[0008] Hereinafter, embodiments will be described. In the embodiments, a case where a propulsion device 2 is applied to a spacecraft 1 navigating in outer space will be described as an example. Examples of the spacecraft 1 include artificial satellites, planetary probes, and the like. FIG. 1 is a diagram for explaining the propulsion device 2. In FIG. 1, the upper side in the figure corresponds to the front side in the traveling direction, and the lower side in the figure corresponds to the rear side in the traveling direction. FIG. 2 is an enlarged view of the main part of the propulsion device 2. FIG. 3 is a diagram for explaining the interaction between the magnetic body 30 and the magnetic body 40. (a) in FIG. 3 is a diagram for explaining the case where a repulsive force acts on the magnetic body 30 and the magnetic body 40. (b) in FIG. 3 is a diagram for explaining the case where an attractive force acts on the magnetic body 30 and the magnetic body 40. In FIGS. 3(a) and 3(b), in order to make the magnetic poles of the magnetic bodies 30 and 40 easy to understand, the coils 31 and 41 are omitted. Also, cross-hatchings with different pitches are provided in the regions indicating the N pole and the S pole.
[0009] As shown in FIG. 1, the spacecraft 1 navigating in the outer space SP includes a propulsion device 2 that generates propulsion, a control unit 5 that controls the driving of the propulsion device 2, and a battery 6. The propulsion device 2, the control unit 5, and the battery 6 are housed in a housing 11.
[0010] A power generation unit 12 is provided on the outer periphery of the housing 11. The power generation unit 12 can be, for example, a known solar panel or the like. The electric power generated by the power generation unit 12 is charged into the battery 6 via the cable Ha. The electric power of the battery 6 is supplied to the control unit 5 via the cable Hb. The electric power supplied to the control unit 5 is supplied to the propulsion device 2 via the cable Hc.
[0011] As shown in FIG. 2, the housing 11 has a case member 111 and a lid member 112 joined in the front-rear direction. The case member 111 has a recess 115 that depresses forward from the rear end 111a. The opening of the recess 115 is blocked by the lid member 112.
[0012] The thrust generating device 2 is housed in the space R enclosed by the recess 115 and the cover member 112. The thrust generating device 2 has a first magnetic field generating unit 3 and a second magnetic field generating unit 4, whose magnetic fields interact with each other. The first magnetic field generating unit 3 and the second magnetic field generating unit 4 are spaced apart in space R, along a straight line Lm that runs in the front-rear direction.
[0013] The first magnetic field generating unit 3 includes a magnetic body 30 (first magnetic body) and a coil 31 (first coil) surrounding the magnetic body 30. The magnetic body 30 is fixed to the case member 111 of the housing 11 with bolts (not shown) via a bracket Bk. Therefore, the magnetic body 30 is fixed to the housing 11 in an immovable manner.
[0014] The magnetic material 30 can be, for example, a rod-shaped iron core. The magnetic material 30 is oriented along a straight line La that is perpendicular to the straight line Lm. The bracket Bk is fixed to one end 30a and the other end 30b of the magnetic material 30 in the direction of the straight line La with bolts (not shown).
[0015] The coil 31 is arranged to surround the magnetic material 30 along the circumferential direction around the straight line La. The coils 31 are arranged with phase shifts in the circumferential direction around the straight line La, and are arranged in a helical shape where the position in the straight line La direction differs as you move from one end 30a to the other end 30b of the magnetic material 30.
[0016] The coil 31 has one end 311 on the magnetic material 30 side 30a that is electrically connected to the terminal 51 of the control unit 5 via the wiring Hc1 of the cable Hc. The other end 312 of the coil 31 on the magnetic material 30 side 30b that is electrically connected to the terminal 52 of the control unit 5 via the wiring Hc2 of the cable Hc.
[0017] When an electric current is passed through coil 31, magnetic field lines (magnetic fields) are formed in the magnetic material 30 surrounded by coil 31, oriented along the straight line La direction (right-hand rule). As a result, the magnetic material 30 generates a north pole and a south pole, or a south pole and a north pole, at one end 30a and the other end 30b.
[0018] In this embodiment, the control unit 5 periodically switches the direction of current supplied from terminals 51 and 52 to coil 31, thereby periodically switching the direction of magnetic field lines (N pole and S pole) formed on the magnetic material 30. For example, when current is passed through the coil 31 from end 311 to end 312, the magnetic material 30 becomes a region 30S where one end 30a is the south pole and the other end 30b is the north pole (see Figure 3(a)). On the other hand, when current is passed through the coil 31 from end 312 to end 311, the magnetic material 30 becomes a region 30N where one end 30a is an N pole and a region 30S where the other end 30b is an S pole (see Figure 3(b)).
[0019] The second magnetic field generating unit 4 includes a magnetic body 40 (second magnetic body) and a coil 41 (second coil) surrounding the magnetic body 40. The magnetic body 40 is fixed to the lid member 112 of the housing 11 with bolts (not shown) via a bracket Bk. Therefore, the magnetic body 40 is fixed to the housing 11 in an immovable manner.
[0020] The magnetic material 40 can be made of the same material as the magnetic material 30 described above (for example, a rod-shaped iron core). The magnetic material 40 is positioned along a straight line Lb that is perpendicular to the straight line Lm. The straight line Lb is parallel to the straight line La. The bracket Bk is fixed to one end 40a and the other end 40b of the magnetic material 40 in the direction of the straight line Lb with bolts (not shown).
[0021] The coil 41 is arranged to surround the magnetic material 40 along the circumferential direction around the straight line Lb. The coils 41 are arranged with phase shifts in the circumferential direction around the linear Lb, and are arranged in a helical shape where the position in the linear Lb direction differs as you move from one end 40a to the other end 40b of the magnetic material 40.
[0022] The coil 41 has one end 411 on the magnetic material 40 side 40a that is electrically connected to the terminal 53 of the control unit 5 via the wiring Hc3 of the cable Hc. The other end 412 of the coil 41 on the magnetic material 40 side 40b is electrically connected to the terminal 54 of the control unit 5 via the wiring Hc4 of the cable Hc.
[0023] When an electric current is passed through the coil 41, magnetic field lines (magnetic fields) are formed in the magnetic material 40 surrounded by the coil 41, oriented along the straight line Lb direction (right-hand rule). As a result, the magnetic material 40 generates a north pole and a south pole, or a south pole and a north pole, at one end 40a and the other end 40b.
[0024] In this embodiment, the control unit 5 periodically switches the direction of current supplied from terminals 53 and 54 to coil 41, thereby periodically switching the direction of magnetic field lines (N pole and S pole) formed on the magnetic material 40. For example, when current is passed through the coil 41 from end 411 to end 412, the magnetic material 40 becomes a region 40S where one end 40a is the south pole and the other end 40b is the north pole (see Figure 3(a)).
[0025] On the other hand, although not shown in the diagram, when current is passed through the coil 41 from end 412 to end 411, the magnetic material 40 becomes a region 40N where one end 40a is an N pole, and a region 40S where the other end 40b is an S pole.
[0026] As shown in Figures 3(a) and 3(b), the magnetic material 30 of the first magnetic field generating unit 3 and the magnetic material 40 of the second magnetic field generating unit 4 are provided with a distance L in the linear direction. As shown in Figure 3(a), when magnetic materials 30 and 40 have the same magnetic poles facing each other in the linear Lm direction (region 30N and region 40N poles facing each other, and region 30S and region 40S poles facing each other), a repulsive force Fr acts on them, which is a force that moves them apart.
[0027] On the other hand, as shown in Figure 3(b), when magnetic materials 30 and 40 have opposite magnetic poles (region 30N and region 40S, and region 30S and region 40N) facing each other in the linear Lm direction, an attractive force Fa acts on them, which is a force that moves them closer together.
[0028] Here, the inventors of this case have found, through diligent study, that the repulsive force Fr and attractive force Fa acting on the magnetic materials 30 and 40 can be used as a propulsive force if the following conditions are met. (a) In magnetic materials 30 and 40, the N pole and S pole are switched with the same period T. (b) In magnetic materials 30 and 40, the timing of when north poles face each other (regions 30N and 40N) or south poles face each other (regions 30S and 40S) is shifted in phase by 1 / 4 period. (c) The distance L between magnetic material 30 and magnetic material 40 shall satisfy the following equation (1).
number
[0029] [Forward thrust 1] Figure 4 illustrates the propagation of a magnetic field. Figure 4(a) illustrates the magnetic field propagating from magnetic material 40 to magnetic material 30. Figure 4(b) illustrates the change in the direction of the magnetic field at one end 30a, 40a of magnetic materials 30, 40. In Figure 4(b), the horizontal axis represents time, and the vertical axis represents the direction of the magnetic field. The upper part of the vertical axis corresponds to the north pole, and the lower part corresponds to the south pole.
[0030] As shown in Figures 4(a) and 4(b), the magnetic field direction of magnetic materials 30 and 40 changes in conjunction with the switching of magnetic poles. In this case, the change in the direction of the magnetic field in magnetic materials 30 and 40 is represented by waveforms W1 and W2, in which the north pole and south pole alternate with a constant period T.
[0031] As shown in Figure 4(b), in this embodiment, the control unit 5 (see Figure 2) is controlled to shift the phase by 1 / 4 period at which the north poles of the magnetic materials 30 and 40 face each other (regions 30N and 40N), or the south poles face each other (regions 30S and 40S). Specifically, the phase is shifted so that the period T on the magnetic material 30 side precedes the period T on the magnetic material 40 side by 1 / 4 of a period.
[0032] Here, the magnetic field in region 40N, which is the north pole side of the magnetic material 40, propagates through space R at the speed of light c towards the magnetic material 30 (see the white arrow in Figure 4(a)). Furthermore, the period T (sec) can be calculated from the frequencies f (Hz) of waveforms W1 and W2 using the following equation (2).
number
[0033] For example, if the frequency f of waveforms W1 and W2 is 3GHz (3 × 10⁻¹⁰ 9 When set to Hz, the distance L between magnetic materials 30 and 40 is given by equation (1) above and the propagation speed of the magnetic field (speed of light c ≈ 3 × 10) at n=0. 10 From [cm / sec], it is calculated as follows (Equation (3)).
number
[0034] Also, for example, if the frequency f of waveforms W1 and W2 is 0.75 GHz (0.75 × 10⁻¹⁰ 9 When set to Hz, the distance L between magnetic materials 30 and 40 is calculated as follows from equation (1) above when n=0 (equation (4)).
number
[0035] In equation (1) above, for example, when n=0, the interval L is (1 / 4) × T × c, where T × c corresponds to the wavelength. Therefore, when n=0, the interval L corresponds to 1 / 4 of the length of one wavelength. Consequently, the magnetic fields acting on the magnetic material 30 and the magnetic material 40 are delayed by the time it takes for the magnetic field to travel through the interval L of 1 / 4 wavelength (i.e., 1 / 4 of a period) after the magnetic field is emitted. For example, as calculated using equation (3) above, when the frequency f is 3 GHz and the distance L between magnetic materials 30 and 40 is 2.5 cm, as shown in Figure 4(b), at time t1, after 1 / 4 of a period has elapsed, one end 30a of magnetic material 30 is a north pole. At time t1, the north pole magnetic field emitted from region 40N of magnetic material 40 at time t0 reaches region 30N of magnetic material 30 (see dotted arrow a in the figure). As a result, a repulsive force Fr (see the thick arrow in Figure 4(a)) acts on the region 30N of the magnetic material 30, which occurs when two N poles face each other.
[0036] Although not shown in the diagram, at time t1, the other end 30b of the magnetic material 30 is a south pole. At time t1, the region 30S of the magnetic material 30 is acted upon by a south pole magnetic field emitted from the region 40S of the magnetic material 40 at time t0. As a result, a repulsive force Fr, which occurs when two south poles face each other, acts on region 30S of the magnetic material 30.
[0037] Furthermore, as shown in Figure 4(b), at time t3, after 3 / 4 of a period has elapsed, one end 30a of the magnetic material 30 is a south pole. At time t3, the south pole magnetic field emitted from region 40S of the magnetic material 40 at time t2, after 2 / 4 of a period has elapsed, reaches region 30S of the magnetic material 30 (see dotted arrow b in the figure). As a result, a repulsive force Fr (see the thick arrow in Figure 4(a)) acts on the region 30S of the magnetic material 30, which occurs when two south poles face each other.
[0038] Although not shown in the diagram, at time t3, the other end 30b of the magnetic material 30 is a north pole. At time t3, the region 30N of the magnetic material 30 is acted upon by the north pole magnetic field emitted from the region 40N of the magnetic material 40 at time t2. As a result, a repulsive force Fr, which occurs when two N poles face each other, acts on region 30N of the magnetic material 30.
[0039] Therefore, at times t1 and t3, a repulsive force Fr acts on the magnetic material 30, pushing it away from the magnetic material 40 in the linear Lm direction (towards the front). Here, at times t2 and t4, the magnetic material 30 is in a state where no magnetic field is generated. Therefore, by repeatedly switching the magnetic poles, a repulsive force Fr intermittently acts on the magnetic material 30. When n=1, the waveforms W1 and W2 of magnetic materials 30 and 40 are shifted by one period, so the effect on magnetic material 30 is the same as when n=0. The same applies when n≧2.
[0040] [Forward thrust 2] Figure 5 illustrates the propagation of a magnetic field. Figure 5(a) illustrates the magnetic field propagating from magnetic material 30 to magnetic material 40. Figure 5(b) illustrates the change in the direction of the magnetic field at one end 30a and 40a of magnetic materials 30 and 40.
[0041] As shown in Figure 5(b), at time t2, one end 40a of the magnetic material 40 is a south pole. At time t2, the north pole magnetic field emitted from region 30N of the magnetic material 30 at time t1 reaches region 40S of the magnetic material 40 (see dotted arrow a in the figure). As a result, an attractive force Fa (see the thick arrow in Figure 5(a)) acts on the region 40S of the magnetic material 40, which occurs when the south pole and north pole are facing each other.
[0042] Although not shown in the diagram, at time t2, the other end 40b of the magnetic material 40 is a north pole. At time t2, the south pole magnetic field emitted from the region 30S of the magnetic material 30 at time t1 acts on the region 40N of the magnetic material 40. As a result, an attractive force Fa, which occurs when the south pole and north pole are facing each other, acts on region 40N of the magnetic material 40.
[0043] Furthermore, as shown in Figure 5(b), at time t4, after one period has elapsed, one end 40a of the magnetic material 40 is a north pole. At time t4, the south pole magnetic field emitted from region 30S of the magnetic material 30 at time t3 reaches region 40N of the magnetic material 40 (see dotted arrow b in the figure). As a result, an attractive force Fa (see the thick arrow in Figure 5(a)) acts on the region 40N of the magnetic material 40, which occurs when the south pole and north pole are facing each other.
[0044] Although not shown in the diagram, at time t4, the other end 40b of the magnetic material 40 is a south pole. At time t4, the region 40S of the magnetic material 40 is acted upon by the north pole magnetic field emitted from the region 30N of the magnetic material 30 at time t3. As a result, an attractive force Fa, which occurs when the south pole and north pole are facing each other, acts on region 40S of the magnetic material 40.
[0045] Therefore, at times t2 and t4, an attractive force Fa acts on the magnetic material 40, pulling it toward the magnetic material 30 side (front side) in the linear Lm direction. Here, at times t1 and t3, the magnetic material 40 is in a state where no magnetic field is generated. Therefore, by repeatedly switching the magnetic poles, an attractive force Fa acts intermittently on the magnetic material 40.
[0046] In the thrust generator 2, the repulsive force Fr acting on the magnetic material 30 (see Figure 4) and the attractive force Fa acting on the magnetic material 40 (see Figure 5) appear alternately between times t1 and t4. This allows the directions of the forces acting on the magnetic materials 30 and 40 to be aligned.
[0047] As a result, the thrust generator 2 can generate a forward force four times during one cycle due to the repulsive force Fr (see Figure 4) acting on the magnetic material 30 and the attractive force Fa (see Figure 5) acting on the magnetic material 40. As shown in Figure 2, in the thrust generator 2, the first magnetic field generating unit 3 and the second magnetic field generating unit 4 are fixed to the housing 11 via a bracket Bk. Therefore, the thrust generator 2 moves forward together with the housing 11. This allows the spacecraft 1 to move forward (in the direction of arrow a in Figure 1).
[0048] Thus, by setting the interval L between the magnetic materials 30 and 40 based on equation (1) above, and by setting the period T on the magnetic material 30 side to be 1 / 4 period ahead of the period T on the magnetic material 40 side, the spacecraft 1 can move forward with the thrust generated by the thrust generator 2.
[0049] [Rearward thrust 1] Figure 6 illustrates the propagation of a magnetic field. Figure 6(a) illustrates the magnetic field propagating from magnetic material 40 to magnetic material 30. Figure 6(b) illustrates the change in the direction of the magnetic field at one end 30a, 40a of magnetic materials 30, 40. In the following explanation, the frequency f is assumed to be 3 GHz, and the distance L between magnetic materials 30 and 40 is assumed to be 2.5 cm, as in the cases shown in Figures 4 and 5.
[0050] In the example shown in Figure 6(b), the phase is shifted so that the period T on the magnetic material 30 side lags behind the period T on the magnetic material 40 side by 1 / 4 of a period. In this case, at time t1, after 1 / 4 of a period has elapsed, one end 30a of the magnetic material 30 is a south pole. At time t1, the north pole magnetic field emitted from region 40N of the magnetic material 40 at time t0 reaches region 30S of the magnetic material 30 (see dotted arrow a in the figure). As a result, an attractive force Fa (see the thick arrow in Figure 6(a)) acts on the region 30S of the magnetic material 30, which occurs when the south pole and north pole are facing each other.
[0051] Although not shown in the diagram, at time t1, the other end 30b of the magnetic material 30 is the north pole. At time t1, the south pole magnetic field emitted from the region 40S of the magnetic material 40 at time t0 acts on the region 30N of the magnetic material 30. As a result, an attractive force Fa, which occurs when the south pole and north pole are facing each other, acts on region 30N of the magnetic material 30.
[0052] Furthermore, as shown in Figure 6(b), at time t3, after 3 / 4 of a period has elapsed, one end 30a of the magnetic material 30 is a north pole. At time t3, the south pole magnetic field emitted from region 40S of the magnetic material 40 at time t2, after 2 / 4 of a period has elapsed, reaches region 30N of the magnetic material 30 (see dotted arrow b in the figure). As a result, an attractive force Fa (see the thick arrow in Figure 6(a)) acts on the region 30N of the magnetic material 30, which occurs when the south pole and north pole are facing each other.
[0053] Although not shown in the diagram, at time t3, the other end 30b of the magnetic material 30 is a south pole. At time t3, the region 30S of the magnetic material 30 is acted upon by the north pole magnetic field emitted from the region 40N of the magnetic material 40 at time t2. As a result, an attractive force Fa, which occurs when the south pole and north pole are facing each other, acts on the region 30S of the magnetic material 30.
[0054] Therefore, an attractive force Fa acts on the magnetic material 30, pulling it toward the magnetic material 40 in the direction of the straight line Lm (towards the rear). Here, at times t2 and t4, the magnetic material 30 is in a state where no magnetic field is generated. Therefore, by repeatedly switching the magnetic poles, an attractive force Fa intermittently acts on the magnetic material 30.
[0055] [Rearward thrust 2] Figure 7 illustrates the propagation of a magnetic field. Figure 7(a) illustrates the magnetic field propagating from magnetic material 30 to magnetic material 40. Figure 7(b) illustrates the change in the direction of the magnetic field at one end 30a and 40a of magnetic materials 30 and 40.
[0056] As shown in Figure 7(b), at time t2, one end 40a of the magnetic material 40 is a south pole. At time t2, the south pole magnetic field emitted from region 30S of the magnetic material 30 at time t1 reaches region 40S of the magnetic material 40 (see dotted arrow a in the figure). As a result, a repulsive force Fr (see the thick arrow in Figure 7(a)) acts on the region 40S of the magnetic material 40, which occurs when two south poles face each other.
[0057] Although not shown in the diagram, at time t2, the other end 40b of the magnetic material 40 is a north pole. At time t2, the region 40N of the magnetic material 40 is acted upon by the north pole magnetic field emitted from the region 30N of the magnetic material 30 at time t1. As a result, a repulsive force Fr, which occurs when two north poles face each other, acts on region 40N of the magnetic material 40.
[0058] Furthermore, as shown in Figure 7(b), at time t4, after one period has elapsed, one end 40a of the magnetic material 40 is a north pole. At time t4, the north pole magnetic field emitted from region 30N of the magnetic material 30 at time t3 reaches region 40N of the magnetic material 40 (see dotted arrow b in the figure). As a result, a repulsive force Fr (see the thick arrow in Figure 7(a)) acts on region 40N of the magnetic material 40, which occurs when two N poles face each other.
[0059] Although not shown in the diagram, at time t4, the other end 40b of the magnetic material 40 is a south pole. At time t4, the region 40S of the magnetic material 40 is acted upon by the south pole magnetic field emitted from the region 30S of the magnetic material 30 at time t3. As a result, a repulsive force Fr, which occurs when two south poles face each other, acts on region 40S of the magnetic material 40.
[0060] Therefore, a repulsive force Fr acts on the magnetic material 40, pushing it away from the magnetic material 30 in the linear Lm direction (towards the rear). Here, at times t1 and t3, the magnetic material 40 is in a state where no magnetic field is generated. Therefore, by repeatedly switching the magnetic poles, a repulsive force Fr intermittently acts on the magnetic material 40.
[0061] In the thrust generation device 2, the attractive force Fa acting on the magnetic material 30 (see Figure 6) and the repulsive force Fr acting on the magnetic material 40 (see Figure 7) appear alternately between times t1 and t4. This allows the directions of the forces acting on the magnetic materials 30 and 40 to be aligned.
[0062] As a result, the thrust generator 2 can generate a force directed towards the rear four times during one cycle due to the attractive force Fa (see Figure 6) acting on the magnetic material 30 and the repulsive force Fr (see Figure 7) acting on the magnetic material 40. Here, as shown in Figure 2, in the thrust generator 2, the first magnetic field generating unit 3 and the second magnetic field generating unit 4 are fixed to the housing 11 via bracket Bk. Therefore, the thrust generator 2 moves backward together with the housing 11. This allows the spacecraft 1 to move backward (in the direction of arrow b in Figure 1).
[0063] Thus, by setting the distance L between the magnetic materials 30 and 40 based on equation (1) above, and by setting the period T on the magnetic material 30 side to lag behind the period T on the magnetic material 40 side by 1 / 4 of a period, the spacecraft 1 can move backward with the thrust generated by the thrust generator 2. The control unit 5 can control whether to make the period T on the magnetic material 30 side precede or lag behind the period T on the magnetic material 40 side by 1 / 4 period.
[0064] Although not shown in the diagram, the thrust generating device 2 may also be equipped with an adjustment mechanism to adjust the interval L in accordance with the frequency f of the magnetic materials 30 and 40. For example, in order to reduce the power consumption of battery 6 (see Figure 1), it is possible to change the frequency f from 3 GHz to 0.75 GHz, as shown in equations (3) and (4) above. In this case, the adjustment mechanism widens the distance L between the magnetic materials 30 and 40 from 2.5 cm to 10 cm. This allows the frequency f to be changed according to the remaining charge of the battery 6, thereby controlling power consumption.
[0065] As described above, the thrust generating device 2 according to this embodiment has the following configuration. (1) The thrust generating device 2 is A magnetic material 30 (first magnetic material) and a magnetic material 40 (second magnetic material) are arranged opposite each other with a gap L between them, A first magnetic field generating unit 3 generates a magnetic field in the magnetic material 30, A second magnetic field generating unit 4 generates a magnetic field in the magnetic material 40, The system includes a control unit 5 that repeatedly reverses the direction of the magnetic field generated in the magnetic material 30 and the magnetic material 40 at the same period. The timing at which the north pole region 30N of magnetic material 30 and the north pole region 40N of magnetic material 40, or the south pole region 30S of magnetic material 30 and the south pole region 40S of magnetic material 40, face each other is shifted by a quarter period of phase. If we let T be the period, c be the propagation speed of the magnetic field, and n be a natural number (including 0), The distance L between magnetic material 30 and magnetic material 40 is L = {(1 / 4) + n} × T × c The interval is set to satisfy the following conditions.
[0066] With this configuration, the forces (repulsive force Fr, attractive force Fa) acting on the magnetic materials 30 and 40 alternate. This allows the direction of the forces acting on the magnetic materials 30 and 40 to be aligned, thereby generating a thrust force that moves in one direction without the use of propellants or the like.
[0067] (2) The first magnetic field generating unit 3 has a coil 31 (first coil) that generates a magnetic field in the magnetic material 30 when an electric current is applied. The second magnetic field generating unit 4 has a coil 41 (second coil) that generates a magnetic field in the magnetic material 40 when an electric current is applied. The control unit 5 switches the direction of current flow between coil 31 and coil 41, repeatedly reversing the direction of the magnetic fields of magnetic material 30 and magnetic material 40 with the same period T.
[0068] With this configuration, the direction of the forces acting on the magnetic materials 30 and 40 can be aligned by controlling the direction of current flow in the coils 31 and 41.
[0069] (3) The period T on the magnetic material 30 side is 1 / 4 period ahead in phase of the period T on the magnetic material 40 side.
[0070] In this configuration, a repulsive force Fr (see Figure 4) acts on the magnetic material 30 in the direction away from the magnetic material 40, and an attractive force Fa (see Figure 5) acts on the magnetic material 40 in the direction towards the magnetic material 30. As a result, the thrust generating device 2 can generate a force directed from the magnetic material 40 side toward the magnetic material 30 side (forward side).
[0071] (4) The period T on the magnetic material 30 side is 1 / 4 period behind the period T on the magnetic material 40 side in terms of phase.
[0072] In this configuration, an attractive force Fa (see Figure 6) acts on the magnetic material 30 in the direction of approaching the magnetic material 40, and a repulsive force Fr (see Figure 7) acts on the magnetic material 40 in the direction of moving away from the magnetic material 30. As a result, the thrust generating device 2 can generate a force directed from the magnetic material 30 side towards the magnetic material 40 side (rear side).
[0073] (Modifications 1 and 2) In the thrust generating device 2 according to the above embodiment, an example was given in which the rod-shaped magnetic bodies 30 and 40 are arranged in directions along the straight lines La and Lb, respectively, which are perpendicular to the straight line Lm. However, the shape of the magnetic bodies 30 and 40 is not limited to this embodiment. For example, U-shaped magnetic bodies 30A and 40A may be used.
[0074] Figure 8(a) is a diagram illustrating the thrust generating device 2A according to Modification Example 1. Figure 8(b) is a diagram illustrating the thrust generating device 2B according to Modification Example 2. In the following description, components similar to those in the embodiment will be denoted by the same reference numerals, and detailed explanations will be omitted.
[0075] As shown in Figure 8(a), the thrust generating device 2A according to the modified example 1 has a first magnetic field generating unit 3A and a second magnetic field generating unit 4A in which magnetic fields interact with each other.
[0076] The magnetic material 30A of the first magnetic field generating section 3A has a roughly U-shape, with the region intersecting the straight line Lm curved forward. The magnetic material 30A can be, for example, an iron core. One end 30a and the other end 30b of the magnetic material 30A are flat surfaces perpendicular to the straight line Lm.
[0077] Coil 31 surrounds the region where the straight lines Lm intersect in the magnetic material 30A. When current is passed through coil 31, an N pole and a S pole, or an S pole and an N pole, are generated at one end 30a and the other end 30b of the magnetic material 30A. In this case, magnetic field lines are formed along the straight line Lm direction at one end 30a and the other end 30b of the magnetic material 30A.
[0078] The magnetic material 40A of the second magnetic field generating section 4A has a roughly U-shape, with the region intersecting the straight line Lm curved to the rear. The magnetic material 40A can be, for example, an iron core. One end 40a and the other end 40b of the magnetic material 40A are flat surfaces perpendicular to the straight line Lm.
[0079] Coil 41 surrounds the region where the straight lines Lm intersect in the magnetic material 40A. When current is passed through coil 41, an N pole and a S pole, or an S pole and an N pole, are generated at one end 40a and the other end 40b of the magnetic material 40A. In this case, magnetic field lines are formed along the straight line Lm direction at one end 40a and the other end 40b of the magnetic material 40A.
[0080] Magnetic materials 30A and 40A are arranged in a symmetrical positional relationship with respect to a straight line Lc that is perpendicular to the straight line Lm. One end 30a of magnetic material 30A and one end 40a of magnetic material 40A, and the other end 30b of magnetic material 30A and the other end 40b of magnetic material 40A are facing each other with a gap L in the direction of the straight line Lm.
[0081] When current is supplied to coils 31 and 41, a repulsive force Fr or an attractive force Fa is generated between one end 30a of magnetic material 30A and one end 40a of magnetic material 40A, and between the other end 30b of magnetic material 30A and the other end 40b of magnetic material 40A, respectively.
[0082] Therefore, similar to the embodiment, by controlling the control unit 5 (see Figure 2) to shift the phase of the timing when the north poles or south poles of the magnetic materials 30A and 40A face each other by 1 / 4 period, the thrust generating device 2A can generate a thrust force directed forward or backward.
[0083] Furthermore, as shown in Figure 8(b), the thrust generating device 2B according to the modified example 2 has a first magnetic field generating unit 3B and a second magnetic field generating unit 4B in which magnetic fields interact with each other.
[0084] The magnetic material 30B of the first magnetic field generating unit 3B can be, for example, a rod-shaped iron core. The magnetic material 30B is provided in a direction along the straight line Lm. The magnetic material 30B is embedded in the case member 111A, and one end 30a in the straight line Lm direction is exposed to space R. The one end 30a of the magnetic material 30B is a flat surface perpendicular to the straight line Lm.
[0085] The coil 31 is embedded within the case member 111A of the housing 11A and is also provided to surround the magnetic material 30B along the circumferential direction around the straight line Lm. When current is passed through coil 31, an N pole and a S pole, or an S pole and an N pole, are generated at one end 30a and the other end 30b of the magnetic material 30B. In this case, magnetic field lines are formed along the straight line Lm direction at one end 30a and the other end 30b of the magnetic material 30B.
[0086] The magnetic material 40B of the second magnetic field generating unit 4B can be, for example, a rod-shaped iron core. The magnetic material 40B is provided in a direction along the straight line Lm. The magnetic material 40B is embedded in the lid member 112A, and one end 40a in the straight line Lm direction is exposed to space R. The one end 40a of the magnetic material 40B is a flat surface perpendicular to the straight line Lm.
[0087] The coil 41 is embedded within the lid member 112A of the housing 11A and is also provided to surround the magnetic material 40B along the circumferential direction around the straight line Lm. When current is passed through coil 41, an N pole and a S pole, or an S pole and an N pole, are generated at one end 40a and the other end 40b of the magnetic material 40B. In this case, magnetic field lines are formed along the straight line Lm direction at one end 40a and the other end 40b of the magnetic material 40B.
[0088] Magnetic material 30B and magnetic material 40B are arranged concentrically on a straight line Lm. One end 30a of magnetic material 30B and one end 40a of magnetic material 40B face each other with a gap L in the direction of the straight line Lm.
[0089] When current is supplied to coils 31B and 41B respectively, a repulsive force Fr or an attractive force Fa is generated between one end 30a of magnetic material 30B and one end 40a of magnetic material 40B.
[0090] Therefore, similar to the embodiment, by controlling the control unit 5 (see Figure 2) to shift the phase of the timing when the north poles or south poles of the magnetic materials 30B and 40B face each other by 1 / 4 period, the thrust generating device 2B can generate a thrust force directed forward or backward.
[0091] (Variation 3) In the above-described embodiment, an example was given in which coils 31 and 41 are provided around the magnetic materials 30 and 40 to give the magnetic materials 30 and 40 magnetic poles (N pole and S pole). However, the shape of the magnetic materials 30 and 40 is not limited to this embodiment. For example, it is also possible to use a configuration in which current is directly passed through without using coils 31 and 41.
[0092] Figure 9 is a diagram illustrating the thrust generating device 2C according to modified example 3. Figure 10 illustrates the interaction between wire 7 and wire 8. Figure 10(a) illustrates the case where an attractive force acts between wire 7 and wire 8. Figure 10(b) illustrates the case where a repulsive force acts between wire 7 and wire 8.
[0093] As shown in Figure 9, the thrust generating device 2C according to the modified example 3 has a first magnetic field generating unit 3C and a second magnetic field generating unit 4C in which magnetic fields interact with each other.
[0094] The first magnetic field generating unit 3C has a conductor 7 (first conductor). The conductor 7 can be a conductive metal rod. The conductor 7 is oriented along a straight line Ld that is perpendicular to a straight line Lm.
[0095] The conductor 7 is provided crossing space R in the direction of the straight line Ld. One side 71 and the other side 72 of the conductor 7, which are separated by the straight line Lm, are inserted into insertion holes 111b and 111c of the case member 111B of the housing 11B, respectively. As a result, the conductor 7 is provided in the housing 11B in an immovable manner.
[0096] The conductor 7 is electrically connected to the terminals 51 and 52 of the control unit 5 via the wiring Hc1 and Hc2 of the cable Hc, on one side 71 and the other side 72. When an electric current I7 is passed through the conductor 7, a circular magnetic field (magnetic field) is formed around the conductor 7, centered on the straight line Ld (right-hand rule).
[0097] For example, when a current I7 is passed from one side 71 to the other side 72 (leftward arrow in Figure 10(a)), a magnetic field H7 is formed along the counterclockwise direction CCW as viewed from the other side 72. Although not shown in the diagram, when a current I7 is passed from the other side 72 to the one side 71, a magnetic field H7 is formed along the clockwise direction CW as viewed from the other side 72.
[0098] In the thrust generating device 2C according to the modified example 3, the control unit 5 periodically switches the direction of current I7 supplied from terminals 51 and 52 to the conductor 7, thereby periodically switching the direction of the magnetic field H7 formed around the conductor 7.
[0099] The second magnetic field generating unit 4C has a conductor 8 (second conductor). The conductor 8 can be a conductive metal rod. The conductor 8 is oriented along a straight line Le that is parallel to the straight line Ld. The straight line Le is located behind the straight line Ld.
[0100] The conductor 8 is provided crossing space R in the direction of the straight line Le. The conductor 8 is inserted into insertion holes 111d and 111e of the case member 111B of the housing 11B on one side 81 and the other side 82 of the straight line Lm. As a result, the conductor 8 is provided in the housing 11B in an immovable manner.
[0101] The conductor 8 is electrically connected to the terminals 53 and 54 of the control unit 5 via the wiring Hc3 and Hc4 of the cable Hc, on one side 81 and the other side 82. When an electric current I8 is passed through the conductor 8, a circular magnetic field (magnetic field) is formed around the conductor 8, centered on the straight line Le (right-hand rule).
[0102] For example, when a current I8 is passed from one side 81 to the other side 82 (leftward arrow in Figure 10(a)), a magnetic field H8 is formed along the counterclockwise direction CCW as viewed from the other side 82. Furthermore, when current I8 is passed from the other side 82 towards the one side 81 (rightward arrow in Figure 10(b)), a magnetic field H8 is formed along the clockwise direction CW as viewed from the other side 82.
[0103] In the thrust generating device 2C according to modified example 3, the control unit 5 periodically switches the direction of current I8 supplied from terminals 53 and 54 to the conductor 8, thereby periodically switching the direction of the magnetic field H8 formed around the conductor 8.
[0104] As shown in Figures 10(a) and (b), conductors 7 and 8 are provided with a gap L in the straight line Lm direction. As shown in Figure 10(a), when the currents I7 and I8 flowing through conductors 7 and 8 are in the same direction, magnetic fields H7 and H8 are formed around conductors 7 and 8, respectively, in a counterclockwise direction (CCW) when viewed from the other side 72 and 82 (right-hand rule). In this case, according to Fleming's left-hand rule, a gravitational force Fa acts on wires 7 and 8, moving them toward each other (Case 1).
[0105] On the other hand, as shown in Figure 10(b), when the currents I7 and I8 passing through conductors 7 and 8 are in opposite directions, a magnetic field H7 is formed around conductor 7 in a counterclockwise direction (CCW) as viewed from the other side 72, and a magnetic field H8 is formed around conductor 8 in a clockwise direction (CW) as viewed from the other side 82. In this case, according to Fleming's left-hand rule, a repulsive force Fr acts on conductors 7 and 8, moving them apart from each other (Case 2).
[0106] [Rearward thrust 1] Figure 11 illustrates the propagation of a magnetic field. Figure 11(a) illustrates the magnetic field propagating from wire 8 to wire 7. Figure 11(b) illustrates the change in the direction of the magnetic field around wires 7 and 8. In Figure 11(b), the horizontal axis represents time and the vertical axis represents the direction of the magnetic field. The upper part of the vertical axis corresponds to the case where the magnetic fields H7 and H8 are aligned in the counterclockwise direction (CCW) as viewed from the other side (72 and 82), while the lower part corresponds to the case where they are aligned in the clockwise direction (CW).
[0107] As shown in Figures 11(a) and (b), the direction of the magnetic fields H7 and H8 in conductors 7 and 8 changes in conjunction with the switching of the current flow direction. In this case, the change in the direction of the magnetic fields H7 and H8 in conductors 7 and 8 is represented by waveforms W3 and W4, which alternate between clockwise (CW) and counterclockwise (CCW) directions with a constant period T.
[0108] As shown in Figure 11(b), the thrust generating device 2C according to the modified example 3 controls the direction of currents I7 and I8 by the control unit 5 (see Figure 2), shifting the phase of the timing at which the directions of magnetic fields H7 and H8 (clockwise CW, counterclockwise CCW) align by 1 / 4 period. Specifically, the phase is shifted so that the period T on the conductor 7 side precedes the period T on the conductor 8 side by 1 / 4 of a period.
[0109] For example, as calculated using equation (3) above, if the frequency f is 3 GHz and the distance L between conductors 7 and 8 is 2.5 cm, then, as shown in Figure 11(b), at time t1, after 1 / 4 of a period has elapsed, a magnetic field 7ccw is formed around conductor 7 in a direction along the counterclockwise direction CCW. At time t1, the counterclockwise magnetic field 8ccw emitted from conductor 8 at time t0 reaches conductor 7 (see dotted arrow a in the figure). As a result, an attractive force Fa (see the thick arrow in Figure 11(a)) acts on the conductor 7, which occurs when a magnetic field is formed in the same direction (counterclockwise direction CCW) (corresponding to Case 1 above).
[0110] Furthermore, as shown in Figure 11(b), at time t3, after 3 / 4 of a period has elapsed, a magnetic field 7cw is formed around the conductor 7 in a direction along the clockwise direction CW. At time t3, the magnetic field 8cw emitted from conductor 8 at time t2, after 2 / 4 of a period has elapsed, reaches conductor 7 (see dotted arrow b in the figure). As a result, the attractive force Fa (see the thick arrow in Figure 11(a)) that occurs when a magnetic field in the same direction (clockwise CW) is formed acts on the conductor 7 (corresponding to Case 1 above).
[0111] Therefore, an attractive force Fa acts on the conductor 7, pulling it toward the conductor 8 in the direction of the straight line Lm (towards the rear). Here, at times t2 and t4, no magnetic field H7 is formed around the conductor 7. Therefore, by repeatedly switching the direction of current flow, an attractive force Fa intermittently acts on the conductor 7. When n=1, the waveforms W3 and W4 of conductors 7 and 8 are shifted by one cycle, so the effect on conductor 7 is the same as when n=0. The same applies when n≧2.
[0112] [Rearward thrust 2] Figure 12 illustrates the propagation of a magnetic field. Figure 12(a) illustrates the magnetic field propagating from wire 7 to wire 8. Figure 12(b) illustrates the change in the direction of the magnetic field around wires 7 and 8.
[0113] As shown in Figure 12(b), at time t2, a magnetic field 8cw is formed around the conductor 8 in a direction along the clockwise direction CW. At time t2, the magnetic field 7ccw, which is emitted from the conductor 7 at time t1 in a counterclockwise direction CCW, reaches the conductor 8 (see dotted arrow a in the figure). As a result, a repulsive force Fr (see the thick arrow in Figure 12(a)) acts on the conductor 8, which occurs when magnetic fields are formed in opposite directions (clockwise CW and counterclockwise CCW) (corresponding to Case 2 above).
[0114] Furthermore, as shown in Figure 12(b), at time t4, after one period has elapsed, a magnetic field 8ccw is formed around the conductor 8 in a direction along the counterclockwise direction (CCW). At time t4, the magnetic field 7cw, which is clockwise (CW) and was emitted from conductor 7 at time t3, reaches conductor 8 (see dotted arrow b in the figure). As a result, a repulsive force Fr (see the thick arrow in Figure 12(a)) acts on the conductor 8, which occurs when magnetic fields are formed in opposite directions (clockwise CW and counterclockwise CCW) (corresponding to Case 2 above).
[0115] Therefore, a repulsive force Fr acts on the conductor 8, pushing it away from the conductor 7 in the straight line Lm direction (towards the rear). Here, at times t1 and t3, the conductor 8 is in a state where no magnetic field H8 is formed. Therefore, by repeatedly switching the direction of current flow, a repulsive force Fr intermittently acts on the conductor 8.
[0116] In the thrust generation device 2C, the attractive force Fa acting on the conductor 7 (see Figure 11) and the repulsive force Fr acting on the conductor 8 (see Figure 12) appear alternately between times t1 and t4. This allows the directions of the forces acting on conductors 7 and 8 to be aligned.
[0117] This allows the thrust generator 2C to generate a rearward force four times during one cycle. Therefore, the thrust generator 2C moves backward along with the housing 11B (see Figure 9). This causes the spacecraft 1 to move backward (in the direction of arrow b in Figure 1).
[0118] Thus, by setting the distance L between wires 7 and 8 based on equation (1) above, and by making the period T on the wire 7 side precede the period T on the wire 8 side by 1 / 4 of a period, a thrust force can be generated in the reverse direction.
[0119] [Forward thrust 1] Figure 13 illustrates the propagation of a magnetic field. Figure 13(a) illustrates the magnetic field propagating from wire 8 to wire 7. Figure 13(b) illustrates the change in the direction of the magnetic field around wires 7 and 8. In the following explanation, the frequency f is assumed to be 3 GHz, and the distance L between conductors 7 and 8 is assumed to be 2.5 cm, as in the cases shown in Figures 11 and 12.
[0120] In the example shown in Figure 13(b), the phase is shifted so that the period T on the conductor 7 side lags behind the period T on the conductor 8 side by 1 / 4 of a period. In this case, at time t1, after 1 / 4 of a period has elapsed, a magnetic field 7cw is formed around the conductor 7 in a direction aligned with the clockwise direction CW. At time t1, the counterclockwise magnetic field 8ccw emitted from conductor 8 at time t0 reaches conductor 7 (see dotted arrow a in the figure). As a result, a repulsive force Fr (see the thick arrow in Figure 13(a)) acts on the conductor 7, which occurs when magnetic fields are formed in opposite directions (clockwise CW and counterclockwise CCW) (corresponding to Case 2 above).
[0121] Furthermore, as shown in Figure 13(b), at time t3, after 3 / 4 of a period has elapsed, a magnetic field 7ccw is formed around the conductor 7 in a counterclockwise direction (CCW). At time t3, the clockwise magnetic field 8cw emitted from conductor 8 at time t2, after 2 / 4 of a period has elapsed, reaches conductor 7 (see dotted arrow b in the figure). As a result, a repulsive force Fr (see the thick arrow in Figure 13(a)) acts on the conductor 7, which occurs when magnetic fields are formed in opposite directions (clockwise CW and counterclockwise CCW) (corresponding to Case 2 above).
[0122] Therefore, a repulsive force Fr acts on the conductor 7, pushing it away from the conductor 8 in the straight line Lm direction (towards the front). Here, at times t2 and t4, no magnetic field H7 is formed around the conductor 7. Therefore, by repeatedly switching the direction of current flow, a repulsive force Fr intermittently acts on the conductor 7.
[0123] [Forward thrust 2] Figure 14 illustrates the propagation of a magnetic field. Figure 14(a) illustrates the magnetic field propagating from wire 7 to wire 8. Figure 14(b) illustrates the change in the direction of the magnetic field around wires 7 and 8.
[0124] As shown in Figure 14(b), at time t2, a magnetic field 8cw is formed around the conductor 8 in a direction along the clockwise direction CW. At time t2, the magnetic field 7cw, which was emitted from conductor 7 at time t1 and is in the clockwise direction CW, reaches conductor 8 (see dotted arrow a in the figure). As a result, the attractive force Fa (see the thick arrow in Figure 14(a)) that occurs when a magnetic field in the same direction (clockwise CW) is formed acts on the conductor 8 (corresponding to Case 1 above).
[0125] Furthermore, as shown in Figure 14(b), at time t4, after one period has elapsed, a magnetic field 8ccw is formed around the conductor 8 in a direction along the counterclockwise direction (CCW). At time t4, the magnetic field 7ccw, which was emitted from conductor 7 at time t3 in a counterclockwise direction (CCW), reaches conductor 8 (see dotted arrow b in the figure). As a result, the attractive force Fa (see the thick arrow in Figure 14(a)) that occurs when a magnetic field in the same direction (clockwise CW) is formed acts on the conductor 8 (corresponding to Case 1 above).
[0126] Therefore, an attractive force Fa acts on the conductor 8, pulling it towards the conductor 7 in the direction of the straight line Lm (towards the front). Here, at times t1 and t3, the conductor 8 is in a state where no magnetic field H8 is formed. Therefore, by repeatedly switching the direction of current flow, an attractive force Fa intermittently acts on the conductor 8.
[0127] In the thrust generation device 2C, the repulsive force Fr acting on the conductor 7 (see Figure 13) and the attractive force Fa acting on the conductor 8 (see Figure 14) appear alternately between times t1 and t4. This allows the directions of the forces acting on conductors 7 and 8 to be aligned.
[0128] As a result, the thrust generator 2C can generate a forward force four times during one cycle. Therefore, the thrust generator 2C moves forward along with the housing 11B (see Figure 9). This causes the spacecraft 1 to move forward (in the direction of arrow a in Figure 1).
[0129] In this way, the thrust generator 2C can generate both forward and backward forces by repeatedly switching the direction of current flow. Therefore, the spacecraft 1 equipped with the thrust generator 2C can move forward and backward.
[0130] As described above, the thrust generating device 2C according to modified example 3 has the following configuration. (5) The thrust generating device 2C is Conductors 7 (first conductor) and 8 (second conductor) are arranged parallel to each other with a gap L between them, The system includes a control unit 5 that switches the direction of current flow between conductors 7 and 8, thereby repeatedly reversing the direction of the magnetic fields H7 and H8 around conductors 7 and 8 at the same period. The timing at which the direction of the magnetic field H7 around conductor 7 and the direction of the magnetic field H8 around conductor 8 align is shifted by a 1 / 4 period phase. If we let T be the period, c be the propagation speed of magnetic fields H7 and H8, and n be a natural number (including 0), The distance L between conductor 7 and conductor 8 is L = {(1 / 4) + n} × T × c The interval is set to satisfy the following conditions.
[0131] With this configuration, the forces acting on the conductors 7 and 8 (repulsive force Fr, attractive force Fa) appear alternately. This allows the direction of the forces acting on the conductors 7 and 8 to be aligned, making it possible to generate a thrust force that moves in one direction without using propellants or the like.
[0132] (6) The period T on the conductor 7 side is 1 / 4 period ahead in phase of the period T on the conductor 8 side.
[0133] In this configuration, an attractive force Fa (see Figure 11) acts on conductor 7 in the direction of moving toward conductor 8, and a repulsive force Fr (see Figure 12) acts on conductor 8 in the direction of moving toward conductor 7. As a result, the thrust generating device 2C can generate a force directed from the conductor 7 side towards the conductor 8 side (rear side).
[0134] (7) The period T on the conductor 7 side is 1 / 4 of a period behind the period T on the conductor 8 side in terms of phase.
[0135] In this configuration, a repulsive force Fr (see Figure 13) acts on conductor 7 in the direction away from conductor 8, and an attractive force Fa (see Figure 14) acts on conductor 8 in the direction towards conductor 7. As a result, the thrust generating device 2C can generate a force directed from the conductor 8 side towards the conductor 7 side (front side).
