Embodiments for Carrying Out the Invention

[0013] Hereinafter, the structure, control system, control device, control method, and program of the present disclosure will be described with reference to the drawings.

[0014] FIG. 1 is a diagram showing an example of a structure according to an embodiment of the present disclosure. In FIG. 1, a structure 1 and a surface effect wing craft 2 are shown. As an example, the surface effect wing craft 2 floats and moves on the sea surface using the surface effect. The structure 1 is provided in the traveling direction of the surface effect wing craft. The structure 1 is composed of at least a first intersection surface 11, a second intersection surface 12, and a main surface 13.

[0015] The first intersection surface 11 is a surface that intersects the sea surface from below the sea surface upward in the passing direction of the surface effect wing craft 2 at a first passing position 18, which is one of two positions spaced apart in the traveling direction of the plane (sea surface) where the surface effect wing craft 2 obtains the surface effect. The second intersection surface 12 is a surface that intersects the sea surface from above the sea surface downward in the passing direction of the surface effect wing craft 2 at a second passing position 19, which is the position where the surface effect wing craft 2 passes later among the two positions. The main surface 13 is a surface that connects the first intersection surface 11 and the second intersection surface 12.

[0016] In the present disclosure, the structure 1 is configured such that at least the first angle θ1 and the second angle θ2 are variable. The first angle θ1 may be defined as the angle between the vector of the traveling direction on the plane (sea surface) where the surface effect aircraft 2 obtains the surface effect and the inclination of the first intersection surface 11. The second angle θ2 may be defined as the angle between the vector in the direction opposite to the traveling direction on the plane (sea surface) where the surface effect aircraft 2 obtains the surface effect and the inclination of the second intersection surface 12.

[0017] In FIG. 1, the first intersection surface 11, the second intersection surface 12, and the main surface 13 are shown as being planar, but the first intersection surface 11, the second intersection surface 12, and the main surface 13 may have curved surfaces. For example, the first intersection surface 11, the second intersection surface 12, and the main surface 13 may be formed by connecting a plurality of planar tiles of a predetermined area, and it is assumed that adjacent tiles are connected by a connecting mechanism. An actuator for controlling the posture of each tile is connected to each of these tiles, and by adjusting the angle formed between the surface of one tile and the surface of the other adjacent tile, the position of the curved surface in the entirety of the first intersection surface 11, the second intersection surface 12, and the main surface 13, and the curvature of the curved surface may have a function that can be made variable. Each tile constituting the first intersection surface 11, the second intersection surface 12, and the main surface 13 may have a large area with a planar shape such as a square or a rectangle with each side being, for example, 5 meters or 10 meters.

[0018] The acute first angle θ1 formed by the sea surface and the first intersection surface 11 is configured to gradually increase from the first passing position 18 toward the traveling direction of the surface effect aircraft 2, and may be controlled to be a gentle curved surface that is convex downward. The acute second angle θ2 formed by the second intersection surface 12 and the sea surface is configured to gradually decrease toward the traveling direction of the surface effect aircraft 2 up to the second passing position 19, and may be controlled to be a gentle curved surface that is convex downward. The connecting portions between the first intersection surface 11 and the main surface 13, and between the second intersection surface 12 and the main surface 13 may each be controlled to be gentle continuous curved surfaces between the surfaces.

[0019] The structure described above creates a space between the main surface 13 and the sea surface. Structure 1 is formed in this space such that there is enough space between the sea surface and the main surface 13 for other moving objects (other ships, other surface effect aircraft 2, etc.) to move. Normally, structure 1 is installed hidden below the sea surface, and structure 1 may be raised from the sea surface to the surface effect aircraft 2 so that it passes over other moving objects when the surface effect aircraft 2 passes the position of structure 1, or when the direction of travel of the surface effect aircraft 2 and other moving objects intersect at the position of structure 1. The surface effect aircraft 2 may move sequentially while floating up by utilizing the surface effect of the first intersecting surface 11, main surface 13, and second intersecting surface 12 of structure 1 that has risen above the sea surface, and then float up on the sea surface again to move. This allows the surface effect aircraft 2 to move while intersecting with other moving objects.

[0020] As described above, one embodiment of the present disclosure has been explained, and according to the above process, even when the surface effect vane 2 intersects with the path of another moving body, by installing the structure 1, the surface effect vane 2 can proceed smoothly without significant deceleration even if they intersect at the same time and position.

[0021] Incidentally, if the above-mentioned structure 1 is constructed on the sea, the acute first angle θ1 formed between the sea surface and the first intersection surface 11, and the acute second angle θ2 formed between the sea surface and the second intersection surface 12 will fluctuate due to changes in sea level. Therefore, it is necessary to control the first angle θ1 and the second angle θ2 based on the time when the surface effect vane 2 passes over the structure 1.

[0022] Figure 2 shows the relationship between a control device, an actuator, and a structure according to one embodiment of the present disclosure. As described above, the angle formed by the faces of adjacent tiles among a plurality of planar tiles of a predetermined area that constitute the first intersecting surface 11, the second intersecting surface 12, and the main surface 13 is controlled by a control device 3 that controls the orientation of each tile. The control device 3 is connected to each actuator 4 by a communication line or the like. Each actuator 4 controls the angle of the faces of adjacent tiles among a plurality of planar tiles of a predetermined area that constitute the first intersecting surface 11, the second intersecting surface 12, and the main surface 13, and drives them so that the first intersecting surface 11, the second intersecting surface 12, and the main surface 13 become a plane or a curved surface. The actuator 4 may have a drive mechanism that moves the tile up and down in the normal direction, or a drive mechanism that changes the normal direction of the tile's surface in three-dimensional space. In this disclosure, the control device 3 controls at least the first acute angle θ1 formed between the sea surface and the first intersecting surface 11 near the first passing position 18, and the second acute angle θ2 formed between the second intersecting surface 12 and the sea surface.

[0023] Figure 3 is the first diagram illustrating the problems that arise during sea-level rise according to one embodiment of this disclosure. As shown in Figure 3, if the first intersection surface 11 has a gently convex curved surface in the direction of movement of the surface effect aircraft 2 with respect to the first passing position 18, the acute first angle θ1 between the first intersection surface 11 and the sea surface increases as the sea surface rises. In other words, before the sea surface rises, the first intersection surface 11 and the sea surface form a continuous, gently curved surface, but as it changes to a steeper curve, the first angle θ1 between the first intersection surface 11 and the sea surface changes to a larger angle θ1' (Figure 3). As a result, when the surface effect aircraft 2 changes from a state where it floats above the sea surface to a state where it floats above the first intersection surface 11, it may not be able to obtain the surface effect properly, raising concerns that the airframe of the surface effect aircraft 2 may collide with the structure 1.

[0024] Figure 4 is a second figure illustrating the problems that arise during sea-level rise according to one embodiment of this disclosure. As shown in Figure 4, if the second intersection surface 12 has a gently convex curved surface in the direction of movement of the surface effect aircraft 2 relative to the second passing position 19, the acute second angle θ2 between the second intersection surface 12 and the sea surface increases as the sea surface rises. In other words, before the sea surface rises, the second intersection surface 12 and the sea surface form a continuous, gently curved surface, but as it changes to a steeper curve, the second angle θ2 between the second intersection surface 12 and the sea surface changes to a larger angle θ2' (Figure 4). As a result, when the surface effect aircraft 2 changes from a state where it is floating above the second intersection surface 12 to a state where it is floating above the sea surface, it may not be able to obtain the surface effect properly, raising concerns that the airframe of the surface effect aircraft 2 may collide with the sea surface.

[0025] Therefore, the control device 3 controls the acute first angle θ1 formed between the first intersection surface 11 and the sea surface at the first passing position 18, and the acute second angle θ2 formed between the second intersection surface 12 and the sea surface at the second passing position 19. The control device 3 controls the acute angle formed between the first intersection surface 11 and the sea surface for each tile in a predetermined range in the direction of movement of the surface effect vane 2 with respect to the first passing position 18, and the acute angle formed between the second intersection surface 12 and the sea surface for each tile in a predetermined range in the direction of movement of the surface effect vane 2 with respect to the second passing position 19, so that the continuous surface between the sea surface and the first intersection surface 11, and the continuous surface between the second intersection surface 12 and the sea surface are gently curved surfaces, and so that the surface effect vane 2 can move while maintaining surface effect and floating.

[0026] Figure 5 shows the hardware configuration of a control device according to one embodiment of the present disclosure. As shown in Figure 5, the control device 3 may be a computer equipped with hardware such as a CPU (Central Processing Unit) 101, ROM (Read Only Memory) 102, RAM (Random Access Memory) 103, storage device 104, communication module 105, and input device 106.

[0027] Figure 6 is a functional block diagram of a control device according to one embodiment of the present disclosure. The CPU 101 of the control device 3 executes the control program. As a result, the control device 3 performs the functions of the information acquisition unit 31, the sea level calculation unit 32, the timing determination unit 33, the angle calculation unit 34, and the structure control unit 35. The information acquisition unit 31 acquires various types of information to be used in processing. The sea level calculation unit 32 calculates the height of the sea level. The timing determination unit 33 determines the timing for controlling the structure 1 based on the position of the surface effect vane 2. The angle calculation unit 34 calculates the angles of the controllable positions of the first intersecting surface 11, the second intersecting surface 12, and the main surface 13. The structural control unit 35 controls the angles of the first intersecting surface 11, the second intersecting surface 12, and the main surface 13 based on the angles of the first intersecting surface 11, the second intersecting surface 12, and the main surface 13.

[0028] Figure 7 is a first diagram showing the processing flow of a control device according to one embodiment of the present disclosure. Figure 8 is a first figure showing a controlled structure according to one embodiment of the present disclosure. Figure 9 is a second figure showing a controlled structure according to one embodiment of the present disclosure.

[0029] Next, the processing flow of the control device according to one embodiment of the present disclosure will be described in order. First, the information acquisition unit 31 acquires the information necessary for processing (step S101). Specifically, the information acquisition unit 31 acquires the coordinates (latitude, longitude) and speed of the target surface effect vane 2 at each time point. The information acquisition unit 31 also acquires information for calculating the sea level. For example, the information for calculating the sea level may be the high tide time and low tide time at the location of the structure 1, the current tide level, weather forecast information, etc.

[0030] The timing determination unit 33 calculates the time at which the surface effect vane 2 passes the first passing position 18 and the second passing position 19 of the structure 1 (step S102). For example, the timing determination unit 33 acquires the coordinates (latitude, longitude) and velocity of the surface effect vane 2 at each time point, and calculates the time at which the surface effect vane 2 passes the first passing position 18 and the second passing position 19 based on the coordinates and velocity of the surface effect vane 2 and the coordinates of the first passing position 18 and the second passing position 19. The coordinates (latitude, longitude) and velocity of the surface effect vane 2 at each time point may be detected by the surface effect vane 2 itself and transmitted to the control device 3, or some detection device may detect the coordinates and velocity of the surface effect vane 2 and transmit them to the control device 3.

[0031] The sea level calculation unit 32 calculates the sea level at the position of the structure 1 at the time when the surface effect vane 2 passes the first passing position 18 or the second passing position 19 (step S103). The sea level may be the rise in sea level from a reference height, or the drop in sea level from a reference height. The sea level calculation unit 32 may also calculate the sea level at each future time in advance.

[0032] The angle calculation unit 34 uses at least the sea surface height when the surface effect vane 2 passes the first passing position 18 and the second passing position 19 to calculate the first acute angle θ1 between the first intersection surface 11 and the sea surface at the time the surface effect vane 2 passes the first passing position 18, and the second acute angle θ2 between the second intersection surface 12 and the sea surface at the time the surface effect vane 2 passes the second passing position 19 (step S104).

[0033] The angle calculation unit 34 may input the calculated sea surface height into the first angle calculation formula and the second angle calculation formula, respectively, which include sea surface height as a parameter, to calculate the first angle θ1 and the second angle calculation formula. The first angle calculation formula and the second angle calculation formula may further include at least one of the following values ​​as parameters: the speed of the surface effect aircraft 2, the gravity of the surface effect aircraft 2, and the length of the surface effect aircraft 2 in the direction of travel. In this case, the information acquisition unit 31 acquires information such as the speed of the surface effect aircraft 2, the gravity of the surface effect aircraft 2, and the length of the surface effect aircraft 2 in the direction of travel. The angle calculation unit 34 may input the parameters necessary for calculation from the speed of the surface effect aircraft 2, the gravity of the surface effect aircraft 2, and the length of the surface effect aircraft 2 in the direction of travel into the first angle calculation formula and the second angle calculation formula, respectively, to calculate the first angle θ1 and the second angle calculation formula. The first angle calculation formula and the second angle calculation formula may include other parameters.

[0034] The angle calculation unit 34 outputs a first angle θ1 and a second angle θ2 to the structural control unit 35. The structural control unit 35 controls the actuator 4 so that the acute angle between the first intersection surface 11 and the sea surface at the first passing position 18 is the first angle θ1 (Figure 8) (step S105). The first angle θ1 should be an angle that allows the surface effect vane aircraft 2 to move while floating using the surface effect. The structural control unit 35 controls the actuator 4 so that the acute angle between the second intersection surface 12 and the sea surface at the second passing position 19 is the second angle θ2 (Figure 9) (step S106). The second angle θ2 should also be an angle that allows the surface effect vane aircraft 2 to move while floating using the surface effect. By controlling the cross-sectional shape of the surface of the structure 1 in the direction of travel in this way, even when the sea surface rises or falls, the surface effect vane aircraft 2 can move while floating from the sea surface to the surface of the structure 1, and when moving while floating from the surface of the structure 1 to the sea surface, collisions with the surface of the structure 1 or the sea surface can be prevented.

[0035] Furthermore, if the first intersection surface 11 and the second intersection surface 12 are formed by the connection of multiple tiles, the angle calculation unit 34 may calculate the angle of each tile within a predetermined range based on the first passing position 18 and the angle of each tile within a predetermined range based on the second passing position 19. The structure control unit 35 may then control the angles of each tile within a predetermined range based on the first passing position 18 and the second passing position 19 based on the angles of each tile calculated by the angle calculation unit 34, so that the first intersection surface 11 and the second intersection surface 12 as a whole become a smooth curved surface. In this case, the angle calculation unit 34 may use an angle calculation formula corresponding to each tile and the above-mentioned parameters to calculate the angle that each tile surface makes with the sea surface. The above-mentioned angle calculation formula may include a parameter indicating the climbing performance of the surface effect wing aircraft 2, and the angle calculation unit 34 may input the parameter indicating the climbing performance acquired by the information acquisition unit 31 into the angle calculation formula to calculate each angle, including the first angle θ1 and the second angle θ2 mentioned above.

[0036] The angle calculation unit 34 may control the angles of each tile constituting the main surface 13 based on the angles of each tile on the first intersecting surface 11 and the angles of the corner tiles on the second intersecting surface 12, so that the first intersecting surface 11, the second intersecting surface 12, and the main surface 13 as a whole form a smooth curved surface. In this case as well, the angle calculation unit 34 may calculate the angles of each tile constituting the main surface 13 using a predetermined angle calculation formula.

[0037] Figure 10 is a second diagram showing the processing flow of a control device according to one embodiment of the present disclosure. Here, the processing flow shown in Figure 7 above illustrates an example where structure 1 is pre-installed on the sea. However, structure 1 may be installed so that it is submerged in the sea when surface effect vane 2 is not passing over structure 1, and the control device 3 may raise structure 1 to the surface of the sea just before surface effect vane 2 passes over the position of structure 1 or just before surface effect vane 2 intersects with other moving objects at the position of structure 1. This raises structure 1, which is normally invisible in the sea, to the surface of the sea, allowing surface effect vane 2 to float and move on the surface of structure 1, while other moving objects can move beneath structure 1 at the same time.

[0038] In this case, the timing determination unit 33 calculates the timing of the surface effect vane 2's passage through the structure 1 and the timing of the passage of the other moving body (step S201). The calculation of the timing of the passage of the other moving body may be performed in the same manner as the calculation of the timing of the surface effect vane 2's passage described above. The timing determination unit 33 determines, for example, whether a predetermined time range based on the timing of the surface effect vane 2's passage through the structure 1 and a predetermined time range based on the timing of the other moving body's passage through the structure 1 overlap at least partially (step S202). The timing determination unit 33 may determine whether the timing of the surface effect vane 2 and the other moving body's passage through the structure 1 overlaps by other processes.

[0039] The timing determination unit 33 determines that a predetermined time range based on the timing of the surface effect vane 2 passing through the structure 1 overlaps with a predetermined time range based on the timing of other moving objects passing through the structure 1, at least partially. In this case, the timing determination unit outputs the overlapping time range to the structure control unit 35. The structure control unit 35 controls the actuator 4 to raise the structure 1 from underwater to above water a predetermined time before the overlapping time between the timing of the surface effect vane 2 passing through the structure 1 and the timing of other moving objects passing through the structure 1 (step S203). This causes the structure 1 to float on the water. After that, the control device 3 performs the processes described in steps S101 to S106 above.

[0040] The structural control unit 35 of the control device 3 may determine the width of the structure 1 centered on the direction of movement of the surface effect vane 2, and control the actuator 4 to float only that portion of the structure 1 to the surface of the sea. In this case, the structural control unit 35 may calculate the width using the wingspan of the surface effect vane 2 acquired by the information acquisition unit 31, as well as the wind direction, wind speed, and atmospheric pressure on that day, as parameters included in the width calculation formula. The structural control unit 35 controls the structure 1 to float to the surface of the sea based on the calculated width centered on the direction of movement of the surface effect vane 2.

[0041] The structural control unit 35 may control the position of the surface normal to the surface of the structure 1 so as to prevent the surface effect vane 2 from floating and moving higher than necessary relative to the surface of the structure 1, or from floating and moving closer than necessary to the surface of the structure 1. For example, the information acquisition unit 31 acquires the altitude at which the surface effect vane 2 is moving from the surface effect vane 2. Based on the acquired altitude of the surface effect vane 2 and the current position and shape of the structure 1 in space, the structural control unit 35 calculates the distance between the surface effect vane 2 and the first intersection surface 11, the distance between the surface effect vane 2 and the second intersection surface 12, and the distance between the surface effect vane 2 and the main surface 13. The structural control unit 35 may also predict the distance between the surface effect vane 2 and the first intersection surface 11, the distance between the surface effect vane 2 and the second intersection surface 12, and the distance between the surface effect vane 2 and the main surface 13 after a predetermined time.

[0042] The structural control unit 35 then uses actuators 4 to control the spatial position of each tile constituting the first intersection surface 11, the second intersection surface 12, and the main surface 13 so that the distance between the surface effect aircraft 2 and the first intersection surface 11, the distance between the surface effect aircraft 2 and the second intersection surface 12, and the distance between the surface effect aircraft 2 and the main surface 13 falls within a predetermined range. In this case as well, the structural control unit 35 may control the attitude (position and angle) of each tile so that the surface of the structure 1, composed of the first intersection surface 11, the second intersection surface 12, and the main surface 13, becomes a smooth curved surface as a whole. Through such control, the control device 3 can maintain a constant distance between the surface effect aircraft 2 and the surface of the structure 1, thereby controlling the structure 1 so that the surface effect aircraft 2 is not considered an aircraft requiring flight approval by public authorities.

[0043] Figure 11 shows another example of controlling a structure according to one embodiment of the present disclosure. The control device 3 may control the structure 1 such that, when two surface effect aircraft 2 intersect at the same time at the position of the structure 1, one lighter surface effect aircraft 2 floats above the top of the structure 1, while the other heavier surface effect aircraft 2 passes below the structure 1 while continuing to float above the sea surface. Let's call one of these two surface effect aircraft 2 "surface effect aircraft 2a" and the other "surface effect aircraft 2b". In this case, the structural control unit 35 of the control device 3 acquires the weight (or number of passengers) of surface effect aircraft 2a and the weight (or number of passengers) of surface effect aircraft 2b, which are acquired from the outside by the information acquisition unit 31. The structural control unit 35 identifies the lighter (or with fewer passengers) surface effect aircraft 2. Now, let's assume that the structural control unit 35 has identified the surface effect aircraft 2a moving from left to right on the plane of Figure 11 as the lighter (or with fewer passengers) surface effect aircraft 2.

[0044] The structural control unit 35 of the control device 3 identifies the range of the surfaces that will become the first intersection surface 11, the second intersection surface 12, and the main surface 13 of the structure 1 based on the direction of movement of the identified surface effect vane 2a. Based on the above processing, the structural control unit 35 raises the structure 1 from its submerged state to the sea surface, and calculates the first acute angle θ1 between the identified first intersection surface 11 and the sea surface, and the second acute angle θ2 between the identified first intersection surface 12 and the sea surface, and similarly controls the structure 1 using the actuator 4. In this way, the control device 3 can control the identified surface effect vane 2a, which is lighter in weight (or has fewer passengers), to float and move on the upper surface of the structure 1, and the surface effect vane 2b, which is lighter in weight (or has fewer passengers), to continue moving while floating on the sea surface beneath the structure 1.

[0045] Although the above example described a case where structure 1 is installed on the sea, structure 1 may also be installed on a lake or on land.

[0046] When structure 1 is installed in a lake, the first intersecting surface 11 is the surface that intersects the lake surface from below to above in the direction of the surface effect aircraft 2's passage at the first passing position 18, which is one of two positions on the lake surface where the surface effect aircraft 2 obtains the surface effect, spaced apart in the direction of the surface effect aircraft 2's movement. The second intersecting surface 12 is the surface that intersects the lake surface from above to below in the direction of the surface effect aircraft 2's passage at the second passing position 19, which is one of the two positions where the surface effect aircraft 2 passes later.

[0047] If the structure 1 is installed on the ground, for example, the first intersecting surface 11 is a surface that intersects the ground from bottom to top in the direction of passage of the surface effect aircraft 2 at the first passing position 18, which the surface effect aircraft 2 passes first, out of two positions on the ground on which the surface effect aircraft 2 obtains the surface effect, separated in the direction of passage of the surface effect aircraft 2. The second intersecting surface 12 is a surface that intersects the ground from top to bottom in the direction of passage of the surface effect aircraft 2 at the second passing position 19, which the surface effect aircraft 2 passes later, out of the two positions mentioned above.
