Description

Rotor sail The present invention relates to a rotor sail. While propulsion systems on ships typically consist of propellers rotated by engines, the demand for eco-friendly ship designs has recently been increasing due to the expansion of greenhouse gas emission regulation zones. A rotor sail, or magnus rotor, refers to a cylindrical structure installed to rotate on a ship's deck; rotor sails can reduce fuel consumption by generating additional thrust through the magnus effect. Since these rotor sails are positioned on the ship's deck and are vulnerable to lightning strikes during navigation, lightning countermeasures for rotor sails are being studied. FIG. 1 is a cross-sectional view schematically illustrating a rotor sail according to one embodiment of the present invention. Figure 2 is a cross-sectional view showing a part of the rotor sail illustrated in Figure 1. Figure 3 is a schematic diagram showing the rotor sail of Figure 1 viewed from above. Figure 4 is a cross-sectional view of the rotor sail of Figure 3 cut along the B-B' direction. Figure 5 is a cross-sectional view of the rotor sail of Figure 3 cut along the C-C' direction. Figure 6 is an enlarged view of area A of the rotor sail in Figure 2. Figure 7 is a cross-sectional view of the rotor sail of Figure 6 cut in the D-D' direction. FIG. 8 is a schematic diagram showing a top view of a rotor sail according to another embodiment of the present invention. Hereinafter, the following embodiments will be described in detail with reference to the attached drawings. When describing with reference to the drawings, identical or corresponding components are given the same reference numerals, and redundant descriptions thereof will be omitted. Since the embodiments are capable of various modifications, specific embodiments are illustrated in the drawings and described in detail in the detailed description. The effects and features of the embodiments and the methods for achieving them will become clear by referring to the details described below in conjunction with the drawings. However, the embodiments are not limited to those disclosed below and can be implemented in various forms. Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. When describing with reference to the drawings, identical or corresponding components are given the same reference numerals, and redundant descriptions thereof will be omitted. In the following embodiments, terms such as first, second, etc. are used not in a limiting sense, but for the purpose of distinguishing one component from another. In the following embodiments, singular expressions include plural expressions unless the context clearly indicates otherwise. In the following embodiments, terms such as "include" or "have" mean that the features or components described in the specification are present, and do not preclude the possibility that one or more other features or components may be added. Where an embodiment can be implemented differently, a specific process sequence may be performed differently from the order described. For example, two processes described consecutively may be performed substantially simultaneously or proceed in the reverse order of the description. In the drawings, the size of components may be exaggerated or reduced for convenience of explanation. For example, the size and thickness of each component shown in the drawings are depicted arbitrarily for convenience of explanation, so the following embodiments are not necessarily limited to those illustrated. In the following, a ship may be a large vessel such as an oil tanker, LNG carrier, LPG carrier, container ship, car carrier, bulk carrier, or mineral carrier that carries a large amount of minerals, crude oil, natural gas, or thousands of containers in its cargo hold and sails the ocean, but is not limited thereto and may include all types of ships and offshore structures of various forms. In the embodiments of the present invention described below, the vessel may selectively or in combination use power obtained by an engine and wind power obtained by a wind power assist device as propulsion energy for the vessel. When the engine and the wind power assist device are used in combination, the power obtained by the engine may be used as the primary propulsion energy for the vessel, and the wind power may be used as auxiliary propulsion energy.
