【摘要】 不对称尾鳍是安装在单桨船螺旋桨前方艉柱上的一种节能装置.文章分析了不对称尾鳍的节能原理,并以三艘具有不同尾型的船模试验结果证明,采用不对称尾鳍后的节能效果是非常明显的.这种类似于不对称船尾的节能装置由于结构简单,安装方便,成本低,节能效果显著等优点而值得推广.更多还原

【Abstract】 The asymmetrical skeg is an energy-saving unit which is fixed on the sternpost forward of the propeller on a single screw ship. The paper analyzes the energy-saving principle of the asymmetrical skeg. The model test results of the three ships with different stern forms show that energy is saved obviously when the asymmetrical skeg is installed. This kind of energy-saving unit similar to asymmetrical stern has advantages of simple structure, easy installation, low cost and obvious effect of energy-saving and it is worth to be promoted.更多还原
