Description

풍력발전기 날개의 저항 시험용 알루미늄 선박{Aluminium boat for testing of wind resist by wind turbine blade}Aluminum boat for testing of wind resist by wind turbine blade

알루미늄 선체 보트는 다른 종류의 선박과 비교되는 특징이 있다. Aluminum hull boats are characterized by comparison with other types of ships.

1) FRP선체 선박에 비해 상대적으로 고가이나 우수한 내구성 및 재활용이 가능하다.1) It is relatively expensive compared to FRP hull ships, but excellent durability and recycling are possible.

: FRP선박 대비 상대적으로 고가이나, 강도 및 내구성이 우수하여 안전하고, 폐선 시 재활이 가능하다는 장점이 있다.: It is relatively expensive compared to FRP ships, but it has the advantages of being safe due to its excellent strength and durability, and that it can be rehabilitated when it is decommissioned.

2) FRP선체 선박에 비해 작은 동력으로 운용이 가능하여 에너지 효율이 높다.2) Compared to FRP hull ships, it is possible to operate with less power, so energy efficiency is high.

: 16ft급 선박의 경우 FRP선체 선박은 90마력대가 적용되는 반면, 알루미늄 선체 선박은 50-60마력이 일반적으로 적용되며, 상대적으로 작은 동력으로 운용이 가능해 에너지 효율이 높다는 장점이 있다.: In the case of 16ft class ships, FRP hull ships use 90 horsepower, whereas aluminum hull ships generally use 50-60 horsepower.

3) 크기에 비해 공간이 넓다.3) It is spacious for its size.

: 재질의 특성으로 인하여 FRP선체 선박 대비 동일 길이라면 20-30% 정도 공간이 넓다. 이는 공간 활용을 극대화해야 하는 선박의 특성에서 중요한 장점이 된다.: Due to the characteristics of the material, the space is 20-30% wider than that of the FRP hull ship if it is the same length. This is an important advantage in terms of the characteristics of a ship that must maximize space utilization.

4) 무게가 가볍다.4) Light weight.

: 무게가 가볍기 때문에 에너지 소모가 적고, 민첩하다. FRP선체 선박은 진입이 불가능한 영역도 알루미늄 선체선박은 거침없이 진입이 가능하다는 장점이 있다.: Light weight, low energy consumption and agility. FRP hull ships have the advantage of being able to enter areas where it is impossible for aluminum hull ships to enter without hesitation.

5) 내구성이 좋다.5) Good durability.

: FRP선체 선박의 경우 운행 중 사고로 보트가 험프 등에 접촉 사고를 냈을 경우 파손이 되어 폐선을 해야 하는 경우가 발생하지만 알루미늄은 찌그러지는 정도로 피해가 적다.: In the case of FRP hull ships, if the boat crashes into a hump due to an accident during operation, it may be damaged and have to be discontinued, but the damage is small enough to be crushed by aluminum.

선박이 추진하는 데 필요한 에너지의 사용량을 줄이기 위한 다양한 방법들이 고안되어 사용되고 있으며, 화석연료의 고갈 및 지구온난화 문제에 대응하기 위한 다양한 연구와 시도가 이뤄지고 있는 실정이다.Various methods have been devised and used to reduce the amount of energy required to propel a ship, and various studies and attempts are being made to cope with the depletion of fossil fuels and global warming.

선박이 추진하는 데 영향을 주는 요소들은 연료, 선체의 재질, 선박의 구조 및 형상, 운용 시스템 등에 의해 결정되며, 해수와의 마찰 저항 및 공기의 저항을 주요 변수로 인식하여 다루고 있다.Factors that affect the propulsion of a ship are determined by fuel, hull material, structure and shape of the ship, and operating system, and are treated by recognizing frictional resistance with seawater and air resistance as major variables.

선박의 연료 변경에 따른 선형의 설계 변경 및 구조변경이 필수적이기 때문에 연료의 변경은 선박의 미래를 예측하는데 지대한 영향을 미치는 요소이다. 전기추진선의 사용이 늘고 있는 점은 이러한 요소들이 반영된 결과라고 할 것이다. Since it is essential to change the design and structure of the ship according to the fuel change of the ship, the change of fuel is a factor that has a great influence on predicting the future of the ship. The increase in the use of electric propulsion lines is a result of these factors being reflected.

선박의 저항을 낮추기 위한 노력들의 대표적인 사례들로는 선수 벌브, 유선형의 선형설계, 선체 표면의 나노구조물 형성, 선측의 유체 통로 설치, 프로펠러의 표면 설계, 선미 유동저항 감소 설계 등의 선체 구조와 관련된 분야가 주로 다뤄지며, 저항감소용 도료 사용, 선박의 재질 변경 등의 사항을 고려하여 변경하는 사례들도 많다. Representative examples of efforts to lower the resistance of a ship are the fields related to the hull structure such as bow bulb, streamlined linear design, formation of nanostructures on the hull surface, installation of fluid passages on the side of the ship, surface design of propellers, and design to reduce stern flow resistance. It is mainly dealt with, and there are many cases of change in consideration of the use of paint for resistance reduction and change of the material of the ship.

따라서, 알루미늄 선박에 전기추진시스템을 갖추는 것은 미래의 선박시장에서 차지하는 비중이 높아질 가능성이 크다고 할 것이다.Therefore, equipping an aluminum ship with an electric propulsion system is likely to increase its share in the future ship market.

레져 보트 등의 소형 선박에 적용하는 전기추진용 선외기의 일반적인 적용 상황은 다음과 같다.The general application situation of electric propulsion outboard motors applied to small ships such as leisure boats is as follows.

- 전기추진 선외기의 주요 구성은 크게 상부에 파워 헤드(power head), 중앙부(mid section) 및 하부에 로워 유닛(lower unit)으로 구성된다.- The main configuration of the electric propulsion outboard machine is largely composed of a power head in the upper part, a mid section, and a lower unit in the lower part.

- 상부의 파워 헤드(power head)는 주 동력원인 전기모터 구성품이 위치하고 있으며, 중앙부(mid section)의 주 기능은 전기모터의 동력을 하부인 로워 유닛으로 전달하면서 선외기를 선박의 선미에 고정시키는 역할을 하게 되며 이에 관계된 동력전달 샤프트 등이 위치한다.- In the upper power head, the main power source, the electric motor component, is located, and the main function of the mid section is to transfer the electric motor power to the lower unit, which is the lower part, and to fix the outboard unit to the stern of the ship. and the related power transmission shaft is located.

- 전기추진 선외기의 주요 구성부에 해당되는 로워 유닛(lower unit)의 경우 전기 모터로부터 전달받은 동력을 추진력으로 전환하는 기능 및 이를 위해 프로펠러, 기어박스 등이 위치하고 있다.- In the case of the lower unit, which corresponds to the main component of the electric propulsion outboard, the function of converting the power received from the electric motor into propulsion, and for this purpose, a propeller, a gearbox, etc. are located.

- 전기추진 선외기가 장착된 알루미늄 선박의 경우 전진, 정지, 역전 등 조작성이 매우 우수하여 양식장 관리어선, 유어선 등 소형 어선에 적합하며, 특히, 후진에도 전진과 같은 힘을 신속히 낼 수 있어서 도서지방의 제한된 해역에서 운전이 용이할 것으로 전망한다.- In the case of an aluminum vessel equipped with an electric propulsion outboard, it has excellent maneuverability such as moving forward, stopping, and reversing, making it suitable for small fishing vessels such as farm management fishing boats and fishing boats. It is expected to be easy to drive in the limited waters of

알루미늄 선체 선박은 알루미늄의 재질 특성상 선체의 하중을 줄일 수 있기 때문에 엔진의 추진효율도 좋아져서 선박의 에너지 절감에 기여하는 것은 당연한 것이다. 다만, 전기추진 선박의 경우에 축전지의 축전용량의 한계 등으로 인해서 선박운용의 제한이 따르는 것이 사실이다. 따라서, 육상에서 충전한 축전지를 선박에서 사용하는 방식으로는 선박의 운용이 자유롭지 못한 문제점이 있다. Since aluminum hull ships can reduce the load on the hull due to the characteristics of the material of aluminum, it is natural that the engine's propulsion efficiency also improves, thereby contributing to the energy saving of the ship. However, in the case of electric powered ships, it is true that there are restrictions on the operation of ships due to the limitation of the storage capacity of the storage battery. Therefore, there is a problem in that the operation of the ship is not free in the method of using the storage battery charged on land in the ship.

또한, 축전에 의한 전기사용은 에너지 효율의 측면에서 볼 때, 에너지 사용량을 증가시키는 문제점이 상존한다. 원유의 역률이 0.99 인데 비해서 전기의 역률은 0.25이기 때문에 동일한 힘을 얻기 위해서는 전력발생량을 대폭 증가해야 하는 이율배반적인 상황에 마주하게 되는 것이다. In addition, in terms of energy efficiency, electricity use by storage always has a problem of increasing energy consumption. Since the power factor of crude oil is 0.99, the power factor of electricity is 0.25, so in order to obtain the same power, the amount of power generated must be greatly increased.

본 발명은 이러한 문제점을 해결하고자 선박 추진시의 에너지 효율을 높이는 방법을 찾아본 결과 공기저항을 줄이는 방법에 대해서 착안하게 되었으며, 풍력발전 날개를 설치하는 것이 가장 효과적인 방안이라는 점을 도출하였다. 따라서, 풍력발전기 날개의 구조 형상 및 설치 위치 등의 요소들을 시험하는 선박이 필수적이다.In order to solve this problem, the present invention came up with a method for reducing air resistance as a result of finding a method for increasing energy efficiency during ship propulsion, and it was derived that installing wind turbine blades is the most effective method. Therefore, it is essential to have a ship that tests elements such as the structural shape and installation location of the wind turbine blades.

일반적으로 선체에 작용하는 유체의 영향에 대한 다양한 연구가 진행되어 왔으며, 에너지 밀도가 높은 물과 선체의 관련성에 대한 연구가 집중되었던 것이 사실이다. 그 결과로 선수 벌브, 유선형 선형설계, 선체 표면의 나노구조물, 선측의 유체 통로, 프로펠러의 표면 설계, 선미 유동저항 감소 설계 등의 선체 구조와 관련된 분야가 주로 다뤄지며, 저항감소용 도료 사용 등의 적용 사례들이 다수 존재한다. 다만, 공기저항과 선체의 연관성에 대한 연구는 지지부진한 실정이라고 할 수 있다.In general, various studies have been conducted on the effects of fluids acting on the hull, and it is true that studies on the relationship between water with high energy density and the hull have been focused. As a result, the fields related to the hull structure such as bow bulb, streamlined linear design, nanostructure on the hull surface, fluid passage on the side of the ship, propeller surface design, and stern flow resistance reduction design are mainly dealt with, and the application of paint for reducing resistance Many examples exist. However, it can be said that the research on the relationship between air resistance and the hull is sluggish.

본 발명은 공기저항을 줄여서 선박의 추진효율을 줄이기 위한 방법으로 선체에서 공기저항을 가장 많이 받는 곳을 선택하여 풍력발전기 날개를 설치하여 공기저항의 감소 여부를 알아보는 것이다. 이때, 기존의 풍력발전기 날개를 설치하는 것은 제외한다. 기존의 풍력발전기 날개의 단면적은 최대 12%에 불과하여 공기저항을 줄이는 효과를 기대할 수 없기 때문이다. 따라서, 풍력발전기의 단면적이 커서 공기의 저항이 선체에 직접 접촉하지 않도록 하는 것이 본 발명의 주요 목적이며, 공기저항의 여부를 시험하는 핵심 요소이다.The present invention is a method for reducing the propulsion efficiency of a ship by reducing the air resistance, by selecting a place that receives the most air resistance in the hull and installing the wind turbine blades to find out whether the air resistance is reduced. At this time, the installation of the existing wind turbine blades is excluded. This is because the cross-sectional area of the existing wind turbine blades is only 12%, so the effect of reducing air resistance cannot be expected. Therefore, the main object of the present invention is to prevent the air resistance from directly contacting the hull due to the large cross-sectional area of the wind turbine, and it is a key element for testing the air resistance.

공기의 저항을 받는 선체에 풍력발전기 날개를 설치하여서 공기 저항의 발생특성을 연구함으로써 전기추진선박의 에너지 저감 효과를 시험하는 선박의 필요성을 확보하는 효과가 있다.It has the effect of securing the need for a ship that tests the energy reduction effect of an electric powered ship by installing a wind turbine blade on the hull that receives air resistance and studying the characteristics of air resistance.
