Description

Technical Field

[0001] The invention relates to an aerospace propulsion device. Background Art

[0002] At present, aerospace power mainly relies on rocket engines, followed by ion thrusters. The common point of the two is that they rely on the expulsion of matter to generate reaction force. In contrast, British physicist Roger Shoyer proposed the electromagnetic drive EmDrive theory, which uses radio frequency electromagnetic waves to generate standing waves in a closed metal cavity, forming an asymmetric electromagnetic distribution, causing radiation differences inside the cavity, thereby generating a tiny thrust. Although it has been confirmed, its maximum thrust at 2.5 kWh is only 720 mN. Because the thrust is too weak, it has no practical application at present. Summary of the invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a microwave aerospace thruster, which generates thrust through the mutual magnetic interaction between microwaves and coils, thereby avoiding the aerospace engine's dependence on ejected matter. Since the magnetic field force is much greater than the reflection force of electromagnetic waves in the metal cavity, a new solution is provided for aerospace propulsion.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a microwave generator is used to connect the waveguide, a coil is installed in the waveguide, and the microwave generator is connected in series with the coil in the waveguide through a wire. Among them, multiple coils are installed in the waveguide, and the distance between the first coil and the microwave generator antenna is L=0.25λ+0.5nλ, wherein λ is the wavelength of the microwave, n is a natural number, and the spacing between all coils after the first coil is 0.5λ. The microwave generator transmits the microwave electrical signal to the coil through a wire, and the length of the wire connecting the first coil is L+nλ, and the length of the wire connected in series between all coils after the first coil is 0.5λ+nλ. The wire length is calculated based on the microwave speed in the wire being equal to the speed of light, and the actual length should be adjusted according to the actual speed of the microwave in the wire. The shape of the waveguide is not limited to one form, and can be a straight line, a curve, and a closed ring. If it is a closed ring, the microwave generator can directly input microwaves, or introduce microwaves into the ring waveguide through a Y-type waveguide. The form of the coil in the waveguide is not limited to the traditional closed ring, but can also be an open U-shaped coil and a linear coil like a microwave antenna. During operation, the microwave generator emits microwaves into the waveguide through the antenna. When the microwaves reach the first coil, the wire also transmits the microwave electrical signal to the first coil and generates a magnetic field. Since the two have the same frequency and the arrival time difference is (L+nλ)-L=nλ, that is, the phase is always the same, an attraction with a constant direction is generated. When the magnetic field of the first coil is transmitted to the antenna of the microwave generator in the opposite direction, due to the distance, the number of waves passing through the antenna is 2L / λ=0.5+n. It can be seen that the phase difference between the waveform emitted by the microwave and the waveform returned by the first coil is π / 2, which indicates that the interaction between the antenna and the magnetic field returned by the coil is a repulsive force. In this way, the interaction force between the antenna and the first coil has the same direction, thus providing a unidirectional power for the system. The same principle applies to the coil at the back. The added coil can multiply the power. If the waveguide is annular, after the microwave enters the annular waveguide through the Y-shaped waveguide, when the annular circumference is an integer multiple of the microwave wavelength, the microwave will continue to increase in intensity in the annular waveguide until the loss is equal to the input of the microwave generator, thus reducing the power consumption of the microwave generator. In addition, the annular waveguide changes the direction of the microwave, which can also change the direction of the original interaction force.

[0005] The beneficial effect of the present invention is that the time difference of microwave propagation is used to change the direction of the reaction force, thereby solving the defect of aerospace engines relying on ejected matter and providing a new solution for aerospace development.

[0009] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0010] exist Figure 1 In the invention, a magnetron (1) is used to connect a waveguide (5), a plurality of annular coils (3) are installed in the waveguide (5), an antenna (2) is connected in series with the annular coils (3) via a wire (4), wherein the distance between the first annular coil (3) and the antenna (2) is 3.05 cm, the spacing between the annular coils (3) is 6.1 cm, the length of the wire (4) between the antenna (2) and the first annular coil (3) is 7.625 cm, the length of the wire (4) between the annular coils (3) is 9.25 cm, and the wires (4) are shielded. When in operation, the antenna (2) emits microwaves into the waveguide (5). At the same time, the antenna (2) transmits microwave electrical signals to the annular coil (3) through the wire (4). Since the speed of microwaves in the wire (4) is only C / 2, the difference between the microwave and the wire (4) signals when they reach the first annular coil (3) is 7.625 / 0.5-3.05=12.2 cm (wavelength of microwaves), that is, the phases of the two signals when they reach the first annular coil (3) are the same. Therefore, the first annular coil (3) is always affected by the gravitational force of the antenna (2), and the same is true for all subsequent annular coils (3). However, when the microwaves generated by the first annular coil (3) are transmitted to the antenna (2) in the reverse direction, the time from when the antenna (2) starts to emit microwaves to the first annular coil (3) is 2L / C. Therefore, at this time, the phase difference between the microwaves of the antenna (2) and the phase of the returned microwaves is 2L, that is, 6.1 cm, which is exactly half of the microwave wavelength of 12.2 cm. Therefore, the antenna (2) is subjected to a repulsive force. Since the force directions of the antenna (2) and the annular coil (3) are the same, the entire system is subjected to force and generates power.

[0011] exist Figure 2In the invention, a magnetron (1) is used to connect a Y-type waveguide (8), the Y-type waveguide (8) is connected to a ring waveguide (9), a linear coil (6) and a U-shaped coil (7) are connected inside the ring waveguide (9), and an antenna (2) is connected in series with the linear coil (6) via a wire (4), wherein the distance between the linear coil (6) and the antenna (2) and the wire length difference between them are set according to the difference in signal propagation speed being equal to the microwave wavelength nλ. During operation, the antenna (2) emits microwaves into the Y-shaped waveguide (8), and the Y-shaped waveguide (8) transmits the microwaves to the annular waveguide (9). Since the inner circumference of the annular waveguide (9) is an integral multiple of the microwave wavelength, the microwaves in the annular waveguide (9) are continuously enhanced until the loss thereof is equal to the microwaves emitted by the antenna (2) into the Y-shaped waveguide (8). Therefore, the actual power of the microwaves is greatly enhanced. Among them, the force applied to the linear coil (6) is similar to that of the annular coil (3), and thus will not be described in detail. The newly added U-shaped coil (7) is relatively special. This coil has an opening, and an air plate capacitor is connected at the opening. The U-shaped coil (7) There is no external wire (4), so there is no requirement for the installation distance, and dense installation is possible. The force on the U-shaped coil (7) is achieved through induced current. Under the action of the microwave alternating magnetic field, an alternating current is formed in the U-shaped coil (7), and each side thereof generates a current and a corresponding magnetic field, and interacts with the adjacent sides. Since there are only three sides, the whole is ultimately subjected to force due to unbalanced force. Since the force direction is consistent with the axial direction of the antenna (2), and the current of the antenna (2) is in the axial direction, no reaction force can be generated. At the same time, the curved annular waveguide (9) also changes the direction of the reaction force, making it impossible for the system to have an internal force balance, thus generating power.
