Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in this case, thrust due to centrifugal force in a direction different from the target thrust direction is also generated simultaneously. Therefore, there is a desire to reduce the thrust in the unintended direction. Also, theoretically, the thrust obtained by increasing the rotational speed increases, but in reality, as the rotational speed increases, centrifugal forces are generated in various directions, increasing the vibration of the entire device. As a result, there is a problem that the thrust in the target direction decays. An object of the present invention is to solve these problems and provide a thrust generation method capable of efficiently generating only thrust in a certain direction.

Embodiments for Carrying Out the Invention

[0011] Embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are merely examples, and there is no intention to exclude various modifications and applications of technologies not explicitly described below. That is, the present invention can be implemented with various modifications (such as combining each embodiment) as long as it exhibits its effects. Also, in the description of the following drawings, the same or similar parts are denoted by the same or similar reference numerals. The drawings are schematic and do not necessarily match the actual dimensions, ratios, etc. There may be parts where the dimensional relationships and ratios are different between the drawings. Also, in order to avoid making the following description unnecessarily redundant and to facilitate the understanding of those skilled in the art, detailed descriptions of well-known matters and duplicate descriptions of substantially the same configurations may be omitted.

[0012] <First Embodiment> FIGS. 1 to 6 are schematic explanatory diagrams showing the mechanism of the thrust generating device 100 according to the first embodiment. In the thrust generating method in this embodiment, in the thrust generating device 100 that generates thrust by rotating the gear 21 as the first rotating body provided with the weight 24 and the gear 22 as the second rotating body provided with the weight 26, while the weight 24 of the gear 21 rotates counterclockwise from the 6 o'clock direction to the 3 o'clock direction with respect to the rotation center of the gear 21, The weight 26 of gear 22 rotates clockwise from the 6 o'clock position to the 9 o'clock position relative to the rotation center of gear 22, The configuration is essential to generate thrust in the 12 o'clock direction relative to the rotation centers of gear 21 and gear 22.

[0013] Figure 2 is a schematic diagram showing the mechanism of the thrust generator 100 as viewed from the direction of gear 21 in Figure 1 (from the right direction in Figure 1), and Figure 5 is a schematic diagram showing the mechanism of the thrust generator 100 as viewed from the direction of gear 21 in Figure 4 (from the right direction in Figure 4).

[0014] The thrust generating device 100 includes a gear 21 with a weight 24 attached via a shaft 23a from a rotating shaft 23 which is the center of rotation, a gear 22 with a weight 26 attached via a shaft 25a from a rotating shaft 25 which is the center of rotation, and a rotating body 14 as a driving link that rotates by receiving driving force from a motor (not shown) which is the drive source. Furthermore, it includes a reciprocating rack gear 16 that engages with gears formed on gears 21 and gear 22 and reciprocates along a guide groove 18a provided on the plate-shaped body 18, and a conversion arm 15 that connects the rotating body 14 and the reciprocating rack gear 16.

[0015] The rotating shafts 23 and 25 are pivotally supported on the plate-like body 18. Figures 1 to 6 show examples in which the shaft 23a and weight 24, and the shaft 25a and weight 26 are arranged on the front side of the plate-like body 18, but the configuration is not limited to this. Either one or both of the shaft 23a and weight 24, or the shaft 25a and weight 26, may be arranged on the back side of the plate-like body 18. Furthermore, it is preferable that the total weight of shaft 23a and weight 24 is the same as the total weight of shaft 25a and weight 26.

[0016] The rotating body 14 and gears 21 and 22 are rotatably mounted on the plate-shaped body 18. Rotating shaft holes (not shown) are provided at both ends of the rotating body 14 and the conversion arm 15, and at one end of the reciprocating rack gear 16. A first rotating shaft pin 17a is inserted through the rotating shaft hole formed in the rotating body 14 and the rotating shaft hole formed at one end of the conversion arm 15, so that the rotating body 14 and one end of the conversion arm 15 are rotatably connected around the first rotating shaft pin 17a as an axis.

[0017] Furthermore, the second rotational shaft pin 17b is inserted through a rotational shaft hole formed in the reciprocating rack gear 16 and a rotational shaft hole formed in the other end of the conversion arm 15, so that the reciprocating rack gear 16 and the other end of the conversion arm 15 are rotatably connected around the second rotational shaft pin 17b as an axis. In addition, the second rotational shaft pin 17b is inserted through a guide groove 18a provided in the plate-like body 18.

[0018] The moving shaft pin 17c is inserted through a shaft hole provided at the other end of the reciprocating rack gear 16 into the guide groove 18a, so that the reciprocating rack gear 16 always reciprocates along the guide groove 18a. Gears 21 and 22 are fitted to each of the multiple gears formed in the direction of movement of the reciprocating rack gear 16 (left and right in the example shown in the figure), and gears 21 and 22 rotate in accordance with the reciprocating motion of the reciprocating rack gear 16.

[0019] The thrust generating device 100 utilizes a slider-crank mechanism that converts the rotational motion of a rotating body 14 into the reciprocating linear motion of a reciprocating rack gear 16. In a slider-crank mechanism, the rotational motion of a driving link is converted into reciprocating motion along the direction in which the slider slides. In the thrust generating device 100, the rotating body 14 is configured as the driving link of the slider-crank mechanism, and the reciprocating rack gear 16 is configured as the slider of the slider-crank mechanism.

[0020] Specifically, when the rotating body 14 rotates around the rotation axis 14a supported on the plate-shaped body 18, receiving driving force from the motor (not shown), which is the drive source, one end of the conversion arm 15 also rotates around the rotation axis 14a via the first rotation axis pin 17a. As a result of the rotation of one end of the conversion arm 15, the reciprocating rack gear 16 moves along the guide groove 18a via the second rotation axis pin 17b inserted through the other end of the conversion arm 15.

[0021] Furthermore, in this embodiment, the reciprocating linear motion of the reciprocating rack gear 16 is utilized to provide gears 21 and 22 that are fitted to gears formed in the direction of movement of the reciprocating rack gear 16, and weights 24 and 26 are attached to the gears 21 and 22, respectively. Gear 21 rotates around the rotation axis 23, and the weight 24 attached to gear 21 also rotates around the rotation axis 23. Gear 22 rotates around the rotation axis 25, and the weight 26 attached to gear 22 also rotates around the rotation axis 25.

[0022] Starting from the state shown in Figure 1, as the rotating body 14 rotates, one end of the conversion arm 15, which is connected via the first rotation axis pin 17a, also rotates around the rotation axis 14a. When the rotating body 14 rotates 180 degrees from the state shown in Figure 1, one end of the conversion arm 15 also rotates 180 degrees around the rotation axis 14a (Figure 1 → Figure 3 → Figure 4).

[0023] At this time, the reciprocating rack gear 16 connected via the conversion arm 15 moves. In the example of Figure 1 → Figure 3 → Figure 4, the reciprocating rack gear 16 moves downward in the figure. As the reciprocating rack gear 16 moves, the gears 21 and 22 that are fitted to it rotate.

[0024] Specifically, gear 21 rotates counterclockwise, causing weight 24, located at the 6 o'clock position in Figure 1, to begin rotating counterclockwise towards the 3 o'clock position. Simultaneously, gear 22 rotates clockwise, causing weight 26, located at the 6 o'clock position in Figure 1, to begin rotating clockwise towards the 9 o'clock position (Figure 1 → Figure 3 → Figure 4).

[0025] Using the position of the reciprocating rack gear 16 when the rotation of the rotating body 14 is 0 degrees (Figure 1) as a reference, the amount of movement of the reciprocating rack gear 16 connected via the conversion arm 15 is maximized when the rotating body 14 rotates 180 degrees (Figures 4 and 5).

[0026] As the weight 24 of gear 21 rotates counterclockwise from the 6 o'clock direction to the 3 o'clock direction relative to the rotation center of gear 21, and at the same time as the weight 26 of gear 22 rotates clockwise from the 6 o'clock direction to the 9 o'clock direction relative to the rotation center of gear 22, a thrust in the 12 o'clock direction relative to the rotation centers of gear 21 and gear 22 can be generated.

[0027] As the rotating body 14 rotates further, one end of the conversion arm 15, which is connected via the first rotation axis pin 17a, also rotates, and the reciprocating rack gear 16, which is connected via the conversion arm 15, also moves. The reciprocating rack gear 16 moves upward in the figure. As the reciprocating rack gear 16 moves, the gears 21 and 22 that are fitted to it also rotate (Figure 4 → Figure 6 → Figure 1).

[0028] Specifically, gear 21 rotates clockwise, causing weight 24, located at the 3 o'clock position in Figure 4, to begin rotating clockwise towards the 6 o'clock position. Simultaneously, gear 22 rotates counterclockwise, causing weight 26, located at the 9 o'clock position in Figure 4, to begin rotating counterclockwise towards the 6 o'clock position.

[0029] As explained above, from the state shown in Figure 1, weights 24 and 26 rotate, and at the moment their rotation stops (Figure 4), thrust F can be efficiently generated in the tangential direction of the rotation of weights 24 and 26 (upward in the figure, at the 12 o'clock position relative to the rotation centers of gears 21 and 22).

[0030] Furthermore, the left-right component of the centrifugal force generated when weight 24 rotates and the left-right component of the centrifugal force generated when weight 26 rotates cancel each other out. A downward component remains, but it is negligible compared to the thrust F generated.

[0031] With this configuration, the thrust generating device 100 can efficiently generate thrust F in the tangential direction to the rotation of weights 24 and 26 by continuously rotating the rotating body 14.

[0032] <Second Embodiment> Figures 7 to 10 are schematic diagrams illustrating the mechanism of the thrust generating device 200 according to the second embodiment. The thrust generation method in this embodiment is a thrust generation method in a thrust generating device 200 that generates thrust by rotating a gear 41, which is a first rotating body equipped with a weight 44, and a gear 42, which is a second rotating body equipped with a weight 46. The weight 44 of gear 41 rotates counterclockwise from the 9 o'clock direction through the 6 o'clock direction to the 3 o'clock direction with respect to the rotation center of gear 41, and then rotates clockwise from the 3 o'clock direction through the 6 o'clock direction to the 9 o'clock direction, The weight 46 of gear 42 rotates clockwise from the 3 o'clock direction through the 6 o'clock direction to the 9 o'clock direction relative to the rotation center of gear 42, and then rotates counterclockwise from the 9 o'clock direction through the 6 o'clock direction to the 3 o'clock direction, The configuration is such that when the weights 44 and 46 are at the 3 o'clock and 9 o'clock positions, a thrust is generated in the 12 o'clock direction relative to the rotation center of gears 41 and 42.

[0033] The thrust generating device 100 of the first embodiment was a mechanism that rotated weights 24 and 26 by 90 degrees to obtain thrust F in the tangential direction of rotation of weights 24 and 26 at the moment their rotation stops, whereas the second embodiment is a mechanism that rotates the weights by 180 degrees to obtain thrust F in the tangential direction of rotation. Repetitive explanations of configurations similar to those of the first embodiment may be omitted.

[0034] The thrust generating device 200 includes a gear 41 with a weight 44 attached via a shaft 43a from a rotating shaft 43 which is the center of rotation, a gear 42 with a weight 46 attached via a shaft 45a from a rotating shaft 45 which is the center of rotation, a rotating body 34 as a driving link that rotates by receiving driving force from a motor (not shown) which is the drive source, a reciprocating rack gear 36 that is fitted with gears 41 and gear 42 and reciprocates along a guide groove 38a provided in a plate-shaped body 38, and a conversion arm 35 that connects the rotating body 34 and the reciprocating rack gear 36.

[0035] The rotating shafts 43 and 45 are pivotally supported on the plate-like body 38. Figures 7 to 10 show an example in which the shaft 43a and weight 44 are arranged on the front side, which is any face of the plate-like body 38, and the shaft 45a and weight 46 are arranged on the back side, which is the opposite face of the plate-like body 38. However, the configuration is not limited to this. Considering the size of each shaft and weight, they may be arranged on the same side. It is preferable that the total weight of the shaft 43a and weight 44 and the total weight of the shaft 45a and weight 46 are the same.

[0036] The rotating body 34 and gears 41 and 42 are rotatably mounted on the plate-shaped body 38. Rotating shaft holes (not shown) are provided at both ends of the rotating body 34 and the conversion arm 35, and at one end of the reciprocating rack gear 36. A first rotating shaft pin 37a is inserted through the rotating shaft hole formed in the rotating body 34 and the rotating shaft hole formed at one end of the conversion arm 35, so that the rotating body 34 and one end of the conversion arm 35 are rotatably connected around the first rotating shaft pin 37a as an axis.

[0037] Furthermore, the second rotational shaft pin 37b is inserted through a rotational shaft hole formed in the reciprocating rack gear 36 and a rotational shaft hole formed in the other end of the conversion arm 35, so that the reciprocating rack gear 36 and the other end of the conversion arm 35 are rotatably connected around the second rotational shaft pin 37b as an axis. In addition, the second rotational shaft pin 37b is inserted through a guide groove 38a provided in the plate-shaped body 38.

[0038] The moving shaft pin 37c is inserted through a shaft hole provided at the other end of the reciprocating rack gear 36 into the guide groove 38a, so that the reciprocating rack gear 36 always reciprocates along the guide groove 38a. Gears 41 and 42 are fitted to each of the multiple gears formed in the direction of movement of the reciprocating rack gear 36 (left and right in the example shown in the figure), and gears 41 and 42 rotate in accordance with the reciprocating motion of the reciprocating rack gear 36.

[0039] The thrust generating device 200 utilizes a slider-crank mechanism that converts the rotational motion of the rotating body 34 into the reciprocating linear motion of the reciprocating rack gear 36. In this embodiment, a long reciprocating rack gear 36 is used to rotate gears 41 and 42 by 180 degrees, thereby rotating weights 44 and 46 by 180 degrees.

[0040] When the rotating body 34 rotates around the rotating shaft 34a supported on the plate-shaped body 38, receiving driving force from the motor (not shown), which is the driving source, one end of the conversion arm 35 also rotates around the rotating shaft 34a via the first rotating shaft pin 37a. As a result of the rotation of one end of the conversion arm 35, the reciprocating rack gear 36 moves along the guide groove 38a via the second rotating shaft pin 37b inserted through the other end of the conversion arm 35.

[0041] As the reciprocating rack gear 36 moves, the gears 41 and 42 that engage with the reciprocating rack gear 36 rotate around the rotation axis 43 and rotation axis 45, respectively (Figure 7 → Figure 8).

[0042] From the state shown in Figure 7, as gear 41 rotates counterclockwise, weight 44 located at the 9 o'clock position rotates counterclockwise towards the 6 o'clock position. Simultaneously, as gear 42 rotates clockwise, weight 46 located at the 3 o'clock position rotates clockwise towards the 6 o'clock position (Figure 7 → Figure 8). Furthermore, as the rotating body 34 continues to rotate, weight 44 located at the 6 o'clock position in Figure 8 rotates counterclockwise towards the 3 o'clock position, and simultaneously, weight 46 located at the 6 o'clock position in Figure 8 rotates clockwise towards the 9 o'clock position (Figure 8 → Figure 9).

[0043] In this way, as the weight 44 of gear 41 rotates counterclockwise from the 9 o'clock direction through the 6 o'clock direction to the 3 o'clock direction relative to the rotation center of gear 41, and at the same time as the weight 46 of gear 42 rotates clockwise from the 3 o'clock direction through the 6 o'clock direction to the 9 o'clock direction relative to the rotation center of gear 42, a thrust in the 12 o'clock direction relative to the rotation centers of gear 41 and gear 42 can be generated when weight 44 is at the 3 o'clock position and when weight 46 is at the 9 o'clock position.

[0044] In other words, from the state shown in Figure 7, weights 44 and 46 rotate, and at the moment their rotation stops (Figure 9), thrust F can be efficiently generated in the tangential direction of the rotation of weights 44 and 46 (upward in the figure, at the 12 o'clock position relative to the rotation centers of gears 41 and 42).

[0045] As the rotating body 34 continues to rotate and the gear 41 rotates clockwise, the weight 44 rotates clockwise in the 6 o'clock direction relative to the rotation center of the gear 41. Simultaneously, as the gear 42 rotates counterclockwise, the weight 46 rotates counterclockwise in the 6 o'clock direction relative to the rotation center of the gear 42 (Figure 9 → Figure 10). Subsequently, the weight 44 rotates clockwise in the 9 o'clock direction relative to the rotation center of the gear 41, and simultaneously, the weight 46 rotates counterclockwise in the 3 o'clock direction relative to the rotation center of the gear 42 (Figure 10 → Figure 7).

[0046] In this way, as the weight 44 of gear 41 rotates clockwise from the 3 o'clock direction through the 6 o'clock direction to the 9 o'clock direction relative to the rotation center of gear 41, and at the same time as the weight 46 of gear 42 rotates counterclockwise from the 9 o'clock direction through the 6 o'clock direction to the 3 o'clock direction relative to the rotation center of gear 42, a thrust in the 12 o'clock direction relative to the rotation centers of gear 41 and gear 42 can be generated when weight 44 is at the 9 o'clock position and when weight 46 is at the 3 o'clock position.

[0047] In other words, from the state shown in Figure 9, weights 44 and 46 rotate, and at the moment their rotation stops (Figure 7), thrust F can be efficiently generated in the tangential direction of the rotation of weights 44 and 46 (upward in the figure, at the 12 o'clock position relative to the rotation centers of gears 41 and 42).

[0048] Furthermore, the left-right component of the centrifugal force generated when weight 44 rotates, and the left-right component of the centrifugal force generated when weight 46 rotates, cancel each other out. A downward component remains, but it is negligible compared to the thrust F generated.

[0049] In this way, by continuously rotating the rotating body 34, the weights 44 and 46 can be rotated as shown in Figures 7→8→9→10→7→8→9→10, ..., and the thrust F in the tangential direction of the rotation of the weights 44 and 46 (upward in the figures, at the 12 o'clock position with respect to the rotation centers of gears 41 and 42) can be efficiently generated when the weights 44 and 46 are in the state shown in Figure 7 and when they are in the state shown in Figure 9.

[0050] The configurations of the thrust generating devices 100 and 200 that realize the thrust generating method of the present invention have been described above. For both thrust generators 100 and 200, the thrust F generated increases with increasing gear rotation speed (weight rotation speed). Furthermore, the thrust F increases with weight. Additionally, the thrust F increases with a larger rotation radius of the weight. Therefore, the rotation speed, weight, and rotation radius of the weight should be adjusted while considering the weight of the thrust generators 100 and 200 themselves. Furthermore, the rotating bodies 14 and 34 only need to function as driving links for the slider-crank mechanism and do not necessarily have to be rotating gears. For example, they may be circular or rod-shaped and used as driving links.

[0051] <Variation> Figures 11 and 12 are schematic diagrams illustrating the mechanism of a modified example. These figures show an example in the thrust generating device 200 where the rod-shaped body 50 is replaced with the driving link of a slider-crank mechanism instead of the rotating body 34. The rod-shaped body 50 is rotatably mounted on the plate-shaped body 38. Rotation shaft holes (not shown) are provided at both ends of the rod-shaped body 50. A first rotation shaft pin 37a is inserted through the rotation shaft hole formed in the rod-shaped body 50 and the rotation shaft hole formed in one end of the conversion arm 35, so that the rod-shaped body 50 and one end of the conversion arm 35 are rotatably connected around the first rotation shaft pin 37a as an axis.

[0052] When the rod-shaped body 50 rotates around the rotating shaft 50a supported on the plate-shaped body 38 by the driving force from the motor (not shown), which is the driving source (Figure 11 → Figure 12), one end of the conversion arm 35 also rotates around the rotating shaft 50a via the first rotating shaft pin 37a. As a result of the rotation of one end of the conversion arm 35, the reciprocating rack gear 36 moves along the guide groove 38a via the second rotating shaft pin 37b inserted through the other end of the conversion arm 35. The rotation of the gears 41, 42 and weights 44, 46 that rotate in conjunction with the movement of the reciprocating rack gear 36 is the same as described above and will therefore be omitted.

[0053] By using the rod-shaped body 50, the thrust generating device 200 can be made lighter compared to when the rotating body 34 is used. Furthermore, the same operational configuration as described above will be observed even if the rod-shaped body 50 is provided instead of the rotating body 14 of the thrust generating device 100.

[0054] <Application Examples> The configuration of the thrust generating device 100 is shown as an example in which a weight is placed on the front side, which is an arbitrary surface, but a weight may also be placed on the back side, which is the opposite side of the arbitrary surface. Figures 13 to 16 are schematic diagrams illustrating the mechanism of a thrust generating device 300, which is an example of an application to the configuration of the thrust generating device 100, and shows weights and the like arranged not only on the front side of the plate-shaped body 18 but also on the back side.

[0055] The thrust generator 300 has a configuration in which weights and the like are placed on the rear side of the thrust generator 100. The front side has the same configuration as the thrust generator 100 (Figures 1, 3, 4, and 6), so its description and illustration are omitted.

[0056] Figure 13 shows the rear view relative to Figure 1, Figure 14 shows the rear view relative to Figures 3 and 6, and Figure 15 shows the rear view relative to Figure 4. Figure 16 is a plan view relative to the front view Figure 1 (rear view Figure 13). Specifically, it is a schematic diagram illustrating the mechanism of the thrust generator 300 as seen from direction 17c (from above) relative to the front view Figure 1 (rear view Figure 13). The rotation of the thrust generator 300 from the front is the same as that of the thrust generator 100, so the illustration and explanation of the rotation are omitted. Furthermore, explanations of other components similar to those of the thrust generator 100 may be omitted to avoid repetition.

[0057] In this application example, the thrust generation method is such that the weight 24 of the first rotating body, gear 21, and the weight 26 of the second rotating body, gear 22, of the thrust generation device 300 are located on the front side, which is any arbitrary side of the thrust generation device 300. On the rear side, which is the opposite side of the thrust generation device 300, another first weight 28 is located coaxially with the rotation axis 23 of gear 21, and another second weight 29 is located coaxially with the rotation axis 25 of gear 22. When viewed from the front, the weight 24 of gear 21 rotates clockwise from the 3 o'clock position to the 6 o'clock position. When this occurs (Figure 4 → Figure 6 → Figure 1), viewed from the rear, the other first weight 28 rotates counterclockwise from the 6 o'clock direction to the 3 o'clock direction (Figure 15 → Figure 14 → Figure 13), and when viewed from the front, the weight 26 of gear 22 rotates counterclockwise from the 9 o'clock direction to the 6 o'clock direction (Figure 4 → Figure 6 → Figure 1), the other second weight 29 rotates clockwise from the 6 o'clock direction to the 9 o'clock direction (Figure 15 → Figure 14 → Figure 13), and it is essential that this configuration generates thrust in the 12 o'clock direction with respect to the rotation center of gears 21 and 22.

[0058] In this application example, the thrust generating device 300 is provided with a weight 28 coaxially with the rotation shaft 23 of gear 21 and a weight 29 coaxially with the rotation shaft 25 of gear 22. In this application example, the rotation shafts 23 and 25 are rotatably supported through a plate-like body 18, with the weight 28 attached to the rotation shaft 23 via a shaft 23b and the weight 29 attached to the rotation shaft 25 via a shaft 25b. It is preferable that the total weight of the shaft 23b and weight 28 and the total weight of the shaft 25b and weight 29 are the same.

[0059] As described in the first embodiment, on the front side, a weight 24 is attached to the rotating shaft 23 via a shaft 23a, and a weight 26 is attached to the rotating shaft 25 via a shaft 25a. The rotating body 14, which rotates in response to the driving force from a motor (not shown) that is the drive source, and the gears 21 and 22 rotate via the conversion arm 15 and the reciprocating rack gear 16, causing the weights 24 and 26 to rotate (Figure 1 → Figure 3 → Figure 4 → Figure 6 → Figure 1 → ...).

[0060] On the rear side, the weight 28 attached to the rotation axis 23 of gear 21 rotates around the rotation axis 23, and the weight 29 attached to the rotation axis 25 of gear 22 rotates around the rotation axis 25. Starting from the state in Figure 13, as the rotating body 14 rotates, gear 21 rotates, and the weight 28 located at the 3 o'clock position rotates clockwise towards the 6 o'clock position. Simultaneously, gear 22 rotates, and the weight 29 located at the 9 o'clock position rotates counterclockwise towards the 6 o'clock position (Figure 13 → Figure 14 → Figure 15). As the rotating body 14 rotates further, gear 21 rotates, and the weight 28 located at the 6 o'clock position in Figure 15 rotates counterclockwise towards the 3 o'clock position. Simultaneously, gear 22 rotates, and the weight 29 located at the 6 o'clock position in Figure 15 rotates clockwise towards the 9 o'clock position (Figure 15 → Figure 14 → Figure 13).

[0061] From the state shown in Figure 15, weights 28 and 29 rotate, and at the moment their rotation stops (Figure 13), thrust F can be efficiently generated in the tangential direction of the rotation of weights 28 and 29 (upward in the figure, at the 12 o'clock position relative to the rotation centers of gears 21 and 22).

[0062] According to the thrust generating device 300 described above, thrust can be generated by the weights 24 and 26 on the front side at the moment the device reaches the state shown in Figure 4, and thrust can be generated by the weights 28 and 29 on the rear side at the moment the device reaches the state shown in Figure 1.

[0063] The configurations of the thrust generating devices 100, 200, and 300 described above, and their variations, merely illustrate the basic points of the thrust generating devices that realize the thrust generating method of the present invention. In other words, the technical scope of the thrust generating method according to the present invention is not limited to the scope described in each of the embodiments described above, and various changes or improvements can be made within the scope of the claims. Note that the figures in the attached drawings are schematic and not necessarily strictly accurate. In particular, the described movements and the number of teeth on the gears, the size of each gear and each rotating body, and the length of each shaft may not exactly match.

[0064] The scope of application of the present invention is not limited to the configuration described above. The present invention can be broadly applied to thrust generation methods that can generate thrust using a rotating body equipped with a weight. [Explanation of Symbols]
