Abstract
Description
【発明の詳細な説明】
この発明は、船体に取り付ける水中翼のうち推進力を発
生させる効果を有する水中翼に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hydrofoil that is attached to a hull and has the effect of generating propulsive force.
従来の船体に取り付けられている水中翼では単に船体の
姿勢の安定化と、さらにそれに伴う船体の縦揺れOこよ
り増加する造波抵抗の軽減を意とした構造のものが多い
が、直接水中翼による推進力を得る構造のものではない
。Many of the conventional hydrofoils attached to the hull are designed to simply stabilize the hull's attitude and reduce the wave-making resistance that increases due to the accompanying pitching of the hull. It is not a structure that obtains propulsion force.
この発明の推進力を発生させる水中翼は、自然エネルギ
ーである波力を直接推進力として利用し、船体の造波抵
抗による船の速度の低下を抑制し、さらに船体の縦揺れ
をも抑制するものである。The hydrofoil that generates propulsive force of this invention uses wave power, which is natural energy, as direct propulsion force, and suppresses the reduction in ship speed due to wave-making resistance of the ship's hull, and further suppresses the pitching of the ship's hull. It is something.
第1図に示すように、水中翼2は、後方にたわみのある
構造であり、船体が波力の影響により縦揺れをおこす場
合、たとえば、船首部分が下がり水中に没するような運
動をする場合には、水中翼2の後部は、上部にふくらみ
、船体の縦揺れエネルギーを使用して、水を後方へ押し
出し、その反作用により推進力を発生させる。As shown in Fig. 1, the hydrofoil 2 has a structure that bends backwards, and when the hull of the ship pitches due to the influence of wave force, for example, the bow part moves downward and sinks into the water. In this case, the rear part of the hydrofoil 2 bulges upward and uses the pitching energy of the hull to push water backwards and generate propulsive force by its reaction.
同時に、水中翼面2には船体の縦揺れ方向にス]して抵
抗が発生するため、船体の縦揺れ運動を抑制する。At the same time, since resistance is generated on the hydrofoil surface 2 in the pitching direction of the hull, the pitching motion of the hull is suppressed.
反対に、船首部分が浮き上がる運動をする場合には、逆
に水中翼2の後部は、下部にふくらみ。On the other hand, when the bow part moves upward, the rear part of the hydrofoil 2 bulges downward.
同様に推進力を発生させる。Propulsive force is generated in the same way.
このようにして、船体の縦揺れ運動の」二下動のどちら
に対しても推進力が得られ、又、水中翼2がたわみのあ
る構造であるため船の進行方向に対する抵抗を少なくす
ることができる。In this way, propulsive force can be obtained for both the vertical and downward motions of the ship, and since the hydrofoils 2 have a flexible structure, the resistance in the ship's traveling direction can be reduced. I can do it.
船体の縦揺れ運動は、造波抵抗を増大させ、船の速度の
低下、さらに揺れのひどい場合には。The pitching motion of the ship increases wave-making resistance, which reduces the ship's speed and, in severe cases, increases the wave-making resistance.
沈没の危険や人体の不快など、多くの問題があるが、そ
の他にも船体の揺れに関する原因である波力や風等、自
然エネルギーからの影響は大である。There are many problems, such as the risk of sinking and discomfort to the human body, but there are also significant effects from natural energy such as wave force and wind, which are the causes of the ship's rocking.
この発明の波力を使用し、推進力を発生させる水中翼は
2以上説明したようにして、自然エイ・ルギーである波
力を使用し、推進力の発生。The hydrofoil of the present invention uses wave power to generate propulsion force as described above, and generates propulsion force by using wave force, which is natural energy.
縦揺れの抑制を行い、船体の安定化、さらに造波抵抗に
よる影響の軽減を図るものである。This aims to suppress pitching, stabilize the ship, and reduce the effects of wave-making resistance.
