Description

Technical Field

[0001] The present application relates to the technical field of launch pads, and more specifically, to a launch pad and a launch method for a carrier rocket. Background Art

[0002] Before launching a rocket, the launch pad needs to be fixed on the top of the foundation guide groove so that the guide port on the launch pad is connected to the guide groove, thereby guiding the high-temperature tail flame generated after the launch of the carrier rocket. At present, the thermal protection scheme of most launch pads is to install a heat shield on the inner wall of the guide port. Due to the erosion of the high-temperature tail flame, the life of the thermal protection coating on the heat shield is limited. Therefore, after the first or multiple launches of the carrier rocket, the thermal protection coating must be re-maintained.

[0003] However, due to the depth of the diversion trough, maintenance requires personnel to enter the diversion trough for high-altitude operations, which is difficult to operate and poses a safety risk of falling from a height. At the same time, because the heat-resistant plate is perpendicular to the ground, the heat-resistant coating is not easy to adhere when applied in a vertical state, resulting in the problem of repeated repairs. If the paint falls into the diversion trough, the diversion trough needs to be cleaned. Summary of the invention

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.

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, steps, operations, elements and / or components, but does not exclude the implementation of other features, information, data, steps, 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".

[0021] 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 with reference to the accompanying drawings.

[0022] In order to solve the technical problems in the related art that when maintaining the heat-resistant coating 220 on the heat-resistant coating plate 230 on the launch platform, the operation is difficult, or the heat-resistant coating 220 is not easy to adhere, and there are repeated repairs, refer to Figure 1-Figure 4 An embodiment of the present application provides a launch platform, including a launch platform body 100 provided with a through guide port 110, a first heat protection plate 200 arranged on the launch platform body 100, a second heat protection plate 400 and a driving structure 300.

[0023] The second heat protection plate 400 detachably covers the inner wall of the second side 112 of the air guide port 110 .

[0024] The first heat shield 200 is rotatably disposed on the inner side wall of the first side 111 of the air guide 110. The driving structure 300 is disposed at the bottom of the launch platform body 100, and is used to drive the first heat shield 200 to rotate to an unfolded state or a retracted state. When the first heat shield 200 is in the unfolded state, the first heat shield 200 is horizontally arranged at the top of the air guide 110.

[0025] When maintaining the first heat protection coating plate 230, the driving structure 300 can be used to rotate the first heat protection plate 200 to the unfolded state. The first heat protection plate 200 is arranged horizontally on the top of the guide port 110, so that the maintenance personnel can stand on the first heat protection plate 200 to apply the heat protection coating 220 on the first heat protection plate 200 or replace the heat protection coating plate 230, and change the vertical maintenance mode to the horizontal maintenance mode, which can reduce the difficulty of operation, improve maintenance efficiency, and shorten the maintenance cycle. Moreover, it avoids the safety risks of high-altitude operations and improves the safety and convenience during maintenance. Coating the heat protection coating 220 in a horizontal state is conducive to improving the adhesion and uniformity of the heat protection coating 220, thereby helping to improve the heat protection performance of the first heat protection plate 200.

[0026] Furthermore, a removable second heat shield 400 is designed on the second side 112 of the guide port 110. When the second heat shield 400 needs maintenance, the second heat shield 400 can be lifted out as a whole for replacement or maintenance, thereby avoiding high-altitude operations to maintain the thermal protection coating 220. This allows for faster maintenance and adapts to high-density launches of carrier rockets.

[0027] Optionally, the second heat shield 400 is hung on the inner side wall of the second side 112 of the air guide port 110. Alternatively, the second heat shield 400 is fixed to the inner side wall of the second side 112 of the air guide port 110 using bolts, or the second heat shield 400 is detachably mounted on the inner side wall of the second side 112 of the air guide port 110 using buckles. In the present application, there is no specific limitation on the detachable connection method of the second heat shield 400.

[0028] Optionally, refer to Figure 3 When the first heat protection plate 200 is in the retracted state, the first heat protection plate 200 extends vertically to cover the inner side wall of the first side 111 of the guide port 110 , and together with the second heat protection plate 400 , forms an insulation port 500 for insulating the guide port 110 .

[0029] When the first heat protection plate 200 is in a horizontally arranged unfolded state, it satisfies the maintenance personnel to step on and maintain the heat protection coating 220 of the first heat protection plate 200 in a non-high-altitude operation manner. When the first heat protection plate 200 is in a vertically extended retracted state, the first heat protection plate 200 and the second heat protection plate 400 jointly enclose a heat insulation port 500 for heat insulation (or heat protection) of the air guide port 110, so as to provide heat protection for the air guide port 110.

[0030] Optionally, refer to Figure 3 There are two first heat protection plates 200 and two second heat protection plates 400 , the two first heat protection plates 200 are respectively arranged on the first side 111 of the guide port 110 , and the two second heat protection plates 400 are respectively arranged on the second side 112 of the guide port 110 .

[0031] When the first heat protection plates 200 are in the unfolded state, the distal ends of the two first heat protection plates 200 are in contact or close to each other.

[0032] Optionally, the first side 111 of the guide port 110 is a long side along the length direction of the guide port 110, and the second side 112 of the guide port 110 is a short side along the direction of the guide port 110. The two first heat protection plates 200 are symmetrically arranged on the long side of the guide port 110. When the first heat protection plates 200 are in the unfolded state, the distal ends of the two first heat protection plates 200 are in contact or close to block the guide port 110 completely or partially, so that the maintenance personnel can step on the first heat protection plates 200 and stand on the first heat protection plates 200 to maintain the heat protection coating 220, thereby ensuring the personal safety of the maintenance personnel and effectively reducing the probability of the heat protection coating 220 liquid dripping in the guide groove when applying the heat protection coating 220.

[0033] Optionally, refer to Figure 5 The launch station body 100 includes an installation box 120 provided with an air guide port 110 , and the driving structure 300 is at least partially located inside the installation box 120 outside the first side 111 of the air guide port 110 .

[0034] The driving structure 300 includes an inclined telescopic member 310 , a first end of which is hinged to the bottom plate of the installation box 120 , and a second end of which passes through the side plate of the installation box 120 and is hinged to the second side surface of the first heat protection plate 200 .

[0035] When the first heat protection plate 200 needs to be maintained, the telescopic member 310 is controlled to gradually extend, driving the first heat protection plate 200 to gradually rotate from a vertically extended folded state and a tilted critical state to a horizontally arranged unfolded state. Since the first end of the telescopic member 310 is hinged to the bottom plate of the installation box 120, as the telescopic member 310 is gradually extended and as the first heat protection plate 200 is gradually rotated, the telescopic member 310 gradually rotates around the hinge axis with the bottom plate of the installation box 120, so that the angle between the telescopic member 310 and the bottom plate of the installation box 120 gradually decreases.

[0036] Optionally, refer to Figure 6 The telescopic member 310 and the first heat shield 200, as well as the telescopic member 310 and the bottom plate of the installation box 120 are hinged by hinges 240, the fixed portion of the telescopic member 310 is installed with a first hinge seat 310, and the telescopic portion of the telescopic member 310 is installed with a second hinge seat 330. The telescopic member 310 can use a driving structure 300 such as a cylinder, a hydraulic cylinder or an electric telescopic rod, which is not specifically limited in this application.

[0037] Optionally, refer to Figure 6 The first heat protection plate 200 includes a structural base plate 210 and a heat protection coating 220 coated on a first side surface of the structural base plate 210 .

[0038] When the first heat protection plate 200 is heat-insulated by coating the heat protection coating 220 on its surface, i.e., the first side surface away from the telescopic member 310, during maintenance, the maintenance personnel only need to stand on the first heat protection plate 200 to reapply the heat protection coating 220, thereby improving the use efficiency of the structural base plate 210 and extending the service life of the structural base plate 210.

[0039] Optionally, refer to Figure 6 The first heat protection plate 200 includes a structural base plate 210 and a heat protection coating plate 230 detachably disposed on a first side surface of the structural base plate 210 .

[0040] When the first heat protection plate 200 uses a removable heat protection coating plate 230 on the surface of the structural base plate 210, that is, the first side surface away from the telescopic member 310 for heat insulation, during maintenance, the maintenance personnel stand on the first heat protection plate 200, remove the heat protection coating plate 230 from the structural base plate 210, and replace it with a new heat protection coating plate 230, making the maintenance of the first heat protection plate 200 more convenient and efficient.

[0041] Optionally, the heat-resistant coating plate 230 can be bonded to the structural base plate 210, or connected to the structural base plate 210 using screws, or other installation methods that can detachably connect the heat-resistant coating plate 230 to the structural base plate 210 are not limited here.

[0042] Optionally, refer to Figure 7 The second heat protection plate 400 includes a supporting layer plate body 410 and a heat protection coating layer coated on one side of the plate body supporting layer or a heat protection layer plate body arranged on one side of the plate body supporting layer.

The cooling structure 600 includes a main pipe of the guide port 110 and at least two branch pipes of the guide port 110 arranged at intervals along the extension direction of the main pipe of the guide port 110. The main pipe of the guide port 110 extends upward and the end is bent toward the guide port 110.

[0044] By arranging a cooling structure 600 in the space inside the installation box 120 and connecting the main diversion pipe to an external water source circuit, the coolant passes through the main pipe of the diversion port 110 and at least two branch pipes of the diversion port 110 to spray water to cool the diversion port 110, thereby improving the thermal protection effect of the diversion port 110.

[0045] Optionally, two groups of main pipes of the guide port 110 and branch pipes of the guide port 110 are symmetrically arranged on the first side 111 of the guide port 110 , thereby further improving the heat protection effect of the guide port 110 and ensuring comprehensive cooling of the guide port 110 .

[0046] Optionally, refer to Figure 8 and Fig.10 The cooling structure 600 of the embodiment of the present application further includes an upper table main pipe 630 and at least two upper table branch pipes 640 , and a through hole 130 communicating with the upper table branch pipes 640 is opened on the top plate of the launch platform body 100 .

[0047] The upper table main pipeline 630 is connected to the external coolant circuit. The coolant flows into the through hole 130 on the top plate of the launch platform body 100 through the upper table main pipeline 630 and at least two upper table branch pipelines 640, thereby cooling down other parts of the launch platform body 100 located around the guide port 110, thereby improving the thermal protection effect of the launch platform body 100.

[0048] Optionally, two groups of upper table main pipes 630 and upper table branch pipes 640 are also symmetrically arranged on the first side 111 of the guide port 110, and the upper table main pipes 630 are arranged on the side of the guide port 110 main pipe away from the guide port 110, so as to facilitate cooling of the periphery of the guide port 110 and improve the overall cooling effect of the launch platform body 100.

[0049] The present application also provides a method for launching a carrier rocket based on the above-mentioned launch platform, referring to Fig.11 , including steps S101-S102.

[0050] S101: Before the launch of the carrier rocket, the driving structure 300 is used to drive the first heat protection plate 200 to rotate to a horizontal unfolded state, and the second heat protection plate 400 is detachably arranged on the inner wall of the guide port 110 .

[0051] The launch platform includes a launch platform body 100 provided with an air guide port 110 , a first heat protection plate 200 , a driving structure 300 and a second heat protection plate 400 .

[0052] S102: After the launch vehicle is launched, the driving structure 300 is used to drive the first heat shield 200 to rotate again to a horizontal unfolded state, so that maintenance personnel can stand on the first heat shield 200 for maintenance, release the detachable connection between the second heat shield 400 and the launch platform body, and lift the second heat shield 400 out of the guide port 110 for maintenance or replacement.

[0053] Optionally, refer to Figure 5, after the driving structure 300 is used to drive the first heat protection plate 200 to rotate to a horizontal unfolded state, the second heat protection plate 400 is detachably arranged on the inner side wall of the air guide port 110, and before the driving structure 300 is used to drive the first heat protection plate 200 to rotate again to a horizontal unfolded state, it also includes: The carrier rocket is dropped onto the launch pad body 100 , and the first heat shield 200 in a horizontally unfolded state is used for operators to stand on the first heat shield 200 to perform operations.

[0054] The driving structure 300 is used to drive the first heat protection plate 200 to rotate to a vertically extended stowed state.

[0055] The carrier rocket is launched with the first heat shield 200 in the retracted state.

[0056] Before the launch of the carrier rocket, the first heat shield 200 is rotated to a horizontally unfolded state, providing a standing space for the operator, so that the operator can install and arrange the carrier rocket on the launch pad body 100 and adjust the launch angle of the carrier rocket. Before the launch of the carrier rocket, the first heat shield 200 is rotated to a vertically extended stowed state, exposing the heat insulation opening 500 formed by the first heat shield 200 and the second heat shield 400, so that the wake generated after the launch of the carrier rocket can be introduced into the heat insulation opening 500, and the first heat shield 200 and the second heat shield 400 can be used to provide thermal protection for the guide port 110.

[0057] Optionally, refer to Figure 8-Figure 10 , when the first heat shield 200 is in the stowed state and the carrier rocket is launched, the present invention also includes: The external coolant circuits of the main pipeline of the guide port 110 and the upper platform main pipeline 630 are connected, so that the branch pipeline of the guide port 110 cools the guide port 110, and the upper platform branch pipeline 640 cools the top plate of the launch platform body.

[0059] The branch pipe of the guide port 110 sprays coolant to cool the guide port 110, so as to quickly take away the heat of the wake generated by the launch vehicle and concentrated at the guide port 110 after launch, and cooperates with the first heat shield 200 and the second heat shield 400 to improve the thermal protection effect of the guide port 110. The upper platform branch pipe 640 sprays coolant to cool the part of the launch platform body 100 located at the periphery of the guide port 110, taking away the heat transferred from the guide port 110 to the launch platform body 100, thereby improving the thermal protection effect of the launch platform body 100 as a whole.

[0060] The beneficial technical effects brought about by the technical solution provided in the embodiment of the present application include: when maintaining the first heat protection coating plate 230, the driving structure 300 can be used to rotate the first heat protection plate 200 to the unfolded state, and the first heat protection plate 200 is horizontally arranged on the top of the guide port 110, so that the maintenance personnel can stand on the first heat protection plate 200 to coat the heat protection coating 220 on the first heat protection plate 200 or replace the heat protection coating plate 230. This maintenance mode is changed from a vertical operation mode to a horizontal operation mode, which reduces the operation difficulty, improves the maintenance efficiency, shortens the maintenance cycle, avoids the safety risks of high-altitude operations, and improves the safety and convenience during maintenance; coating the heat protection coating 220 in a horizontal state is more conducive to the adhesion and uniform distribution of the heat protection coating 220, which is beneficial to improving the heat protection performance of the first heat protection plate 200.

[0061] A detachable second heat shield 400 is designed on the second side 112 of the guide port 110. When the second heat shield 400 needs maintenance, the second heat shield 400 can be hoisted out as a whole for replacement or maintenance, avoiding high-altitude operations to maintain the heat shield coating 220. Maintenance is faster and adapts to the high-density launch of carrier rockets.

[0062] By arranging a cooling structure 600 in the space inside the installation box 120, the coolant passes through the main pipe of the guide port 110 and at least two branch pipes of the guide port 110 to cool down the guide port 110. At the same time, the coolant passes through the upper table main pipe 630 and the upper table branch pipe 640 to cool down the top plate of the launch platform body 100, thereby improving the thermal protection effect of the guide port 110 and other parts of the launch platform body 100.

[0063] A detachable second heat protection plate 400 is designed on the second side 112 of the air guide port 110 . When the second heat protection plate 400 needs maintenance, the second heat protection plate 400 can be hoisted out as a whole for replacement or maintenance, thus avoiding high-altitude operations to maintain the heat protection coating 220 .
