[0001] The present application relates to the technical field of magnetic levitation launch sled vehicles, in particular to a launch sled vehicle adopting electromagnetic suspension and propulsion. BACKGROUND

[0002] The high-speed electromagnetic propulsion device is a device for converting electric energy into kinetic energy by using electromagnetic force. The high-speed electromagnetic propulsion device uses electric energy as energy source, has lower cost than rocket propellant, is controllable, can be used repeatedly, has large acceleration and high limit speed. The high-speed electromagnetic propulsion device can be applied to transportation, logistics, aerospace, military and other fields.

[0003] The sled vehicle of the electric dynamic suspension (EDS) system generates induced current and induced magnetic field by cutting the ground coil with the magnetic field of the vehicle-mounted magnet when the sled vehicle runs. The magnetic field of the vehicle-mounted magnet and the induced magnetic field of the ground coil interact to generate electromagnetic suspension force and guiding force, so as to realize the suspension and guidance of the sled vehicle. The system has the characteristics of high load capacity, large suspension height and low track precision requirement.

[0004] The existing magnetic suspension sled vehicle and rocket sled usually use steel rails and sliding shoes to realize support and guidance. On the one hand, the sliding friction between the sliding shoes and the steel rails hinders the movement of the rocket sled in the longitudinal direction, which affects the propulsion efficiency of the rocket sled to some extent. On the other hand, the unevenness of the steel rails and the collision between the sliding shoes and the steel rails caused by the attitude change of the rocket sled will intensify the vibration of the rocket sled, which is more significant at high speed.

[0009] The traction beam is connected with the propulsion magnet and the main beam, and is used for transmitting traction braking force and guiding force generated by the propulsion magnet to the main body of the sled vehicle and the load. The propulsion magnet is located at the lower side of the traction beam.

[0010] The suspension beam connects the suspension magnet and the side beam, and is used to transfer the suspension force generated by the suspension magnet and the guiding force to the sled body and the load.

[0011] The slide shoe mounting beam connects the slide shoe and the side beam, and is used to transfer the support and guiding force generated by the interaction between the slide shoe and the guide rail in the emergency working condition. The slide shoe mounting beam is located on the outer side of the side beam, and the slide shoe is located on the slide shoe mounting beam.

[0012] Preferably, the number of the propulsion magnets is multiple, and the multiple propulsion magnets are longitudinally arranged on the lower side of the traction beam.

[0013] Preferably, the propulsion magnets are fixedly connected with the traction beam through bolts.

[0014] Preferably, the number of the suspension magnets is multiple, and the suspension magnets are arranged on the lower side of both ends of the suspension beam.

[0015] Preferably, the suspension magnets are fixedly connected with the suspension beam through bolts.

[0030] Through the above technical scheme, the direct contact between the sled body and the ground can be isolated, and unnecessary vibration and friction resistance in the advancing direction caused by the unevenness of the ground and the steel rail can be reduced; compared with the traditional rocket sled, the scheme adopts the linear motor to drive the sled, so that the steps such as filling of rocket fuel can be omitted, and the sled can be repeatedly and repeatedly launched.

[0031] In other words, the present application adopts the non-contact electromagnetic propulsion and suspension form, optimizes the external excitation input form of the sled, reduces the propulsion resistance and external vibration excitation of the sled on the basis of meeting the characteristics of large thrust and large load, improves the running stability and stability of the sled, and improves the propulsion performance of the sled. Meanwhile, compared with the mode of using rocket propulsion as a power source, the cost of single launch of the sled using electromagnetic propulsion mode will also be greatly reduced.

[0032] The launch sled adopting the electromagnetic suspension and propulsion form described in the present application can be used as a space launch sled.

[0033] According to an embodiment of the present application, the number of propulsion magnets 7 is multiple, and the multiple propulsion magnets 7 are arranged in a longitudinal direction at the lower side of the traction beam 10.

[0034] That is, the multiple propulsion magnets are arranged in a longitudinal arrangement manner at the lower side of the traction beam.

[0035] According to an embodiment of the present application, the propulsion magnet 7 is fixedly connected with the traction beam 10 through a bolt.

[0036] According to an embodiment of the present application, the number of suspension magnets 6 is multiple, and the suspension magnets 6 are arranged at the lower side of both ends of the suspension beam 8.

[0038] According to one embodiment of the present invention, the levitation magnet and the propulsion magnet include an outer Dewar, a superconducting coil, an inner Dewar, a support member, and a refrigerant device.

[0039] The launch skid employing electromagnetic levitation and propulsion as described in this invention is described below with reference to examples. The launch skid includes:

[0040] The system consists of one main beam (3), two side beams (1), multiple crossbeams (2), multiple aerodynamic surfaces (4), one traction beam (10), two suspension beams (8), four skid mounting beams (5), four skids (9), three propulsion magnets (7), and four suspension magnets (6). The main beam (3) connects the traction beam (10), crossbeams (2), and aerodynamic surfaces (4), bearing traction and braking forces. The side beams (1) connect the suspension beams (8), crossbeams (2), and aerodynamic surfaces (4), bearing levitation forces. The traction beams (10) connect the propulsion magnets (7) and the main beam (3), transmitting traction and braking forces and guiding forces generated by the propulsion magnets to the skid structure and load. The suspension beams (8) connect the suspension magnets (6) and the side beams (1), transmitting levitation forces and guiding forces generated by the suspension magnets (6) to the skid structure and load. The skid mounting beams (5) connect the skids (9) and the side beams (1), transmitting support and guiding forces generated by the interaction between the skids and guide rails in emergency situations.

[0041] Each propulsion magnet consists of one outer Dewar, two superconducting coils, two inner Dewars, eight support components, and multiple refrigerant devices. The propulsion magnet provides a strong magnetic field, achieving traction and braking under the action of a ground-based linear motor. Each levitation magnet consists of one outer Dewar, one superconducting coil, one inner Dewar, four support components, and several refrigerant devices. The levitation magnet provides a strong magnetic field, which cuts the ground-based levitation guide coil to generate levitation and guiding forces. Three propulsion magnets can be arranged longitudinally and sequentially bolted to the traction beam. Four levitation magnets are positioned at the four corners of the skid and bolted to the levitation beam. The electromagnetic load generated by the magnets is transmitted along the path of superconducting coil-inner Dewar-support component-outer Dewar-traction beam / levitation beam. The remaining equipment is installed on the top equipment platform.

[0042] As can be seen from the above embodiments, the present invention employs a launch skid with electromagnetic levitation and propulsion, supported, guided, and propelled by a superconducting magnet. The superconducting magnet achieves ultra-high propulsion acceleration while avoiding direct contact between the skid body and the rails. These features not only reduce frictional resistance in the skid's forward direction but also isolate vibrations caused by unevenness in the rails and roadbed, effectively improving the skid's operational smoothness and stability.

[0043] In the description of the application, it should be understood that the orientation words such as "front, back, upper, lower, left, right", "transverse, vertical, perpendicular, horizontal" and "top, bottom" and the like indicated orientation or position relationship are generally based on the orientation or position relationship shown in the drawings, only for the convenience of describing the application and simplifying the description, without making the opposite statement, these orientation words do not indicate and imply that the device or element referred to must have a particular orientation or be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the scope of protection of the application; the orientation words "inner, outer" refer to the inner and outer of the contour of each component itself.

[0044] For the convenience of description, spatial relative terms such as "over", "above", "upper surface", "upper" and the like can be used herein to describe the spatial position relationship of one device or feature with other devices or features as shown in the drawings. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the drawings. For example, if the device in the drawing is inverted, the device described as "above" or "over" other devices or structures will be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below" orientations. The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein are interpreted accordingly.

[0045] In addition, it should be noted that the use of "first", "second" and the like to define parts only facilitates the differentiation of corresponding parts, and the above words have no special meaning unless otherwise stated, and therefore cannot be understood as a limitation on the scope of protection of the application.

For those skilled in the art, the application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the application shall be included in the scope of protection of the application.
