[0021] It should be noted that when assigning reference numbers to the components of each drawing in the specification, identical components are assigned the same number whenever possible, even if they are shown in different drawings. Furthermore, in describing the present invention, detailed descriptions of related prior art are omitted if it is determined that such detailed descriptions could unnecessarily obscure the essence of the invention.

[0022] For reference, the present invention includes a vessel equipped with a liquefied gas storage tank as described below. The vessel may be at least a vessel that uses liquefied gas as propulsion fuel / power generation fuel, and the concept includes gas carriers, merchant vessels that transport cargo or people other than gas, FSRUs, FPSOs, bunkering vessels, offshore plants, etc.

[0024] FIG. 1 is a side view of a ship (100) including a wind propulsion system (1) according to the present invention.

[0025] Referring to FIG. 1, at least one wind propulsion system (1) according to one embodiment of the present invention may be provided on the deck (S) of a ship (100). The wind propulsion system (1) can help propel the ship (100) by directly rotating using power and converting wind into propulsion force.

[0026] The wind propulsion system (1) is formed vertically with respect to the deck (S) and multiple wind propulsion systems (1) can be arranged side by side. Multiple wind propulsion systems (1) can be positioned in front of the cabin and can be spaced apart at regular intervals so that the bow can be seen from the cabin.

[0027] In FIG. 1, the ship (100) is depicted as not having cargo loaded on the deck (S), but depending on the type of fuel tank, the fuel tank may be exposed on the deck (S) and cargo such as containers may be loaded on the deck (S).

[0028] The wind propulsion system (1) can be placed on the deck (S) of the ship (100) together with the cargo, and can be placed apart from the cargo by considering the fluid flow generated through the rotation of the wind propulsion system (1) since it provides propulsion to the ship (100) using the Magnus effect.

[0029] The wind propulsion system (1) can be placed on the deck (S) taking into account weight balance and movements such as rolling and pitching of the ship (100), and can be placed symmetrically with respect to the centerline of the width of the ship (100).

[0031] FIG. 2 is a conceptual diagram of a wind propulsion system (1) according to the present invention.

[0032] Referring to FIG. 2, the wind propulsion system (1) may include a support member (10), a stator (20), a rotor (30), an end plate (40), and a guide member (70).

[0033] The support member (10) can be formed such that its lower surface contacts the deck (S) and its upper surface contacts the stator (20). The support member (10) is formed on the deck (S) of the ship (100) and can be fixed in position on the deck (S) by being joined to the deck (S) through welding or bolting.

[0034] The support member (10) protrudes at a certain height on the deck (S) and can support the stator (20) and rotor (30) placed on the upper surface. The support member (10) is formed in the shape of a circular or polygonal column and can be formed to simply support the stator (20) and rotor (30) without a part being open.

[0035] In another embodiment of the present invention, the support member (10) may include a bridge shape, and the space between the bridge shapes may be open, allowing fluid flow through the open portion and enabling movement of users, thereby facilitating maintenance.

[0036] The stator (20) is vertically connected to the support member (10) and may include a drive member (60) inside. The stator (20) may be formed at a height lower than that of the rotor (30) to support the interior of the rotor (30). The outer surface of the stator (20) may be formed through a plurality of assemblies or may be formed as a truss structure with an open outer surface.

[0037] A drive unit (60) is installed on one side of the stator (20), and the other side, opposite to the one side, can be positioned on a support unit (14). A guide bearing can be formed around the stator (20), and the guide bearing can be formed adjacent to the other side of the stator (20).

[0038] The stator (20) may be formed in a cylindrical shape to resemble the rotor (30) or may be formed in a polygonal prism shape for ease of manufacturing, so the external shape of the stator (20) is not limited to a cylinder.

[0039] The driving unit (60) can be coupled with the disk (50) of the rotor (30) and can be positioned on one side of the stator (20).

[0040] The drive unit (60) generates power on its own to enable the disk (50) and the rotor (30) to rotate. When the disk (50) rotates by the drive unit (60), the rotor (30) connected to the disk (50) can rotate. The drive unit (60) can provide the generated power to the rotor (30) through the disk (50) to enable the rotation of the rotor (30).

[0041] The drive unit (60) may include a motor and a VFD (variable frequency drive) to control the initiation of rotation, rotational speed, and direction of the rotor (30). The rotational speed and direction of the rotor (30) may vary depending on the operation method of the drive unit (60).

[0042] In FIG. 2, the driving unit (60) is shown as being densely arranged on one side of the stator (20), but it may be separated into multiple layers according to the height direction of the stator (20).

[0043] The rotor (30) can be rotatably coupled to the stator (20).

[0044] The rotor (30) is formed to surround the outer side of the stator (20) and may have a larger cross-sectional area than the stator (20). The rotor (30) rotates around the stator (20) as an axis and can assist in the propulsion of the vessel (100) by utilizing the Magnus effect.

[0045] The rotor (30) is formed with an open upper and lower section, and an end plate (40) is installed on the upper section, and a stator (20) can be inserted through the open lower section.

[0046] The rotor (30) has a hollow interior and a stator (20) is positioned inside it, and can be connected to the stator (20) through a disk (50). The rotor (30) is rotatable relative to the stator (20), and whether it rotates can be determined by the operation of the drive unit (60).

[0047] The stator (20) can act as a support for the rotor (30), and the rotor (30) can rotate relative to the stator (20) to change the flow of fluid.

[0048] The rotor (30) may be spaced apart from the support member (10) so that it can rotate relative to the stator (20) and the support member (10). A guide member (70) is formed in the area of ​​the rotor (30) adjacent to the support member (10) to assist in the rotation of the rotor (30).

[0049] The end plate (40) can be coupled to the open upper portion of the rotor (30) and may have a cross-sectional area larger than that of the rotor (30). Generally, the end plate (40) may be formed to be twice the diameter of the rotor (30), but is not limited to specific dimensions if the diameter of the end plate (40) is formed to be larger than the diameter of the rotor (30).

[0050] The end plate (40) can cap the upper part of the rotor (30) to prevent air inside the rotor (30) from flowing through the upper part.

[0051] The disk (50) may be formed across the interior of the rotor (30) and may be formed perpendicular to the height direction of the rotor (30). The disk (50) may have a shape corresponding to the inner surface of the rotor (30), for example, in the shape of a disc, and may be connected to the inner surface of the rotor (30).

[0052] The disk (50) can be positioned at a height higher than that of the stator (20) inserted into the rotor (30) and connected to the upper part of the stator (20). The disk (50) can be connected to a drive unit (60) installed on the stator (20) and can rotate by receiving power from the drive unit (60).

[0053] The disk (50) rotates by the power of the drive unit (60), and the rotor (30) connected to the disk (50) rotates together, thereby allowing the power of the drive unit (60) to be transmitted to the rotor (30). The disk (50) and the rotor (30) can be rotated by the drive unit (60) around the stator (20) as an axis.

[0054] The guide section (70) may include a guide bearing (not shown) and a guide rail (not shown).

[0055] A guide bearing can be formed adjacent to the other side around the stator (20) and positioned close to the support member (10). The guide bearing engages with the guide rail of the rotor (30) to form a guide member (70) and can guide the rotation of the rotor (30).

[0056] The guide bearing is formed to be rotatable with respect to the stator (20) and can guide the rotor (30) which rotates by the power of the drive unit (60). The guide bearing is formed to suppress lateral movement when the rotor (30) rotates, thereby minimizing the shaking of the rotor (30).

[0057] The guide bearing can engage with a guide rail formed on the inside or inner surface of the rotor (30) around the stator (20).

[0058] The guide rail is formed inside the rotor (30) and can be formed in a ring shape along the inner surface of the rotor (30). The guide rail is formed at a position corresponding to the guide bearing of the stator (20) so that it can be positioned to come into contact with the guide bearing when the stator (20) and the rotor (30) are combined.

[0059] The guide bearing can rotate relative to the stator (20) while in contact with the guide rail, thereby rotating on the guide rail. The guide rail can assist in the rotation of the guide bearing.

[0060] The guide bearing can rotate relative to the stator (20) on the guide rail to correspond to the rotation of the rotor (30). When the rotor (30) rotates, the guide bearing can rotate on the guide rail.

[0061] The guide rail and guide bearing can guide the rotor (30) rotating around the stator (20) as an axis and can suppress the lateral movement of the rotor (30).

[0062] Guide bearings may be placed in the stator (20) and guide rails may be placed in the rotor (30), but the arrangement of guide bearings and guide rails may be interchanged.

[0063] For example, a guide bearing may be placed on the rotor (30) and a guide rail may be placed on the stator (20), so that the arrangement of the guide bearing and the guide rail is not limited as long as they are formed at corresponding heights.

[0065] FIG. 3 is a cross-sectional view of a wind propulsion system (1) according to one embodiment of the present invention.

[0066] Compared to FIG. 2, FIG. 3 may further include a duct (80) and a ventilation section (90) inside the stator (20). One end of the duct (80) may be positioned inside the stator (20) and the other end may protrude to the bottom of the stator (20).

[0067] In FIG. 3, the stator (20) is provided with an open bottom so that a duct (80) can protrude through the open bottom of the stator (20). Since the open bottom of the stator (20) is positioned to come into contact with the support member (10) and the interior is sealed, it may be difficult for a fluid containing air to circulate inside the stator (20).

[0068] One end of the duct (80) is positioned inside the stator (20) and the other end is directly connected to the outside through the open bottom of the stator (20), or the other end can be connected to a ventilation unit (90) positioned at the bottom of the stator (20).

[0069] The duct (80) extends from one end to the other, and the other end may be connected to a ventilation section (90) positioned at the bottom of the stator (20) and the top of the support section (10). The duct (80) extends inside the stator (20) to enable fluid movement in the height direction of the stator (20).

[0070] One end of the duct (80) is formed adjacent to the drive unit (60) so that outside air can be directed to the drive unit (60) which generates heat through operation, or heat generated from the drive unit (60) can be discharged to the outside.

[0071] The driving unit (60) may be positioned at a different height inside the stator (20), and one end of the duct (80) may be branched to correspond to the driving unit (60), so that the duct (80) may extend from the ventilation unit (90) and branch into a plurality of directions or heights.

[0072] The inside of the duct (80) may include a fan (83) that controls the flow of fluid.

[0073] The fan (83) can be placed inside the duct (80) or ventilation section (90) and can operate to cause fluid flow inside the stator (20).

[0074] In FIG. 3, the fan (83) is shown as a single fan (83) placed inside the duct (80), but is not limited thereto and multiple fans (83) may be placed in the duct (80) and the ventilation unit (90). Multiple fans (83) may operate depending on whether the drive unit (60) is driven or the driving time to circulate the internal fluid of the stator (20).

[0075] Even if multiple fans (83) are placed in the duct (80), the direction of fluid flow may vary depending on the shape of the blades of individual fans (83). Since intake or exhaust can be determined based on the shape of the blades relative to the rotation axis of the fans (83), multiple fans (83) placed in the duct (80) can independently perform the role of intake or exhaust.

[0076] For example, even if two fans (83) are placed inside the duct (80), one fan (83) can act as an exhaust fan that flows fluid toward the ventilation unit (90), and the other fan (83) can act as an intake fan that flows fluid toward the driving unit (60).

[0077] The operation of the fan (83) can be controlled by a control unit (not shown), and the operating state of the fan (83) can vary depending on the internal environment of the stator (20).

[0078] The control unit can receive information from the detection sensor (85) and control the operation of the pack.

[0079] The detection sensor (85) can detect the internal temperature and humidity of the stator (20) and can transmit the detected information to the control unit.

[0080] The sensing sensors (85) can be arranged in multiple numbers according to the height direction inside the stator (20) and are positioned adjacent to the driving unit (60) so that the operation of the fan (83) can be controlled by the heat generated from the driving unit (60).

[0081] The control unit can control the operation of the fan (83) by comparing the internal temperature or humidity detected through the detection sensor (85) with a preset value. The control unit can control the operation of the fan (83) according to the internal environment of the stator (20).

[0082] The control unit can control the operation of the fan (83) to discharge the internal fluid of the stator (20) to the outside of the stator (20) by operating the fan (83) or increasing the operating intensity of the fan (83) when the internal temperature or humidity of the stator (20) detected by the detection sensor (85) is higher than a preset value.

[0083] The control unit can stop the operation of the fan (83) or lower the operating intensity of the fan (83) when the internal temperature or humidity of the stator (20) becomes lower than a preset value.

[0084] A fan (83) may be placed in a duct (80) and a ventilation section (90), and the fan (83) placed in the duct (80) and the ventilation section (90) may have different fluid flow directions.

[0085] For example, a fan (83) placed in the duct (80) can flow outside air supplied through the ventilation unit (90) to one end of the duct (80), and a fan (83) placed on the side of the ventilation unit (90) can flow internal fluid of the stator (20) into the ventilation unit (90).

[0086] As explained in comparison with Fig. 3, the outside air rises along the duct (80) through the ventilation unit (90) and is supplied to the driving unit (60), and the internal fluid of the stator (20) descends from the driving unit (60) toward the ventilation unit (90) and can be discharged to the outside through the ventilation unit (90).

[0087] The internal fluid of the stator (20) can flow in a clockwise direction, and may also flow in a counterclockwise direction depending on the shape of the fan (83).

[0088] A ventilation opening (not shown) is formed between one end and the other end of the duct (80), and the ventilation opening may be opened toward the drive unit (60). The duct (80) may include a ventilation opening which is an open area between one end and the other end, and multiple ventilation openings may be arranged.

[0089] A plurality of ventilation openings may be arranged to correspond to the drive unit (60) and arranged along the height direction of the stator (20). At least one of the plurality of fans (83) may be arranged adjacently in the ventilation openings.

[0090] A fan (83) for controlling the flow of fluid through the ventilation port may be provided, and the operation, operating intensity, or rotation direction of the fan (83) may be controlled by a control unit. The fan (83) may discharge the internal fluid of the stator (20) to the outside of the stator (20) or circulate it inside the stator (20) through the ventilation port.

[0091] The ventilation unit (90) may be placed on the support unit (10) and connected to the other end of the duct (80). The ventilation unit (90) may share one surface with the outer surface of the support unit (10) and may be connected to the other end of the duct (80) on the upper surface.

[0092] The ventilation unit (90) can be fluidly connected to the outside through one side to receive outside air or discharge internal fluid of the stator (20). The ventilation unit (90) is connected to the support unit (10) and can be formed at the bottom of the stator (20) to easily ventilate the interior of the stator (20), where ventilation is difficult.

[0093] The ventilation unit (90) is positioned on the support unit (10) and shares one surface with the outer surface of the support unit (10), so that it can be coupled with a fluid containing external air through said one surface.

[0094] A fan (83) for controlling the flow of internal fluid of the ventilation unit (90) may be disposed on one side including the side or top surface of the ventilation unit (90).

[0096] FIG. 4 is a perspective view of a support member (10) in which a ventilation member (90) is arranged in a wind propulsion system (1) according to one embodiment of the present invention, and FIG. 5 is an enlarged view of a support member (10) in which a ventilation member (90) is arranged in a wind propulsion system (1) according to one embodiment of the present invention.

[0097] FIG. 4 illustrates a ventilation unit (90) positioned on a support member (10), wherein one surface of the ventilation unit (90) may be shared with the outer surface of the support member (10). A circular shape formed on the upper surface of the ventilation unit (90) is a part to which a duct (80) is connected, and the upper surface of the ventilation unit (90) and the other end of the duct (80) may be connected.

[0098] FIG. 5 is a cross-sectional view for explaining a ventilation unit (90) disposed on a support member (10), wherein a ventilation opening (95) may be formed on one side of the ventilation unit (90) that is shared with the outer surface of the support member (10). The ventilation opening (95) may be in the form of a door that can be opened and closed or may include the form of a fan (83).

[0099] The ventilation opening (95) is controlled by a control unit, so that if it is in the form of a door, the opening and closing can be controlled, and if it is in the form of a fan (83), the operation and intensity of the fan (83) can be controlled.

[0100] External air contained in the external fluid of the stator (20) can be introduced into the interior of the ventilation unit (90) through the ventilation port (95) of the ventilation unit (90), and the introduced external air can flow into the interior of the stator (20) through the duct (80) connected to the upper surface of the ventilation unit (90).

[0101] The internal fluid of the stator (20) can be introduced into the interior of the ventilation unit (90) through a fan (83) formed on one side of the duct (80) or the ventilation unit (90), and discharged to the outside through a ventilation port (95). The ventilation port (95) can serve as a passage connecting the interior of the ventilation unit (90) and the exterior of the ventilation unit (90).

[0102] The ventilation opening (95) may include a plurality of doors or a plurality of fans (83), and may also include a combination of doors and fans (83). As previously described, depending on the shape of the fan blades (83), the fan (83) may perform the role of intake or exhaust, and the ventilation opening (95) may include fans (83) that perform the roles of intake and exhaust.

[0103] Intake or exhaust may occur in the ventilation port (95) by control of the control unit, and the flow of the external air and the internal fluid of the ventilation unit (90) may change.

[0105] FIG. 6 is a perspective view of a support member (10) in which a ventilation member (90) is arranged in a wind propulsion system (1) according to another embodiment of the present invention.

[0106] The shape of the support member (10) in FIG. 6 may differ from that in FIG. 4. The support member (10) may include a leg-shaped support member (13), and an opening (15), which is an open area, may be formed between the support members (13).

[0107] The support member (10) is formed such that at least a portion is open through the opening (15), allowing fluid flow to occur through the opening (15). A ventilation member (90) is disposed on the upper surface of the support member (10), and the ventilation member (90) may share one surface with the outer surface of the support member (10). The ventilation member (90) may be formed adjacent to the outer surface of the support member (10).

[0108] The support member (10) is formed so that its outer surface contacts the stator (20), and the stator (20) may have an open bottom so that the open bottom of the stator (20) and the upper surface of the support member (10) can be positioned to face each other. The support member (10) may have a portion of its upper surface open, excluding the portion where the ventilation member (90) is positioned.

[0109] Although shown in the shape of a rectangle in Fig. 6, the shape of the open portion may vary. The inside and outside of the stator (20) can be fluidly connected through the open portion on the upper surface of the support member (10).

[0110] The interior of the stator (20) is connected to the outside through the ventilation section (90), but it can also be connected to the outside through a portion of the area open on the upper surface of the support section (10). Since the support section (10) includes an opening (15) which is an area open between the support members (13), the interior of the stator (20) can be fluidly connected to the opening (15) through a portion of the area open on the upper surface of the support section (10).

[0111] Even if the duct (80) and ventilation unit (90) are not operating, the interior of the stator (20) can be fluidly connected to the outside through a partial area and an opening (15) that are open on the upper surface of the support member (10). The partial area open on the upper surface of the support member (10) can be formed to be openable and closable in the form of a door, similar to a ventilation opening (95).

[0113] FIG. 7 is a perspective view of a wind propulsion system (1) according to another embodiment of the present invention.

[0114] Generally, the support member (10) is formed on the deck (S) and can be formed in the shape of a column with a continuous outer surface. The support member (10) is formed in a closed structure or a sealed form and is not fluidly connected to the stator (20) and rotor (30), and can simply serve to support the stator (20) and rotor (30).

[0115] In FIG. 7, the support member (10) may be formed such that a portion of the outer surface is open, rather than being in the form of a continuous column. The support member (10) may support the stator (20) and the rotor (30) through a leg shape excluding the portion open on the outer surface.

[0116] The rotor (30) is rotatably connected to the stator (20) and is formed with an open upper and lower end, with an end plate (40) installed on the upper end and the stator (20) inserted through the open lower end.

[0117] The specific configuration of the support member (10) is examined in FIGS. 8 to 10.

[0119] FIG. 8 is a cross-sectional view of a wind propulsion system (1) according to another embodiment of the present invention, and FIG. 9 is a perspective view of a cross-section of a wind propulsion system (1) according to another embodiment of the present invention.

[0120] A wind propulsion system (1) may include a support member (10) positioned on a deck (S), a stator (20) vertically connected to the support member (10), and a rotor (30) formed to surround the outside of the stator (20) and rotatably connected to the stator (20).

[0121] Specifically, it includes a disk (50) in contact with the inner surface of the rotor (30), and the disk (50) is connected to the stator (20) and can rotate together with the rotor (30) relative to the stator (20). The disk (50) can receive power through a driving part (60) formed inside the stator (20) or protruding from the stator (20).

[0122] The drive unit (60) can transmit power to cause the rotor (30) to rotate, and the disk (50) rotates by the power of the drive unit (60), and the rotor (30) connected to the disk (50) rotates together to help propel the ship (100).

[0123] The support member (10) may include a leg-shaped support member (13), a plate-shaped support plate (11), and an opening (15) which is an open area.

[0124] The support members (13) can be formed vertically with respect to the deck (S) and can be formed and arranged in multiple numbers. The support members (13) can be arranged along the circumference of the stator (20) or rotor (30), so that the spacing and angle between the support members (13) may vary depending on the number of support members (13).

[0125] The cross-section of the support member (13) may vary depending on the height, and the cross-section may become narrower or smaller in the height direction away from the deck (S). The cross-section of the support member (13) with respect to the surface parallel to the support plate (11) may be formed wider as it gets closer to the deck (S).

[0126] Referring to FIG. 8, the support member (13) may have a cross-section that narrows or becomes smaller as it approaches the support plate (11), so that the outer surface of the support member (13) may be formed to be inclined. The support plate (11) may have a shape that is inclined toward the stator (20) or rotor (30) from the deck (S).

[0127] The arrangement of the support members (13) may vary depending on the number formed, and if the support members (13) are provided in a multiple of 2 or an even number, they may be arranged to face each other.

[0128] The support plate (11) is supported by the support member (13) and can come into contact with the stator (20) on the upper surface. The support plate (11) can be positioned at a height lower than the height of the support member (13) and can be surrounded by the support member (13).

[0129] Referring to FIG. 9, the support plate (11) may have some areas open, and the open areas may be placed inside the stator (20). Through the open areas of the support plate (11), the inside of the stator (20) may be fluidly connected to the outside.

[0130] The interior of the stator (20) allows for free inflow and outflow of outside air through an open portion of the support plate (11), so the temperature rise and humidity rise caused by the operation of the drive unit (60) can be resolved through air circulation.

[0131] The opening (15) is an area open between the supports (13), and the outer surface or side of the support member (10) can be formed by the supports (13) and the opening (15). Referring to FIG. 8, the opening (15) can be formed at the top by the support plate (11), at both sides by the supports (13), and at the bottom by the deck (S).

[0132] The opening (15) corresponds to the portion of the outer surface of the support member (10) excluding the support member (13), and may coincide with the open area between the support members (13). The opening (15) allows for the inflow and outflow of fluid, so that fluid introduced through one opening (15) can be discharged through another opening (15) at the bottom of the support plate (11).

[0133] At least two or more openings (15) can form a fluid path, so that a fluid path can be formed inside the support member (10) or below the support plate (11).

[0134] The fluid introduced through the flow path flows into the interior of the stator (20) through an open portion of the support plate (11), allowing the flow path to facilitate the circulation of the internal fluid of the stator (20).

[0135] The internal fluid of the stator (20) can be discharged through an open portion of the support plate (11) by the flow of fluid moving along the path, so that the path allows the internal fluid of the stator (20) to circulate easily.

[0136] Although the Euro may be difficult to verify visually as a conceptual passage, a Euro can be formed by connecting at least two of the multiple openings (15).

[0137] One of the multiple openings (15) may be formed in the shape of a curve corresponding to the outer circumference of the support plate (11) formed between the support members (13). One opening (15) may correspond to a portion of a virtual cylinder with the outer circumference of the support plate (11) as its diameter.

[0138] The opening (15) is formed between the supports (13), and the portion of the outer circumference of the support plate (11) excluding the portion in contact with the support (13) may correspond to the upper portion of the opening (15). The sum of the upper portions of the multiple openings (15) may be formed to be 50% or more of the outer circumference of the support plate (11).

[0139] Multiple openings (15) can be formed at the outer circumference of the support plate (11) such that they are equal to or larger than the circumference in contact with the support member (13), so that the cross-section of the flow path formed by the openings (15) can be widened.

[0141] FIG. 10 is a plan view of a support member (10) in a wind propulsion system (1) according to another embodiment of the present invention. In FIG. 10, the support member (10) may include four supports (13) and four openings (15).

[0142] Four support members (13) are connected on the side of the support plate (11), and an opening (15) is formed between each of the four support members (13), so that there may be four openings (15). The support member (10) includes a plurality of support members (13) and a plurality of openings (15), and at least one pair of the openings (15) among the plurality of openings (15) may be formed to face each other.

[0143] At least one pair of openings (15) can form a fluid passage. Among the plurality of openings (15), the remaining openings (15) can be formed facing in a direction perpendicular to the passage formed by at least one pair.

[0144] The flow path formed by the remaining opening (15) among the multiple openings (15) can be formed perpendicular to the flow path formed by at least one pair. The flow path is conceptual, and a single flow path can be formed through two openings (15), but the flow path does not need to be formed in a straight line. The flow path can be formed between adjacent openings (15) and can be formed in a curved shape, but for convenience of explanation, it has been described as a straight flow path.

[0145] In FIG. 10, the support member (10) may have at least one pair of openings (15) formed facing each other and at least one pair of supports (13) formed facing each other. The opening (15) formed between the supports (13) may be defined as an open area between the support plate (11) and the deck (S).

[0146] The opening (15) may be formed as a curve such that its upper portion corresponds to the space between the supports (13) on the outer circumference of the support plate (11). In the case of multiple openings (15), the sum of the upper portions may be formed to be at least 50% of the outer circumference of the support plate (11). The opening (15) may have a cross-section wider than the supports (13) with respect to a surface parallel to the height direction.

[0147] The support member (10) includes at least one flow path, and air circulation can be facilitated compared to a column-shaped support member (10) with a continuous outer surface. Air circulation can be facilitated if the openings (15) are formed facing each other and include a straight flow path.

[0148] The Euro can be fluidly connected to the interior of the stator (20) through an open portion of the support plate (11), thereby allowing the internal fluid of the stator (20) to be circulated without the need for additional equipment.

[0149] Some of the open areas in the support plate (11) can be formed in multiple parts, and one area can be designated as an intake area and another area as an exhaust area.

[0150] Some areas open in the support plate (11) may allow for simultaneous intake and exhaust, and for this purpose, ventilation equipment such as a fan (83) may be provided.

[0151] The user can enter and exit through the opening (15), allowing easy access when maintenance is required on the support member (10) or the stator (20). It is also easy to enter the interior of the stator (20) through an open portion of the support plate (11).

[0152] The present invention may include a vessel (100) including the above wind propulsion system (1).

[0153] The present invention is not limited to the embodiments described above, and may include a combination of the above embodiments or a combination of at least one of the above embodiments and known technology as another embodiment.

[0154] Although the present invention has been described in detail through specific embodiments, this is for the purpose of specifically explaining the invention, and the invention is not limited thereto. It will be apparent that modifications or improvements can be made by those skilled in the art within the technical scope of the invention.

[0155] All simple variations or modifications of the present invention fall within the scope of the present invention, and the specific scope of protection of the present invention will be clarified by the appended claims. Explanation of the symbols
