本発明は、船尾においてプロペラと舵とをそれぞれ左右
に対をなしてそなえた高速艇に関し、特に舵の形状の改
良をはかった２輪２舵型高速艇に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a high-speed boat that is equipped with a propeller and a rudder in pairs on the left and right sides at the stern, and particularly relates to a two-wheeled two-rudder boat with an improved shape of the rudder. Regarding type high-speed boats.
第４〜６図は従来の２軸２舵型高速艇を示すもので、第
゛４図はその側面図、第５図はその底面図、第６図はそ
の舵の見取図である。4 to 6 show a conventional two-shaft, two-rudder type high-speed boat, in which FIG. 4 is a side view, FIG. 5 is a bottom view, and FIG. 6 is a sketch of the rudder.
これらの図に示すように、船尾に設けられた左右一対の
プロペラ２の相互間において、同プロペラ２よりも後方
に左右一対の舵板１が設けられており、舵板１は倒立台
形状の平板からなる単板舵として形成されている。As shown in these figures, between a pair of left and right propellers 2 provided at the stern, a pair of left and right rudder plates 1 are provided behind the propellers 2, and the rudder plates 1 are in the shape of an inverted trapezoid. It is constructed as a single-plate rudder consisting of a flat plate.
すなわち、小型高速艇では、舵板１に流れ込む水の流速
が速いことや、ステンレス鋼で舵板１を製作する場合の
工作の簡易化をはかることなどのために、舵板１は単板
舵として形成されてプロペラ２よりも内側に配設されて
いる。That is, in small high-speed boats, the rudder plate 1 is used as a single-plate rudder because the flow rate of water flowing into the rudder plate 1 is fast and to simplify the work when manufacturing the rudder plate 1 from stainless steel. The propeller 2 is formed and arranged inside the propeller 2.
しかしながら、上述のような従来の２軸２舵型高速艇で
は、プロペラ２の後流の影響を受ける舵板１の外側面に
沿う水の流れが、舵板１の内側面に沿う水の流れよりも
速（なって、舵板１の内外側における圧力のアンバラン
スを生じ、洗場の乱れを促進して、推進性能上好ましく
ない現象を生じるという問題点がある。However, in the conventional two-shaft, two-rudder type high-speed boat as described above, the flow of water along the outer surface of the rudder plate 1, which is affected by the wake of the propeller 2, is faster than the flow of water along the inner surface of the rudder plate 1. There is a problem in that this causes an unbalance of pressure between the inside and outside of the steering plate 1, promoting disturbance in the washing area, and causing an unfavorable phenomenon in terms of propulsion performance.
本発明は、このような問題点の解決をはかろうとするも
ので、プロペラに対する舵板の位置関係に応じて舵板の
形状を改善することにより、推進性能の向上をはかれる
ようにした、２紬２舵型高速艇を提供することを目的と
する。The present invention aims to solve these problems, and aims to improve the propulsion performance by improving the shape of the rudder plate according to the positional relationship of the rudder plate with respect to the propeller. The purpose is to provide a high-speed boat with two rudders.
このため本発明の２軸２舵型高速艇は、船尾に設けられ

おいて同プロペラよりも後方に配設された左右一対の舵

側方の上記プロペラ側に屈曲して形成されていることを
特徴としている。For this reason, the two-shaft, two-rudder type high-speed boat of the present invention includes a pair of left and right propellers provided at the stern, and a pair of left and right rudder plates arranged between these propellers and behind the propellers. The steering plate is characterized by an inverted triangular leading edge portion bent outward toward the propeller.

されているので、舵板の外側面および内側面に沿う各水
流の速さがほぼ等しくなって、舵板の内外側における圧
力のアンバランスを生じなくなり、渡場の乱れを促進す
るようなことがなくなる。In the above-described two-axle, two-rudder type high-speed boat of the present invention, the pair of left and right rudder plates arranged rearward of the pair of left and right propellers between the pair of left and right propellers have an inverted triangular leading edge portion, Since the leading edge portion is bent outward toward the propeller side, the speed of each water flow along the outer and inner surfaces of the rudder plate is approximately equal, and the pressure on the inner and outer sides of the rudder plate is reduced. Unbalance will no longer occur and there will be no possibility of promoting disorder in the ford.
また操舵時には、舵板が回動することにより、通常の舵
の場合と同様に、船体の回頭が行なわれる。Further, during steering, the rudder plate rotates to turn the hull, as in the case of a normal rudder.

The figure is a sketch of the rudder, and Figure @3 is a sectional view taken along the line m-III in Figure 2.

すごとく折り曲げられていで、特に、ｔｊＳ１図に示す
ように、この前縁部分１ａは外側方のプロペラ２の側に
屈曲して形成されている。As shown in Fig. tjS1, in the case of this small high-speed boat, as well as in the conventional case, a pair of left and right rudder plates 1 are located behind the propellers 2 between the pair of left and right propellers 2 provided at the stern. 6 and the rudder plate 1 is provided with f
As shown in Figure 2, the rudder is formed as a stainless steel single-plate rudder in the shape of an inverted trapezoid, but in the case of the present invention, the inverted triangular leading edge portion 1a of the rudder plate 1 is It is bent as shown in the figure, and in particular, as shown in Figure tjS1, this leading edge portion 1a is bent outward toward the propeller 2 side.
したがって、プロペラ２の作動により船体が前進してい
る場合に、舵板１の外側面のみがプロペラ後流の影響を
受けて舵板１の内側面よりも速い水流を生じるというよ
うなことがなくなる。Therefore, when the ship is moving forward due to the operation of the propeller 2, it is no longer possible for only the outer surface of the rudder plate 1 to be affected by the wake of the propeller and to generate a water flow faster than the inner surface of the rudder plate 1. .
すなわち、舵板１の内外側面に沿う水流の速さがほぼ等
しくなって、舵板１の内外側における圧力のアンバラン
スを生じなくなり、従来の場合のように渡場の乱れを促
進するというようなことは起こらない。In other words, the speed of the water flow along the inner and outer surfaces of the rudder plate 1 becomes almost equal, and the pressure imbalance between the inner and outer sides of the rudder plate 1 no longer occurs, which promotes turbulence in the ford as in the conventional case. Nothing happens.
なお、屈曲された前縁部分１ａが、倒立三角形状に形成
されていることにより、プロペラ後流の影響を受けやす
い舵板上部はど、前縁部分１ａの作用で上記影響の防止
がはかられるようになっている。In addition, since the bent leading edge portion 1a is formed into an inverted triangular shape, the upper part of the rudder plate is susceptible to the influence of the propeller wake, but the effect of the leading edge portion 1a is difficult to prevent the above-mentioned influence. It is now possible to
このようにして本発明の２軸２舵型高速艇では、船尾の
渡場が適切に保たれるので、推進性能の向上がもたらさ
れるのである。In this way, in the two-shaft, two-rudder type high-speed boat of the present invention, the stern crossing area is maintained appropriately, resulting in improved propulsion performance.
また舵板１の前縁部分１ａが屈曲していても、操舵時に
支障をきたすことはなく、通常の舵取装置により、従来
の場合と同様に舵板１を回動させて、その舵角に応じ船
体の舵取りを行なうことがで終る。Furthermore, even if the leading edge portion 1a of the steering plate 1 is bent, it will not cause any problem during steering, and the steering plate 1 can be rotated using a normal steering device in the same way as in the conventional case, and the steering angle can be adjusted. This ends with steering the ship accordingly.

である。As detailed above, according to the two-shaft, two-rudder type high-speed boat of the present invention, a pair of left and right propellers are provided at the stern, and a pair of left and right propellers are provided between these propellers and rearward of the propellers. It has a simple structure in which the inverted triangular leading edge of the rudder plate is bent outward toward the propeller side, making it possible to maintain the stern crossing area appropriately. This can contribute to improving propulsion performance.
