    • PROBLEM TO BE SOLVED: To provide the design of a swim fin, which gives high safety and big pleasure. SOLUTION: A method, which increases the dynamic lift of a hydrofoil and the swim fin and decreases resistance, is disclosed. This method includes the hydrofoil (104), which is equipped with a leading edge (108) greatly retreated and is oriented to an attack angle fairly reduced, and this reduced attack angle is substantially produced at an angle of a lateral direction to the direction of the hydrofoil which moves in a surrounding fluid medium. The method, in which the hydrofoil (104) is equipped with a recess of a substantially longitudinal direction which is substantially arranged along the center axis of the hydrofoil, i.e., a flow mechanism, is indicated. Since this central recess, i.e., the flow mechanism makes it possible that water flows as it remains clinging along the leeward side surface of the hydrofoil and joins water flowing from an attack surface through the recess, i.e., the flow mechanism, the dynamic lift is effectively generated.

    • 要解决的问题:提供游泳鳍片的设计,提供高安全性和高度的乐趣。 解决方案:公开了一种增加水翼和游翅的动态升力并降低阻力的方法。 该方法包括水翼(104),其配备有大大退缩的前缘(108)并且被定向成相当减小的攻角,并且这种减小的攻角基本上以横向方向 在周围的流体介质中移动的水翼。 表示其中水翼(104)配备有沿水翼的中心轴线(即,流动机构)基本上布置的基本纵向方向的凹部的方法。 由于这种中心凹槽,即流动机构使得水沿着水翼的背风侧表面保持流动,并且使从入口表面流过的水通过凹槽(即,流动机构)连接起来,水的流动是可能的 有效产生。 版权所有(C)2008,JPO&INPIT

    • PURPOSE:To moderate a water shock at the time of cutting waves, by a method wherein a hydrofoil V-shaped in cross section, isosceles triangle shaped in plan view with the vertex on the fore side and having outside edges set to be higher than the root of splashes at the time of high-speed cruising is provided at a fore part or at fore and back parts of a ship's hull in a manner of being projected from the ship's bottom. CONSTITUTION:In a high speed vessel wherein a means for generating a lift balancing with the entire weight of the vessel is provided at a fore part or at fore and back parts of the ship's hull, a hydrofoil 11 V-shaped in cross section, isosceles triangle shaped in plan view with the vertex on the fore side and having the outside edges 12 set to be higher than the root of splashes at the time of high-speed cruising is provided as the means. The outside edges 12 are provided with flares 14 to horizontally fly the receding waves in transverse directions and to prevent splashes from colliding against the ship's bottom. Accordingly, the water shock generated at the time of cutting waves during the high- speed cruising is moderated, and wave resistance of the vessel as a whole is enhanced.
    • 目的:为了减轻切割波浪时的水冲击,通过一种方法,其中横截面为V形的水翼,在俯视图中具有三角形的三角形形状,顶边处于前侧,并且具有高于 以船舶底部的方式,在船体的前部或前后部分设置高速巡航时的飞溅根部。 构成:在船体的前部或前后部设置用于产生具有整个容器整体的升降平衡的装置的高速船,横截面为十V形的水翼,等腰 提供了在高速巡航时具有前侧的顶点并具有设定为高于飞溅根部的外边缘12的三角形形状的平面图。 外侧边缘12设置有横梁14的横向飞行,并且防止飞溅与船的底部碰撞。 因此,在高速巡航期间切断波浪时产生的水冲击减轻,并且整体上容器的波阻提高。
