Description

나선형 추진기와 병렬로 배치되는 선박용 타{Standing in law type propeller and rudder}Ship rudder arranged in parallel with helical thruster {Standing in law type propeller and rudder}

본 발명은 나선형 추진기와 병렬로 배치되는 선박용 타에 관한 것으로, 보다 상세하게는 나선형 추진기를 선미 끝단에 배치하여 수선을 연장하고, 상기 나선형 추진기 양측에 타를 병렬 배치하여 저항을 감소시키고 추진성능을 극대화하며, 선박의 전체 길이 대비 잠수된 선체의 측면적을 넓힘으로써 조종성능을 위한 기본적 포텐셜을 높일 수 있도록 한 나선형 추진기와 병렬로 배치되는 선박용 타에 관한 것이다.The present invention relates to a ship rudder arranged in parallel with the helical thruster, and more particularly, to extend the waterline by arranging the helical thruster at the stern end, by placing the rudder on both sides of the helical thruster to reduce resistance and improve the propulsion performance. The present invention relates to a ship's rudder arranged in parallel with a spiral thruster that maximizes and expands the lateral area of the submerged hull relative to the overall length of the ship, thereby increasing the basic potential for steering performance.

일반적으로 선박용 타는 도 4에서 도시한 바와 같이 나선형 추진기 후방에 한 개의 타가 직렬 배치되어 추진기 전방에서 선체가 비대하여 유선 축소율이 급격하고, 이로 인해 유체의 박리현상이 상대적으로 일찍 발생함으로써 점성 저항의 증가를 발생시킨다. 또한 자항측면에서는 나선형 추진기로 유입되는 유체의 유입각이 커서 추력의 감소 요인이 됨과 동시에 추진기 단독 특성상 효율저하가 전체 전달효율 감소로 이어져 일정 선속을 위한 소요 마력이 증가하게 되는 문제점이 있어서 유체가 선체 표면을 원활히 따라 흐르게 하여 유체 박리점을 선미 후방으로 이동시켜서 선체의 점성 저항을 감소시키고 추진기로 유입되는 유체의 유입각을 감소시켜 유체의 추진기로의 유입을 원활하게 하여 추진효율을 증가시킬 수 있는 나선형 추진기와 병렬로 배치되는 선박용 타가 요구되고 있는 실정이다.Generally, a ship's rudder has one rudder arranged in series behind the helical thruster, as shown in FIG. 4, and the ship's hull is enlarged in front of the thruster, leading to a sharp streamline shrinkage rate. Generates. In addition, in the magnetic port side, the inflow angle of the fluid flowing into the helical propeller is large, which causes a reduction in thrust, and at the same time, the decrease in efficiency leads to a decrease in the overall transmission efficiency due to the propeller's own characteristics, which increases the required horsepower for a certain ship speed. It smoothly flows along the surface to move the fluid separation point to the rear of the stern to reduce the viscous resistance of the hull and to reduce the inflow angle of the fluid flowing into the propeller to increase the propulsion efficiency by smoothly flowing the fluid into the propeller. There is a need for a ship rudder arranged in parallel with a spiral propeller.

종래에는 나선형 추진기 후방에 타를 직렬로 배치함으로서 추진기 전방에 선체가 비대하여 유선 축소율이 급격하고, 유체의 박리현상이 상대적으로 일찍 발생함으로써 점성 저항이 증가하며, 나선형 추진기로 유입되는 유체의 유입각이 커져 추력이 감소되어 전체 전달효율의 감소로 이어져 소요 마력이 증가하는 문제점이 있었다.Conventionally, by arranging the rudder in series behind the helical propeller, the hull is enlarged in front of the propeller to increase the contraction rate of the wire and increase the viscous resistance by relatively early separation of the fluid. This increased thrust is reduced, leading to a decrease in the overall transmission efficiency, there was a problem that the required horsepower increases.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 안출되는 것으로, 제한된 선박의 길이 이내에서 가능한 나선형 추진기를 선미 끝단으로 이동시키고, 상기 나선형 추진기 좌, 우측에 타를 병렬로 배치하여 수선을 연장시켜 추진 성능을 극대화하고, 선박의 전체 길이 대비 잠수된 선체의 측면적을 넓힘으로써 조정성능을 위한 기본적 선형 포텐셜을 높일 수 있는 나선형 추진기와 병렬로 배치되는 선박용 타를 제공하는 것을 목적으로 한다.The present invention is devised to solve the conventional problems as described above, by moving the helical propeller to the stern end possible within the limited length of the ship, by arranging the rudder to the left and right of the spiral propeller in parallel to extend the waterline It is an object of the present invention to provide a ship rudder arranged in parallel with a helical thruster that can maximize propulsion performance and increase the basic linear potential for coordination by widening the lateral area of the submerged hull relative to the overall length of the ship.

본 발명의 구성에 대해 첨부도면과 연계하여 설명하면 다음과 같다.Referring to the configuration of the present invention in conjunction with the accompanying drawings as follows.

도 1 은 본 발명에 따른 타 및 추진기의 병렬형 배치도를 도시한 것이고, 도 2 는 본 발명의 쌍축선에서의 타 및 추진기의 병렬형 배치도를 도시한 것이며, 도 4 는 종래의 타 및 추진기의 배치도를 도시한 것으로서, 그 구성은 나선형 추진기 (2)를 최대한 선미 끝단으로 배치하고, 상기 선미 끝단에 배치된 나선형 추진기(2) 좌, 우측에 타(1)를 상기 나선형 추진기(2)와 병렬로 배치한다.Figure 1 shows a parallel arrangement of the rudder and the propeller according to the present invention, Figure 2 shows a parallel arrangement of the rudder and propeller in the twin axis of the present invention, Figure 4 is a conventional rudder and propeller As the layout is shown, the configuration is to arrange the helical thruster 2 at the stern end as much as possible, and parallel to the helical thruster 2 to the left and right of the helical thruster 2 disposed at the stern end. Post it.

상기 나선형 추진기(2)가 두개 장착된 쌍축선에서는 상기 나선형 추진기(2) 사이에 한 개의 타(1)를 배치하고, 각각의 나선형 추진기(2) 일측에 타(1)를 하나씩 배치하여 세 개의 타(1)가 상기 두개의 나선형 추진기(2)와 병렬 배치되도록 한다.In the biaxial line in which the spiral propellers 2 are mounted, one rudder 1 is disposed between the helical propellers 2 and three rudders are arranged one by one on each side of each spiral propeller 2. The rudder 1 is arranged in parallel with the two helical thrusters 2.

상기와 같은 구성을 참조하여 본 발명의 작용을 설명하면 다음과 같다.Referring to the configuration as described above the operation of the present invention.

도 3 은 나선형 추진기(2')와 직렬로 배치된 타(1')와 상기한 타(1')의 배치로 인한 유체의 박리점(3')과 유체의 유입각(4') 및 유입 유체(5)와 선체 형상(6')은 점선으로 나타내며, 본 발명에 의한 나선형 추진기(2)와 병렬로 배치된 타(1)와 상기와 같이 병렬로 배치된 타(1)에 의한 유체의 박리점(3)과 유체의 유입각(4) 및 유입 유체(5)와 선체 형상(6)은 실선으로 나타내어 타의 배치와 기능을 비교한 것이다.FIG. 3 shows the inlet 4 'and the inlet angle 4' and the inlet angle of the fluid due to the arrangement of the rudder 1 'arranged in series with the helical thruster 2' and the rudder 1 'described above. The fluid 5 and the hull shape 6 ′ are indicated by dotted lines, and the fluid 1 by the rudder 1 arranged in parallel with the helical thruster 2 according to the invention and the rudder 1 arranged in parallel as described above. The peeling point 3, the inflow angle 4 of the fluid, the inflow fluid 5, and the hull shape 6 are shown by the solid line, and the arrangement and function of the other are compared.

점선으로 나타낸 나선형 추진기(2') 후방에 직렬로 타(1')가 배치된 위치까지 나선형 추진기(2)를 이동시켜 배치하고, 상기 나선형 추진기(2) 좌, 우측에 타(1)를 배치함으로서 직렬 배치시의 선체의 형상(6')과 병렬 배치시의 선체의 형상(6)을 살펴보면 직렬 배치시의 선체 형상(6') 보다 수선을 더 연장시킬 수 있는 유선형의 선체 형상(6)을 얻을 수 있다.The helical propeller 2 is moved and arranged to the position where the rudder 1 'is arranged in series behind the helical thruster 2' indicated by the dotted line, and the rudder 1 is disposed on the left and right sides of the helical thruster 2. By looking at the shape 6 'of the hull in series and the shape 6 of the hull in parallel, the streamlined hull shape 6 can extend the waterline more than the hull shape 6' in the serial arrangement. Can be obtained.

즉, 상기 선체 형상(6)이 각도가 완만한 유선형의 형태로 이루어져 유체의 유입각(4)이 작아서 유입 유체(5)가 선체 표면을 따라 원활히 흐를 수 있으나, 타 (1')의 직렬 배치시에는 유체의 유입각(4')이 상대적으로 병렬 배치시의 유체의 유입각(4) 보다 커서 추력 감소의 원인이 됨과 동시에 추진기(2')의 효율을 저하시킨다.That is, since the hull shape 6 has a streamlined shape with a gentle angle, the inflow angle 4 of the fluid is small so that the inflow fluid 5 can flow smoothly along the surface of the hull, but the arrangement of the other 1 'is in series. In this case, the inflow angle 4 'of the fluid is relatively larger than the inflow angle 4 of the fluid in parallel arrangement, which causes a reduction in thrust and at the same time lowers the efficiency of the propeller 2'.

또한, 직렬 배치시의 유체의 박리점(3') 대비 병렬 배치시의 유체의 박리점 (3)이 직렬 배치시보다 선미 후방으로 이동되어 선체의 점성저항이 감소하며, 추진기(2) 전방의 선체 형상(6)의 각도가 완만하여 직렬 배치시의 유체의 유입각(4') 대비 병렬 배치시의 유체의 유입각(4)이 감소하여 유체의 나선형 추진기(2)로의 유입을 원활하게 함으로써 추진효율이 증가됨과 동시에 전체 전달효율이 증가되어 선속을 위한 소요 마력이 감소하게 된다.In addition, the peeling point 3 of the fluid in parallel arrangement with respect to the peeling point 3 'of the fluid in series arrangement is moved to the stern rear than in the case of series arrangement, and the viscosity resistance of the hull is reduced, The angle of the hull shape 6 is gentle so that the inflow angle 4 of the fluid in parallel arrangement decreases compared to the inflow angle 4 'of the fluid in series arrangement, so that the fluid flows smoothly into the spiral propeller 2. At the same time as the propulsion efficiency is increased, the overall transmission efficiency is increased, which reduces the horsepower required for ship speed.
