get available. In the meanwhile,it can be folded up automatically,which takes up little deck space and does not interfere with the ship＇ s sail. The result of lift coefficient and drag coefficient were compared between numerical simulation and traditional aerofoil sail experimental data,which proves that the new device is better than a traditional aerofoil sail.
