Description

Wing sail structure with top end plate The present invention relates to a wing sail structure having a top end plate formed thereon. Ships operating at sea rely heavily on fossil fuels, to the extent that the shipping industry's annual carbon emissions are estimated to exceed 1 billion tons. Accordingly, the International Maritime Organization (IMO) has set a goal to reduce greenhouse gas emissions by at least 20% by 2030 and at least 70% by 2040, and has declared the realization of carbon neutrality in the shipping industry by 2050. In order to respond to stricter marine environmental regulations and reduce the use of fossil fuels, the shipping industry is attempting to improve the propulsion of ships by using wind power by equipping them with wind-assisted devices such as wing sails and rotor sails. When wind is applied to a wing sail, which is manufactured in the shape of an airfoil and mounted on a ship, thrust is generated in the direction of hull propulsion and a side force is generated in the direction of the hull's side that hinders the maintenance of the course. At this time, in order to generate maximum thrust, the wing sail is rotated to have an appropriate angle of attack (AoA). Currently, various attempts are being made to modify the cross-sectional shape of the wing sail body in order to improve the efficiency of the wing sail. However, there is a limitation in that modifying only the cross-sectional shape of the wing sail body does not improve the thrust enhancement effect of the ship using wind to a satisfactory level. The matters described in the technical background section of this invention are for the purpose of understanding the background of the invention and cannot be concluded as prior art already known to a person with ordinary knowledge in the field to which this technology belongs. FIG. 1 is a drawing illustrating a ship equipped with a wing sail according to the prior art. FIG. 2 is a drawing illustrating the shape of a wing sail body and tip vortex generation according to the prior art. FIG. 3 is a drawing showing the shape of a wing sail structure according to an embodiment of the present invention. FIG. 4 is a drawing illustrating the shape of a wing sail structure viewed from below according to an embodiment of the present invention. FIG. 5 is a drawing illustrating the formation structure of a wing sail structure according to one embodiment of the present invention. The present invention is capable of various modifications and may have various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the invention to specific embodiments, and it should be understood that the invention includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention. Embodiments of the present invention will be described below with reference to the accompanying drawings. In the accompanying drawings, identical components are given the same reference numerals, and in the description of the embodiments, identical or corresponding components may be briefly described or redundant descriptions may be omitted. In the drawings, each component may be depicted in an exaggerated size for convenience of explanation and understanding, and it is obvious that the present invention is not limited to the size and proportion of the components depicted in the drawings. FIG. 1 is a drawing illustrating a ship equipped with a wing sail according to the prior art, and FIG. 2 is a drawing illustrating the shape of the wing sail body and the generation of a tip vortex according to the prior art. Referring to FIG. 1, a ship (10) is equipped with a plurality of wing sails (20) as wind power assist devices. A wing sail (20) may include a wing sail body (22) and a rotating support member (24) that fixes and supports the wing sail body (22) and rotates it. In order to increase the thrust of the vessel (10) by utilizing the wind blowing from the side, the rotating support (24) is driven to rotate the wing sail body (22) in an appropriate direction. The operation of the rotating support (24) can be controlled by a controller provided on the vessel (10) or the wing sail (20). When the wing sail body (22) is rotated in response to wind blowing from the side of the vessel (10), thrust is applied to the wing sail body (22) in the direction of travel of the vessel (10), and a side force, which is a factor hindering the maintenance of the course, is applied in the lateral direction of the vessel (10). Generally, in order to maximize thrust on the vessel (10), the controller controls the rotation operation of the wing sail body (22) so that the angle of attack (AoA) has maximum lift and minimum drag. That is, wind blowing from the side of the vessel (10) flows along both sides of the rotating wing sail body (22). At this time, thrust is generated in the direction of travel of th
