Description

【Technical Field】 【0001】 The present invention relates to a deformed variable spiral cylinder obtained by deforming and applying a variable spiral, and a propeller and a nozzle using the same. 【Background Art】 【0002】 As a prior art for constructing a propulsion device such as a propeller using a spiral, there is a registered utility model No. 20-0278161 "Spiral Blade Propulsion Device for Ships" registered and announced on June 20, 2020. The propulsion part of the propulsion device shown in FIG. 1 is formed with a spiral blade 44 welded longitudinally on a rotating shaft 43 penetrating through the inside 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 rotating support means 70. After the spiral blade 44 rotates and seawater flows into the inflow conduit 32, at the same time, the tapered conduit 51 is pressurized. 【0003】 As another prior art for constructing a propulsion device such as a propeller using a spiral, as disclosed in the registered patent No. 10-1703873 "Spiral Upper Half Drive Cylindrical Propulsion Body" registered and announced on February 7, 2017, there is a case where a spiral blade or fin is formed on the outer peripheral surface of a cylindrical cylinder extending in one direction and applied to an amphibious vehicle. The cylindrical propulsion body shown in FIG. 2 is a method in which spiral propulsion protrusions 121 are provided on the outer surface of a cylindrical propulsion member 120 formed long in the front-rear direction to generate propulsion force. 【0004】 However, all of the above prior arts are those in which a spiral blade is attached to the outside of a cylinder, that is, a cylinder, and the cylinder itself is not formed in a spiral shape. Within the scope known to the inventor of the present invention, an invention that attempts to obtain propulsion force by forming a cylinder in a spiral shape inside the main body of a certain propulsion body has not been proposed conventionally. 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0005】 The present invention aims to provide a cylinder in which an empty space is formed inside the main body. 【0006】 The present invention aims to provide a propeller and nozzle in which a variable spiral cylinder is formed inside the main body. 【0007】 The present invention aims to provide a cylinder that can adjust the internal flow of fluid by adjusting the ratio of the fuselage section to the outlet section, the rotation speed and the number of internal cylinders, the number of external pins and internal cylinders, and a propeller and nozzle using the same. 【0008】 The present invention aims to provide a means of transport such as ships, submarines, aircraft, and drones to which the above-mentioned cylinders, propellers, nozzles, etc., are applied. [Means for solving the problem] 【0009】 The variable spiral cylinder of the present invention is fundamentally 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 a common spring. The elements that define a spiral are its radius, pitch, and height. A variable spiral is a spiral with modified radius and period, and in this invention, it is characterized by a configuration in which the radius at the lower end decreases as it goes upwards. A variable spiral (mVHC) is a further modification of the variable spiral, the most significant being that the exit section of the variable spiral is modified to be approximately parallel to the rotational central axis. 【0010】 A spiral cylinder according to one embodiment of the present invention is a spiral cylinder having a hollow cylindrical shape having a predetermined radius with respect to a cylinder centerline that rotates spirally with respect to a rotational axis, wherein the cylindrical shape has a configuration that rotates spirally along the cylinder centerline, the cylindrical shape has an inlet for fluid inflow and an outlet for fluid outflow, and the outlet portion of the cylindrical shape extends parallel to the rotational axis. 【0011】 Furthermore, the diameter of the inlet is larger than the diameter of the outlet, and the cylindrical shape is characterized in that its diameter gradually decreases as it moves from the inlet side to the outlet side. 【0012】 Furthermore, the cylindrical shape is characterized in that the distance between the cylinder centerline and the rotational axis gradually decreases as one moves from the inlet side to the outlet side. 【0013】 Another embodiment of the present invention is a spiral cylinder comprising a plurality of basic type cylinders that rotate spirally around the same rotational axis, wherein each basic type cylinder has an inlet for fluid inflow and an outlet for fluid outflow, the cylinder body between the inlet and the outlet is sealed, the number of spiral rotations relative to the total length of the spiral cylinder is M (where M is a positive real number), and the number of basic type cylinders is N (where N is a natural number). 【0014】 Furthermore, the N basic cylinders are characterized by being spaced apart from each other in the same phase. 【0015】 Furthermore, the basic cylinder is characterized in that its diameter gradually decreases as it moves from the inlet side to the outlet side, and the outlet portion of the basic cylinder is provided with an outlet section in which the basic cylinder extends parallel to the rotational axis. 【0016】 Furthermore, the cross-section of the basic cylinder is characterized by being circular or polygonal. 【0017】 A propeller according to one embodiment of the present invention is characterized in that it is composed of a spiral cylinder and a casing surrounding the spiral cylinder. 【0018】 A propeller according to another embodiment of the present invention comprises a main body having F pins and N cylinders formed within the main body, wherein F and N are natural numbers, and the cylinders are realized in empty spaces. 【0019】 Each cylinder is embodied in a free space having a predetermined radius with reference to a cylinder center line that spirally rotates with respect to the rotation center axis of the propeller. 【0020】 Each cylinder also includes an inlet for the inflow of fluid and an outlet for the outflow of the fluid, and the diameter of the cylinder gradually decreases from the inlet side toward the outlet side. 【0021】 The distance between the cylinder center line and the rotation center axis also gradually decreases from the inlet side toward the outlet side. 【0022】 An outlet section in which the cylinder extends parallel to the rotation center axis is provided at the outlet of each cylinder. 【0023】 The N cylinders are also spaced apart from each other in the same phase. 【0024】 (N, F) is also one of (3, 3), (3, 6), and (5, 5). 【0025】 On the other hand, a nozzle according to an embodiment of the present invention is a nozzle including a cylinder part including a plurality of basic cylinders that spirally rotate with respect to the same rotation center axis, and a cylindrical part coupled to the cylinder part. The basic cylinder includes an inlet for the inflow of fluid from the cylindrical part 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 diameter of the basic cylinder also gradually decreases from the inlet side toward the outlet side. 【0027】 An outlet section extending parallel to the rotation center axis is provided at the outlet of the basic cylinder. 【0028】 Further, 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 toward the outlet side. 【Advantages of the Invention】 【0029】 According to the present invention, a cylinder having a free space formed inside the main body is provided. 【0030】 Further, according to the present invention, a propeller and a nozzle in which a deformable variable spiral cylinder is formed inside the main body are provided. 【0031】 Further, according to the present invention, transportation means such as ships, submarines, aircraft, drones, etc. to which the cylinder, propeller, nozzle, etc. are applied can be provided. 【0032】 On the other hand, by adjusting one or more of the ratio of the outlet section of the deformable variable spiral cylinder of the present invention, the correlation between the rotational speed of the fins and the cylinder, the correlation between the number of fins and the cylinder, etc., the flow of the fluid inside the cylinder and the thrust at the outlet can be controlled. 【0033】 A major difference between the deformable variable spiral cylinder (mVHC) of the present invention and an existing conventional cylindrical cylinder is the cohesive force of water flow and air flow. The process is as follows. First, the water flow or air flow that has flowed through the inlet section of the deformable variable spiral cylinder due to external rotational movement or external pressure is sealed and enters the trunk section at a high speed and increasing pressure according to the shape of the cylinder that becomes narrower and narrower. Second, maintaining a high speed and high pressure, an internal rotational force is generated inside the trunk section by the water flow and air flow entering the trunk section. The internal rotational force and pressure continue to be maintained due to the water flow and air flow continuously flowing into the inlet section. Third, this internal rotational force and pressure increase more and more due to the shape of the cylinder whose diameter becomes narrower and narrower, and the lost water flow and air flow completely aggregate in the outlet section and switch to a linear thrust and jet force parallel to the central axis. 【0034】 In other words, when water or air flows into the variable spiral cylinder of the present invention, it naturally switches to linear motion after undergoing rotational motion using the spiral, thereby enabling the incoming water or air to be converted into thrust or jet force completely parallel to the central axis. 【0035】 While the principle of a variable spiral (mVHC) propeller and nozzle is essentially the same as that of a cylinder, the difference lies in the fact that in the case of a propeller, external rotational force generates water pressure or air pressure in the cylinder, 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 continuously flowing into the nozzle inlet section sustain the internal rotational force of the nozzle. This pressure increases further due to the increasingly narrow cylinder shape, and without resistance and without loss of water or airflow, it is completely condensed in the outlet section and converted into linear thrust and jet force parallel to the central axis.

[Modes for carrying out the invention] 【0037】 A variable-deformation spiral cylinder is fundamentally based on a spiral in space. A spiral starts at a point in space, rotates around a central axis (hereinafter referred to as the rotation axis), traces a trajectory, and has a shape similar to a common spring. The elements that define a spiral are its radius, pitch, and height. Generally, when a spiral is projected onto the two-dimensional xy-plane, its shape is a circle, and when a spiral is projected onto the xz-plane or yz-plane, its shape is a sine curve. The pitch can simply be described as 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 a spiral in which the radius and period are deformed. A variable spiral exhibits a form in which the radius at the lower end decreases as it goes upwards. That is, when a variable spiral is projected from above onto a two-dimensional plane (xy plane), its shape becomes a spiral. The deformable variable spiral (mVHC) in this invention is a further deformation of the above variable spiral. Its most distinctive feature is that the exit section of the variable spiral is deformed so that it is almost parallel to the central axis. 【0039】 A cylinder incorporating such a variable-deformation spiral can naturally convert the water and airflow entering the cylinder into rotational motion through that rotational motion. Furthermore, by setting the angle and shape so that the maximum water and airflow enters the cylinder at the inlet section, this leads to an increase in internal pressure, resulting in a more powerful conversion to linear motion. In addition, with a variable-deformation spiral cylinder, even when closed except at the inlet and outlet, there is no loss of water or airflow when the water or airflow is converted from rotational motion to linear motion, allowing the water or airflow to be converted into thrust or jet force completely parallel to the central axis. 【0040】 The following sections will explain in detail, using the attached diagrams, everything from the principle of spirals to application examples of variable-deformability spiral cylinders. 【0041】 Figure 3 shows a helix and consists of detailed views of Figures 3A to 3L projected in different directions. 【0042】 A spiral is a continuous curve in three-dimensional space that rotates around a fixed axis. A spiral is generally represented using the following parametric equation. x(t) = a·cos(t) y(t) = a·sin(t) z(t) = b·t 【0043】 In Figure 3A, the spiral 1000 rotates while progressing from the starting point 1002 to the ending point 1003, with a constant interval, i.e., radius 1004, around the rotational axis 1001. The radius 1004 of the spiral corresponds to 'a' in the parametric equation, and the pitch of the spiral (=2π·b) represents the distance between peaks and valleys on the vertical axis (z-axis), and corresponds to the distance from one point on the spiral to other points located on the same z-axis, with the vertical axis (z-axis) as the reference. 【0044】 The spiral 1000 in Figure 3A rotates a total of one time around the rotational axis 1001 and has a constant radius (a) and a constant pitch (2π·b). In the case of a one-rotation spiral, the height and pitch of the spiral are the same. The spiral 1007 in Figure 3B is a plan view of the spiral 1000 in Figure 3A, which has a radius (a) 1008, and it can be seen that the shape of the spiral 1000 viewed from above is a circle. The spiral 1010 in Figure 3C corresponds to a side view of the spiral 1000 in Figure 3A rotated by 90 degrees, and its shape is a sine curve with a rotational axis 1011 (1001 in Figure 3A), radius 1012 (1004 in Figure 3A), and pitch 1013 (1005 in Figure 3A). 【0045】 The spirals 1020, 1027, and 1030 in Figures 3D, 3E, and 3F are configured to rotate twice around the rotation axis 1021, from the starting point 1022 to the ending point 1023. Similar to the spiral sets in Figures 3A, 3B, and 3C, in the spiral sets of 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 each spiral in each spiral set in Figure 3 applies similarly to the other spiral sets described below. 【0046】 Figures 4A, 4B, 4C, and 4D, which are detail diagrams of Figure 4, show spiral cylinders corresponding to the spirals in Figures 3A, 3D, 3G, and 3J, respectively. 【0047】 In Figure 4A, the spiral cylinder 1100 rotates once from one end 1105 to the other end 1102 around the rotational axis 1101, and has a radius 1104 (hereinafter referred to as the cylinder radius) relative to the cylinder centerline 1103, and is a hollow cylindrical spiral structure. 【0048】 The spiral cylinder 1120 in Figure 4B is formed by rotating twice around the rotational axis 1121 from one end 1125 to the other end 1122, and has a hollow cylindrical spiral structure with a cylinder radius 1124 relative to the cylinder centerline 1123. 【0049】 The spiral cylinder 1140 in Figure 4C is formed by rotating three times around the rotational axis 1141 from one end 1145 to the other end 1142, and has a hollow cylindrical spiral structure with a cylinder radius 1144 relative to the center line 1143. 【0050】 The spiral cylinder 1160 in Figure 4D is formed by rotating four times around the rotational axis 1161 from one end 1165 to the other end 1162, and has a hollow cylindrical spiral structure with a cylinder radius 1164 relative to the center line 1163. 【0051】 In this way, a spiral cylinder that rotates n times can be generalized. 【0052】 Figure 5 shows a variable helix and consists of detailed views 5A to 5L projected in different directions. The arrangement of the detailed views in Figure 5 is the same as in Figure 3. 【0053】 A variable spiral rotates around a central axis as a continuous curve in three-dimensional space, but its radius and pitch gradually increase or decrease as it rotates. A variable spiral is generally represented using the following parametric equation. x(t) = a·f(t)·cos(t) y(t) = a·f(t)·sin(t) z(t)=b·f(t) 【0054】 In Figure 5A, the variable spiral 2000 rotates around the rotational axis 2001, progressing from the starting point 2001 to the ending point 2003, with the radius decreasing and the pitch increasing as it moves upward. The spiral radius 1004 corresponds to a·f(t), and the spiral pitch corresponds to 2π·b·f(t). 【0055】 The spiral sets 2000, 2005, and 2008 in Figures 5A, 5B, and 5C rotate a total of one time around the rotational axis 1001 (n=1), so the height h and pitch p of the spirals are the same. In Figure 5B, the radius 2006 at the starting point 2002 of spiral 2005 is larger than the radius 2007 at the ending point 2003. Figure 5B is a plan view of Figure 5A, and it can be confirmed that the shape of spiral 2000 viewed from above is the trajectory of spiral 2005. Spiral 2008 in Figure 5C corresponds to a side view of spiral 2000 in Figure 5A rotated 90 degrees, and shows the central axis 2009, decreasing radii 2010 and 2011, and a pitch 2012 equal to the height. 【0056】 The spirals 2020, 2025, and 2028 in Figures 5D, 5E, and 5F are configured to rotate twice from the starting point 2022 to the ending point 2023 around the rotational axes 2021 and 2029. The total height 2024(h) is equal to the sum of the magnitudes of the first pitch 2032 including the starting point and the second pitch 2033 including the ending point. As you move from the starting point 2022 towards the ending point 2023, the radius decreases from the starting radii 2026 and 2030 to the end radii 2027 and 2031, while the pitch increases from the first pitch 2032 to the second pitch 2033. 【0057】 In the spiral sets of Figures 5G, 5H, and 5I, spirals 2040, 2045, and 2048 are configured to rotate three times, and the total height 2044(h) is equal to the sum of the sizes of the first pitch 2052, the second pitch 2053, and the third pitch 2054. The radius and pitch sizes are variable, as in Figures 5D, 5E, and 5F. 【0058】 In the spiral sets of Figures 5J, 5K, and 5L, spirals 2060, 2065, and 2068 are configured to rotate four times, with a total height of 2064 equal to the sum of the sizes of the first to fourth pitches 2072 to 2075, and the radius and pitch are variable in the same manner as in Figures 5D, 5E, and 5F. 【0059】 The variable spiral applied to this invention is a variable spiral that rotates n times, and the total height h is equal to the sum of the pitches p1...pn included in the spiral, and the radius decreases along the direction of travel, and the pitch increases. This can be generalized to a variable spiral that rotates n times. 【0060】 The above description of a variable spiral explains the case where the radius and pitch increase along the direction of spiral progression. However, variable spirals can also include cases where both the radius and pitch decrease, where one of the radius and pitch is fixed at a constant value and only the other increases or decreases, and where one of the radius and pitch increases and the other decreases. Such concepts are obvious to those skilled in the art, so a detailed explanation is omitted. 【0061】 Figures 6A, 6B, 6C, and 6D, which are detailed views of Figure 6, show variable spiral cylinders corresponding to the spirals in Figures 5A, 5D, 5G, and 5J, respectively. 【0062】 In Figure 6A, the variable spiral cylinder 2100 rotates once from one end 2105 to the other end 2102 around the rotational axis 2101, and has a hollow cylindrical spiral structure with a constant radius 2104 relative to the cylinder centerline 2103. 【0063】 The variable spiral cylinder 2120 in Figure 6B rotates twice from one end 2125 to the other end 2122 around the rotational axis 2121, and has a hollow cylindrical spiral structure with a constant radius 2124 relative to the cylinder centerline 2123. 【0064】 The variable spiral cylinder 2140 in Figure 6C rotates three times around the rotational axis 2141, from one end 2145 to the other end 2142. It is a hollow cylindrical spiral structure with a constant radius 2144 relative to the cylinder centerline 2143. 【0065】 The variable spiral cylinder 2160 in Figure 6D rotates four times around the rotational axis 2161 from one end 2165 to the other end 2162, and has a hollow cylindrical spiral structure with a constant radius 2164 relative to the cylinder centerline 2163. 【0066】 In this way, a spiral cylinder that rotates n times can be generalized. 【0067】 Figure 7 shows a variable-deformability spiral according to the present invention. The spiral set in detail figures 7A to 7F shows an example of a variable-deformability spiral of one rotation. 【0068】 The features of the variable-deformability spiral proposed in this invention are that the starting radius is larger than the end radius, and that the endpoints of the spiral do not show a rotational trajectory with respect to the rotational center axis, but converge to a straight line that is almost parallel to the center 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 made to ensure linear convergence near the endpoint. 【0069】 Based on the front view in Figure 7C, the top view in Figure 7A, the right side view in Figure 7D, and the bottom view in Figure 7E are positioned above, to the right, and below, respectively. The isometric projections in Figure 7B and 7F are positioned on the upper right and lower right sides, respectively. 【0070】 Referring to the aforementioned drawings, the deformable spirals 3000, 3003, 3006, 3009, 3012, and 3015 proceed from the starting point of the spiral section toward the endpoints of the semi-linear sections 3005, 3008, 3011, 3014, and 3017, with the rotational axis 3004, 3007, 3010, 3013, and 3016 as reference points, with the starting radius 3001 being greater than the end radius 3002, and the ends of the spirals being almost in a straight line parallel to the rotational axis. 【0071】 Each detailed view in Figure 8 shows the variable-velocity spiral cylinder (mVHC) according to the present invention. 【0072】 A variable-deformability spiral cylinder is a cylinder to which the variable-deformability spiral geometry of the present invention is applied. If there is one cylinder around the rotational axis, it will be called a one-phase cylinder; if there are two, it will be called a two-phase cylinder; if there are three, it will be called a three-phase cylinder; and if there are N, it will be called an N-phase cylinder, and so on. 【0073】 Figure 8 shows a variable spiral cylinder with one phase of deformation per revolution. The top view (Figure 8A), right side view (Figure 8D), bottom view (Figure 8E), and rear view (Figure 8G) are positioned above, to the right, below, and at the very bottom of the front view (Figure 8C), respectively. Figures 8B and 8F, which are isometric views taken obliquely from the front, are positioned on the upper right and lower right sides, respectively. The isometric view in Figure 8H is an isometric view taken obliquely from the rear. For reference, the same reference numerals are used for identical components, and this is also the case for the remaining figures below. 【0074】 The variable spiral cylinder 3020 in Figure 8 is designed such that the radius at the inlet side, i.e., the starting radius, is greater than the radius at the outlet side, i.e., the end radius. Here, the pitch can be designed to be constant, increasing, or decreasing along the spiral direction of travel. 【0075】 The variable-deformability spiral cylinders shown in Figures 8A to 8H are generated with the variable-deformability spiral 3022 as the cylinder centerline, and the variable-deformability spiral 3022 and the variable-deformability spiral cylinder 3020 have a shape that rotates spirally with respect to the rotational axis 3021. The variable-deformability spiral cylinder is characterized by having a shape that narrows from the inlet 3023 side toward the outlet 3025, and near the outlet, the cylinder moves in a direction parallel to the rotational axis. 【0076】 As clearly shown in the right side view of Figure 8D, the variable-deformation spiral cylinder can be distinguished into a fuselage section 3036 and an exit section 3037. The fuselage section 3036 is the section in which the cylinder spirally rotates along the spiral centerline, and the exit section 3037 is the section near the exit of the spiral in which it is straightened in a direction parallel to the rotational axis of the spiral. 【0077】 Next, we will explain how a variable-deformation spiral cylinder can be applied to a propulsion system. 【0078】 First, let's assume that an external rotational force is applied to the rotational center axis 3021 of the variable spiral cylinder with one phase deformation per revolution shown in Figure 8, causing the cylinder to rotate in a constant direction. 【0079】 In Figures 8A to 8H, the rotation direction of the variable-deformability spiral cylinder is indicated by an arrow. Using the front view in Figure 8C as a reference, the variable-deformability spiral cylinder 3020 rotates counterclockwise 3024 with respect to the rotation center axis 3021, and in the rear view in Figure 8G, it rotates clockwise. As a result, in the top view in Figure 8A, the inlet 3023 of the variable-deformability spiral cylinder rotates in a direction that penetrates the ground, and in the bottom view in Figure 8E, the inlet 3023 of the variable-deformability spiral cylinder rotates in a direction that penetrates the ground and exits. 【0080】 When the variable-deformability spiral cylinder is placed in a fluid, the rotational motion of the variable-deformability spiral cylinder causes fluid such as water or air to flow into the inlet 3023, move along the sealed cylinder, and then exit through the outlet 3025. Furthermore, when fluid flows into the inlet of the variable-deformability spiral cylinder due to an external rotational force, the incoming fluid passes through the body section of the variable-deformability spiral cylinder, generating an internal rotational force. In addition, the phenomenon of the inner diameter of the cylinder narrowing as it moves towards the outlet generates pressure in the fluid, causing the compressed fluid to be ejected at the outlet of the variable-deformability spiral cylinder, generating thrust. This principle can be used to utilize the variable-deformability spiral cylinder as a propulsion system. 【0081】 Next, we will describe a multiphase (N-phase) variable spiral cylinder in which two or more cylinders are coupled together, using Figures 9 to 11. The relative arrangement of the detailed diagrams in Figures 9 to 11 is the same as in Figure 8. 【0082】 First, the variable spiral cylinder 3100 with two phases of deformation per revolution, shown in Figure 9, is constructed by alternately arranging two variable spiral cylinders with one phase of deformation per revolution. It has a structure in which two variable spiral cylinders of the same shape are arranged with a 180-degree phase difference via a central rotation axis 3101. The inlets 3102 and 3103 face in opposite directions from each other, and the cylinder rotates counterclockwise 3104. 【0083】 In the two-phase variable spiral cylinder shown in Figure 9, the inner diameter of each cylinder narrows from the inlet side to the outlet side, and near the outlet, it moves in a direction parallel to the rotation axis of the cylinder, with each outlet 3131 and 3132 facing the same direction. Overall, it can be divided into body sections 3141 and 3142 and an outlet section 3143, and the body section can be further subdivided into an inlet section 3141 and a body section 3142. 【0084】 Even in a two-phase cylinder per revolution, when fluid flows into the cylinder inlet due to an external rotational force, it passes through the cylinder body section, causing internal rotational force and compression, and is ejected from the outlet, generating thrust. If the same external rotational force as in a one-phase cylinder per revolution acts on a two-phase cylinder per revolution, the overall thrust increases proportionally due to the two cylinders. 【0085】 Next, we will explain a variable spiral cylinder with three phases of deformation per revolution, which is formed by arranging three variable spiral cylinders with one phase of deformation per revolution alternately with a 120-degree phase difference, using Figure 10. 【0086】 In Figure 10, each inlet is positioned at a 120-degree angle, and the cylinder rotates counterclockwise. Each cylinder of the three-phase variable spiral cylinder also narrows in diameter from the inlet to the outlet, and near the outlet, it moves in a direction parallel to the cylinder's rotation axis, allowing it to be divided into a body section and an outlet section. 【0087】 The thrust generation process for a three-phase cylinder per revolution is the same as that for one-phase and two-phase cylinders; when the same external rotational force is applied, the total thrust increases proportionally through the three cylinders. 【0088】 Next, Figure 11 shows a variable spiral cylinder with five phases per revolution, arranged alternately with a 72-degree phase difference between each of the five variable spiral cylinders that each revolution produces one phase of deformation. The operating mechanism of the variable spiral cylinder with five phases per revolution is the same as that of the other multi-phase variable spiral cylinders described above. However, the inner diameters of the inlet and outlet of the five individual cylinders applied to the variable spiral cylinder with five phases per revolution are smaller than those of the single-phase cylinder described above. 【0089】 Here, we will explain the multi-turn variable spiral cylinder using Figures 12 to 19. 【0090】 To begin with, regarding multi-turn variable spiral deformation, a multi-turn variable spiral deformation is the same as a single-turn variable spiral deformation in that, except that it is a spiral that rotates two or more times, the starting radius is larger than the ending radius, and the fluid is discharged parallel to the rotational axis, so it converges to a straight line parallel to the rotational axis at the ends of the cylinder. 【0091】 Figure 12 shows an example of a two-rotation variable spiral. The arrangement of the detailed diagrams is the same as in the case of the one-rotation variable spiral in Figure 7. 【0092】 Even in the case of the 2-rotation variable spiral 3400, the equation describing the geometric shape is the same as in the case of the 1-rotation variable spiral, and the deformation applied so that the starting radius 3401 is larger than the end radius 3402 and converges parallel to the rotational center axis near the endpoint 3405 is also the same. 【0093】 Figure 13 shows an example of a two-turn, one-phase variable spiral cylinder with a two-turn variable spiral design. The illustrated two-turn, one-phase variable spiral cylinder has a shape in which the radius of the spiral and the inner diameter of the cylinder decrease from the inlet to the outlet in order to increase the compression from the incoming fluid. Here, the arrangement of each figure is the same as in the case of a one-turn, one-phase variable spiral cylinder. 【0094】 The two-rotation, two-phase variable spiral cylinder in Figure 14 is formed by arranging two two-rotation, one-phase variable spiral cylinders from Figure 13 with a 180-degree phase difference. When the same external rotational force as the two-rotation, one-phase cylinder in Figure 13 acts on the two-rotation, two-phase cylinder in Figure 14, the overall thrust increases proportionally due to the two cylinders. 【0095】 The two-rotation, three-phase variable spiral cylinder in Figure 15 is formed by arranging three two-rotation, one-phase variable spiral cylinders from Figure 13 with a 120-degree phase difference. When the same external rotational force as the two-rotation, one-phase cylinder in Figure 13 acts on the two-rotation, three-phase cylinder in Figure 15, the overall thrust increases proportionally due to the three cylinders. 【0096】 Figure 16 shows an example of a 3-rotation variable spiral. The arrangement of each detail is the same as that of the 1-rotation variable spiral in Figure 7. 【0097】 Even in the case of a multi-turn variable spiral with three or more rotations, the equation describing the geometric shape is the same as that for a single-turn variable spiral, and it is also the same even when the starting radius is larger than the ending radius and deformation is applied so that it converges parallel to the rotational axis near the endpoint. 【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 radius of the spiral and the inner diameter of the cylinder decrease from the inlet to the outlet in order to increase the compression from the incoming fluid. Here, the arrangement of each figure is the same as in the case of the one-rotation, one-phase variable spiral cylinder in Figure 8. 【0099】 The 3-rotation, 2-phase variable spiral cylinder in Figure 18 is formed by arranging two 3-rotation, 1-phase variable spiral cylinders from Figure 17 with a 180-degree phase difference. When the same external rotational force as the 3-rotation, 1-phase cylinder in Figure 17 acts on the 3-rotation, 2-phase cylinder, the overall thrust increases proportionally due to the two cylinders. 【0100】 The 3-rotation, 3-phase variable spiral cylinder in Figure 19 is constructed by arranging three 3-rotation, 1-phase variable spiral cylinders from Figure 17 with a 120-degree phase difference. When the same external rotational force acts on the 3-rotation, 3-phase cylinder as on the 3-rotation, 1-phase cylinder in Figure 17, the overall thrust increases proportionally due to the three cylinders. 【0101】 The above examples of variable-form spiral cylinders only show cases where the cross-section is circular or elliptical, but the internal cross-section can be configured in various ways depending on the application, such as with polygons like triangles, squares, pentagons, and hexagons, or even star shapes. 【0102】 Figure 20 shows a variable-deformation spiral cylinder with a trapezoidal cross-section. Except for the fact that the cross-section is not circular, the remaining configuration is the same as, or similar to, a cylinder with a cylindrical cross-section. 【0103】 Figure 20A is a front view of a one-phase trapezoidal variable spiral cylinder per revolution, Figure 20B is a right side view, and Figure 20C is an equiaxial projection view. Figures 20D, 20E, and 20F show a two-phase trapezoidal variable spiral cylinder per revolution, Figures 20G, 20H, and 20I show a three-phase trapezoidal variable spiral cylinder per revolution, and Figures 20J, 20K, and 20L show a five-phase trapezoidal variable spiral cylinder per revolution. 【0104】 The variable-deformability spiral cylinders described so far have been explained by assuming that the cylinder walls are very thin and that the shape of the cylinder's exterior and interior (empty space) are identical. However, in actual applications, the exterior shape can take on various forms. In other words, it is also possible to cut out the interior of a solid and form a variable-deformability spiral cylinder inside the solid. Several devices can be made in this way, some of which include marine propellers, aviation propellers, industrial and household nozzles, and jet engine casings. 【0105】 A propeller incorporating a variable spiral cylinder will be described with reference to Figures 21 to 28. 【0106】 The external shape of a propeller consists of one or more fins. A propeller with one fin is called a 1-fin, two fins a 2-fin, three fins a 3-fin, and so on. An example shown here is a 1-revolution, 3-phase, 3-fin propeller (hereinafter referred to as the 1-revolution 3P3F Propeller). Furthermore, the rotational speed of each fin is independent of the rotational speed of the cylinder. That is, even if the cylinder rotates once (360 degrees), the rotational speed of the fins may be less than or greater than 360 degrees. 【0107】 Figure 21 is an illustrative diagram of a 3-pase, 3-fin propeller with a pin formed on the outside of a solid bulk, and a variable spiral cylinder that can be deformed by one rotation formed inside the pin as if it were cut out. 【0108】 Based on the front view in Figure 21C, the top view (Figure 21A), the right side view (Figure 21D), and the bottom view (Figure 21E) are positioned above, to the right, and below, respectively. Figures 21B and 21F, which are isometric projections taken obliquely from the front, are positioned on the upper right and lower right sides, respectively. Below the bottom view is the rear view (Figure 21G), and to its right is the isometric projection (Figure 21H), taken obliquely from the rear. 【0109】 The 3P3F propeller 5000, which rotates counterclockwise when viewed from the front, has three fins (3-fin) 5004, 5005, and 5006 on its exterior, and three cylinders (3-phase) are formed inside. The cylinder inlets 5001, 5002, and 5003 are visible in all directions except the rear 5071, and the cylinder outlets 5031, 5032, and 5033 are visible on the rear 5071. 【0110】 The propeller in Figure 21 has a hollow 5051 formed along the central axis of rotation of the spiral, and is structured to accommodate a shaft for transmitting external rotational force. 【0111】 Figure 22 shows the external shape of the 3P3F propeller from Figure 21 together with the cylinder formed inside. 【0112】 Figures 22B, 22D, 22F, and 22H show the empty space, or cylinder, formed inside Figures 22A, 22C, 22E, and 22G, respectively, in three dimensions, corresponding to the front view, top view, bottom view, and rear view of the cylinder. The three cylinder inlets 5102, 5103, and 5014 formed in the left propeller are the same as the three cylinder inlets 5102, 5103, and 5014 formed in the cylinder, respectively. 【0113】 Figure 23 shows a magnified view of the 3P3F propeller and its internal cylinder from Figure 22. 【0114】 In Figure 23A, each fin 5200 rotated approximately 220 degrees, while in Figure 23B, each internal cylinder 5210 rotated 360 degrees. In this way, by utilizing the correlation between fin rotation speed and cylinder rotation speed, the fluid flow into the cylinders can be adjusted, and the internal rotational force, internal pressure, thrust, etc. of the propeller can be adjusted to optimize the angular velocity from the external rotational force. 【0115】 Figure 24 shows a 3P6F propeller for one rotation, and the arrangement of each figure is the same as in Figure 21. 【0116】 Figure 25 shows the side view of the 3P6F propeller and the cylinder inside it. 【0117】 In Figure 25A, each fin 5400 rotates approximately 166 degrees, while in Figure 25B, each internal cylinder 5410 rotates 360 degrees, with the three-phase cylinder rotation speed being greater than the fin rotation speed. Furthermore, the ratio of the outlet section 5411 to the total length is higher compared to the cylinder in Figure 23. Not only is there a correlation between fin rotation speed and cylinder rotation speed, but the flow of fluid into the cylinder can be adjusted using the ratio derived from the length of the cylinder outlet section, influencing the propeller's internal rotational force, internal pressure, thrust, and other parameters. 【0118】 Figure 26 shows a 5P5F propeller for one rotation, and the arrangement of each figure is the same as in Figure 24. 【0119】 Figure 27 shows the side view of the 5P6F propeller and the cylinder inside it. 【0120】 In Figure 27A, each fin 5600 rotates approximately 440 degrees, while in Figure 27B, each internal cylinder 5610 rotates 360 degrees, and the rotational speed of the 5-phase cylinders is less than the rotational speed of the fins. 【0121】 Figure 28 shows a finless, hollow, single-rotation three-phase propeller. Figure 28A shows the three-phase cylinders 6710, 6711, and 6712 that make up the body of the three-phase propeller, and Figure 28B shows a single-rotation 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 variable-deformability spiral cylinder will be described using Figures 29 to 33. 【0123】 Previously, when discussing propellers using a variable-deformation spiral cylinder, we assumed that rotational motion was applied to the cylinder's central axis from the outside. Here, however, we assume that instead of rotational motion, a water or airflow flows in from the nozzle inlet. In particular, we assume that the pressure of the incoming water and airflow (i.e., water pressure and atmospheric pressure) is considerable. Depending on the type of cylinder, the nozzle will also be called an N-phase variable-deformation spiral nozzle (N-phase mVHC Nozzle). 【0124】 Figure 29 shows a variable spiral nozzle with three-phase deformation per rotation. 【0125】 Figure 29A is a front view, Figure 29B is a right side view, Figure 29C is a rear view, and Figures 29D and 29E are equiaxial projections viewed from different directions. 【0126】 The nozzle is divided into a cylindrical section 7010 and a cylinder section 7000, with the cylindrical section 7010 connected to the inlet sides 7012, 7013, and 7014 of the three-phase variable deformation cylinder. When the fluid 7002 flowing in from the outside is transmitted to the cylinder 7004 via 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 aforementioned variable spiral cylinder. 【0128】 Figure 30A is an external view of Figure 29E, and Figure 30B shows the cylinder formed inside it in three dimensions. 【0129】 In Figure 30A, the section between cylinder 7010 and cylinder 7000 is formed from the same material that constitutes the nozzle, while in Figure 30B, the internal space 70010 of the cylinder and the individual cylinder 7004 form an empty space within that material. 【0130】 On the other hand, the outer wall of the cylinder on the back surface 7101 of the nozzle is relatively thick, which is to prevent the cylinder outlet from being pushed out due to excessive pressure. 【0131】 Figures 31 and 32 show a variable spiral nozzle with five phases of deformation per rotation. 【0132】 The arrangement of the figures in Figure 31 is the same as in Figure 29, and the arrangement of the figures in Figure 32 is the same as in Figure 30. 【0133】 Figures 33A and 33B show equiaxial projections of a three-phase nozzle without a cylindrical section, viewed from different directions. The empty space inside the three-phase nozzle is formed by the three-phase cylinder. 【0134】 Figures 34 to 39 show various application examples using the variable spiral cylinder, propeller, and nozzle. 【0135】 First, Figure 34 is an example diagram showing the application of the 3P3F propeller 5000 from Figure 22 to a container ship 8000. 【0136】 Figure 35 is an example diagram showing the application of the 3P3F propeller 5000 from Figure 21 to a submarine 8100. 【0137】 Figure 36 is an illustrative diagram showing the application of the one-rotation three-phase propeller from Figure 28 to the drone 8200. The 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】 Figure 37 is an example diagram showing the application of a 3-phase cylinder per rotation to a jet engine 8300. The central axis of the 3-phase cylinder is connected to the central axis of the jet engine, and it rotates like a jet engine. When the airflow 8310 that flows into the jet engine ignites and explodes inside the engine 8320 and is ejected out of the jet engine outlet, part or all of the ejected airflow flows into the 3-phase cylinder 8330, generating additional thrust and jet force. 【0139】 Figure 38 is an illustrative diagram showing the application of a 1-rotation variable spiral three-phase nozzle 8401, which has a cylindrical section and a cylinder section, to a hydroelectric power generation Palton wheel 8400. Water flowing into the nozzle 8401 via pipe 8402 is ejected from the nozzle 8401 outlet, impacting the bucket 8403 of the Palton wheel 8400 and transmitting power. 【0140】 Figure 39 shows an example of a 1-rotation variable spiral three-phase nozzle without a cylindrical section applied to a jet engine 8500. Here, unlike in Figure 38, the three-phase nozzle is fixed in a non-rotating configuration, rather than rotating with the central axis. When the airflow 8510 flowing into the jet engine ignites and explodes inside the engine 8520 and is ejected out of the jet engine outlet, part or all of the ejected airflow flows into the three-phase cylinder 8530, generating additional thrust and jet force. 【0141】 Up to this point, we have explained variable deformation spirals and variable deformation spiral cylinders using them, utilizing various examples. 【0142】 The variable-velocity spiral cylinder (mVHC) of the present invention has the following features. 【0143】 (1) A cylinder is a hollow tube connecting an "inlet" and an "outlet," and the part excluding the inlet and outlet is sealed from the outside. Therefore, when a rotational force is applied, the force generated by the rotation is converted into linear motion while the water or airflow flowing into the outlet cannot escape, and when pressure is applied, the force increased by the rotational force generated inside the cylinder is converted into linear motion. 【0144】 (2) A variable deformation spiral is formed on the cylinder center side. 【0145】 (3) The cylinder has a tapered cylindrical shape from the cylinder inlet to the cylinder outlet, with the cross-sectional area on the inlet side being larger than the cross-sectional area on the cylinder outlet side. 【0146】 (4) One or more identical cylinders are formed to be arranged in a plurality with a predetermined phase difference around the central axis. 【0147】 (5) A fluid, i.e., a stream of water, a stream of water, or a stream of air, can enter the cylinder through the inlet and exit through the outlet of the cylinder. 【0148】 (6) The cylinder inlet is formed at an angle that maximizes the flow of fluid. 【0149】 (7) The cylinder becomes parallel to the cylinder's central axis as it approaches the tip, and the cylinder outlet is formed at an angle parallel to the cylinder's central axis so that the fluid flows out. 【0150】 (9) An external force acts on the variable spiral cylinder, generating a fluid flow at the cylinder inlet. This force may be the rotational motion of the cylinder or the pressure applied to the fluid. When a force is applied that rotates the cylinder with respect to its rotational axis, the rotational force of the cylinder causes fluid to flow into the cylinder inlet. The pressure applied to the fluid in the direction of the cylinder inlet includes the water pressure or atmospheric pressure acting at the cylinder inlet. 【0151】 (10) When fluid flows into the cylinder inlet, the incoming fluid passes through the spiral cylinder interior, generating an internal rotational force. This narrows the inner diameter of the cylinder, increasing the pressure on the fluid. As a result, compressed fluid is ejected at the cylinder outlet, generating thrust in the cylinder. The goal is to maintain the internal rotational force completely without any loss of water or airflow within the sealed cylinder, and to obtain thrust and ejection force 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 variable spiral cylinder (mVHC) is the correlation of thrust arising from the difference between the number of cylinders N and the number of fins F. By adjusting each number (N, F), the most ideal thrust can be extracted from the external rotational force. 【0153】 (12) The second feature of the propeller is the correlation of thrust resulting from the difference (i.e., phase difference) between the rotational speed (or phase) of the cylinder and the rotational speed (or phase) of the fin. That is, by making the phase of the fin smaller or larger when the phase of the cylinder per unit length is set to 1, the most ideal thrust can be extracted from the external rotational force by utilizing the phase difference between the cylinder and the fin. 【0154】 (13) A variable spiral cylinder is defined as a 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 the pitches, (iv) the ratio of the inlet to outlet area of ​​the cylinder, (v) and the length of the linear outlet section. 【0155】 (14) The height and width of the variable spiral cylinder are defined as the radius at the starting point and the radius at the ending point of the two-dimensional spiral, and the set of projection points and projection lines. 【0156】 (15) Variable spiral cylinders can be divided into those for water flow and those for air flow. 【0157】 (16) By determining whether the force driving the cylinder is rotational force or pressure, and adjusting the ratios of (i), (ii), (iii), (iv), and (v) above, the optimal thrust or jet force can be obtained. 【0158】 (17) It can be applied to a variety of applications in various industrial fields where thrust is required. Typical examples of applicable applications are propellers and nozzles. 【0159】 To date, this specification has described the invention with reference to the embodiments shown in the drawings so that a person with ordinary skill in the art to which the invention pertains can easily understand and reproduce it. However, these are merely illustrative examples, and a person with ordinary skill in the art will understand that various modifications and equivalent other embodiments of the invention are possible from these embodiments. Therefore, the true scope of technical protection of the invention should be determined solely by the appended claims.
