[0002] Access to space is inseparable from launch vehicles, and the carrying capacity of these vehicles determines the effective payload size. Currently, rockets are the primary launch vehicles. Rockets generate thrust through high-temperature combustion in their engines, overcoming Earth's gravity to enter outer space. However, with the development of the space industry, the launch cycle, carrying capacity, and launch cost of rockets are no longer sufficient to meet the requirements of launch missions. Therefore, there is an urgent need to develop new launch vehicles. Currently, magnetic levitation electromagnetic propulsion is a promising advanced power technology. However, the application of magnetic levitation electromagnetic propulsion technology as a launch vehicle for spacecraft has not yet been systematically and thoroughly studied.

[0003] Existing launch vehicle systems are characterized by system complexity, high operating costs, long launch preparation time, and high maintenance and support difficulties, which seriously restricts human beings' ability to develop and utilize space. Summary of the Invention

The superconducting magnetic levitation electromagnetic propulsion module is used to lift the vehicle module, lift it off the slide rail surface and give it a certain speed. The air compression propulsion module converts the internal energy of the air into the kinetic energy of the vehicle module.

[0009] The electronic control module detects the moving speed of the carrier module and adjusts the electromagnetic linear propulsion power in real time to ensure effective coupling between air compression propulsion and electromagnetic linear propulsion, so that the carrier module can obtain the predetermined acceleration; a barrier module is set at the outlet of the vacuum pipeline module.

[0013] Furthermore, the movable sealing plate and drag-reducing cover at the end of the vacuum pipeline module travel at high speed under the action of the magnetic levitation electromagnetic propulsion module, expelling the air in the pipeline at the front of the carrier and creating a near-vacuum condition in front of the carrier; at the same time, the vacuum pump in the vacuum pipeline module further expels the gas in the pipeline.

[0014] Furthermore, the drag-reducing cover can be of a flowing, spherical, or planar shape, and the material can be a polymer, metal, ceramic, or resin-based composite material.

[0015] Furthermore, the air compression propulsion module includes: a compression push plate and a compression pump; the compression pump is mounted on the compression push plate, and the compression push plate is connected to the superconducting magnetic levitation electromagnetic propulsion module;

[0016] A movable enclosed space is formed between the compression push plate and the movable sealing plate at the tail. Gas is injected into the movable enclosed space by the compressed air pump on the compression push plate. The compression push plate moves quickly under the action of magnetic levitation and electromagnetic propulsion, compressing the air and realizing the conversion of the internal energy of the air into the kinetic energy of the aircraft module.

[0017] Furthermore, the gas filled in the movable enclosed space is air, argon, nitrogen, or helium.

[0018] Furthermore, the arresting module includes: arresting cables and arresting devices for use as a drag-reducing shield during launch.

[0019] Furthermore, the launch vehicle system operation mode includes 5 stages: start-up, acceleration I, orbit change, acceleration II, and launch; the travel distances of the four stages of start-up, acceleration I, acceleration II, and launch are represented by L0, L1, L2, and L3, respectively; the travel radius and orbit change angle of the orbit change stage are represented by R and θ, respectively.

[0020] Secondly,

[0021] This invention also proposes a launch method for a vehicle combining magnetic levitation, electromagnetic propulsion, and pneumatic propulsion, comprising:

[0022] Step 1: Preparation phase, secure the carrier to the transport skid;

[0023] Step 2: During the evacuation phase, the end movable sealing plate, the tail movable sealing plate, the carrier, and the carrier skid form mutually isolated chambers. The movable sealing push plate at the front end of the vacuum pipe is rapidly moved forward by electromagnetic propulsion, which quickly expels the air in the pipe section, creating a near-vacuum state in the pipe in front of the carrier.

[0024] Step 3: During the start-up phase, superconducting magnetic levitation electromagnetic propulsion is used to move the movable sealing plate at the tail, compressing the air behind the carrier to the required pressure.

[0025] Step 4: Acceleration Phase I. Unlock the launch vehicle's locked state and use the superconducting magnetic levitation electromagnetic propulsion module in conjunction with the high-pressure air generated behind the launch vehicle to accelerate the launch vehicle module; use the electronic control module to continuously drive the push plates at the front and rear ends of the launch vehicle to move in coordination, so as to achieve high-speed operation of the launch vehicle in a near-vacuum environment.

[0027] Step 6: Acceleration Phase II, using the superconducting magnetic levitation electromagnetic propulsion module and air compression module to further accelerate the launch vehicle module;

[0028] Step 7: During the launch phase, electromagnetic thrust is used to move the movable sealing plate at the front end away from the operating pipe, and the arresting device is used to stop the drag reduction shield, so that the launch vehicle that has achieved the target speed can leave the operating pipe and successfully take off.

[0029] The advantages of this invention compared to the prior art are:

[0030] The electromagnetic propulsion-assisted launch payload insertion scheme proposed in this invention can overcome the shortcomings of traditional chemical launch vehicles and has the following outstanding advantages:

[0031] (1) This invention proposes a technical solution for achieving efficient acceleration launch of a launch vehicle in the initial stage using non-chemical energy. This solution can fully utilize electrical energy to accelerate the launch vehicle in the initial flight stage, significantly reducing the size and complexity of the launch vehicle, greatly reducing its cost, and enabling high-frequency launches.

[0032] (2) Compared with the existing magnetic levitation transportation system, the present invention adopts a low aerodynamic resistance method with only vacuum pipes, which can eliminate the adverse effects of aerodynamic and thermal conditions on the entire system during the ground operation stage and greatly improve the speed limit of the magnetic levitation electric propulsion device.

[0033] (3) The pressurization and electromagnetic composite propulsion method proposed in this invention significantly increases the operating efficiency of the whole system and reduces the demand for peak power of the power supply system.

[0044] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings.

[0045] Traditional wheel-rail high-speed rail is limited by low operating speeds and high operating costs. In the future, developing higher-speed ground transportation systems is an inevitable requirement for national economic development. Maglev high-speed transportation systems based on the weak vacuum conditions of pipelines can achieve near-resistance-free operation, significantly increasing system speed while also leading to a substantial reduction in operating costs.

[0046] Based on magnetic levitation electromagnetic propulsion technology, this invention further considers vacuum drag reduction conditions and air compression propulsion, and proposes a launch vehicle system that combines magnetic levitation electromagnetic propulsion and air compression propulsion. It can be used in ground transportation systems as well as for the ground acceleration and deployment of high-speed aircraft, and has broad application prospects.

[0047] like Figure 2 As shown, this invention proposes a vehicle system that combines magnetic levitation electromagnetic propulsion and air compression propulsion. The system includes: a vehicle module 1, a superconducting magnetic levitation electromagnetic propulsion module 2, an air compression propulsion module 3, a vacuum pipeline module 4, an electronic control module, an arresting module, and a slide rail 5.

[0048] The vacuum pipeline module 4 is equipped with a slide rail 5. The superconducting magnetic levitation electromagnetic propulsion module 2 is used to lift the carrier module 1, lift it off the surface of the slide rail 5 and give it a certain speed. The air compression propulsion module 3 converts the internal energy of the air into the kinetic energy of the carrier module.

[0049] The electronic control module detects the moving speed of the carrier module and adjusts the electromagnetic linear propulsion power in real time to ensure effective coupling between air compression propulsion and electromagnetic linear propulsion, so that the carrier module can obtain the predetermined acceleration; a barrier module is set at the outlet of the vacuum pipeline module.

[0050] like Figure 3 As shown, the carrier module includes: carrier 11, carrier skid 12, traction component 13 and fastener 14; the carrier skid 12 is mounted on the superconducting magnetic levitation electromagnetic propulsion module 2, the carrier 11 is fixed to the carrier skid 12 by the fastener 14, and the traction component 13 is used to connect the carrier skid 12 and the movable sealing plate in the vacuum pipeline module 4.

[0051] like Figure 4 As shown, the vacuum pipeline module 4 includes: a drag-reducing cover 41, an end movable sealing plate 42, a tail movable sealing plate 43, and a vacuum pump 44.

[0052] The drag-reducing cover 41 is mounted on the end movable sealing plate 42, and the vacuum pump 44 is mounted on the tail movable sealing plate 43; both the end movable sealing plate 42 and the tail movable sealing plate 43 are connected to the superconducting magnetic levitation electromagnetic propulsion module 2; the carrier module 1 is located between the end movable sealing plate 42 and the tail movable sealing plate 43, and the traction component 13 of the carrier module 1 is fixedly connected to the tail movable sealing plate 43.

[0053] The movable sealing plate and drag-reducing cover at the end of the vacuum pipeline module travel at high speed under the action of the magnetic levitation electromagnetic propulsion module, expelling the air in the pipeline at the front of the carrier and creating a near-vacuum condition in front of the carrier; at the same time, the vacuum pump in the vacuum pipeline module further expels the gas in the pipeline.

[0054] Preferably, the drag-reducing cover is of a flowing, spherical, or planar shape, and the material is a polymer material, a metal material, a ceramic material, or a resin-based composite material.

[0055] like Figure 5 As shown, the air compression propulsion module 3 includes: a compression push plate 31 and a compression air pump 32; the compression air pump 32 is mounted on the compression push plate 31, and the compression push plate 31 is connected to the superconducting magnetic levitation electromagnetic propulsion module 2;

[0056] A movable enclosed space is formed between the compression push plate 31 and the tail movable sealing plate 43. Gas is injected into the movable enclosed space by the compressed air pump 32 on the compression push plate 31. The compression push plate moves quickly under the action of magnetic levitation and electromagnetic propulsion to compress the air, realizing the conversion of the internal energy of the air into the kinetic energy of the aircraft module.

[0057] Preferably, the gas filled in the movable enclosed space is air, argon, nitrogen, or helium.

[0058] like Figure 6 As shown, the arresting module includes an arresting cable 51 and an arresting device 52, which are used to arrest and reduce drag during launch.

[0059] By utilizing a combination of magnetic levitation, electromagnetic propulsion, and compressed air propulsion technologies (or either technology alone), the launch vehicle can gain a certain flight speed from a stationary starting state, such as... Figure 1 As shown, the system operation mode of this invention typically includes five stages: startup, acceleration I, orbit change, acceleration II, and stable operation (or launch). The travel distances of the four stages of startup, acceleration I, acceleration II, and launch are represented by L0, L1, L2, and L3, respectively; the travel radius and orbit change angle of the orbit change stage are represented by R and θ, respectively.

[0060] The basic functions of the combined magnetic levitation electromagnetic propulsion and pneumatic propulsion vehicle system of this invention include the following:

[0061] 1. Mounting the Launch Vehicle: The launch vehicle can be fixed in a skid (when used in a ground transportation system, the skid itself can be used as the launch vehicle). The launch vehicle can be a rocket, a supersonic aircraft, a transport vehicle, or other similar device.

[0062] 2. Formation of a Vacuum Pipeline: The movable sealing plate and drag-reducing cover at the end of the vacuum pipeline module travel at high speed under the action of the magnetic levitation electromagnetic propulsion module, expelling the air from the pipeline at the front of the carrier and creating a near-vacuum condition in front of the carrier. Simultaneously, a vacuum pump within the vacuum pipeline module can be used to further expel the gas from the pipeline, achieving an even more ideal vacuum condition.

[0063] The drag-reducing cover can be in various shapes such as flowing, spherical, and planar, and the materials can be polymer materials, metal materials, ceramic materials, resin-based composite materials, etc.

[0064] 3. Independent Movement of the Movable Sealing Plate and Transport Skid: A superconducting magnetic levitation module is used to levitate the movable sealing plate, the transporter, and the transport skid, lifting them off the slide rail surface. An electromagnetic linear propulsion module is used to give the movable sealing plate, the transporter, and the transport skid a certain speed. An electronic control module is used to maintain the independent movement speed of the compression push plate, the end movable sealing plate, the tail movable sealing plate, the transporter, and the transport skid.

[0065] Superconducting magnetic levitation modules can be replaced by other levitation methods, such as magnetic levitation technology and acoustic levitation technology.

[0066] 4-Air Compression Propulsion Module: The compression pusher plate and the movable sealing plate at the rear form a movable enclosed space. Gas is injected into this space using a compressed air pump on the compression pusher plate. Under the action of magnetic levitation and electromagnetic propulsion, the compression pusher plate moves rapidly, compressing the air and converting the air's internal energy into the kinetic energy of the aircraft module.

[0067] The air filled into the enclosed space can also be replaced with other gases, such as argon, nitrogen, helium, etc.

[0068] 5. Acceleration and Control Mode: The electronic control module detects the moving speed of the sled module and adjusts the electromagnetic linear propulsion power in real time to ensure effective coupling between air compression propulsion and electromagnetic linear propulsion, enabling the sled to achieve efficient acceleration.

[0069] 6-Repeated use of propulsion mode: Repeat basic functions 2, 3, 4, and 5 to achieve real-time coupling of air compression propulsion and electromagnetic linear propulsion, enabling the sled to obtain efficient acceleration.

[0070] 7-Arresting Drag Reduction Shield: Used during aircraft launch, it uses an arresting device to block the drag reduction shield in the aircraft module, thereby preventing the drag reduction shield from hindering the aircraft launch.

[0071] The specific implementation process of the entire system of this invention includes the following steps:

[0072] Step 1: Preparation stage. For example... Figure 2 , 3 As shown, the carrier is fixed in the carrier skid module.

[0073] Step 2: Vacuuming stage. For example... Figure 2 , 4 As shown, the movable end sealing plate, the movable tail sealing plate, the aircraft, and the transport skid module constitute mutually isolated chambers. The movable sealing pusher plate at the front end of the electromagnetic propulsion pipe moves rapidly forward, quickly expelling air from the pipe section and creating a near-vacuum state in the pipe ahead of the launch vehicle.

[0074] Step 3: Startup Phase. For example... Figure 1 , 2 As shown, superconducting magnetic levitation electromagnetic propulsion is used to move the sealed push plate at the tail, compressing the air behind the carrier to the required pressure.

[0075] Step 4: Accelerate Phase I. For example... Figure 1 , 2 As shown in Figures 4 and 5, the launch vehicle is unlocked, and the superconducting magnetic levitation electromagnetic propulsion module, combined with the high-pressure air generated behind the launch vehicle, accelerates the launch vehicle module. The electronic control module continuously drives the coordinated movement of the front and rear pushers of the launch vehicle, enabling high-speed operation in a near-vacuum environment. The optimal aerodynamic design of the front pusher reduces air resistance during high-speed operation and ensures continuous operation of the launch vehicle in a vacuum environment. The rear pusher, in addition to providing initial acceleration thrust, also provides continuous pressurization throughout the entire operation of the launch vehicle.

[0076] Step 5: Track Change Phase. For example... Figure 1 As shown, the vehicle module, vacuum pipeline module, and air compression module can change their speed direction while maintaining straight-line movement by using a sliding rail to change their track.

[0077] Step 6: Accelerate Phase II. (e.g.) Figure 1 As shown, the launch vehicle module is further accelerated by using a superconducting magnetic levitation electromagnetic propulsion module and an air compression module.

[0078] Step 7: Launch Phase (only applicable to aircraft). For example... Figure 1 , 6 As shown, electromagnetic thrust is used to propel the front push plate away from the operating pipe, and an arresting device is used to stop the push plate and the drag reduction shield, so that the aircraft that has obtained the target speed can leave the operating pipe and take off smoothly.

[0079] This invention utilizes electromagnetic propulsion via magnetically levitated rails to achieve efficient initial acceleration for ground-launched launch vehicles. This technology can be further extended to propellant-free spacecraft launches from the lunar surface. The invention achieves the required boost speed and optimal launch angle through long-distance linear acceleration supplemented by utilizing terrain slope to change the velocity direction. Simultaneously, this invention proposes a novel duct evacuation technology based on electromagnetically driven push plates, enabling extremely rapid air removal from the spacecraft's operating ducts, thus providing a low dynamic pressure environment for subsequent launch. This invention achieves rapid pressurization and energy storage, providing thrust for the rocket's ground boost phase and reducing the power requirements of the electromagnetic launch phase.
