Description

Technical Field

[0001] This invention relates to the field of electromagnetic launch technology, and in particular to a magnetically levitated guided three-stage vacuum electromagnetic catapult waverider launch system. Background Technology

[0002] Traditional rockets rely heavily on their own fuel for launch, resulting in high energy consumption, high cost, and long preparation periods during takeoff. With technological advancements, electromagnetic catapult technology has gradually been adopted. Currently, most electromagnetic catapults use a single horizontal or vertical track. For example, common electromagnetic catapult tracks are horizontal with a small angle of elevation or a single vertical track. When multiple horizontal track segments are spliced ​​together, only a zigzag connection structure can be formed. Zigzag structures suffer from high impact, high overload, and are easily damaged. For instance, when a rocket passes through a zigzag point, the sudden change in direction causes a huge inertial force, potentially damaging the rocket structure and affecting its normal flight. In other words, existing electromagnetic catapult launches cannot achieve a smooth transition from horizontal or small angle of elevation to vertical launch.

[0003] Furthermore, for common horizontal or vertical single tracks, the launch slider generally operates in two ways after rocket launch. One method involves the launch slider being disposable, discarded after launch along with the rocket. This significantly increases launch costs and wastes resources. The other method involves the launch slider being blocked by a stop at the end of the track to prevent it from being launched. However, the massive impact of the launch slider can damage the stop, and even affect the normal operation of the electromagnetic launch track under a large impact.

[0004] Therefore, existing electromagnetic catapult tracks suffer from problems such as the inability to smoothly change direction and the inconvenience of retrieving the catapult slider. Summary of the Invention

[0005] The purpose of this application is to solve the problems of electromagnetic catapult tracks in the prior art, such as the inability to smoothly turn and the inconvenience of retrieving the catapult slider.

[0006] To solve the above-mentioned technical problems, the embodiments of this application disclose a magnetically levitated guided three-section vacuum electromagnetic catapult waverider launch system, including a launch track, a buffer return track, and a carrier launch component. The tail end of the launch track is connected to the head end of the buffer return track, and the tail end of the buffer return track is connected to the head end of the launch track. The carrier launch component can reciprocate along the launch track and the buffer return track.

[0007] The launch track includes a primary acceleration section, an arc-shaped transition section, and an acceleration launch section connected sequentially along the launch direction of the launch track. The primary acceleration section extends obliquely in the horizontal direction, the arc-shaped transition section is arc-shaped, and the acceleration launch section extends vertically.

[0008] The launch vehicle carries the target component, and the launch vehicle accelerates sequentially from the beginning of the launch track through the primary acceleration section, the arc transition section and the acceleration launch section before launching the target component in a vertical direction.

[0009] Using the above technical solution, the launch trajectory of the launch system disclosed in this application includes a primary acceleration section, an arc-shaped transition section, and an acceleration launch section. The arc-shaped transition section is designed in an arc shape, which allows for a smoother turning process for the launch vehicle. The launch vehicle and its onboard payload experience uniform force during turning, avoiding the enormous impact force and high overload caused by sudden turns. This ensures the stability of the payload's flight attitude during launch, improves launch accuracy and success rate, and solves the problem of unsmooth turning in existing technologies.

[0010] Furthermore, the tail end of the launch track is connected to the head end of the buffer landing track, and the tail end of the buffer landing track is also connected to the head end of the launch track, forming a closed-loop track system. This eliminates the need for a stop at the tail end of the launch track and avoids the problem of the launch vehicle component flying out or becoming unusable after a single launch. After completing its launch mission, the launch vehicle component decelerates and returns to the head end of the launch track due to inertia, enabling convenient and efficient recovery of the launch vehicle component. This avoids the impact of high-speed return or high-speed stopping, reduces the risks during recovery, and thus increases the service life of the launch system.

[0011] The embodiments of this application also disclose a magnetically levitated guided three-section vacuum electromagnetic catapult waverider launch system. A first arc-shaped connecting track is provided between the tail end of the launch track and the head end of the buffer return track, and a second arc-shaped connecting track is provided between the tail end of the buffer return track and the head end of the launch track. The launch track, the first arc-shaped connecting track, the buffer return track, and the second arc-shaped connecting track are connected in sequence to form a circular track.

[0012] The bottom of the circular track is also equipped with a track support. After the launch component is launched from the launch track, it passes through the first arc-shaped connecting track, the buffer return track and the second arc-shaped connecting track in sequence to return to the beginning of the launch track.

[0013] By adopting the above technical solution, the setting of the first arc-shaped connecting track and the second arc-shaped connecting track makes the transition between the launch vehicle and the buffer landing track smoother. The arc-shaped track can provide a smoother transition and avoid impact and vibration. The construction of the ring track makes the structure of the entire launch system more compact.

[0014] The embodiments of this application also disclose a magnetically levitated guided three-section vacuum electromagnetic catapult waverider launch system, which further includes a vacuum launch pipe, a launch track disposed inside the vacuum launch pipe, and the vacuum launch pipe extending in the same direction as the launch track.

[0015] The vacuum emission pipeline includes multiple vacuum pipelines that are sequentially sealed and spliced ​​along the axial direction. A vacuum bellows is also sealed between two adjacent vacuum pipelines. Multiple vacuum tube interfaces are arranged at intervals along the circumference on the outer wall of each vacuum pipeline, and each vacuum tube interface is connected to a vacuum pump.

[0016] By employing the above technical solution, the vacuum launch pipeline provides a near-vacuum launch environment for the launch track, significantly reducing space resistance and thereby improving the launch speed and efficiency of the launch vehicle and its payload. The vacuum launch pipeline utilizes multiple vacuum pipelines sealed and spliced ​​together, facilitating installation and assembly. This allows for the easy construction of longer launch pipelines to meet the needs of different launch track lengths. A vacuum bellows is sealed between adjacent vacuum pipelines. The vacuum bellows possess excellent flexibility and sealing properties, compensating for minor displacements and deformations caused by temperature changes, installation errors, or external vibrations. Furthermore, the vacuum bellows can be easily and smoothly bent at angles, allowing for the splicing of smooth, arc-shaped transition sections.

[0017] The embodiments of this application also disclose a magnetically levitated guided three-section vacuum electromagnetic catapult waverider launch system. Two sets of electromagnetic propulsion components are also arranged at intervals inside the vacuum launch pipe, on both sides of the launch track and the launch vehicle. Each set of electromagnetic propulsion components extends along the length direction of the launch track, and each set of electromagnetic propulsion components includes multiple electromagnetic drive coils arranged sequentially along the length direction.

[0018] The launch vehicle is equipped with a moving coil group on both sides facing the two sets of electromagnetic propulsion components. Each moving coil group includes multiple moving coils. When the two sets of electromagnetic propulsion components are energized, the multiple electromagnetic drive coils interact with each other and jointly drive the moving coil group and the launch vehicle to move along the launch direction of the launch track.

[0019] Using the above technical solution, two sets of electromagnetic propulsion components are spaced apart on both sides of the launch track and the launch vehicle. Each set contains multiple electromagnetic drive coils arranged sequentially along the length of the launch track. The multiple electromagnetic drive coils drive the launch vehicle to move on the track. The electromagnetic drive coils at different positions play their roles in sequence to provide continuous and stable thrust to the launch vehicle, ensuring that the launch vehicle can accelerate quickly and smoothly to the required launch speed.

[0020] The embodiments of this application also disclose a magnetically levitated guided three-section vacuum electromagnetic catapult waverider launch system, wherein the launch track is set as a magnetically levitated track, a magnetically levitated drive electromagnetic coil is arranged on the magnetically levitated track, and a magnetically levitated electromagnetic coil adapted to the magnetically levitated drive electromagnetic coil is arranged on the carrier launch component.

[0021] Using the above technical solution, the magnetic levitation drive electromagnetic coil on the magnetic levitation track interacts with the magnetic levitation electromagnetic coil on the launch vehicle, generating a stable electromagnetic force that suspends the launch vehicle at a certain distance above the launch track. This contactless levitation method eliminates the friction caused by traditional mechanical support structures, greatly reducing energy loss and allowing the launch vehicle to be rapidly accelerated to launch speed, thereby reducing the length of the launch track.

[0022] The embodiments of this application also disclose a magnetically levitated guided three-section vacuum electromagnetic catapult waverider launch system, wherein the magnetic levitation track is set as a "T"-shaped track, and the carrier launch component is provided with a "T"-shaped groove adapted to the "T"-shaped track.

[0023] The "T"-shaped track also has a groove in the middle of its width direction, which extends along the length of the magnetic levitation track, and a power supply cable is installed in the groove.

[0024] By employing the above technical solution, the "T"-shaped track and the "T"-shaped groove on the launch vehicle component work together to provide more reliable guidance for the launch vehicle component. The "T"-shaped structure can constrain it in both horizontal and vertical directions, effectively preventing the launch vehicle component from shifting left or right or swaying up and down during high-speed movement, thus improving the accuracy and stability of the launch. Furthermore, placing the power supply cable within the groove can protect the power supply cable.

[0025] The embodiments of this application also disclose a magnetically levitated guided three-stage vacuum electromagnetic catapult waverider launch system. Inside the vacuum launch pipe, a magnetically levitated electromagnetic component is also provided on one side of each set of electromagnetic propulsion components. The magnetically levitated electromagnetic component is located on the side of the electromagnetic propulsion component closer to the launch track.

[0026] The electromagnetic drive coil is set as a ring coil, and the magnetic levitation electromagnetic component includes multiple magnetic levitation coils arranged sequentially along the length of the launch track. Each magnetic levitation coil is set as an "8" shaped coil.

[0027] Using the above technical solution, the figure-eight coil has unique magnetic field distribution characteristics. When current passes through the figure-eight coil, a specific magnetic field is generated around it, which interacts with the corresponding magnetic levitation structure on the launch vehicle component to generate a relatively precise and stable levitation force. This ensures that the launch vehicle component always maintains a stable levitation state in the vacuum launch tube, avoiding collisions or friction with the track due to unstable levitation, and ensuring the safety and reliability of the launch process.

[0028] Furthermore, the magnetic levitation electromagnetic component is placed on the side of the electromagnetic propulsion component closer to the launch track. The figure-eight coil only serves to provide levitation force for the launch vehicle and will not interfere with the electromagnetic propulsion component providing propulsion force to the launch vehicle.

[0029] The embodiments of this application also disclose a magnetically levitated guided three-section vacuum electromagnetic catapult waverider launch system. The launch vehicle is configured as a launch vehicle, which includes a vehicle frame, a launch platform on the top of the vehicle frame, a "T" shaped groove on the bottom of the vehicle frame, a rotating baffle at one end of the vehicle frame, the rotating baffle being rotatably connected to the vehicle frame, and a hydraulic cylinder at the bottom of the rotating baffle, the output end of the hydraulic cylinder being connected to the rotating baffle.

[0030] A pantograph is also installed at the bottom center of the "T"-shaped groove, and the groove on the "T"-shaped track is adapted to the pantograph.

[0031] Using the above technical solution, the launch platform on top of the vehicle frame can carry the launched component. The output end of the hydraulic cylinder is connected to a rotating baffle, allowing adjustment of the baffle's angle to provide stable support for the launched component. Designing the power supply contact parts within a "T"-shaped groove and conductive groove improves power supply stability and safety.

[0032] The embodiments of this application also disclose a magnetically levitated guided three-stage vacuum electromagnetic catapult waverider launch system. The launched component is configured as a waverider, which is located on top of the carrier launch component. The waverider has multiple internal support frames inside, each of which is triangular in shape. The multiple internal support frames are spaced apart along the length direction of the waverider. Furthermore, the waverider includes a first-stage propulsion component and a second-stage propulsion component that can be separated.

[0033] The aforementioned technical solution incorporates multiple triangular internal support frames spaced apart along the length of the waverider. The triangle's high stability allows the internal support frames to effectively distribute and transfer stress under various external forces, enhancing the overall structural strength of the waverider. This is particularly beneficial when the waverider passes through the curved transition section, where it experiences higher loads; the waverider body can withstand even greater loads. The waverider employs detachable first and second-stage propulsion components, enabling second-stage propulsion and separation after launch, further improving flight speed and efficiency.

[0034] The embodiments of this application also disclose a magnetically levitated guided three-stage vacuum electromagnetic catapult waverider launch system, wherein the angle between the primary acceleration section and the horizontal direction is in the range of 20° to 30°, the central angle of the arc transition section is in the range of 60° to 70°, and the angle between the acceleration launch section and the horizontal direction is 90°.

[0035] The buffer landing track includes a landing tube and a magnetic levitation landing guide track. The magnetic levitation landing guide track is fixed inside the landing tube, and the coil in the magnetic levitation landing guide track is energized in the opposite direction to the coil in the launch track.

[0036] By adopting the above technical solution, the angle between the primary acceleration section and the horizontal direction is set within the range of 20° - 30°, which can ensure that the wave rider is stably accelerated. The primary acceleration section is set with a small angle, which can reduce the central angle of the arc transition section, enabling the wave rider to smoothly transition from the inclined acceleration state of the primary acceleration section to the vertical acceleration state of the acceleration launch section, and reducing energy loss. The angle between the acceleration launch section and the horizontal direction is 90°. The carrier launch component carries the wave rider, accelerates from the primary acceleration section, and gradually transitions through the arc transition section to the vertical acceleration launch section, and finally launches vertically. The primary acceleration section, the arc transition section, and the acceleration launch section transition smoothly, which improves the stability and reliability of the launch system.

[0063] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0064] This embodiment discloses a magnetically levitated guided three-stage vacuum electromagnetic catapult waverider launch system. Please refer to [link to relevant documentation]. Figure 1 The launch system includes a launch track 100, a buffer landing track 200, and a launch vehicle 300. The tail end of the launch track 100 is connected to the head end of the buffer landing track 200, and the tail end of the buffer landing track 200 is connected to the head end of the launch track 100. The launch vehicle 300 can reciprocate along the launch track 100 and the buffer landing track 200.

[0065] It should be noted that, in this embodiment, the connection between the tail end of the launch track 100 and the head end of the buffer landing track 200 refers to a spatial connection, forming a continuous path, or a physical connection, allowing the launch vehicle 300 to smoothly move from the tail end of the launch track 100 to the head end of the buffer landing track 200. Similarly, the connection between the tail end of the buffer landing track 200 and the head end of the launch track 100 also refers to a direct spatial connection, forming a continuous path, allowing the launch vehicle 300 to smoothly move from the tail end of the buffer landing track 200 to the head end of the launch track 100. In other words, the launch track 100 and the buffer landing track 200 form a closed loop structure, ensuring that the launch vehicle 300 can move back and forth along both the launch track 100 and the buffer landing track 200.

[0066] Further, see also Figure 1 and Figure 2The launch track 100 includes a primary acceleration section 110, an arc-shaped transition section 120, and an acceleration launch section 130 connected sequentially along the launch direction of the launch track 100. The primary acceleration section 110 extends obliquely in the horizontal direction, the arc-shaped transition section 120 is arc-shaped, and the acceleration launch section 130 extends in the vertical direction.

[0067] The launch direction of launch trajectory 100 refers to the direction from the beginning to the end of launch trajectory 100. Figure 1 The bottom of the launch orbit 100 is the bow end, and the top is the tail end; that is, the launch direction of the launch orbit 100 is... Figure 1 The direction from bottom to top.

[0068] The launcher 300 carries the launchee 400, and the launcher 300 accelerates sequentially from the beginning of the launch track 100 through the primary acceleration section 110, the arc transition section 120 and the acceleration launch section 130 before launching the launchee 400 in a vertical direction.

[0069] In this embodiment, acceleration mechanisms may be provided in the primary acceleration section 110, the arc-shaped transition section 120, and the acceleration launch section 130, or acceleration mechanisms may be provided only in the primary acceleration section 110 and the acceleration launch section 130, with the arc-shaped transition section 120 serving as a turning transition. The acceleration mechanism may be an electromagnetic acceleration device, such as an electromagnetic catapult mechanism in this embodiment.

[0070] More specifically, in this embodiment, the tilt angle of the primary acceleration unit 110 along the horizontal direction is not limited. For example, the tilt angle can be 5°, 10°, 15°, 20°, etc. When the acceleration launch unit 130 extends along the vertical direction, the acceleration launch unit 130 can have an angle of 90° with the horizontal plane, or it can be any value within 80°~90°, such as 80°, 85°, etc., with a certain angle with the vertical direction. This embodiment does not limit this to a single value.

[0071] By adopting the design of this application, the launch trajectory 100 of the launch system disclosed in this application includes a primary acceleration section 110, an arc-shaped transition section 120, and an acceleration launch section 130. The arc-shaped transition section 120 is set in an arc shape, which allows for a smoother turning process for the launch vehicle 300. The launch vehicle 300 and its mounted payload 400 experience uniform force during turning, avoiding the enormous impact force and high overload caused by sudden turning. This ensures the stability of the payload 400's flight attitude during launch, improves launch accuracy and success rate, and solves the problem of unsmooth turning in the prior art.

[0072] Furthermore, the tail end of the launch track 100 is connected to the head end of the buffer landing track 200, and the tail end of the buffer landing track 200 is also connected to the head end of the launch track 100, forming a closed-loop track system. This eliminates the need for a blocking component at the tail end of the launch track 100, and avoids the problem of the launch vehicle component 300 flying out or becoming unusable after a single launch. After completing its launch mission, the launch vehicle component 300 decelerates and returns to the head end of the launch track 100 due to inertia within the buffer landing track 200, achieving convenient and efficient recovery of the launch vehicle component 300. This avoids the impact of high-speed return or high-speed stopping, reduces the risk during recovery, and thus improves the service life of the launch system.

[0073] In other words, after launching the rocket, the launch vehicle 300 can return to its initial position or launch position along the buffer return track 200, which is connected to the launch track 100. The buffer return track 200 allows the launch vehicle 300 to automatically, smoothly and accurately slide back to the launch origin, ready for the next launch, thereby achieving high-frequency continuous launches, reducing launch costs and shortening the launch cycle.

[0074] This application also discloses a magnetically levitated guided three-stage vacuum electromagnetic catapult waverider launch system. Please refer to [link to relevant documentation]. Figure 1 A first arc-shaped connecting track 500 is provided between the tail end of the launch track 100 and the head end of the buffer landing track 200, and a second arc-shaped connecting track 600 is provided between the tail end of the buffer landing track 200 and the head end of the launch track 100. The launch track 100, the first arc-shaped connecting track 500, the buffer landing track 200, and the second arc-shaped connecting track 600 are sequentially connected to form a circular track. After the launch vehicle 300 launches the launched component 400 through the launch track 100, it sequentially passes through the first arc-shaped connecting track 500, the buffer landing track 200, and the second arc-shaped connecting track 600 to return to the head end of the launch track 100. The design of this application, with its first arc-shaped connecting track 500 and second arc-shaped connecting track 600, allows for a smoother transition of the launch vehicle 300 between the launch track 100 and the buffer landing track 200. The arc-shaped track provides a gentler transition, avoiding impacts and vibrations. The circular track construction makes the entire launch system more compact and rational in structure. Please refer to... Figure 1 and Figure 2 The bottom of the circular track is also equipped with a track support 700 to provide stable support for the circular track, so as to provide a launch base for the tail end of the launch track 100 and the buffer landing track 200.

[0075] This embodiment also discloses a magnetically levitated guided three-stage vacuum electromagnetic catapult waverider launch system. Please refer to [link to relevant documentation]. Figure 1 , Figure 2 as well as Figure 3 It also includes a vacuum launch pipe 800, and a launch track 100 is disposed inside the vacuum launch pipe 800. The vacuum launch pipe 800 extends in the same direction as the extension direction of the launch track 100.

[0076] Please continue reading Figure 4 The vacuum emission pipe 800 includes a plurality of vacuum pipes 810 that are sequentially sealed and spliced ​​along its axial direction. A vacuum bellows 820 is also sealed between two adjacent vacuum pipes 810. The outer wall of each vacuum pipe 810 is provided with a plurality of vacuum tube interfaces 811 at intervals along the circumference. Each vacuum tube interface 811 is connected to a vacuum pump (not shown in the figure).

[0077] Specifically, in this embodiment, the number of vacuum pipes 810 is not limited and is designed and selected according to the length of the vacuum emission pipe 800. The number of vacuum tube interfaces 811 on the outer wall of each vacuum pipe 810 is also not limited. For example, one or more rings of vacuum tube interfaces 811 can be evenly arranged along the circumference of the vacuum pipe 810. Each ring of vacuum tube interfaces 811 includes multiple uniformly distributed vacuum tube interfaces 811. With this structure, multiple vacuum tube interfaces 811 are connected to a vacuum pump. The vacuum pump works and evacuates the vacuum pipe 810 to about 1000 Pa, which greatly reduces air resistance, activates the heating effect, and suppresses sonic booms. Preferably, sealing gates are provided at the beginning and end of the vacuum emission pipe 800. The sealing gates can be controlled to open or close to create a vacuum environment inside the vacuum emission pipe 800.

[0078] This structural design provides a near-vacuum launch environment for the launch track 100 via the vacuum launch pipe 800, significantly reducing space resistance and thus improving launch speed and efficiency. The vacuum launch pipe 800 employs a sealed splicing method using multiple vacuum pipes 810, facilitating installation and assembly. This allows for the easy construction of longer launch pipes to meet the needs of different launch track lengths. A vacuum bellows 820 is sealed between adjacent vacuum pipes 810. The vacuum bellows 820 possesses excellent flexibility and sealing properties, compensating for minor displacements and deformations of the vacuum pipes 810 caused by temperature changes, installation errors, or external vibrations. Furthermore, the vacuum bellows 820 can be easily bent at various angles and spliced ​​into a smooth, arc-shaped transition section 120.

[0079] Furthermore, it should be noted that, see Figure 1In the magnetically levitated guided three-section vacuum electromagnetic catapult waverider launch system disclosed in this application, in addition to setting a launch track 100 and a buffer landing track 200, a first arc-shaped connecting track 500 and a second arc-shaped connecting track 600 are further set up so that the launch track 100, the first arc-shaped connecting track 500, the buffer landing track 200 and the second arc-shaped connecting track 600 are connected in sequence to form a circular track. In order to improve the launch speed and reduce resistance and energy loss, a vacuum launch pipe 800 is set on the launch track 100 based on this circular track. By combining the vacuum launch pipe 800 with the circular track, air resistance is greatly reduced and the launch speed is improved. Moreover, the vacuum launch pipe 800 is located outside the launch track 100 and will not affect or interfere with the return of the carrier launch component 300 to the initial position after launch.

[0080] This application also discloses a magnetically levitated guided three-stage vacuum electromagnetic catapult waverider launch system. Please refer to [link to relevant documentation]. Figure 5 and Figure 6 Inside the vacuum launch pipe 800, on both sides of the launch track 100 and the launch carrier 300 in the width direction, two sets of electromagnetic propulsion components 900 are also provided at intervals. Each set of electromagnetic propulsion components 900 extends along the length direction of the launch track 100. Each set of electromagnetic propulsion components 900 includes multiple electromagnetic drive coils 910 arranged sequentially along the length direction. The magnetic properties of any two adjacent electromagnetic drive coils 910 are opposite.

[0081] The launch vehicle 300 is provided with a moving coil group on both sides facing the two sets of electromagnetic propulsion components 900. Each moving coil group includes multiple moving coils 310. When the two sets of electromagnetic propulsion components 900 are energized, the multiple electromagnetic drive coils 910 interact with each other and jointly drive the moving coil group and the launch vehicle 300 to move along the launch direction of the launch track 100.

[0082] It should be noted that the interaction of the multiple electromagnetic drive coils 910 of the two sets of electromagnetic propulsion components 900 in the energized state means that any two adjacent electromagnetic drive coils 910 have opposite magnetisms, and the mover coils 310 of the mover coil group also have opposite magnetisms. Thus, when the mover coil group passes through the two sets of electromagnetic propulsion components 900 in sequence, opposite electromagnetic poles attract each other and like poles repel each other, propelling the carrier launch component 300 to accelerate along the launch direction of the launch track 100. It should be noted that the above-mentioned acceleration is a basic principle of electromagnetic catapult, which will not be elaborated on in this application.

[0083] The actual length of each electromagnetic propulsion assembly 900 can be set according to requirements, and multiple electromagnetic drive coils 910 are arranged sequentially along its length to ensure stable propulsion. The number of mover coils 310 in the mover coil group on the carrier launch component 300 is unlimited. For example, it can be 2, 3, 4, 5 or other numbers. In this embodiment, it is preferred to set 3 mover coils 310, and the 3 mover coils 310 are arranged side by side in sequence.

[0084] With the design of this application, two sets of electromagnetic propulsion components 900 are spaced apart on both sides of the launch track 100 and the launch vehicle 300. Each set includes multiple electromagnetic drive coils 910 arranged sequentially along the length of the launch track 100. The multiple electromagnetic drive coils 910 drive the launch vehicle 300 to move on the track. The electromagnetic drive coils 910 at different positions play their roles in sequence to provide continuous and stable thrust to the launch vehicle 300, ensuring that the launch vehicle 300 can accelerate quickly and smoothly to the required launch speed.

[0085] This embodiment also discloses a magnetically levitated guided three-stage vacuum electromagnetic catapult waverider launch system. Please refer to [link to relevant documentation]. Figure 6 and Figure 7 The launch track 100 is configured as a magnetic levitation track, and a magnetic levitation drive electromagnetic coil is installed on the magnetic levitation track. The launch carrier 300 is equipped with a magnetic levitation electromagnetic coil 320 adapted to the magnetic levitation drive electromagnetic coil.

[0086] With this structural design, the magnetic levitation drive electromagnetic coil on the magnetic levitation track interacts with the magnetic levitation electromagnetic coil 320 on the launch vehicle 300, generating a stable electromagnetic force that suspends the launch vehicle 300 a certain distance above the launch track 100. This contactless levitation method eliminates the friction caused by traditional mechanical support structures, greatly reducing energy loss and allowing the launch vehicle 300 to be rapidly accelerated to launch speed, thereby reducing the length of the launch track 100.

[0087] This embodiment also discloses a magnetically levitated guided three-stage vacuum electromagnetic catapult waverider launch system. Please refer to [link to relevant documentation]. Figure 6 as well as Figure 7 The magnetic levitation track is set as a "T" shaped track. A "T" shaped track means that the track connection structure above the track cross section is larger than the track support structure below. The launch vehicle component 300 is provided with a "T" shaped groove that is adapted to the "T" shaped track.

[0088] The “T”-shaped track also has a groove 140 in the middle of its width direction. The groove 140 extends along the length direction of the magnetic levitation track, and a power supply cable is installed inside the groove 140.

[0089] For further comparison, see [link / reference] Figure 6 and Figure 8 The launch vehicle 300 is configured as a launch vehicle, such as a skid. The launch vehicle includes a vehicle frame 330, a launch platform 340 on the top of the vehicle frame 330, a "T"-shaped groove at the bottom of the vehicle frame 330, and a rotating baffle 350 at one end of the vehicle frame 330. The rotating baffle 350 is rotatably connected to the vehicle frame 330, and a hydraulic cylinder 360 is also provided at the bottom of the rotating baffle 350. The output end of the hydraulic cylinder 360 is connected to the rotating baffle 350 and abuts against one side of the rotating baffle 350 in the thickness direction. By controlling the extension length of the output end of the hydraulic rod, the tilt angle of the rotating baffle 350 can be controlled. The rotation angle of the rotating baffle 350 is preferably set to be able to rotate within the range of 0~90°.

[0090] See also Figure 7 and Figure 8 A pantograph 370 is also provided at the bottom center of the "T"-shaped groove, and the groove 140 on the "T"-shaped track is adapted to the pantograph 370.

[0091] This structural design, where the "T"-shaped track and the "T"-shaped groove on the launch vehicle 300 cooperate with each other, provides more reliable guidance for the launch vehicle 300. The "T"-shaped structure can constrain it in both horizontal and vertical directions, effectively preventing the launch vehicle 300 from shifting left and right or swaying up and down during high-speed movement, thus improving the accuracy and stability of the launch. Furthermore, placing the power supply cable within the groove 140 can protect the power supply cable.

[0092] The transport platform 340 on top of the vehicle frame 330 can carry the launched component 400. The output end of the hydraulic cylinder 360 is connected to the rotating baffle 350, which can adjust the angle of the rotating baffle 350 to provide stable support for the launched component 400. The power supply contact part is designed in the "T" shaped groove and conductive groove, which improves the stability and safety of power supply.

[0093] This embodiment also discloses a magnetically levitated guided three-stage vacuum electromagnetic catapult waverider launch system. Please refer to [link to relevant documentation]. Figure 6 and Figure 10 Inside the vacuum launch pipe 800, each electromagnetic propulsion assembly 900 is also equipped with a magnetic levitation electromagnetic assembly on one side, which is located on the side of the electromagnetic propulsion assembly 900 close to the launch track 100.

[0094] The electromagnetic drive coil 910 is configured as a loop coil, and the magnetic levitation electromagnetic assembly includes a plurality of magnetic levitation coils 920 arranged sequentially along the length of the launch track 100. (See [link]) Figure 10Each magnetic levitation coil 920 is configured as an "8" shaped coil.

[0095] This structural design gives the figure-eight coil unique magnetic field distribution characteristics. When current passes through the figure-eight coil, a specific magnetic field is generated around it, which interacts with the corresponding magnetic levitation structure on the launch vehicle 300 to produce a relatively precise and stable levitation force. This ensures that the launch vehicle 300 remains in a stable levitation state within the vacuum launch tube 800, avoiding collisions or friction with the track due to unstable levitation, and guaranteeing the safety and reliability of the launch process.

[0096] Furthermore, the magnetic levitation electromagnetic component is placed on the side of the electromagnetic propulsion component 900 close to the launch track 100. The figure-eight coil only serves to provide levitation force to the launch vehicle 300 and will not interfere with the electromagnetic propulsion component 900 providing propulsion force to the launch vehicle 300.

[0097] This embodiment also discloses a magnetically levitated guided three-stage vacuum electromagnetic catapult waverider launch system. Please refer to [link to relevant documentation]. Figure 9 The launched component 400 is configured as a waverider, which is located on top of the launch component 300. The waverider has multiple internal support frames 410 inside, each of which is triangular in shape. The multiple internal support frames 410 are spaced apart along the length of the waverider. The waverider includes a first-stage propulsion component 420 and a second-stage propulsion component 430 that can be separated.

[0098] This structural design incorporates multiple triangular internal support frames 410 spaced along the length of the waverider. The triangle shape provides exceptional stability, allowing the internal support frames 410 to effectively distribute and transfer stress under various external forces, thus enhancing the overall structural strength of the waverider. Particularly when the waverider passes through the arc-shaped transition section 120, it experiences higher loads, and the waverider body can withstand even greater loads. For example, in this embodiment, with the turning radius of the arc-shaped transition section 120 set to 900m, the turning angle to 60°-70°, the inlet tilt angle to 20°-30°, and the outlet tilt angle to 90°, the overload during the waverider's passage through the arc-shaped transition section 120 can reach approximately 13.1g. This waverider with internal support frames 410 exhibits higher structural strength, capable of withstanding overloads of approximately 25G, ensuring successful launch.

[0099] The waverider employs a separable first-stage propulsion component 420 and a second-stage propulsion component 430. After launch, it can also achieve second-stage propulsion and second-stage separation. After the engines of the first-stage propulsion component 420 and the second-stage propulsion component 430 are ignited, they can continue to climb and accelerate, further improving flight speed and efficiency.

[0100] The embodiment of this invention also discloses a magnetically levitated guided three-stage vacuum electromagnetic catapult waverider launch system, wherein the angle between the primary acceleration section 110 and the horizontal direction is in the range of 20°-30°, the central angle of the arc transition section 120 is in the range of 60°-70°, and the angle between the acceleration launch section 130 and the horizontal direction is 90°.

[0101] Furthermore, the buffer landing track 200 includes a landing tube 210 and a magnetic levitation landing guide track 220. The magnetic levitation landing guide track 220 is fixed inside the landing tube 210, and the energizing direction of the coil inside the magnetic levitation landing guide track 220 is opposite to the energizing direction of the coil inside the launch track 100.

[0102] In this embodiment, the angle between the primary acceleration section 110 and the horizontal direction is set within the range of 20°-30° to ensure that the waverider is stably accelerated. The angle between the primary acceleration section 110 and the horizontal direction can be 20°, 25°, 30°, etc., and the central angle of the arc transition section 120 can be 60°, 65°, 70°, or other angles. For example, when the angle between the primary acceleration section 110 and the horizontal direction is 20°, the central angle of the arc transition section 120 is 70°. When the angle between the primary acceleration section 110 and the horizontal direction is 25°, the central angle of the arc transition section 120 is 65°. That is to say, the sum of the angle between the primary acceleration section 110 and the horizontal direction and the central angle of the arc transition section 120 is 90° to meet the requirement of the waverider being accelerated from horizontal to vertical.

[0103] With this structural design, the primary acceleration section 110 is set with a small angle, which can reduce the central angle of the arc transition section 120. This allows the waverider to smoothly transition from the inclined acceleration state of the primary acceleration section 110 to the vertical acceleration state of the acceleration launch section 130, and reduces energy loss. The acceleration launch section 130 has an angle of 90° with the horizontal direction. The carrier launch component 300 carries the waverider, which accelerates from the primary acceleration section 110 and gradually transitions through the arc transition section 120 to the vertical acceleration launch section 130, and finally launches vertically. The smooth transition between the primary acceleration section 110, the arc transition section 120, and the acceleration launch section 130 improves the stability and reliability of the launch system.

[0104] Finally, a brief description is given of the specific process of launching the waverider in the magnetically levitated guided three-stage vacuum electromagnetic catapult waverider launching system disclosed in this invention:

[0105] Before preparing for launch, please see Figure 1 and Figure 5The launch platform 340 of the launch vehicle component 300 carries the launchee 400 located at the head end of the primary acceleration section 110 of the launch track 100. In this embodiment, the launchee 400 is a waverider, with a total weight of 1 ton and a total length of 1 meter. At this time, the air pressure in the vacuum launch pipe 800 is evacuated to about 1000 Pa. When ready to launch, multiple electromagnetic drive coils 910 of the electromagnetic propulsion component 900 are energized in sequence, and the launch vehicle is propelled by electromagnetic propulsion. The component 300 and the waverider are accelerated in the vacuum pipe 810 and pass through the primary acceleration section 110, the arc transition section 120 and the acceleration launch section 130 in sequence. They can be accelerated to Mach 1 in the vacuum launch pipe 800. In the arc transition section 120, the waverider is subjected to an overload of about 13.1g. Finally, the waverider is vertically launched from the acceleration launch section 130. The waverider can also continue to climb and accelerate after the engines of the first-stage propulsion component 420 and the second-stage propulsion component 430 are ignited.

[0106] After the launch vehicle 300 launches the waverider, it passes through the first arc-shaped connecting track 500, the buffer return track 200, and the second arc-shaped connecting track 600 in sequence before returning to the head of the primary acceleration section 110, ready for the next launch. When the launch vehicle 300 returns, the rotating baffle 350 can be adjusted to 90 degrees to increase resistance and decelerate. In addition, the energizing direction of the coil in the magnetic levitation return guide track 220 is opposite to the energizing direction of the coil in the launch track 100, which has a regenerative braking effect on the return of the launch vehicle 300 to reduce the return speed of the launch vehicle 300.
