Description

Technical Field

[0001] The present application relates to the field of rocket launch technology, and in particular to a three-level mode test and launch system for a large carrier rocket and a rocket launch method. Background Art

[0002] At present, there are three main test and launch modes commonly used by launch vehicles in various countries around the world: one horizontal and two vertical (horizontal transfer of rockets, vertical assembly, vertical testing), three vertical (vertical transfer of rockets, vertical assembly, vertical testing) and three horizontal (horizontal transfer of rockets, horizontal assembly, horizontal testing). These three test and launch modes have their own advantages and disadvantages and are used in rocket launch processes at home and abroad. Most civilian and commercial space rockets use the three-horizontal test and launch mode, and the equipment composition and launch process of each large rocket test and launch system are different.

[0003] Civilian and commercial aerospace uses rockets with a three-horizontal test and launch mode. The launch process is generally as follows: the rocket is assembled and tested in the technical area, the rocket is transferred to the launch station using a general-purpose transport vehicle, and the rocket is transferred to the erection frame using a truck-mounted crane to erect the rocket. Alternatively, a special erection transport vehicle is used to transport the rocket to the launch station, the erection frame is docked with the launch pad, and the rocket is erected. For rockets that use a three-vertical test and launch mode, the vertical assembly and test plant is relatively close to the launch station, usually about 2 kilometers, and generally has rails laid. The entire rocket is vertically transported using a mobile launch platform, and there are no obstacles during transportation.

[0004] Some rockets in the civilian and commercial aerospace industry are equipped with a mobile plant at the launch station, which can protect the launch station equipment and horizontal rockets. After the rocket completes the horizontal test in the technical area, it is transferred to the erection frame and pre-launch preparations are carried out in the mobile plant. Before the rocket is erected, the mobile plant is evacuated to a safe area. After the rocket is launched, the mobile plant is moved back to the launch station to prevent dust, rain, and sunlight, and to protect the erection frame, launch pad and other front-end equipment. Rockets that use the three-vertical test launch mode are usually equipped with a fixed launch tower, and the tower platform is closed to form a closed space to protect the rocket body. The platform is opened before launch, which does not affect the rocket's takeoff.

[0005] At present, civilian and commercial rockets are generally built in technical areas or borrowed from technical factories. The distance for transporting the rocket from the technical factory to the launch site is about several kilometers to tens of kilometers. The transfer of the entire rocket generally requires the use of horizontal transportation equipment.

[0006] At present, the shortcomings of the existing large-scale launch vehicle test and launch system are: a large rocket has a total length of more than 70 meters, and the transportation height in the horizontal transportation state is more than 10 meters, which exceeds the height of the existing technical factory door. It is inconvenient to transport the entire rocket in and out of the factory, and the existing technical factory needs to be modified. If other methods are used to transfer the rocket to the transport vehicle, the operation process will be increased. The transportation of the entire rocket is super high and super long, and the requirements for the passage road are high. The turning radius is required to be greater than 90 meters, and the existing road needs to be modified. The passing height is required to exceed 10 meters, and the traffic lights and other equipment along the way need to be removed. Considering the need for multi-station launch of rockets, the test equipment needs to be movable and used in other launch sites.

[0007] Therefore, the technical problem that urgently needs to be solved is: how to provide a three-level mode test and launch system for a large-scale carrier rocket and a rocket launch method to solve the problem of inconvenient transportation of the entire rocket at a lower cost.

[0033] The following is a clear and complete description of the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0034] like Figure 1 As shown, the present application provides a three-level mode test and launch system for a large-scale carrier rocket, which includes: a factory building 1, rails 2, a wheeled vehicle 3, a hoist 4, a truck crane 5, an erection frame 6 and a launch platform 7, and a gantry crane is arranged in the factory building 1. The rails 2 are laid from the factory building 1 and extend outward to the launch station; the wheeled vehicle 3 is movably connected to the rails 2; the truck crane 5 is arranged beside the rails 2, and the hoist 4 is arranged on the truck crane 5, and the truck crane 5 and the hoist 4 are used to transfer the rocket from the wheeled vehicle 3 to the erection frame 6; the rails 2 are arranged in parallel with the erection frame 6. The erection frame 6 is docked with the launch platform 7, and the erection frame 6 is used to erect the rocket onto the launch platform 7, and the erection frame 6 is used to erect the rocket body, and the launch platform 7 is used to vertically support the rocket body after erection. The factory building 1 of the present application is built adjacent to the launch station, and the entire arrow is transported in a horizontal state using the wheeled vehicle 3, and no special transfer transport vehicle is required. The erection frame 6 is pre-jointed and debugged with the launch platform 7, and the vehicle-mounted crane 5 is used to transfer the rocket to the erection frame 6, without the need to carry the rocket to the launch platform 7. The present application provides an equipment layout of a three-level mode test and launch system for a large-scale carrier rocket, which is convenient for transporting rockets and reduces construction costs.

[0035] As a specific embodiment of the present invention, a three-level mode test and launch system for a large launch vehicle in the present application can be used not only for large launch vehicles, but also for medium-sized launch vehicles. The effect of using it for large launch vehicles is more obvious, and the transportation of the entire rocket is more convenient than the transportation methods in the prior art, thereby reducing transportation costs.

[0036] As a specific embodiment of the present invention, the rail 2 is laid in the factory building 1, extending from the factory building gate to the launch station, parallel to the erection frame 2, and the rail 2 is a temporary rail. Under the premise of meeting the safety distance between the rocket body and the erection frame 6, the rail 2 is as close to the erection frame 6 as possible to facilitate the transfer by the truck crane 5. There are several iron wheel frame vehicles 3, which are placed on the rail 2 and can be pushed along the rail 2. When the sub-stages of the rocket body are unloaded, the iron wheel frame vehicle 3 is pushed out of the factory building, and the truck crane 5 is used to transfer each sub-stage from the road transport vehicle to the iron wheel frame vehicle 3. Each sub-stage is pushed into the factory building 1 to carry out assembly and testing. After the whole arrow test is completed, the iron wheel frame vehicle 3 pushes the arrow body out of the factory building 1 along the rail 2, and the rocket and the erection frame 6 are placed side by side. The sling 4 and the truck crane 5 are used to transfer the arrow body, and transfer the arrow body from the iron wheel frame vehicle 3 to the erection frame 6. The launching platform 7 is located above the diversion groove and is fixedly connected to the diversion groove ground using a steel plate and a ground anchor. The erection frame 6 is pre-assembled on the launching station and docked with the launching platform 7.

[0037] As a specific embodiment of the present invention, the factory building 1 is located outside the explosion radius of the rocket launch, and is about 500m to 1000m away from the launch point. Here, the distance between the factory building 1 and the launch point is about 500m to 1000m, which is the preferred range, and can also be other ranges. The distance between the factory building 1 and the launch point is not limited here.

[0038] As a specific embodiment of the present invention, the plant 1 is a movable plant. This application uses a simple movable plant to replace a fixed technical plant to meet the needs of arrow body testing and reduce the cost of plant construction. The plant 1 is placed near the launch station, and there is no need to modify the transfer transportation road, which reduces the transportation cost of the entire arrow.

[0039] As another embodiment of the present invention, the factory building 1 is provided with a walking function and can be transformed into a movable factory building. When the net height of the factory building 1 is greater than the arrow-carrying height of the erection frame 6, it can be used for temporary protection of the entire rocket after the rocket is transferred to the erection frame 6.

[0040] As another specific embodiment of the present invention, the factory building 1 cancels the walking function to improve the sealing performance. Compared with the mobile factory building, the factory building 1 cancels the walking part and cannot be walked on the ground floor at will, which further reduces the construction cost of the factory building. The factory building 1 is fixed with ground anchors and ropes to enhance the wind resistance.

[0041] As a specific embodiment of the present invention, rocket sub-stage docking, instrument installation and testing work are carried out in the factory building 1, and the unloading of each sub-stage and the transfer of the entire rocket are all carried out outside the factory building 1. There is no need for matching medium or large truss cranes, only matching light gantry cranes. No large truss cranes are installed in the factory building 1, only light and movable gantry cranes are used, which further reduces the cost of factory building construction.

[0042] like Figure 4As shown, only one pair of temporary rails 2 need to be laid in the factory building 1. Compared with two to three pairs of rails set in a fixed technical factory building, the span of the factory building 1 is reduced, further reducing the cost of factory building construction.

[0043] As a specific embodiment of the present invention, a pair of rails 2 are laid in the plant 1, and the iron wheel carriage 3 can be pushed along the rails 2. The doors at both ends can be opened automatically for easy entry and exit. The plant 1 has windproof, dustproof, rainproof and snowproof functions, and has its own air conditioning system to provide environmental protection for the rocket. It adopts AC power supply to provide electricity for rocket testing. A lighting system is installed to provide appropriate lighting for the plant 1.

[0044] As a specific embodiment of the present invention, an iron wheel carriage 3 is used to complete the transfer of the whole arrow from the factory building 1 to the launching station, without the need to use a general or special whole arrow transportation vehicle, further reducing the whole arrow transportation cost.

[0045] As a specific embodiment of the present invention, a truck-mounted crane 5 is used to complete the unloading of each sub-stage arrow body and the reloading of the entire arrow without the need for a large truss crane, thereby further reducing costs.

[0046] As a specific embodiment of the present invention, the factory building 1 and the gantry crane installed in the factory building 1 can be disassembled, and the rails can be disassembled after use and transported to other launch stations, which can adapt to multi-station launch. The erection frame 6 and the launch platform 7 are disassembled after the launch mission is completed and can be transported to other launch stations for multiple uses.

[0047] like Figure 2 As shown, the rail 2 includes a first rail and a second rail; the first rail and the second rail are arranged in parallel, and a connecting rod 24 is fixedly connected between the first rail and the second rail; the first rail and the second rail both include a rail bottom 21, a rail head 22 and a rail waist 23; the rail bottom 21 and the rail head 22 are connected through the rail waist 23. A circular through hole is opened in the middle of the rail waist 23; the two ends of the connecting rod 24 pass through the circular through hole of the rail waist 23 of the first rail and the circular through hole of the rail waist 23 of the second rail respectively, and nuts are threadedly connected to the two ends of the connecting rod 24.

[0048] like Figure 2 , 3As shown, the rail bottom 21 is directly laid on the ground of the field, and the rail head 22 carries the iron wheel 31 of the iron wheel frame vehicle 3. The two tracks (the first track and the second track) are used in pairs, and a circular through hole is opened in the middle of the rail waist 23, which is connected by a connecting rod 24 to maintain the track gauge. The commonly used track gauge is the 1435mm standard track gauge, and the track gauge is not limited to 1435mm here. It can also be a track gauge in other ranges, and a wide gauge or a narrow gauge can also be used. The rail 2 is laid from the factory building 1 to a position side by side with the erection frame 6. The distance between the center line of the rail 2 and the center line of the erection frame 6 is "rocket body radius + half width of the erection frame + safety gap", where the safety gap is between 500mm and 1000mm. The rail 2 is a temporary rail, which can be disassembled after use and transported to other launch stations for use.

[0049] like Figure 3 As shown, the connecting rod 24 includes a rod body 241, a screw rod 242, and a nut 243. The two ends of the rod body 241 are screw rods 242, which pass through the through hole of the rail waist 23 and are fastened by nuts 243. The length of the rod body 241 is determined according to the required track gauge. The rod body 241 has a boss structure, and the boss structure of the rod body 241 abuts against the rail waist 23 to keep the track gauge at a set value.

[0050] like Figure 5 As shown, the iron wheel carriage 3 includes a frame 33, a bracket 32 ​​and an iron wheel 31. The bracket 32 ​​is arranged at the top of the frame 33, and the bracket 32 ​​is used to place the rocket; the iron wheel 31 is arranged at the bottom of the frame 33, and the iron wheel 31 is slidably connected to the rail 2, and the contact surface between the iron wheel 31 and the rail head 22 is a conical surface. The iron wheel 31 is a walking part, and the contact surface between the iron wheel 31 and the rail head 22 is a conical surface, which can be pushed along the rail 2, has a self-guiding function, and will not derail. The bracket 32 ​​is arc-shaped, matching the shape of the arrow body, and is used to place the rocket. The frame 33 usually has a lifting, lateral movement, and rolling mechanism to adjust the rocket posture, so as to facilitate the docking of each sub-stage into a whole arrow.

[0051] As a preferred embodiment of the present invention, the iron wheel frame vehicle 3 includes a plurality of iron wheel frame vehicles 3; the plurality of iron wheel frame vehicles 3 are spaced apart and arranged on the rails 2, and are used to transfer rockets. The present application uses a plurality of iron wheel frame vehicles 3 to jointly support the rocket. When the sub-stages of the rocket body are unloaded, the iron wheel frame vehicle 3 is pushed out of the factory building, and the vehicle-mounted crane 5 is used to transfer the sub-stages from the road transport vehicle to the iron wheel frame vehicle 3, and then push them into the factory building 1. In the factory building 1, the iron wheel frame vehicle 3 is used to horizontally park the sub-stages of the rocket, and the sub-stages are docked to form a complete arrow, and the final assembly and testing work is carried out on the iron wheel frame vehicle 3. After the rocket test is completed, the iron wheel frame vehicle 3 pushes the rocket out of the factory building 1 along the rails 2, and the rocket body and the erection frame 6 are placed side by side.

[0052] As a specific embodiment of the present invention, the sling 4 and the truck crane 5 are used for transferring the rocket body. In the state of transferring the rocket body, the iron wheel frame 3 is parked in parallel with the erection frame 6, the sling 4 is connected to the rocket body, and the truck crane 5 is used in cooperation with the sling 4 to transfer the rocket body from the iron wheel frame 3 to the erection frame 6. Since the length of the rocket body is relatively long, two truck cranes are used to complete the transfer work. After the transfer of the entire rocket is completed, the sling 4 is withdrawn and the truck crane 5 drives away from the launch site.

[0053] As a specific embodiment of the present invention, a guide groove is excavated directly below the launch pad 7, and the launch pad 7 is located above the guide groove opening; after the rocket is ignited, the gas flow generated by the tail flame of the rocket engine is discharged through the guide groove.
