Description
Hybrid Rotor Sail System and Ship The present invention relates to a hybrid rotor sail system and a vessel. Propellers rotated by engines are commonly used as propellers on ships, but recently, with the expansion of greenhouse gas emission regulation zones, there is an increasing demand for eco-friendly ship designs. A rotor sail or magnus rotor refers to a cylindrical structure installed to rotate on the deck of a ship, and the rotor sail can reduce fuel consumption by generating additional thrust using the magnus effect. The above rotor sail is generally composed of a fixed body fixed to the deck of a ship, a rotor body provided in a cylindrical shape surrounding the fixed body and rotatably fixed to the fixed body, and a driving unit that rotates the rotor body. Since the effectiveness of rotor sails can vary depending on wind direction or speed, they are not used unless conditions are right. As rotor sail systems occupy a large volume on vessels, there is a need to expand their applications. FIG. 1 is a drawing illustrating a ship equipped with a hybrid rotor sail system according to one embodiment of the present invention. FIG. 2 is a drawing illustrating a hybrid rotor sail system according to one embodiment of the present invention. FIGS. 3 to 6 are drawings illustrating a method for opening and closing a wing of a hybrid rotor sail system according to an embodiment of the present invention. FIGS. 7 and 8 are top views of a hybrid rotor sail system according to another embodiment of the present invention. Hereinafter, embodiments disclosed in this specification will be described in detail with reference to the attached drawings. Identical or similar components regardless of drawing symbols will be assigned the same reference number, and redundant descriptions thereof will be omitted. The suffixes "module" and "part" used for components in the following description are assigned or used interchangeably solely for the ease of drafting the specification and do not inherently possess distinct meanings or roles. Furthermore, in describing embodiments disclosed in this specification, if it is determined that a detailed description of related prior art could obscure the essence of the embodiments disclosed in this specification, such detailed description will be omitted. Additionally, the attached drawings are intended only to facilitate understanding of the embodiments disclosed in this specification; the technical concept disclosed in this specification is not limited by the attached drawings, and it should be understood that they include all modifications, equivalents, and substitutions that fall within the spirit and technical scope of the present invention. Terms including ordinal numbers, such as first, second, etc., may be used to describe various components, but said components are not limited by said terms. These terms are used solely for the purpose of distinguishing one component from another. When it is stated that one component is "connected" or "connected" to another component, it should be understood that while it may be directly connected or connected to that other component, there may also be other components in between. On the other hand, when it is stated that one component is "directly connected" or "directly connected" to another component, it should be understood that there are no other components in between. A singular expression includes a plural expression unless the context clearly indicates otherwise. In this application, terms such as “comprising” or “having” are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. FIG. 1 is a drawing illustrating a vessel (100) equipped with a hybrid rotor sail system (160) according to one embodiment of the present invention. The vessel (100) illustrated in FIG. 1 may include a hull (110), a propulsion unit that generates propulsion force necessary for the movement of the hull (110), a steering unit that controls the direction of movement of the hull (110), and a rotor sail (R) provided on the deck (111) of the hull (110). The above rotor sail (R) is a means of generating propulsion for the hull (110) using the Magnus Effect, which is a phenomenon in which, when a rotating object moves in air or fluid, the object deviates from its path of movement and moves in a curve due to the asymmetric pressure distribution that occurs around the object. One side where the rotation direction of the rotor sail (R) and the fluid flow direction are aligned has a lower air density, and the other side where the rotation direction of the rotor sail and the fluid flow direction are opposite has a higher air density, so a force is generated from the other side toward the one side, and by utilizing this,
