DETAILED DESCRIPTION

[0020] The embodiments of the present application are described below in conjunction with the drawings in the present application. It should be understood that the implementation methods described below in conjunction with the drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application and do not constitute a limitation on the technical solutions of the embodiments of the present application.

[0021] Those skilled in the art will appreciate that, unless expressly stated, the "said" and "the" used herein may also include plural forms. It should be further understood that the term "including" used in the specification of the present application refers to the presence of the features, integers, elements and / or components, but does not exclude the implementation of other features, information, data, operations, elements, components and / or combinations thereof supported by the technical field. The term "and / or" used herein refers to at least one of the items defined by the term, for example, "A and / or B" may be implemented as "A", or as "B", or as "A and B".

[0022] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0023] First, several terms involved in this application are introduced and explained: Technical area: A special area where the rocket completes technical preparations before launch. The rocket's final assembly, testing, partial filling, etc. are usually completed in the technical area.

[0024] Launch area: A dedicated area with launch facilities and launch functions.

[0025] At present, the rocket test and launch modes mainly include the two-vertical mode of vertical assembly and vertical testing, the three-vertical mode of vertical assembly, vertical transfer, and vertical testing, and the three-horizontal mode of horizontal assembly, horizontal transfer, and horizontal testing. Among them, the two-vertical mode must be equipped with a fully functional service tower, and the rocket's testing, assembly, maintenance and other work are all carried out through the service tower; the three-vertical mode is equipped with a fully functional vertical assembly plant, and the rocket completes assembly, testing and other work in the vertical assembly plant. The launch station can be equipped with a fully functional service tower or a simplified service tower; the three-horizontal mode usually uses a transfer launch vehicle to realize the transfer of the rocket between the technical area and the launch area and the conversion between the horizontal and vertical states, and docking with the launch station in the launch area. In order to achieve high-density launches and system simplification, and at the same time to control the overall construction cost and operating cost of the launch site, commercial launch vehicles usually use the three-horizontal mode as the first choice for rocket test and launch modes.

[0026] However, the launch conditions at launch sites in different regions may be different, and the launch preparation system is not universal, which makes it difficult for the same launch preparation equipment to adapt to various launch sites to complete launch preparation work.

[0027] If each launch position is equipped with its own dedicated launch preparation equipment, it will be necessary to develop different launch plans and build different launch preparation equipment, which will lead to higher launch costs and make it difficult to share related maintenance and care resources, which is not conducive to sustainable development.

[0028] The launch preparation equipment and launch preparation system for a carrier rocket provided in this application are intended to solve the above technical problems of related technologies.

[0029] The following is a detailed description of the technical solution of the present application and how the technical solution of the present application solves the above technical problems with specific embodiments. It should be noted that the following implementations can refer to, draw on or combine with each other, and the same terms, similar features and similar implementation steps in different implementations will not be described repeatedly.

[0031] The launch preparation device 100 includes a basic configuration and a simplified configuration.

[0032] Please refer to Figure 1 , Figure 2 , Fig.10 and Fig.11 When the launch preparation equipment 100 adopts the basic configuration, it includes a transfer platform system 110, a chassis assembly 120, a erection frame 130 and a hydraulic system 140, which are used to cooperate with the first launch station 200 to form a launch preparation system for the carrier rocket 300; the chassis assembly 120 is arranged on the transfer platform system 110, the erection frame 130 is arranged on the chassis assembly 120, and the hydraulic system 140 is connected between the chassis assembly 120 and the erection frame 130; the first launch station 200 includes a fixed launch platform 210, and a movable launch platform 150 is configured on the fixed launch platform 210, and the movable launch platform 150 is used to dock with the carrier rocket 300 in the prepared state.

[0033] Please refer to Figure 3 and Fig.12 When the launch preparation equipment 100 adopts a simplified configuration, it includes a transfer platform system 110, an erection frame 130 and a movable launch platform 150, which are used to cooperate with the second launch station 200 to form a launch preparation system for the carrier rocket 300; the erection frame 130 and the tail end of the carrier rocket 300 supported by it are both docked with the movable launch platform 150; the second launch station 200 includes a fixed launch platform 210 and an erection cylinder 220, the movable launch platform 150 is used to dock with the fixed launch platform 210, and the erection cylinder 220 is used to connect with the erection frame 130.

[0034] In this embodiment, the launch preparation device 100 can be assembled into a basic configuration and a simplified configuration, respectively adapted to the first launch station 200 and the second launch station 200, and can be flexibly combined with the launch station 200 according to different conditions to complete the launch preparation work, which can greatly reduce the high launch cost caused by the non-universal or low degree of universalization of the launch preparation system. Moreover, the maintenance and maintenance resources of each structure in the launch preparation device 100 can be shared, which is conducive to sustainable development.

[0035] Specifically, when the launch preparation equipment 100 adopts the basic configuration, the transfer platform system 110, the chassis assembly 120, the erection frame 130 and the hydraulic system 140 are assembled into the launch preparation equipment 100 (such as a transfer launch vehicle), which is transported to the launch area after loading the rocket in the technical area, and after arriving at the launch position, the erection frame 130 is erected from the horizontal state to the preparation state through the hydraulic system 140, thereby driving the carrier rocket 300 to stand upright and dock with the movable launch platform 150 configured on the fixed launch platform 210 of the first launch station 200. It can be understood that the preparation state of the carrier rocket can include a vertical state.

[0036] When the launch preparation equipment 100 adopts a simplified configuration, the transfer platform system 110, the erection frame 130 and the movable launch platform 150 are assembled into the launch preparation equipment 100 (such as a transfer launch vehicle), which is transported to the launch area after loading the rocket in the technical area. The movable launch platform 150 is a part of the launch preparation equipment 100 and has been docked with the carrier rocket 300 in the technical area. After arriving at the launch position, the erection frame 130 is erected from a horizontal state to a preparation state through the erection cylinder 220 of the second launch station 200, thereby driving the carrier rocket 300 to be erected, and the movable launch platform 150 at the tail end of the rocket is docked with the fixed launch platform 210 of the second launch station 200.

[0037] It can be understood that the movable launch platform 150 in the first launch station 200 and the movable launch platform 150 in the simplified configuration launch preparation equipment 100 can be the same movable launch platform 150, which can be used as a separate device to form the first launch station 200 with the fixed launch platform 210, or can be used as a part of the launch preparation equipment 100, and can complete the docking with the carrier rocket 300 before transportation, reflecting the flexibility of the launch preparation system of the carrier rocket 300 provided in the embodiment of the present application.

[0038] For some possible embodiments, please refer to Figure 4 The erecting frame 130 includes: a body 131 , a plurality of supporting structures 132 axially arranged at one side of the body 131 , and a locking structure 133 arranged at the tail of one side of the body 131 .

[0039] The supporting structure 132 is used to support the launch vehicle 300 , and the locking structure 133 is used to lock the tail 301 of the launch vehicle 300 .

[0040] In this embodiment, the same erection frame 130 can be used in the two configurations of the launch preparation equipment 100. The main body 131 of the erection frame 130 plays a major bearing role. The multiple support structures 132 are connected to the body of the launch vehicle 300 at different positions to play a multi-point support role. The locking structure 133 fixes and locks the body of the launch vehicle 300 at the tail end to ensure a relatively fixed state between the body of the launch vehicle 300 and the erection frame 130.

[0041] Optionally, when the launch preparation device 100 adopts the basic configuration, the locking structure 133 is a rocket body locking structure 133, which is locked with the tail end of the rocket body to limit the tail end of the rocket body.

[0042] Optionally, when the launch preparation device 100 adopts a simplified configuration, the locking structure 133 is a locking structure 133 of a movable launch platform 150, and the movable launch platform 150 docked with the tail end of the rocket body is locked. The axial limit of the rocket body is achieved by the movable launch platform 150, and there is no need to set up a locking structure 133 to limit the tail 301 of the rocket body.

[0043] For some possible embodiments, please refer to Figure 4 The erection frame 130 also includes: a fairing operating platform 134, a second-stage upper operating platform 135, a second-stage lower operating platform 136 and a first-stage operating platform 137, which are arranged on one side of the main body 131 along the axial direction close to the tail end of the main body 131 in sequence, and correspond to the positions of the fairing, the second-stage upper part, the second-stage lower part and the first-stage rocket of the carrier rocket 300 respectively.

[0044] In this embodiment, each operating platform such as the fairing operating platform 134, the second-stage upper operating platform 135, the second-stage lower operating platform 136 and the first-stage operating platform 137 are integrated on the erection frame 130. After the erection frame 130 drives the carrier rocket 300 to erect, the operator can provide corresponding services to the corresponding positions of the rocket body through each operating platform on the erection frame 130, including but not limited to manual plugging and unplugging of connectors, automatic plugging and unplugging of connectors, connector separation, connector storage, rocket body maintenance, repair and replacement of equipment inside the rocket, emergency rescue, etc. This embodiment can be compatible with the service tower function, reduce the construction of the service tower of the launch station 200, and can be compatible with the launch station 200 with poor infrastructure conditions, saving costs.

[0045] It should be noted that the positions of the fairing, the upper part of the second-stage rocket, the lower part of the second-stage rocket and the first-stage rocket of the launch vehicle 300 are similar to those in the related art and will not be repeated here.

[0046] Please refer to Figure 5 , Figure 5 The schematic structural diagram of the tail end of a launch preparation frame 130 in an embodiment of the present application shows that a locking structure 133 overlaps laterally with at least one supporting structure 132 .

[0047] In some possible embodiments, the erecting frame 130 further includes: a main trunnion seat 138 of the erecting frame 130 disposed on the other side of the body 131 along the rear end of the body 131 .

[0048] When the launch preparation apparatus 100 is in the base configuration, the main trunnion mount 138 of the erector frame 130 is coupled to the chassis assembly 120 .

[0049] In this embodiment, please refer to Figure 1 and Figure 7 , Figure 7 A partial enlarged view of the connection between the erection frame and the chassis assembly in a launch preparation device provided in an embodiment of the present application. When the launch preparation device 100 adopts the basic configuration, the main trunnion seat 138 of the erection frame 130 is connected to the main trunnion seat 122 of the chassis assembly 120 and fixed to the chassis assembly 120.

[0050] Optionally, refer to Figure 6 , Figure 6 A partial enlarged view of the connection between the erection frame and the chassis assembly through a hydraulic system in a launch preparation device provided in an embodiment of the present application. One end of the hydraulic system 140 is connected to the erection ear shaft seat 121 of the chassis assembly 120 on the left main beam and the right main beam of the chassis assembly 120, and the other end is connected to the side ear shaft seat 139 of the erection frame 130. The erection of the erection frame 130 can be completed through the hydraulic system 140.

[0051] In some possible embodiments, the transfer platform system 110 includes: a front vehicle 111 and a rear vehicle 112 that are spaced apart along the axial direction.

[0052] When the launch preparation device 100 adopts the basic configuration, the front vehicle 111 and the rear vehicle 112 are longitudinally coaxially arranged to jointly support the chassis assembly 120 .

[0053] The longitudinal direction is the axial direction of the vertical frame 130 in the horizontal state.

[0054] In this embodiment, the transfer platform system 110 includes a front vehicle 111 and a rear vehicle 112, wherein the front vehicle 111 is a transport vehicle close to the head of the launch vehicle 300, and the rear vehicle 112 is a transport vehicle close to the tail 301 of the launch vehicle 300. When the launch preparation device 100 adopts the basic configuration, the front vehicle 111 and the rear vehicle 112 are arranged axially at intervals, and jointly carry the chassis assembly 120, and the chassis assembly 120 carries the erection frame 130.

[0055] In this embodiment, the transfer platform system 110 has the same structure as the front vehicle 111 and the rear vehicle 112 in the two configurations, but is arranged in different ways, and can be flexibly applied to different launch preparation systems, with high versatility.

[0056] For some possible embodiments, please refer to Fig. 9 When the launch preparation device 100 adopts a simplified configuration, the main trunnion seat 138 of the erection frame 130 is used to connect with the fixed launch platform 210 of the second launch station 200 (such as the main trunnion seat 214 of the fixed launch platform 210).

[0057] In this embodiment, when the launch preparation device 100 adopts a simplified configuration, the main trunnion seat 138 of the erection frame 130 is connected to the main trunnion seat 214 of the fixed launch platform 210 and is fixed to the fixed launch platform 210 .

[0058] In some possible embodiments, when the launch preparation equipment 100 adopts a simplified configuration, the front vehicle 111 of the transfer platform system 110 is arranged longitudinally, and the rear vehicle 112 of the transfer platform system 110 is arranged transversely, and they jointly support the erection frame 130 ; the rear vehicle 112 supports the tail of the erection frame 130 .

[0059] The horizontal direction is perpendicular to the vertical direction in a horizontal state.

[0060] In this embodiment, when the launch preparation equipment 100 adopts a simplified configuration, the arrangement of the front vehicle 111 and the rear vehicle 112 of the transfer platform system 110 can be adjusted according to the shape of the launch vehicle 300, and there is no need to arrange the chassis assembly 120. Specifically, if the radial dimension of the head 302 of the launch vehicle 300 is smaller than the radial dimension of the tail 301, the front vehicle 111 is arranged longitudinally and the rear vehicle 112 is arranged transversely, so as to increase the supporting area of ​​the rear vehicle 112 for the tail 301 of the launch vehicle 300 as much as possible.

[0061] Based on the same inventive concept, an embodiment of the present application also provides a launch preparation system for a carrier rocket 300, including a launch station 200 and a launch preparation device 100 for any carrier rocket 300 provided in the aforementioned embodiments.
