Abstract

本实用新型涉及一种船舶，特别适合于其尾型是单涡尾船型。本实用新型为以从船尾至船首方向设计水线以下40％水线长区域内不对称船体型线构成左、右旋的单涡尾船型。本船型与现役的700TEU集装箱船比较，在设计航速范围内Q.P.C值有显著提高，达0.72-0.74，可节省主机功率达17％。

Description

一种涡尾船型
本实用新型涉及一种船舶，特别适合于其尾型是单涡尾船型。
意大利人G.B.TORMMASSI发明的蜗槽尾，使用于单桨海船的蜗槽尾见1982年I.S.P刊物上(International ShipbuildingProgress.V 01 29.NO.331)，但他提出的蜗槽尾的蜗体部分是从船舯一直到船尾即约为50％的水线长。这导致了在性能推进效率和阻力的同时增加，浪费了可节省的主机功率；在技术运用上，导致蜗体加工复杂，增加船舶造价和影响货船舱容及机舱布置，也末考虑船舶改造的因素。上述诸因素导致该技术失去其实用性而未能推广使用。
针对上述现有技术存在的缺点，本实用新型的目的是提供一种单涡尾船型。
本实用新型通过以下技术措施实施，本发明的蜗体部分为以从船尾至船首方向设计水线以下40％水线长区域内不对称船体型线构成左旋的单涡尾船型，或蜗体部分为以从船尾至船首方向设计水线以下40％水线长区域内不对称船体型线构成右旋的单涡尾船型。
本实用新型的优点是：(一)保证涡尾船因湿表面积增加而使阻力增加的幅度不过大或常规船阻力相当。(二)不影响机舱布置，减少加工难度和造价。
附图说明如下：
附图1：母型船700TEU尾部线型图(左舷，右舷与之对称)；
附图2：本实用新型单涡尾船尾部线型图；
附图3：单涡尾船的侧视图，图中1为原始船体；2为改型区域。
结合附图对本实用新型进一步说明如下：
以中国远洋运输总公司提供的700TEU集装箱船为母型船进行了改型船——单涡尾船船模试验，保证了单涡尾船的排水量，设计水线形状，主尺度与母型船一样，横截面面积曲线和浮心纵向位置基本一样。线型改造区域为设计水线以下从尾到首15％水线长。试验结果表明，节省主机功率17.1％，推进效率达0.74。试验结果如表1所示：
