Abstract

一种船体的特征是：在吃水线(CWL)下面的船体由一个几乎在船全长上延伸的、***状的排水体构成，该排水体在船头部分是狭长的，而往其后，均匀加厚地越过大约船长的2/3，然后朝着一个大的中间螺旋桨(P)的方向再逐渐变尖，并与该排水体向上连接着一个V形构架特征的船型，在该船型后面区域转入一个通道结构，该通道在凸出部的上面形成一个急骤凹陷的盆腔型结构。

Description

本发明涉及一种适用于具静态和动态浮力的小型运输工具和高速性能的船体。
快速的小船，特别是摩托艇和军用船，多半是双螺旋桨结构，因为用两个或四个螺旋桨结构时，螺旋桨的气蚀倾向可以减少，并且能避免推力的一种流体动力不均匀性。此外，以前还没有可供使用的适宜高功率的动力装置。
最后，今天也还运用下述的论点，对于双螺旋桨的情况，当一个动力装置停转时仍可在很大程度上维持运转的准备工作，并使双螺旋桨驱动能有较好的机动性能。
在商船的行驶中，多螺旋桨驱动在最近的10至15年中几乎完全被放弃了，因为使用单螺旋桨可期望在投资方面节约大致10%，而在燃料消耗方面大约节省15%。此外，如果配备一个中间桨的话，船的操纵性能在慢速行驶的情况下比起双螺旋桨有根本地改善。
因此，在快速小船的情况下，特别是在摩托艇和军用船的情况下用单螺旋桨代替双蝇旋桨驱动就是本发明的任务。这一任务基于避免有害的气蚀和由此产生的噪声与振动。
作为避免气蚀的解决措施是公知的：
1.一个在轴向、径向和切向上均匀的尾流场;
2.避免一种斜入射流;
3.选择一个大的螺旋桨直径和/或一个面积比;以及
4.将功率分配在两个串联设置的螺旋桨上。（对抗-旋转-螺旋桨）。
本发明的解决措施可由下列的技术方案得到解决。根据本发明，吃水线（CWL）下面的船体由一个几乎在全船长度上延伸的降起状排水体构成，该排水体在船头部分是狭长的，而往后面，均匀加厚地越过大约船长的2/3，然后，向着一个大的中间螺旋桨（P）的方向再逐渐变尖，并与排水体向上连接有一个V型构架特征的船型，该船型在它后面区域转入一个通道结构，该通道笼罩着凸出体和螺旋桨，以使得该外凸出部的上面形成一个急骤凹陷的盆腔型构造。而且船体的一个或多个吃水线（如吃水线3）由单独的平面构成，在船体的尾部还设置有两辅助的驱动器。作为本发明所导致的优点和改善，尤在小快艇的情况下，可期望达到：
1.由于排水重心的向后位移而减少船体的阻力，也就是说，通过在船前方产生较小的入水角;
2.消除侧面的螺旋桨轴的支座阻力（总阻力的10-15%）;
3.通过充分利用排水尾流改善船的质量等级（5-10%）;
4.在CR-螺旋桨结构的情况下，由第一螺旋桨的排流中回收旋转能量（5-10%）。
这些改善可实现例如有效距离（续航距离）和/或对零散设备的有效载荷的增大，或使船体缩小。
本发明由附图1-4得出一个图解说明，特别是一个摩托艇的侧视图和船体轮廓图。
它展示：
图1    是本发明船体的一个侧视图，并对应于图4的构架草图;
图2    是本发明按图1A-A线的水平截面看船底的仰视图;
图3    和图4是本发明一个船型的吃水线和构架的草图。
