Abstract
Description
Technical Field
[0001] This application relates to the technical field of aircraft protection, and in particular to a modular, quick-closing, openable launch pad aircraft protection device. Background Technology
[0002] Liquid rocket-powered aircraft that adopts a vertical takeoff and launch method need to operate in an upright state at the launch pad for several days during the launch preparation phase. During this period, they will experience harsh natural environmental conditions such as strong winds, strong sunlight, and rainfall. The ground launch support system must design a special protective device scheme for the aircraft system.
[0003] Rocket missions employing a "three-vertical" or "two-horizontal-two-vertical" launch pattern require the construction of a fixed service tower at the launch site. This tower houses a rotating, folding / opening protective device to address rocket protection during the launch preparation phase. However, for spacecraft using a "three-horizontal" launch pattern, a fixed service tower is typically not constructed at the launch site. Therefore, it's not possible to provide a rotating, folding / opening protective device like those used for traditional rockets. This is particularly problematic for new reusable, lift-type winged spacecraft, where sudden gusts of wind could cause instability and tipping while the spacecraft is upright, leading to launch failure. Therefore, the ability to rapidly deploy protective devices is crucial. Summary of the Invention
[0004] The technical problem solved by this invention is to overcome the shortcomings of the prior art and provide a modular, quick-closing, and openable launch pad aircraft protection device. It can achieve rapid hoisting and positioning, and after installation, the modules can be quickly fixed together to form an integrated protection device. It is easy to close and open quickly, and meets the needs of launch pad aircraft protection.
[0005] The technical solution of this invention is:
[0006] A modular, quick-closing, openable launch pad aircraft protection device includes multiple connecting layers arranged vertically in sequence, and a top layer located on top of the connecting layers. The top layer is used to close the top of the connecting layers. Each connecting layer includes a left connecting layer and a right connecting layer, and the top layer includes a left top layer and a right top layer.
[0007] Positioning devices for positioning are provided between two adjacent left connecting layers, between the left connecting layer and the top left layer, between two adjacent right connecting layers, and between the right connecting layer and the top right layer.
[0008] The left and right connecting layers, two adjacent left connecting layers, the left connecting layer and the top left layer, two adjacent right connecting layers, and the right connecting layer and the top right layer are all connected by locking devices.
[0009] The positioning device includes two opposing limiting plates, the distance between the two limiting plates gradually increases upwards, and the two limiting plates are located on the inner and outer sides of the top of the left connecting layer and / or the right connecting layer, so that the bottom of the upper left connecting layer and / or the right connecting layer is locked between the two limiting plates.
[0010] The two opposing limiting plates are connected to a vertical rib plate on their opposite sides.
[0011] The locking device includes a positioning seat and a locking bolt. The positioning seat and the locking bolt are respectively connected to two different parts that are locked by the locking device. The locking bolt is rotatably connected to the part connected to itself, and the positioning seat is fixedly connected to the part connected to itself. The positioning seat has a groove for the locking bolt to be inserted into. The locking bolt is threaded with a locking nut, which is engaged at one end of the groove.
[0012] The connecting layer is provided with a wave-transparent window.
[0013] The left connecting layer, right connecting layer, left top layer, and right top layer all include a frame and louvered ventilation baffles.
[0014] The bottommost connecting layer frame is provided with a quick-release baffle for quick disassembly. After the quick-release baffle is removed, it forms a tail flame guide channel.
[0015] The quick-release baffle of the bottom connecting layer is a common flexible curtain structure. The flexible curtain has hook and loop fasteners around its perimeter, and there are also hook and loop fasteners at corresponding positions on the frame of the bottom connecting layer. The flexible curtain and the frame are connected by hook and loop fasteners, and can be quickly disassembled by pulling before ignition and firing.
[0016] The bottommost connecting layer is connected to the ground by anchor bolts.
[0017] The left connecting layer, right connecting layer, left top layer, and right top layer of the multi-layer are all independent structural modules. Each of the left connecting layer, right connecting layer, left top layer, and right top layer is connected to a lifting point for lifting. Each of them can independently bear the force and can be independently lifted by a truck crane. After the aircraft is in place, it can be quickly assembled in sections. The top layer can be quickly opened before launch ignition and can be quickly disassembled in sections after the launch mission is completed.
[0018] In summary, this application includes at least the following beneficial technical effects:
[0019] (1) The aircraft that meets the vertical take-off and launch method must be protected against the natural environment (strong winds, strong sunlight, and rainfall) in the vertical state at the launch pad.
[0020] (2) It can achieve rapid closing and rapid opening functions to meet the pre-launch workflow of flight test.
[0021] (3) The plan is economical and efficient, avoiding the construction of new large-scale fixed launch service towers and other ground facilities. Attached Figure Description

[0030] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments:
[0031] This application discloses a modular, quick-closing, openable launch pad aircraft protection device, such as... Figure 1 a, Figure 1 b and Figure 2 As shown, the system includes multiple vertically arranged connecting layers and a top layer located on top of the connecting layers, which is used to seal the top of the connecting layers. The connecting layers are cylindrical with openings at both ends, and multiple connecting layers are connected sequentially to form protective spaces with different internal heights. In this embodiment, the connecting layers are rectangular cylinders. Each connecting layer includes a left connecting layer 11 and a right connecting layer 21, and the top layer includes a left top layer 12 and a right top layer 22. Positioning devices are provided between two adjacent left connecting layers 11, between a left connecting layer 11 and a left top layer 12, between two adjacent right connecting layers 21, and between a right connecting layer 21 and a right top layer 22. Locking devices are used to connect the left connecting layers 11 and 21, between two adjacent left connecting layers 11, between a left connecting layer 11 and a left top layer 12, between two adjacent right connecting layers 21, and between a right connecting layer 21 and a right top layer 22.
[0032] During the aircraft's erection process, the modular, quick-release launch pad protection device is closed. Before launch, a truck crane is used to open the top left and right modules to clear the takeoff area and open the first-layer baffle to form a tail flame guide channel.
[0033] In this embodiment, the application scenario connection layer consists of 4 layers, totaling 8 basic modules. Each module comprises a load-bearing frame and a louvered ventilation baffle structure. The louvered ventilation baffle is fixedly connected to the frame. The application of the louvered ventilation baffle reduces the wind load on the protective device, while also enabling the protective device to withstand wind-resistant functions, allowing the aircraft to withstand level 8 ground winds while erected at the launch position; it also provides rain protection, allowing the aircraft to withstand moderate rain while erected at the launch position; and it provides sand and dust protection, allowing the aircraft to withstand sandstorms while erected at the launch position. The connection layer is equipped with a wave-transparent window 5, which can meet the ground testing requirements of the on-board antenna.
[0034] like Figure 3 As shown, the locking / unlocking method is as follows: the left connecting layer 11 and the right connecting layer 21 of the first layer are locked to the ground using anchor bolts. Multiple sets of "quick-locking mechanisms" are used between the upper modules for rapid locking / unlocking. Specifically, the locking device includes a positioning seat 41 and locking bolts 42. The locking bolts 42 are connected to two different parts locked by the locking device. The locking bolts 42 are rotatably connected to their respective connecting parts, while the positioning seat 41 is fixedly connected to its connecting parts. The positioning seat 41 has a groove for the locking bolts 42 to engage. A locking nut 43 is threaded onto the locking bolts 42 and engages at one end of the groove. After each module is installed in place, rapid fixing between modules can be achieved.
[0035] like Figure 3 As shown, the design incorporates a V-shaped opening guide positioning plate structure for rapid docking and positioning of each module after lifting. Specifically, the positioning device includes two opposing limiting plates 31, with the distance between them gradually increasing upwards. The two limiting plates 31 are located on the inner and outer sides of the top of the left connecting layer 11 and / or the right connecting layer 21, respectively, to secure the bottom of the upper-layer left connecting layer 11 and / or right connecting layer 21 between the two limiting plates 31. Vertical stiffening plates 32, perpendicular to the limiting plates 31, are connected to the opposite sides of the two opposing limiting plates 31. This allows for rapid lifting and positioning between adjacent left connecting layers 11 or right connecting layers 21.
[0036] The frame of the bottom connecting layer is equipped with a quick-release baffle 61. After the quick-release baffle 61 is removed, it forms a tail flame guide channel. The quick-release baffle 61 of the bottom connecting layer is a common flexible curtain structure. The flexible curtain has hook and loop fasteners around its perimeter, and there are also corresponding hook and loop fasteners on the frame. The flexible curtain and the frame are connected by hook and loop fasteners, and it can be quickly removed by pulling before ignition and firing.
[0037] The implementation principle of this application is as follows: the protective device includes a connecting layer and a top layer, and the connecting layer and top layer are multi-layered, making the protective device easy to transport. After transportation, the bottom connecting layer is connected to the ground with anchor bolts, and then the aircraft is transferred to the connecting layer. During the aircraft's erection, the multi-layered connecting layers are quickly hoisted and positioned using a positioning device, and then the adjacent connecting layers, as well as the left connecting layer 11 and the right connecting layer 21, are connected using a locking device, thus completing the modular, quick-release launch site protection device assembly. Before launch, a truck crane is used to open the left top layer 12 and right top layer 22 on the top left and right modules to clear the takeoff area, and the quick-release baffle 61 is opened to form a tail flame guide channel. This achieves the protective device's function of protecting the aircraft from wind, rain, and dust before takeoff, and also allows for quick assembly and disassembly to meet the pre-launch workflow for flight tests.
[0038] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims of the present invention.
