Description

[Technical field]

[0001] The present invention relates to a modified variable spiral cylinder that is a modified version of a variable spiral, and to a propeller and nozzle that use the same. [Background technology]

[0002] A conventional technique for constructing a propeller-like propeller using a spiral is the Registered Utility Model No. 20-0278161 "Spiral Blade Propeller for Ships" registered and published on June 20, 2020. The propulsion section of the propulsion device shown in FIG. 1 has a spiral blade 44 welded in the longitudinal direction on a rotating shaft 43 that penetrates the interior of a fixed hollow cylindrical casing 42, a driven shaft 22 is connected to the rotating shaft 43, and both ends of the rotating shaft 43 are rotatably supported by a rotation support means 70. The spiral blade 44 rotates to cause seawater to flow into the inlet conduit 32, and at the same time, pressurizes the tapered conduit 51.

[0003] Another prior art technique for constructing a propeller or other thruster using a spiral is the application of a spiral blade or fin formed on the outer periphery of a cylindrical cylinder extending in one direction to an amphibious vehicle, as disclosed in Patent No. 10-1703873 "Spiral Upper Half-Driven Cylindrical Propulsion Body" published on February 7, 2017. The cylindrical propulsion body shown in Fig. 2 is a type in which a spiral propulsion protrusion 121 is provided on the outer surface of a cylindrical propulsion member 120 formed long in the front-rear direction to generate thrust.

[0004] However, all of the above-mentioned prior arts are cylindrical, i.e., cylinders in which a helical blade is attached to the outside, and the cylinder itself is not formed in a helical shape. As far as the inventor of the present invention knows, there has been no prior art proposal for forming a cylinder in a helical shape inside the main body of a certain propellant to obtain a propulsive force. Summary of the Invention [Problem to be solved by the invention]

[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a cylinder having an empty space formed inside the body.

[0006] SUMMARY OF THE PRESENT EMBODIMENT The present invention aims to provide a propeller and nozzle having a modified variable spiral cylinder formed within the body.

[0007] The present invention aims to provide a cylinder that can adjust the internal flow of a fluid by adjusting the ratio of the body section to the outlet section, the rotation speed and the number of internal cylinders, the number of external pins and internal cylinders, etc., and a propeller and nozzle using the same.

[0008] The present invention aims to provide a means of transportation such as a ship, submarine, aircraft, drone, etc. to which the above-mentioned cylinder, propeller, nozzle, etc. are applied. [Means for solving the problem]

[0009] The modified variable spiral cylinder of the present invention is basically based on a spiral in space. A spiral starts from a point in space, rotates around a central axis, traces a trajectory, and has a shape similar to that of a commonly seen spring. The elements that define a spiral are the radius, pitch, and height of the spiral. A variable spiral is a spiral in which the radius and period are modified, and in the present invention, it is characterized by a shape in which the radius of the lower end becomes smaller as it goes up. The modified variable spiral (mVHC) is another modification of the variable spiral, and its most notable feature is that the outlet section of the variable spiral is modified to be almost parallel to the central axis of rotation.

[0010] A spiral cylinder according to one embodiment of the present invention is a spiral cylinder having a hollow cylindrical shape with a predetermined radius based on a cylinder center line that rotates in a spiral shape around a central axis of rotation, the cylindrical shape has a form that rotates in a spiral shape along the cylinder center line, the cylindrical shape has an inlet for the inflow of a fluid and an outlet for the outflow of the fluid, and the outlet portion of the cylindrical shape extends parallel to the central axis of rotation.

[0011] The diameter of the inlet is larger than the diameter of the outlet, and the diameter of the cylindrical shape gradually decreases from the inlet side to the outlet side.

[0012] The present invention is also characterized in that the distance between the cylinder center line and the central axis of rotation gradually decreases from the inlet side to the outlet side of the cylindrical shape.

[0013] A spiral cylinder according to another embodiment of the present invention is a spiral cylinder comprising a plurality of basic cylinders which rotate in a spiral fashion around the same central axis of rotation, the basic cylinders each having an inlet for the inflow of a fluid and an outlet for the outflow of the fluid, the cylinder body between the inlet and the outlet being sealed, the number of spiral rotations with respect to the total length of the spiral cylinder being M (where M is a positive real number), and the number of the basic cylinders being N (where N is a natural number).

[0014] The N basic cylinders are also characterized in that they are spaced apart from each other and in the same phase.

[0015] The basic mold cylinder is also characterized in that its diameter gradually decreases from the inlet side to the outlet side, and the outlet portion of the basic mold cylinder is provided with an outlet section in which the basic mold cylinder extends parallel to the central axis of rotation.

[0016] The cross section of the basic cylinder is preferably circular or polygonal.

[0017] A propeller according to one embodiment of the present invention is characterized in that it is configured to include the spiral cylinder and a casing that surrounds the spiral cylinder.

[0018] A propeller according to another embodiment of the present invention comprises a body having F pins and N cylinders formed within the body, where F and N are natural numbers, and the cylinders are embodied as empty spaces.

[0019] In addition, each cylinder is realized as an empty space having a predetermined radius based on a cylinder center line that rotates spirally with respect to the rotation center axis of the propeller.

[0020] Each cylinder has an inlet for the inflow of a fluid and an outlet for the outflow of the fluid, and the diameter of the cylinder gradually decreases from the inlet side to the outlet side.

[0021] The present invention is also characterized in that the distance between the cylinder center line and the rotation central axis gradually decreases from the inlet side to the outlet side.

[0022] The present invention is also characterized in that an outlet section is provided at the outlet portion of each of the cylinders, in which the cylinders extend in parallel to the central axis of rotation.

[0023] The N cylinders are also spaced apart from one another and in the same phase.

[0024] The (N, F) is one of (3, 3), (3, 6), and (5, 5).

[0025] Meanwhile, a nozzle according to one embodiment of the present invention is a nozzle comprising a cylinder section including a plurality of basic cylinders rotating in a spiral around the same central axis of rotation, and a cylindrical section connected to the cylinder section, wherein the basic cylinder has an inlet for the inflow of a fluid from the cylindrical section and an outlet for the outflow of the fluid, the cylinder body between the inlet and the outlet is sealed, and the plurality of basic cylinders are spaced apart from each other in the same phase.

[0026] The basic cylinder is characterized in that its diameter gradually decreases from the inlet side to the outlet side.

[0027] The present invention is also characterized in that an outlet section extending parallel to the central axis of rotation is provided at the outlet portion of the basic mold cylinder.

[0028] The basic cylinder is characterized in that the distance between the cylinder center line and the rotation center axis gradually decreases from the inlet side to the outlet side. Effect of the Invention

[0029] According to the present invention, a cylinder is provided having an empty space formed inside a body.

[0030] The present invention also provides a propeller and nozzle having a modified variable spiral cylinder formed within a body.

[0031] Furthermore, according to the present invention, it is possible to provide transportation means such as ships, submarines, aircraft, drones, etc., to which the cylinders, propellers, nozzles, etc. are applied.

[0032] On the other hand, by adjusting the ratio of the outlet section of the modified variable spiral cylinder of the present invention, adjusting one or more of the correlation between the rotation speed of the fins and the cylinder, or the correlation between the number of fins and the cylinder, it becomes possible to control the flow of the fluid inside the cylinder and the thrust at the outlet.

[0033] The major difference between the modified variable spiral cylinder (mVHC) of the present invention and the existing conventional cylindrical cylinder is the cohesive force of the water and air flows. The process is as follows. First, the water or air flows that flow in through the inlet section of the modified variable spiral cylinder due to external rotational motion or external pressure enter the trunk section at a high speed and increasing pressure according to the shape of the cylinder that is sealed and becomes increasingly narrow. Second, the water and air flows that enter the trunk section while maintaining a high speed and high pressure generate an internal rotational force in the trunk section. The internal rotational force and pressure continue to be maintained due to the water and air flows that continuously flow into the inlet section. Third, the internal rotational force and pressure increase due to the shape of the cylinder that becomes increasingly narrower in diameter, and they are completely cohesive in the outlet section without any lost water or air flows, and switch to linear thrust and injection force parallel to the central axis.

[0034] In other words, when water and air flows into the modified variable spiral cylinder of the present invention, the flow naturally switches to linear motion through a spiral rotational motion, thereby enabling the flowing water and air flows to be converted into thrust or jet force completely parallel to the central axis.

[0035] Modified variable spiral (mVHC) propellers and nozzles are based on the same principle as cylinders, but in the case of a propeller, water pressure or air pressure is generated in the cylinder by external rotational force, while in the case of a nozzle, water pressure or air pressure acts from the outside. In the case of a nozzle, the water pressure and air pressure that continuously flows into the nozzle inlet section maintains the nozzle's internal rotational force, and this pressure increases due to the increasingly narrow cylinder shape, and without resistance and without lost water or air flow, it is completely concentrated in the outlet section and switches to linear thrust and injection force parallel to the central axis.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0037] The deformed variable spiral cylinder is basically based on a spiral in space. The spiral starts from a point in space, rotates around one central axis (hereafter referred to as the central axis of rotation), traces a trajectory, and is similar in shape to a commonly seen spring. The elements that define a spiral are the radius, pitch, and height of the spiral. Generally, when a spiral is projected onto a two-dimensional xy plane, its shape is a circle, and when a spiral is projected onto an xz or yz plane, its shape is a sine curve. The pitch can be simply said to be the period of this sine curve. The height is the total height of the spiral in space.

[0038] On the other hand, a variable spiral is one in which the radius and period of the spiral are modified. A variable spiral has a shape in which the radius of the bottom end becomes smaller as it goes up. In other words, when a variable spiral is projected from above onto a two-dimensional plane (xy plane), its shape becomes a spiral. The modified variable spiral (mVHC) of the present invention is another modification of the variable spiral. Its greatest feature is that the variable spiral outlet section is modified to be almost parallel to the central axis.

[0039] A cylinder using such a deformable variable spiral can naturally convert the water and air flows that flow into a rotational motion into a linear motion through the rotational motion. Furthermore, if the angle and shape are set so that the maximum water and air flows flow into the cylinder at the inlet section, this leads to an increase in internal pressure, resulting in an effect of switching to a stronger linear motion. In addition, the deformable variable spiral cylinder can convert the water and air flows into a thrust or jet force that is completely parallel to the central axis without any water or air flows being lost when the water and air flows switch from a rotational motion to a linear motion, when closed except for the inlet and outlet.

[0040] The following will explain in detail with reference to the accompanying drawings everything from the principle of the spiral to application examples to which the modified variable spiral cylinder is applied.

[0041] FIG. 3 shows a helix and is made up of detailed views of FIGS. 3A-3L projected in different directions.

[0042] A spiral is a continuous curve in three-dimensional space rotating around a given axis. A spiral is commonly described using the following parametric equation: x(t)=a cos(t) y(t)=a·sin(t) z(t)=b t

[0043] 3A, a spiral 1000 rotates around a central axis of rotation 1001, proceeding from a starting point 1002 to an end point 1003 at a fixed interval, i.e., radius 1004. The spiral radius 1004 corresponds to a in the parametric equation, and the spiral pitch (=2π·b) means the distance between peaks and valleys on the vertical axis (z-axis), and corresponds to the distance from one point on the spiral to another point located on the same z-axis, based on the z-axis, which is the vertical axis.

[0044] The spiral 1000 of FIG. 3A rotates a total of one revolution around the central axis of rotation 1001 and has a constant radius (a) and a constant pitch (2π·b). For a one revolution spiral, the height and pitch of the spiral are the same. The spiral 1007 of FIG. 3B is a plan view of the spiral 1000 of FIG. 3A having a radius (a) 1008, and it can be seen that the shape of the spiral 1000 seen from above is a circle. The spiral 1010 of FIG. 3C corresponds to a side view of the spiral 1000 of FIG. 3A rotated 90 degrees, and its form shows the central axis of rotation 1011 (1001 in FIG. 3A), radius 1012 (1004 in FIG. 3A), and pitch 1013 (1005 in FIG. 3A) as a sine curve.

[0045] Each spiral 1020, 1027, 1030 in Figures 3D, 3E, and 3F rotates twice around a central axis of rotation 1021 from a starting point 1022 to an end point 1023. As in the spiral sets in Figures 3A, 3B, and 3C, in the spiral sets in Figures 3D, 3E, and 3F, Figure 3E is a plan view of the spiral in Figure 3D, and Figure 3F corresponds to a 90-degree rotated side view of the spiral in Figure 3D. This directional relationship between the spirals in each spiral set in Figure 3 is similarly applied to the other spiral sets described below.

[0046] 4A, 4B, 4C and 4D, which are detailed views of FIG. 4, show spiral cylinders which correspond to the spirals of FIGS. 3A, 3D, 3G and 3J, respectively.

[0047] In FIG. 4A, the spiral cylinder 1100 rotates once from one end 1105 to the other end 1102 around the central axis of rotation 1101, and has a hollow cylindrical spiral structure having a radius 1104 (hereinafter, the cylinder radius) based on the cylinder center line 1103.

[0048] 4B is a spiral cylinder 1120 that rotates twice around a central axis of rotation 1121 from one end 1125 to the other end 1122, and has a hollow cylindrical spiral structure having a cylinder radius 1124 based on a cylinder center line 1123.

[0049] Spiral cylinder 1140 in FIG. 4C rotates three times from one end 1145 to the other end 1142 around central axis of rotation 1141, and has a hollow cylindrical spiral structure having cylinder radius 1144 based on center line 1143.

[0050] Spiral cylinder 1160 in FIG. 4D rotates four times from one end 1165 to the other end 1162 around central axis of rotation 1161, and has a hollow cylindrical spiral structure having cylinder radius 1164 based on center line 1163.

[0051] In this way we can generalize the spiral cylinder with n rotations.

[0052] FIG. 5 shows the variable helix and is composed of detailed views of FIG. 5A to FIG. 5L projected in different directions. The positional relationship of each detailed view of FIG. 5 is the same as that of FIG. 3.

[0053] A variable spiral rotates around a central axis as a continuous curve in three-dimensional space, but is characterized by a gradually increasing or decreasing radius and pitch as it rotates. Variable spirals are generally described using the following parametric equations: x(t)=a f(t) cos(t) y(t)=a f(t) sin(t) z(t)=b f(t)

[0054] 5A, variable spiral 2000 rotates around rotation axis 2001, progressing from start point 2001 to end point 2003, with the radius becoming smaller and the pitch becoming larger the further up. Spiral radius 1004 corresponds to a·f(t), and the spiral pitch corresponds to 2π·b·f(t).

[0055] The spiral sets 2000, 2005, 2008 of Figures 5A, 5B and 5C rotate a total of one time (n=1) around the central axis of rotation 1001, and therefore have the same spiral height h and pitch p. The spiral 2005 of Figure 5B has a larger radius 2006 at the start point 2002 than the radius 2007 at the end point 2003. Figure 5B is a top view of Figure 5A, and it can be seen that the shape of the spiral 2000 seen from above is the spiral 2005 locus. The spiral 2008 of Figure 5C corresponds to a side view of the spiral 2000 of Figure 5A rotated 90 degrees, and shows a central axis 2009, decreasing radii 2010, 2011, and a pitch 2012 equal to the height.

[0056] Each spiral 2020, 2025, 2028 in Figures 5D, 5E, and 5F rotates twice around a central axis of rotation 2021, 2029 from a starting point 2022 to an end point 2023. The total height 2024(h) is equal to the sum of the magnitude of a first pitch 2032 including the starting point and a second pitch 2033 including the end point. As one moves from the starting point 2022 to the end point 2023, the magnitude of the radius decreases from a start radius 2026, 2030 to an end radius 2027, 2031, and the magnitude of the pitch increases from a first pitch 2032 to a second pitch 2033.

[0057] Each spiral 2040, 2045, 2048 of the spiral sets of Figures 5G, 5H and 5I is a three turn configuration with a total height 2044(h) equal to the sum of the magnitudes of the first pitch 2052, the second pitch 2053 and the third pitch 2054. The radius and pitch magnitudes are variable as in Figures 5D, 5E and 5F.

[0058] Each spiral 2060, 2065, 2068 of the spiral sets of Figures 5J, 5K and 5L has a four turn configuration, the total height 2064 is equal to the sum of the magnitudes of the first through fourth pitches 2072-2075, and the radius and pitch are variable in the same manner as in Figures 5D, 5E and 5F.

[0059] The variable spiral applied in the present invention is a variable spiral with n turns, the total height h of which is equal to the sum of the pitches p1...pn contained in the spiral, and can be generalized as a variable spiral with n turns in the form of a decreasing radius and an increasing pitch along the direction of travel.

[0060] In the above variable spiral, the case where the radius and pitch increase along the direction of the spiral has been described, but the variable spiral can also include cases where both the radius and pitch decrease, where one of the radius and pitch is fixed as a constant and only the other increases or decreases, or where one of the radius and pitch increases and the other decreases. Such concepts are obvious to those skilled in the art, so detailed explanations will be omitted.

[0061] 6A, 6B, 6C and 6D, which are detailed views of FIG. 6, show variable spiral cylinders corresponding to the spirals of FIGS. 5A, 5D, 5G and 5J, respectively.

[0062] In FIG. 6A, variable spiral cylinder 2100 rotates once around rotation center axis 2101 from one end 2105 to the other end 2102, and has a hollow cylindrical spiral structure having a constant radius 2104 based on cylinder centerline 2103.

[0063] The variable spiral cylinder 2120 in FIG. 6B rotates twice around a central axis of rotation 2121 from one end 2125 to the other end 2122, and has a hollow cylindrical spiral structure having a constant radius 2124 based on a cylinder center line 2123.

[0064] Variable spiral cylinder 2140 in FIG. 6C rotates three times from one end 2145 to the other end 2142 around central axis of rotation 2141, and has a hollow cylindrical spiral structure having a constant radius 2144 based on cylinder centerline 2143.

[0065] Variable spiral cylinder 2160 in FIG. 6D rotates four times from one end 2165 to the other end 2162 around central axis of rotation 2161, and has a hollow cylindrical spiral structure having a constant radius 2164 based on cylinder centerline 2163.

[0066] In this way we can generalize the spiral cylinder with n rotations.

[0067] Figure 7 shows a deformable and variable spiral according to the present invention. The spiral set in Figures 7A to 7F, which are detailed views, shows an example of a one-turn deformable and variable spiral.

[0068] The modified variable spiral proposed in this invention is characterized in that the starting radius is larger than the end radius, and the end points of the spiral do not show a rotation trajectory relative to the central axis of rotation, but converge to a straight line approximately parallel to the central axis. The formula used here is: x(t) = a exp(ct) cos(t) y(t)=a exp(ct) sin(t) z(t) = b exp(dt) Based on this, additional deformations were applied to ensure linear convergence near the endpoints.

[0069] Based on the front view of FIG. 7C, the plan view of FIG. 7A, the right side view of FIG. 7D, and the bottom view of FIG. 7E are arranged on the upper, right, and lower sides, respectively, and the isometric view of FIG. 7B and the isometric view of FIG. 7F are arranged on the upper right and lower right sides, respectively.

[0070] 30. Referring to said figures, modified variable spirals 3000, 3003, 3006, 3009, 3012, 3015 run from the start of the spiral portion towards the end points of quasi-linear portions 3005, 3008, 3011, 3014, 3017 based on the central axis of rotation 3004, 3007, 3010, 3013, 3016, with a starting radius 3001 greater than an end radius 3002, and the ends of the spirals being parallel to the central axis of rotation and forming an approximately straight line.

[0071] Each detail of FIG. 8 shows a modified variable spiral cylinder (mVHC) according to the present invention.

[0072] A deformed variable spiral cylinder is a cylinder to which the geometry of the deformed variable spiral of the present invention is applied. If there is one cylinder around the central axis of rotation, it is called a 1-phase cylinder, if there are two, it is called a 2-phase cylinder, if there are three, it is called a 3-phase cylinder, if there are N cylinders, it is called an N-phase cylinder, etc.

[0073] FIG. 8 shows a one-rotation one-phase variable spiral cylinder, with the top, right, bottom, and bottom sides being the top view of FIG. 8A, the right side view of FIG. 8D, the bottom view of FIG. 8E, and the back view of FIG. 8G, respectively, based on the front view of FIG. 8C, and the top right and bottom right sides being the isometric views of FIG. 8B and FIG. 8F, which are isometric views seen obliquely from the front. The isometric view of FIG. 8H is an isometric view seen obliquely from the back. For reference, the same reference numbers are used for the same components, and the same is true for the remaining figures below.

[0074] The modified variable spiral cylinder 3020 in Figure 8 is designed with an inlet radius, i.e., starting radius, larger than the outlet radius, i.e., end radius, where the pitch can be designed to be the same, increasing or decreasing along the spiral progression direction.

[0075] 8A to 8H are generated with a modified variable spiral 3022 as the cylinder center line, and the modified variable spiral 3022 and the modified variable spiral cylinder 3020 have a shape that rotates in a spiral shape about a rotation center axis 3021. The modified variable spiral cylinder is characterized in that it has a shape that narrows from the inlet 3023 side toward the outlet 3025, and that near the outlet the cylinder has a shape that advances in a direction parallel to the rotation center axis.

[0076] As clearly shown in the right side view of Figure 8D, the modified variable spiral cylinder can be distinguished into a body section 3036 and an outlet section 3037. The body section 3036 is the section where the cylinder rotates in a spiral along the spiral centerline, and the outlet section 3037 is the section where the cylinder straightens in a direction parallel to the central axis of rotation of the spiral near the exit of the spiral.

[0077] Next, the case where the deformable variable spiral cylinder is applied to a propellant will be described.

[0078] First, it is assumed that an external rotational force is applied to the central rotation axis 3021 of the one-rotation, one-phase deformable variable spiral cylinder in FIG. 8, causing the cylinder to rotate in a fixed direction.

[0079] In each of Figures 8A to 8H, the rotation direction of the deformable variable spiral cylinder is indicated by an arrow. With reference to the front view of Figure 8C, the deformable variable spiral cylinder 3020 rotates in a counterclockwise direction 3024 about the rotation center axis 3021, and rotates in a clockwise direction in the rear view of Figure 8G. As a result, in the plan view of Figure 8A, the inlet 3023 of the deformable variable spiral cylinder rotates in a direction penetrating the ground, and in the bottom view of Figure 8E, the inlet 3023 of the deformable variable spiral cylinder rotates in a direction penetrating and exiting the ground.

[0080] When the deformable variable spiral cylinder is placed in a fluid, the fluid, such as water or air, flows into the inlet 3023 due to the rotational motion of the deformable variable spiral cylinder, moves along the sealed cylinder, and then exits at the outlet 3025. When the fluid flows into the inlet of the deformable variable spiral cylinder due to an external rotational force, the inlet fluid passes through the body section of the deformable variable spiral cylinder, generating an internal rotational force. In addition, the inner diameter of the cylinder narrows as the fluid moves toward the outlet, generating pressure in the fluid, which causes the compressed fluid to be ejected at the outlet of the deformable variable spiral cylinder, generating thrust. Using this principle, the deformable variable spiral cylinder can be used as a propellant.

[0081] Next, a multi-phase (N-phase) deformation variable spiral cylinder in which two or more cylinders are combined will be described with reference to Figures 9 to 11. The mutual arrangement of the detailed views of Figures 9 to 11 is the same as that of Figure 8.

[0082] First, the one-rotation two-phase variable spiral cylinder 3100 shown in Fig. 9 is made by alternately arranging two one-rotation one-phase variable spiral cylinders. It has a structure in which two identically shaped variable spiral cylinders are arranged with a phase difference of 180 degrees via a central rotation axis 3101. The inlets 3102 and 3103 face in opposite directions, and the cylinder rotates in a counterclockwise direction 3104.

[0083] 9, each cylinder has an inner diameter that narrows from the inlet side toward the outlet side, and near the outlet, the cylinder advances in a direction parallel to the central axis of rotation, and each outlet 3131, 3132 faces the same direction. Overall, it can be divided into body sections 3141, 3142 and an outlet section 3143, and the body section can be further divided into an inlet section 3141 and a body section 3142.

[0084] In a one-rotation, two-phase cylinder, when fluid flows into the cylinder inlet due to an external rotational force, it passes through the cylinder's body section and is compressed by an internal rotational force, and is ejected from the outlet, generating thrust. When the same external rotational force as that of a one-rotation, one-phase cylinder is applied to a one-rotation, two-phase cylinder, the total thrust increases proportionately due to the two cylinders.

[0085] Next, a one-rotation, three-phase deformation variable spiral cylinder in which three one-rotation, one-phase deformation variable spiral cylinders are alternately arranged with a phase difference of 120 degrees will be described with reference to FIG.

[0086] In Figure 10, the inlets are arranged at an angle of 120 degrees, and the cylinder rotates counterclockwise. The inner diameter of each cylinder of the one-rotation three-phase variable spiral cylinder also narrows from the inlet side to the outlet side, and near the outlet, it progresses in a direction parallel to the central axis of the cylinder rotation, and can be divided into a body section and an outlet section.

[0087] The thrust generation process of the one-rotation three-phase cylinder is similar to that of the one-phase and two-phase cases, and when the same external rotational force is applied, the total thrust increases proportionally due to the three cylinders.

[0088] Next, Fig. 11 shows a one-rotation five-phase variable spiral cylinder in which five one-rotation one-phase variable spiral cylinders are alternately arranged with a phase difference of 72 degrees. The operation mechanism of the one-rotation five-phase variable spiral cylinder is the same as the other multi-phase variable spiral cylinders. However, the inner diameters of the inlets and outlets of the five individual cylinders applied to the one-rotation five-phase cylinder are smaller than those of the one-rotation one-phase cylinder.

[0089] Here, the multi-rotation deformable variable spiral cylinder will be described with reference to Figs.

[0090] For this reason, we will first describe the multi-turn variable spiral. Except for the fact that the multi-turn variable spiral is a spiral that rotates two or more times, it has the same characteristics as the single-turn variable spiral, such as the fact that the starting radius is larger than the ending radius and that the spiral converges to a straight line parallel to the central axis of rotation at the end point of the cylinder in order to eject the fluid parallel to the central axis of rotation.

[0091] Figure 12 shows an example of a two-turn variable spiral. The arrangement of the details is the same as that of the one-turn variable spiral in Figure 7.

[0092] In the case of the two-rotation deformed variable spiral 3400, the equation expressing the geometric shape is the same as that of the one-rotation deformed variable spiral, and the deformation is also the same, in that the starting radius 3401 is larger than the end radius 3402 and converges parallel to the rotation central axis near the end point 3405.

[0093] The cylinder diagram in Figure 13 shows an example of a two-rotation one-phase variable spiral cylinder to which a two-rotation variable spiral is applied. The illustrated two-rotation one-phase variable spiral cylinder has a shape in which the spiral radius and the cylinder inner diameter decrease from the inlet to the outlet in order to increase compression from the inflowing fluid. Here, the positional relationship of each diagram is the same as that of the one-rotation one-phase variable spiral cylinder.

[0094] The two-rotation, two-phase deformable variable spiral cylinder in Fig. 14 is formed by arranging two of the two-rotation, one-phase deformable variable spiral cylinders in Fig. 13 with a phase difference of 180 degrees. When the same external rotational force as that of the two-rotation, one-phase cylinder in Fig. 13 acts on the two-rotation, two-phase cylinder in Fig. 14, the total thrust increases proportionately due to the two cylinders.

[0095] The two-rotation, three-phase deformable variable spiral cylinder in Fig. 15 is formed by arranging three of the two-rotation, one-phase deformable variable spiral cylinders in Fig. 13 with a phase difference of 120 degrees. When an external rotational force similar to that of the two-rotation, one-phase cylinder in Fig. 13 acts on the two-rotation, three-phase cylinder in Fig. 15, the total thrust is increased proportionately by the three cylinders.

[0096] Figure 16 shows an example of a three-rotation variable spiral. The arrangement of each detailed view is the same as that of the one-rotation variable spiral in Figure 7.

[0097] The formula for the geometric shape of a multi-turn deformed variable spiral with three or more turns is the same as that for a one-turn deformed variable spiral, and is also the same for a spiral whose starting radius is greater than its ending radius and whose shape converges parallel to the central axis of rotation near the end point.

[0098] The cylinder diagram in Figure 17 shows an example of a three-rotation one-phase variable spiral cylinder. The illustrated three-rotation one-phase variable spiral cylinder also has a shape in which the spiral radius and the cylinder inner diameter decrease from the inlet to the outlet in order to increase compression from the inflowing fluid. Here, the positional relationship of each diagram is the same as that of the one-rotation one-phase variable spiral cylinder in Figure 8.

[0099] The three-rotation, two-phase deformable variable spiral cylinder in Figure 18 is formed by arranging two of the three-rotation, one-phase deformable variable spiral cylinders in Figure 17 with a phase difference of 180 degrees. When the same external rotational force as that of the three-rotation, one-phase cylinder in Figure 17 acts on the three-rotation, two-phase cylinder, the total thrust is increased proportionately by the two cylinders.

[0100] The 3-rotation 3-phase deformable variable spiral cylinder in Fig. 19 is formed by arranging three of the 3-rotation 1-phase deformable variable spiral cylinders in Fig. 17 with a phase difference of 120 degrees. When the same external rotational force as that of the 3-rotation 1-phase cylinder in Fig. 17 acts on the 3-rotation 3-phase cylinder, the total thrust increases proportionately due to the three cylinders.

[0101] The above examples of the deformable variable spiral cylinders are only examples of cylinders with circular or elliptical cross sections, but the internal cross sections can be configured in a variety of ways to suit the application, such as polygonal (e.g. triangular, rectangular, pentagonal, hexagonal) or star shapes.

[0102] Figure 20 shows a modified variable spiral cylinder with a trapezoidal cross section. Except that the cross section is not circular, the rest of the configuration is the same and similar to a cylinder with a cylindrical cross section.

[0103] Figure 20A is a front view of a one-turn one-phase trapezoidally deformed variable spiral cylinder, Figure 20B is a right side view, and Figure 20C is an isometric view. Figures 20D, 20E, and 20F show a one-turn two-phase trapezoidally deformed variable spiral cylinder, Figures 20G, 20H, and 20I show a one-turn three-phase trapezoidally deformed variable spiral cylinder, and Figures 20J, 20K, and 20L show a one-turn five-phase trapezoidally deformed variable spiral cylinder.

[0104] The deformed variable spiral cylinder described so far has been described by assuming that the cylinder wall is very thin for the purpose of explanation and showing that the shape of the outside and the inside (empty space) of the cylinder are the same, but in actual applications, the outside shape can have various forms. In other words, it is also possible to cut out the inside of a solid and form a deformed variable spiral cylinder inside the solid. In this way, several devices can be made, some of which are marine propellers, aviation propellers, industrial and domestic nozzles, jet engine casings, etc.

[0105] A propeller to which a deformable variable spiral cylinder is applied will be described with reference to Figs.

[0106] The exterior shape of a propeller is made up of one or more fins, and is expressed as 1-fin when there is one fin, 2-fin when there are two fins, 3-fin when there are three fins, etc. An example shown here is a one revolution, three phase, three fin propeller (hereinafter, one revolution 3P3F Propeller). Also, the number of revolutions of each fin is independent of the number of revolutions of the cylinder. In other words, even if the number of revolutions of the cylinder is one (360 degrees), the number of revolutions of the fins may be less than or more than 360 degrees.

[0107] FIG. 21 is an illustration of a one-rotation 3P3F (3-pase, 3-fin) propeller in which a pin is formed on the outside of a solid bulk and a one-rotation deformable variable spiral cylinder is formed inside it as if it were cut out.

[0108] Based on the front view of Fig. 21C, the plan view of Fig. 21A, the right side view of Fig. 21D, and the bottom view of Fig. 21E are arranged on the upper, right, and lower sides, respectively, and Fig. 21B and Fig. 21F, which are isometric views seen obliquely from the front, are arranged on the upper right and lower right sides. The rear view of Fig. 21G is arranged below the bottom view, and Fig. 21H, which is an isometric view seen obliquely from the rear, is arranged to the right of that.

[0109] The outside of the 3P3F propeller 5000, which rotates counterclockwise when viewed from the front, is formed by three fins (3-fin) 5004, 5005, and 5006, and three cylinders (3-phase) are formed inside it. In directions other than the back surface 5071, the cylinder inlets 5001, 5002, and 5003 can be seen, and at the back surface 5071, the cylinder outlets 5031, 5032, and 5033 can be seen.

[0110] The propeller in FIG. 21 has a hollow 5051 formed along the central axis of rotation of the spiral, and has a structure in which a shaft for transmitting an external rotational force can be sandwiched.

[0111] FIG. 22 shows the external shape of the 3P3F propeller of FIG. 21 together with the cylinder formed therein.

[0112] Figures 22B, 22D, 22F and 22H show three-dimensionally the empty space, i.e., the cylinder, formed inside Figures 22A, 22C, 22E and 22G, respectively, and correspond to a front view, a plan view, a bottom view and a rear view of the cylinder. The three cylinder inlets 5102, 5103, 5014 formed in the left propeller are the same as the three cylinder inlets 5102, 5103, 5014 formed in the cylinder, respectively.

[0113] FIG. 23 shows an enlarged view of the 3P3F propeller and its internal cylinder from FIG.

[0114] In Fig. 23A, each fin 5200 rotates about 220 degrees, whereas in Fig. 23B, each internal cylinder 5210 rotates 360 degrees. In this way, the correlation between the fin rotation speed and the cylinder rotation speed can be used to adjust the flow of fluid into the cylinder, and the internal rotation force, internal pressure, thrust, etc. of the propeller can be adjusted to optimize the angular velocity from the external rotation force.

[0115] FIG. 24 shows a single rotation 3P6F propeller, and the layout in each figure is the same as in FIG. 21.

[0116] Figure 25 shows the side of a 3P6F propeller and its internal cylinder.

[0117] In Fig. 25A, each fin 5400 rotates about 166 degrees, while in Fig. 25B, each internal cylinder 5410 rotates 360 degrees, with the three-phase cylinder rotation rate being greater than the fin rotation rate. Also, the ratio of the outlet section 5411 to the total length is higher than that of the cylinder in Fig. 23. The flow of fluid entering the cylinder can be adjusted using the ratio based on the length of the cylinder outlet section as well as the correlation between the fin rotation rate and the cylinder rotation rate, which affects the internal torque, internal pressure, thrust, etc. of the propeller.

[0118] Figure 26 shows a single rotation 5P5F propeller, and the layout in each figure is the same as in Figure 24.

[0119] Figure 27 shows the side of a 5P6F propeller and its internal cylinder.

[0120] In FIG. 27A, each fin 5600 rotates approximately 440 degrees, while in FIG. 27B, each inner cylinder 5610 rotates 360 degrees, with the number of five phase cylinder rotations being less than the number of fin rotations.

[0121] Figure 28 shows a hollow, single-revolution three-phase propeller without fins. Figure 28A shows three-phase cylinders 6710, 6711, 6712 that constitute the main body of the three-phase propeller, and Figure 28B shows a single-revolution three-phase aircraft propeller with a casing 6720 attached to the outside of the three-phase cylinders.

[0122] Next, various types of nozzles using a modified variable spiral cylinder will be described with reference to Figs.

[0123] Previously, we assumed that a propeller using a modified variable spiral cylinder applies a rotational motion to the central axis of the cylinder from the outside, but here we assume that a water or air current flows in from the nozzle inlet, rather than applying a rotational motion. In particular, we assume that the pressures of the inflowing water and air currents (i.e., water pressure and air pressure) are equivalent. We will also call the nozzle an N-phase modified variable spiral nozzle (N-phase mVHC Nozzle) according to the type of cylinder.

[0124] FIG. 29 shows a one-rotation three-phase modified variable spiral nozzle.

[0125] 29A is a front view, FIG. 29B is a right side view, FIG. 29C is a rear view, and FIGS. 29D and 29E are isometric views from different directions.

[0126] The nozzle is divided into a cylinder 7010 section and a cylinder 7000 section, and the cylinder 7010 is connected to the inlets 7012, 7013, and 7014 of the three-phase deformation variable cylinder. When the fluid 7002 flowing in from the outside is transferred to the cylinder 7004 through the space 7001 inside the cylinder, compression and condensation occur inside the cylinder, and the fluid is ejected through the outlets 7021, 7022, and 7023.

[0127] The structure of the multiple cylinders 7004 provided in the cylinder 7000 section is the modified variable spiral cylinder described above.

[0128] FIG. 30A is an external view of FIG. 29E, and FIG. 30B shows a three-dimensional view of the cylinder formed inside.

[0129] While the cylinder 7010 and the section of cylinder 7000 in FIG. 30A are both formed from the material that constitutes the nozzle, the cylindrical interior space 70010 and the individual cylinders 7004 in FIG. 30B form the empty space within the material.

[0130] On the other hand, the outer wall of the cylinder at the rear surface 7101 of the nozzle is relatively thick, in order to prevent the cylinder outlet from popping out due to a large pressure being applied to the outlet.

[0131] 31 and 32 show a one-rotation five-phase modified variable spiral nozzle.

[0132] The layout of each diagram in FIG. 31 is the same as that in FIG. 29, and the layout of each diagram in FIG. 32 is the same as that in FIG.

[0133] Figures 33A and 33B show a three-phase nozzle without a cylindrical section in isometric projections from different directions. The empty space inside the three-phase nozzle is formed by a three-phase cylinder.

[0134] Various application examples using the modified variable spiral cylinder, propeller and nozzle of Figs. 34 to 39 are shown.

[0135] First, FIG. 34 is an example diagram in which the one-rotation 3P3F propeller 5000 of FIG.

[0136] FIG. 35 is an illustrative diagram of the single rotation 3P3F propeller 5000 of FIG.

[0137] Fig. 36 is an exemplary diagram in which the one-rotation three-phase propeller of Fig. 28 is applied to a drone 8200. A three-phase propeller consisting of a cylinder 8201 and a casing 8202 is connected to each power transmission shaft 8203 of the drone 8200.

[0138] 37 is a diagram showing an example in which a one-rotation three-phase cylinder is applied to a jet engine 8300. The central axis of the three-phase cylinder is connected to the central axis of the jet engine and rotates like a jet engine. When airflow 8310 flowing into the jet engine ignites and explodes inside the engine 8320 and is ejected from the jet engine outlet, a part or all of the ejected airflow flows into the three-phase cylinder 8330 to generate additional thrust and ejection force.

[0139] 38 is a diagram illustrating an example in which a one-rotation modified variable spiral three-phase nozzle 8401 having a cylindrical section and a cylinder section is applied to a Palton wheel 8400 for hydroelectric power generation. Water flowing into the nozzle 8401 through a pipe 8402 is sprayed from the outlet of the nozzle 8401 and impacts a bucket 8403 of the Palton wheel 8400 to transmit power.

[0140] Fig. 39 shows an example in which a one-rotation modified variable spiral three-phase nozzle without a cylindrical section is applied to a jet engine 8500. Here, unlike Fig. 38, the three-phase nozzle is fixed so as not to rotate with the central axis. When airflow 8510 flowing into the jet engine ignites and explodes inside the engine 8520 and is ejected from the jet engine outlet, a part or all of the ejected airflow flows into the three-phase cylinder 8530 to generate additional thrust and ejection force.

[0141] So far, the deformable variable spiral and the deformable variable spiral cylinder using the same have been explained using various examples.

[0142] The modified variable spiral cylinder (mVHC) of the present invention has the following features:

[0143] (1) A cylinder is a hollow tube that connects an "inlet" and an "outlet," and the parts other than the inlet and outlet are closed from the outside. Therefore, when a rotational force is applied, the force generated by the rotational force is converted into linear motion without allowing the water or air flow that has flowed into the outlet to escape, and when pressure is applied, the force increased by the rotational force inside the cylinder is converted into linear motion.

[0144] (2) A deformable variable spiral is formed toward the center of the cylinder.

[0145] (3) The cylinder has a cylindrical shape tapered from the cylinder inlet toward the outlet, and the cross-sectional area on the inlet side is larger than the cross-sectional area on the cylinder outlet side.

[0146] (4) One or more identical cylinders are formed so as to be arranged around a central axis with a predetermined phase difference.

[0147] (5) A fluid, i.e., water flow, water current or air flow, can enter the cylinder through its inlet and exit through its outlet.

[0148] (6) The inlet of the cylinder is shaped at an angle to maximize fluid inflow.

[0149] (7) As it approaches the tip of the cylinder, it becomes parallel to the cylinder's central axis, and the cylinder outlet is formed at an angle so that the fluid flows out parallel to the cylinder's central axis.

[0150] (9) An external force acts on the deformable variable spiral cylinder, generating a fluid flow at the cylinder inlet. This force can be the rotational motion of the cylinder or pressure applied to the fluid. When a force is applied to rotate the cylinder around the central axis of rotation of the cylinder, the fluid flows into the cylinder inlet due to the rotational force of the cylinder. The pressure applied to the fluid toward the cylinder inlet includes water pressure or air pressure acting on the cylinder inlet.

[0151] (10) When a fluid flows into the inlet of a cylinder, it passes through the spiral cylinder interior, generating an internal rotational force, and the pressure of the fluid increases due to the phenomenon that the inner diameter of the cylinder narrows, causing the compressed fluid to be ejected at the cylinder outlet, generating thrust in the cylinder. There is no loss of water or air flow within a sealed cylinder, and the internal rotational force can be fully maintained, and thrust and ejection force are obtained by converting the internal rotational force into linear motion parallel to the central axis of the cylinder or nozzle.

[0152] (11) The first characteristic of a propeller using a modified variable spiral cylinder (mVHC) is the correlation of thrust resulting from the difference between the number of cylinders N and the number of fins F. By adjusting the numbers of each (N, F), it is possible to obtain the most ideal thrust for the external rotational force.

[0153] (12) The second feature of the propeller is the correlation of the thrust resulting from the difference (i.e., phase difference) between the rotation speed (or phase) of the cylinder and the rotation speed (or phase) of the fin. In other words, when the phase of the cylinder per unit length is set to 1, by making the phase of the fin smaller or larger, it is possible to obtain the most ideal thrust for the external rotational force by utilizing the phase difference between the cylinder and the fin.

[0154] (13) The modified variable spiral cylinder is defined as the ratio of (i) the height and width of the cylinder, (ii) the number of rotations of the cylinder within the total height, (iii) the distance between pitches, (iv) the ratio of the inlet and outlet areas of the cylinder, and (v) the length of the straight outlet section.

[0155] (14) The height and width of a deformed variable spiral cylinder are defined as the set of the radius at the starting point and the radius at the end point of the two-dimensional spiral, as well as the projection points and projection lines.

[0156] (15) The modified variable spiral cylinder can be used for either water flow or air flow.

[0157] (16) By determining whether the force that drives the cylinder is rotational force or pressure, and adjusting the ratios of (i), (ii), (iii), (iv), and (v) above, the optimal thrust or ejection force can be obtained.

[0158] (17) It can be used in a variety of applications that require thrust in various industrial sectors. Typical examples of applications include propellers and nozzles.

[0159] In the above description, the present invention has been described with reference to the embodiments shown in the drawings so that those skilled in the art can easily understand and reproduce the present invention.
