Definitions
- the present invention relates to a front twin ladder propeller ship having one propeller shaft and two rudders in the bow direction of the propeller.
- Ships are used as a means to transport goods and people in large quantities and efficiently. Therefore, since it is important for ships to safely call and navigate the intended route, the ship's propulsion mechanism and rudder mechanism have evolved and evolved.
- the basic elements required for a rudder are turning performance (a performance that shows how quickly the course can be bent when the rudder is kept turning), and needle maintenance (course stability: how to run straight These are often contradictory functions, but various attempts have been made to make them compatible. Due to the ship's rotational performance, the relationship with the ship's main body, the effect of water flow on the rudder, etc., it has become common for the stern to be attached in tandem at a position behind the propeller.
- the effect of the rudder is the same as that of airplanes and other wing theory, and it is well installed in a limited space at the stern.
- the rotational performance of the rudder depends on the lateral thrust acting on the surface of the rudder. This is the lift that acts on the control surface. In a theoretically uniform laminar flow, lift is expressed by the following equation as the performance of the rudder alone.
- Lift (F) 1 / 2 ⁇ V 2 ⁇ sin ⁇ ⁇ A ⁇ Fp
- V water inflow speed to the rudder
- ⁇ inflow angle to the rudder of the inflow water
- A effective area for the lift of the rudder
- Fp gradient of the direct pressure coefficient of the rudder alone
- ⁇ density of seawater
- Patent Document 1 in order to increase the lift of the rudder, it is known in Patent Document 1 that, in a special ship, two rudders are provided in parallel at the rear of the propeller on the stern.
- Patent Document 1 Although the configuration of Patent Document 1 has the advantage that the lift can be increased, there is no idea of improving the fuel consumption, reducing the price of the built ship, or increasing the load per ship.
- the main problem of the present invention is to provide a propeller ship structure that can improve fuel consumption, increase the load per ship, and reduce the construction ship price.
- a front twin-ladder propeller ship characterized in that a rudder is provided in front of the propeller and behind the buttocks line and in a symmetrical position with respect to the center line of the ship.
- a rudder was provided at each position symmetrical to the center line of the ship.
- the rudder area required to ensure the necessary turning performance and needle-keeping performance (course stability) for a ship of a certain size is as follows: It can be reduced to about 25% to 50% per rudder area.
- the total area of the two rudders is the same as or slightly larger than the conventional one rudder. It is desirable to provide the rudder so that the clearance with the ship bottom line is as small as possible. In general, it is necessary for the rudder to be submerged from the sea level when sailing.
- the ability to reduce the rudder height according to the present invention means that the drafting depth can be reduced during voyage.
- the “buttock line” means a stern shape line cut along a vertical plane parallel to the hull center longitudinal section. In particular, it refers to the line formed by the intersection line with the parallel part of the hull.
- the stern thruster is preferably located 3 to 25 m ahead of the propeller. When located 3 to 25 meters ahead of the propeller, it was found that the trajectory correction in a narrow port and the ship maneuverability by Stearns thruster at the berthing and landing were suitable positions.
- the present invention is not characterized by the shape of the surface of the rudder, but is intended to use a general rudder.
- the maneuverability can be improved by using the two rudders synchronously, independently, or in combination.
- the rudder and steering gear are installed in front of the propeller, for example, the rear peak tank of the ship, the steering chamber (steering chamber), etc., do not need to be extended to the rear, and a single rudder is installed behind the conventional propeller.
- it can be shortened by about 5 to 20 m compared to the propeller ship.
- the volume of the cargo tank can be increased by about 5% to 15% per the same total length, the utility value of the ship is increased.
- the total length of the ship can be shortened and the construction ship price will be reduced.
- an additional propeller and its driving means are provided, and the additional propeller is located at a position different from the arrangement position of the propeller, and one or a plurality of the additional propellers are arranged at the bottom of the ship or at the bottom of the ship and drive the propeller.
- a small additional propeller and its driving means are provided.
- the output of the driving means of the additional propeller can be 35% or less, more preferably 25% or less of the output of the driving means of the main machine.
- the propeller is driven and operated in a draft state close to the planned full draft. If necessary, operate with additional propellers. Mainly operated with a small additional propeller, returning to the port after unloading. In particular, on days when the weather is mild, there is little need to be overly strict about the stability of the ship during navigation. Therefore, it is made to run with a small additional propeller in a state where the water line is lowered.
- a propeller is a rudder ship, and an engine room 50 is arranged in a hull of a stern part. Propeller 51 is driven by rotating.
- a rudder 52 is provided behind the propeller 51, a steering chamber (steering chamber) 53 above the propeller 51 is disposed, a steering device 54 is provided therein, and a rudder shaft 55 is connected to the rudder (steer plate) 52. It is integrated, and the ship can turn by the steering machine 54.
- Reference numeral 56 denotes an after peak tank.
- a cargo portion 57 is arranged in front of the engine room 50 so as to be connected to the bow side.
- FIG. 1 to 6 show an example of a front twin ladder propeller ship of the present invention.
- the present invention is characterized in that rudders 12 and 12 are provided in front of the propeller 11 and behind the buttocks line, respectively, at symmetrical positions with respect to the center line of the ship.
- the rudder 12 may be either a balance type or an unbalance type in relation to the rudder shaft 12a. Moreover, it is desirable to have a symmetrical control surface as shown in FIG.
- the two rudders 12 and 12 can be appropriately selected from synchronous use, single use, combined use, and the like.
- the steering room (steering room) 53 is also arranged in front of the propeller 11, and a steering machine 54 is provided therein.
- a Stance raster 40 can be provided in front of the propeller 11 and behind the buttocks line. Further, the propeller axis 40a of the stern thruster 40 is disposed so as to pass through the rudder plate surfaces of the rudder 12 and 12. By providing the stern thruster 40 on the stern side, it is possible to improve the trajectory correction in a narrow port and ship maneuverability in berthing and landing. On the other hand, when a ship is navigating at a low speed such as in a harbor, the rudder is very ineffective. Therefore, by starting the stern thruster 40 and causing the water flow to flow into the rudder plate surface, the effectiveness of the rudder is accelerated and the maneuverability is improved.
- the Stance raster 40 is preferably located 3 to 25 m ahead of the propeller.
- the rudder and its steering device are provided in front of the propeller, for example, an after-peak tank 56 of a ship, a steering chamber (steering chamber) 53 (see FIG. 7), as in the conventional example shown in FIGS.
- the conventional propeller can be shortened by about 5 m to 20 m compared to a propeller ship having one rudder behind the propeller.
- the volume of the cargo tank can be increased by about 5% to 15% per the same total length, the utility value of the ship is increased. Also, the construction ship price can be reduced.
- the propeller 11 is a regular propeller. As shown in FIGS. 4 to 6, in addition to the regular propeller 11, an additional propeller and its driving means are provided.

Abstract
Description
そのために、船には目的の航路を安全に寄港し、航行することが重要であるので、船の推進機構及び舵機構は変遷しながら発展してきた。
船の回転性能、船本体との取り合い、舵に対する水流効果等から、船尾において、プロペラに対し後方の位置にタンデムに取り付けられるのが一般化した。
揚力(F)=1/2ρV2・sinα・A・Fp
ここで V:舵に対する水の流入速度
α:流入水の舵に対する流入角度
A:舵の揚力に対する有効面積
Fp:舵単独の直圧力係数の勾配
ρ:海水の密度
<請求項1記載の発明>
プロペラの前方かつバトックラインの後方であって、船の中心線の左右対称位置に、それぞれ舵を設けたことを特徴とする前置きツインラダープロペラ船。
船の中心線の左右対称位置に、それぞれ舵を設けた。ある大きさの船における必要な旋回性及び保針性(針路安定性)を確保するために必要な舵面積は、2つの舵による場合における各舵の面積は、一つの舵による場合より、1つの舵面積当たり25%~50%程度に小さくできる。2つの舵の総面積では、従来の一つの舵と同一面積または少し大きくなる。舵は、船底線とのクリアランスを極力小さくするように設けることが望ましい。
一般に航海時に舵は海水面より没していることが必要である。本発明に従って舵高さを小さくできることは、航海時に喫水深さを浅くすることができることを意味し、その結果、同一船速に対して主機関の出力を低減することができ、燃費が改善する。
他方、プロペラの前方にスターンスラスター(stern thruster)を設けることにより、スターンスラスターによる効果を期待できる。
なお、「バトックライン」(buttock line)とは、船体中央縦断面に平行な鉛直面で切った船尾の形状線を意味する。特に船体の平行部との交差線とがなす線を言う。
プロペラの前方でかつバトックラインの後方にスターンスラスターを設け、このスターンスラスターのプロペラ軸線が、前記各舵板面を通る関係にある請求項1記載の前置きツインラダープロペラ船。
船尾側にスターンスラスターを設けることにより、狭い港内での軌道修正や離着岸における操船性を高めることができる。
他方、港内など船が低速で航行している場合、舵の効きは極めて悪い。そこで、スターンスラスターを起動させ、その水流を舵板面に流入させることにより、操船性が高まる。
前記スターンスラスターは、前記プロペラより3~25m前方に位置する請求項32記載の前置きツインラダープロペラ船。
スターンスラスターは、プロペラより3~25m前方に位置するのが好ましい。プロペラより3~25m前方に位置する場合には、狭い港内での軌道修正や離着岸におけるスターンスラスターによる操船性が好適な位置であることが判った。
舵は、左右対称の舵面を有する請求項1記載の前置きツインラダープロペラ船。
本発明は舵の面形状に特徴を有するものではなく、一般的な舵を使用することを念頭に置いている。舵が、左右対称の舵面を有すると、二つの舵を同期使用、単独使用、組み合わせ使用等により操船性を高めることができる。
操舵機がプロペラの前方でかつバトックラインの後方の船体内に設けられている請求項1記載の前置きツインラダープロペラ船。
舵及び操舵機をプロペラの前方に設けると、たとえば船のアフターピークタンク、操舵室(ステアリング室)などの後方への張出しが不要となり、従来の一つのプロペラに対してその後方に一つの舵を有するプロペラ船に比較して、たとえば約5m~20m短くすることができる。
その結果、貨物船の場合、同一の全長当たり、貨物槽の容積を約5%~15%増加できるので、船の利用価値が高まる。また船の全長を短縮でき建造船価が低減する。
前記プロペラのほか、追加プロペラ及びその駆動手段が設け、前記追加プロペラは、前記プロペラの配置位置とは異なる位置であって、船底又は船底立ち上がり部に一台または複数台配置し、プロペラを駆動して推進力を得る常用運転状態と、追加プロペラを駆動して推進力を得る運転状態とを選択可能とした請求項1記載の前置きツインラダープロペラ船。
前記プロペラ、すなわち常用プロペラ以外に、小型の追加プロペラ及びその駆動手段を設ける。追加プロペラの駆動手段の出力は、前記主機の駆動手段の出力の35%以下、より好ましくは25%以下とすることができる。
載荷(積荷)時には、計画満載喫水に近い喫水状態で、常用プロペラを駆動して運行する。必要あれば追加プロペラを併用して運航する。
荷下ろし後の帰港航海、小型の追加プロペラで主として運航する。とりわけ天候が穏やかな日においては、船舶の航海時の安定性につき過度に厳格とする必要性に乏しい。そこで、喫水線を下げた状態で、小型の追加プロペラにて走行させる。
その結果、喫水線を下げることにより、見掛け上の排水量の低下となり、外板の水との接触面積が小さくなり、水線面積係数の改善を図ることができ、燃料消費の低減効果が大きいものとなる。
また、小型の追加プロペラを駆動するので、駆動装置の出力(主機の駆動手段の出力の35%以下、より望ましくは25%以下)は小さいもので足り、この観点からも、燃料消費の低減効果が大きいものとなる。
船舶が積荷を満載した後に出港し、通常の航海に移行する場合には、常用プロペラを駆動し、深い喫水で航海する。また、揚荷後バラストで航海する場合は通常航海状態に移行後に追加プロペラ運航とする。ただし天候が悪い場合には、たとえ空船であっても、バラスト水を張り、安定化させた状態で、小型の追加プロペラ又は常用プロペラにて走行させることができる。また必要な場合、追加プロペラ及び常用プロペラを併用することも可能である。
バラスト航海時に主として追加小型プロペラを使用することにより、常用プロペラのプロペラ没水率の制限が少なくなり、設計された(designed)プロペラのプロペラ直径を、従来の設計基準によるプロペラの直径より大きくできる。これによりプロペラ効率アップが可能となり、約5~7%の効率アップとなる。かくして、より大きな直径の設計された(designed)プロペラ採用により、プロペラ効率がアップし同一船速に対し主機関の必要出力は減少し。これにより大きな燃費改善となる。
前記追加プロペラは、船外への張出し状態と船内への引き込み状態とを選択可能である請求項6記載の前置きツインラダープロペラ船。
追加プロペラが船外へ張出し状態にあり、航海中、使用しない状態におかれる場合には、深い喫水において抵抗になるので、追加プロペラは、船内へ引き込み状態とすることが望ましいのである。
機関室50の前方には貨物部57が船首側に連なって配置されている。
図1~図6は本発明の前置きツインラダープロペラ船の一例を示している。
船尾側にスターンスラスター40を設けることにより、狭い港内での軌道修正や離着岸における操船性を高めることができる。
他方、港内など船が低速で航行している場合、舵の効きは極めて悪い。そこで、スターンスラスター40を起動させ、その水流を舵板面に流入させることにより、舵の効きが速まり操船性が高まる。
その結果、貨物船の場合、同一の全長当たり、貨物槽の容積を約5%~15%増加できるので、船の利用価値が高まる。また建造船価を低減できる。
この追加プロペラ20は、常用プロペラ11とは異なる位置、すなわち図示の船首領域ほか、船尾又は中間位置であって、船底又は船底立ち上がり部に配置される。船尾位置の場合を符号20A、中間位置の場合を符号20Bで示している。
そして、常用プロペラ11を駆動して推進力を得る常用運転状態と、追加プロペラ20を駆動して推進力を得る運転状態とを選択可能とされている。
他方、駆動手段22による伝達軸28の回転駆動力は、駆動小歯車29、これに噛合する大歯車30に伝達され、ダクトプロペラ21を縦軸25回りに回転可能に構成されている。
荷下ろし後は、とりわけ天候が穏やかな日、あるいは波の静かな海においては、船舶の航海時の安定性につき過度に厳格とする必要性に乏しいので、図5に示すように、喫水線を下げた状態で、小型の追加プロペラ20にて走行させる。この場合、図5の白抜き矢印で示すように船の進行方向は適宜選択でき、船の進行方向によりブリッジ13で船首、船尾を監視する。
その結果、喫水線を下げることにより、見掛け上の排水量の低下となり、外板の水との接触面積が小さくなり、水線面積係数の改善を図ることができ、燃料消費の低減効果が大きいものとなる。
また、小型の追加プロペラ20を駆動するので、駆動装置22の出力は小さいもので足り、主機50の駆動手段の出力の35%以下、特に25%以下、とりわけ10%~5%程度の出力で航行できる観点からも、燃料消費の低減効果が大きいものとなる。天候が穏やかな日(ビューフォートスケールで0~3の日)での走行速度は5~10ノット程度で十分である。
また、天候が悪い場合には、たとえ空船であっても、バラスト水BW(バラスト水の貯留空間は図示していない。)を張り、安定化させた状態で、小型の追加プロペラ20又は常用プロペラ11にて走行させることができる。
