Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rocket engine, in particular to a large-thrust liquid rocket engine water platform and a mounting method thereof. BACKGROUND

[0002] The large-thrust liquid rocket engine is the core power device of the carrier rocket and the spacecraft. Before being officially launched into the sky, it must undergo a large number of ground thermal test checks to simulate various working conditions to verify its performance, reliability and working stability.

[0003] The traditional large-thrust engine test is mostly carried out on a vertical test stand, which has the advantage that the working posture of the engine is consistent with the flight state. However, the vertical stand has the disadvantages of high construction difficulty, high cost (extremely high truss and flow guide groove), inconvenient installation and maintenance, etc. The horizontal test stand has the advantages of low construction cost, simple structure and convenient installation and maintenance, but it is mostly used for engine test of about ten tons of thrust. During the test, the head and tail of the engine are usually only simply supported to prevent the engine from shaking, and the material strength of the horizontal test stand is relied on to offset the thrust of the engine.

[0004] However, when the above horizontal test stand is used for test of a hundred-ton large-thrust engine, the huge axial thrust is difficult to offset only by the material strength of the test stand, which causes the horizontal test stand to be easily deformed, affecting the test. SUMMARY

[0005] The main purpose of the present application is to provide a large-thrust liquid rocket engine water platform and a mounting method thereof, which aims to solve the problem that the traditional horizontal test stand is easily deformed when bearing a huge axial thrust.

[0006] To achieve the above-mentioned purpose, the present application provides a large-thrust liquid rocket engine water platform for connecting an engine, which comprises a base, a vertical plate, a reinforcing plate, a fixed stand and an auxiliary support assembly. The vertical plate is vertically arranged on one side of the base. The reinforcing plate is connected to one side of the vertical plate and connected with the base, wherein the reinforcing plate is perpendicular to the vertical plate and the base respectively. The fixed stand is fixed to one side of the vertical plate away from the reinforcing plate. The side of the fixed stand away from the vertical plate is used for fixing the end of the engine, and the axial direction of the engine is perpendicular to the vertical plate. The auxiliary support assembly is arranged on the base to support the end of the engine away from the vertical plate.

[0007] Optionally, the base comprises a high-strength base and a common base arranged in the axial direction of the engine. The vertical plate and the reinforcing plate are arranged on the high-strength base, and the auxiliary support assembly is arranged on the common base.

[0008] Optionally, there are two vertical plates spaced apart in their thickness direction, and each vertical plate has a first through hole; there are two reinforcing plates spaced apart in their thickness direction; the high-thrust liquid rocket engine platform frame also includes a surrounding plate, which is disposed between the two vertical plates to connect the two vertical plates.

[0009] Optionally, in the thickness direction of the vertical plate, the projections of the surrounding plate and the reinforcing plate on the vertical plate are both located around the first through hole.

[0010] Optionally, the high-strength base includes a steel base plate, two first steel plates, and a horizontal plate. The two first steel plates are respectively disposed on both sides of the steel base plate. The horizontal plate is connected to the side of one of the first steel plates away from the steel base plate by bolts and threads. The one of the two first steel plates away from the horizontal plate is connected to a bolt pre-embedded in the ground. The horizontal plate is connected to the vertical plate and the reinforcing plate.

[0011] Optionally, the high-strength base further includes a fixing block and an adjusting bolt. The fixing block is disposed on the edge of the horizontal plate and fixed to the first steel plate by bolts. The adjusting bolt is inserted into the fixing block along the side of the fixing block away from the horizontal plate. The adjusting bolt is threadedly connected to the fixing block, and the axial direction of the adjusting bolt is the same as the axial direction of the engine.

[0012] Optionally, the fixed frame includes a base plate and a panel, the base plate being fixed to the vertical plate; the panel being fixed to the side of the base plate away from the vertical plate and having a gap between it and the base plate, wherein the panel has a plurality of screw holes for connecting the engine.

[0013] Optionally, both the base plate and the panel are provided with a second through hole.

[0014] Optionally, the auxiliary support assembly includes a mounting plate, a vertical beam, a second steel plate, and a clamp. The mounting plate is stacked on top of the base. The vertical beam is vertically fixed to the side of the mounting plate away from the base. The second steel plate is fixed to the end of the vertical beam away from the mounting plate, and the end of the engine away from the fixed frame is located on the side of the second steel plate away from the vertical beam. The clamp is bolted to the side of the second steel plate away from the vertical beam to press the engine.

[0015] In addition, this application also provides an installation method for the above-mentioned high-thrust liquid rocket engine platform frame. The installation method includes: pouring a cement foundation and pre-embedding high-strength bolts; hoisting the base onto the cement foundation and connecting it with the high-strength bolts; sequentially connecting the vertical plate, the reinforcing plate, and the fixed platform; hoisting the engine onto the base to connect the engine to the fixed platform; and installing an auxiliary support assembly to support the end of the engine away from the vertical plate.

[0016] The embodiments of this application propose a horizontal platform frame for a high-thrust liquid rocket engine. The vertically installed vertical plate, reinforcing plate, and base form a triangular stable structure. During the test of the high-thrust engine, the axial thrust of the engine is applied to the vertical plate through the fixed frame and transmitted to the base through the reinforcing plate, forming a stable support. This counteracts the axial thrust of the hundred-ton-class high-thrust engine and effectively prevents deformation of the vertical plate, reinforcing plate, base, and other components of the horizontal test platform, resulting in better performance.

[0023] refer to Figures 1-5 This application provides a platform frame for a high-thrust liquid rocket engine, used to connect an engine 1. The platform frame may include a base 2, a vertical plate 3, a reinforcing plate 4, a fixing frame 5, and an auxiliary support assembly 6. The vertical plate 3 is vertically disposed on one side of the base 2; the reinforcing plate 4 is connected to one side of the vertical plate 3 and to the base 2, wherein the reinforcing plate 4 is perpendicular to both the vertical plate 3 and the base 2; the fixing frame 5 is fixed to the side of the vertical plate 3 away from the reinforcing plate 4, and the side of the fixing frame 5 away from the vertical plate 3 is used to fix the end of the engine 1, the axis of the engine 1 being perpendicular to the vertical plate 3; the auxiliary support assembly 6 is disposed on the base 2 to support the end of the engine 1 away from the vertical plate 3.

[0024] The embodiment of this application proposes a horizontal platform frame for a high-thrust liquid rocket engine. The vertically installed vertical plate 3, reinforcing plate 4, and base 2 form a triangular stable structure. When the high-thrust engine 1 is tested, the axial thrust of the engine 1 is applied to the vertical plate 3 through the fixed platform 5 and transmitted to the base 2 through the reinforcing plate 4, forming a stable support. This effectively counteracts the axial thrust of the hundred-ton-class high-thrust engine and effectively prevents deformation of the vertical plate 3, reinforcing plate 4, base 2, and other components of the horizontal test platform, resulting in better performance.

[0025] One end of the engine 1 is fixed to the fixed frame 5, and the other end is supported by the auxiliary support assembly 6 to ensure that the engine 1 is axially horizontal.

[0026] It should be noted that during use, the thickness direction of the base 2 can be the same as the direction of gravity, and the reinforcing plate 4, the vertical plate 3, and the auxiliary support components 6 can all be set on the top of the base 2.

[0027] Among them, the vertical plate 3, the reinforcing plate 4, and the base 2 can all be made of steel to improve the overall structural strength.

[0028] refer to Figure 1 In an exemplary embodiment, the base 2 may include a high-strength base 21 and a regular base 22 arranged axially on the engine 1; wherein the vertical plate 3 and the reinforcing plate 4 are both disposed on the high-strength base 21, and the auxiliary support assembly 6 is disposed on the regular base 22.

[0029] Among them, the high-strength base 21 and the ordinary base 22 can be fixed relatively. The high-strength base 21 is made of a high-strength material to connect with the reinforcing plate 4 and the vertical plate 3 to withstand the thrust of the high-thrust engine 1. The ordinary base 22 only needs to be connected with the auxiliary support component 6 to support the engine 1.

[0030] By using a high-strength base 21 only in the core load-bearing area, the overall manufacturing cost of the base 2 can be significantly reduced.

[0031] refer to Figure 2 and Figure 3 In an exemplary embodiment, there are two vertical plates 3, which are spaced apart in the thickness direction, and each vertical plate 3 has a first through hole; there are two reinforcing plates 4, which are spaced apart in the thickness direction; the high-thrust liquid rocket engine platform frame may also include a surrounding plate 31, which is disposed between the two vertical plates 3 to connect the two vertical plates 3.

[0032] It should be understood that by using two vertical plates 3 and two reinforcing plates 4 for support, the overall load-bearing capacity of the structure can be further improved, and deformation of each component can be prevented.

[0033] The two vertical plates 3, the surrounding plate 31, and the reinforcing plate 4 can be welded together; in addition, reinforcing ribs can be set between the two vertical plates 3 to improve the stability of the two vertical plates 3, and the reinforcing ribs can be set on the periphery of the surrounding plate 31.

[0034] Furthermore, the vertical plate 3 has a first through hole, which facilitates the passage of some pipes through the first through hole and the connection of the fixed frame 5 to the engine 1.

[0035] In the exemplary embodiment, in the thickness direction of the vertical plate 3, the projections of the surrounding plate 31 and the reinforcing plate 4 on the vertical plate 3 are both located around the first through hole. Thus, in the axial direction of the engine 1, the surrounding plate 31 and the reinforcing plate 4 will not obstruct the first through hole, making the pipeline layout more convenient.

[0036] The oxidizer lines, fuel lines, air lines, cooling water lines, and control cables required for engine 1 can all be supported by brackets mounted on the high-strength base 21. Furthermore, the oxidizer lines can be insulated to reduce heat loss. Anti-vibration clamps can be installed on each bracket to hold the lines or cables, further reducing the impact of engine vibration on them.

[0037] All pipes and cables are connected to engine 1. When replacing engine 1 with a different model, simply disconnect engine 1. The operation is convenient and quick.

[0038] refer to Figure 2 In an exemplary embodiment, the high-strength base 21 may include a steel base plate 211, two first steel plates 212, and a horizontal plate 213. The two first steel plates 212 are respectively disposed on both sides of the steel base plate 211. The horizontal plate 213 is connected to the side of one of the first steel plates 212 away from the steel base plate 211 by bolts and threads. The one of the two first steel plates 212 that is away from the horizontal plate 213 is connected to a bolt pre-embedded in the ground. The horizontal plate 213 is connected to the vertical plate 3 and the reinforcing plate 4.

[0039] Specifically, the steel base plate 211 can be formed by welding H-shaped or I-shaped steel sections with intersecting horizontal and vertical lines. During installation, a first steel plate 212 is welded to each side of the steel base plate 211 to improve the overall strength of the steel base plate 211.

[0040] like Figure 2As shown, the upper first steel plate 212 is also bolted to the horizontal plate 213, which can be welded to the vertical plate 3 and the reinforcing plate 4. The lower first steel plate 212 is connected to the high-strength bolts pre-embedded in the cement foundation, and the bonding force between the first steel plate 212 and the cement foundation can be enhanced by secondary grouting. In this way, the overall load-bearing capacity of the high-thrust liquid rocket engine platform frame is further improved through the structure of the high-strength base 21 and components such as the vertical plate 3 and the reinforcing plate 4, preventing deformation problems during use.

[0041] refer to Figure 2 and Figure 3 In an exemplary embodiment, the high-strength base 21 may further include a fixing block 214 and an adjusting bolt 215. The fixing block 214 is disposed on the edge of the horizontal plate 213 and fixed to the first steel plate 212 by bolts. The adjusting bolt 215 is inserted into the fixing block 214 along the side of the fixing block 214 away from the horizontal plate 213. The axial direction of the adjusting bolt 215 is the same as that of the engine 1.

[0042] Specifically, the horizontal plate 213, the vertical plate 3, and the reinforcing plate 4 are considered as the load-bearing structure, while the steel base plate 211 and the first steel plate 212 are considered as the supporting structure. During installation, the load-bearing structure is first placed on the supporting structure, that is, the horizontal plate 213 is placed on the first steel plate 212, and the fixing block 214 is fixed to the first steel plate 212 with bolts. At this time, the adjusting bolt 215 is screwed into the fixing block 214. In this way, by turning the adjusting bolt 215, the adjusting bolt can be made to abut against the horizontal plate 213 and push the horizontal plate 213 to move axially in the engine 1. This facilitates fine adjustment of the distance between the fixed frame 5 and the auxiliary support assembly 6, and facilitates the installation of the engine 1.

[0043] refer to Figure 4 In an exemplary embodiment, the mounting frame 5 may include a base plate 51 and a panel 52. The base plate 51 is fixed to the vertical plate 3. The panel 52 is fixed to the side of the base plate 51 away from the vertical plate 3 and has a gap between it and the base plate 51. The panel 52 has a plurality of screw holes for connecting the engine 1.

[0044] Specifically, the multiple screw holes on the panel 52 can be arranged in an array to facilitate the connection of different models of engine 1 by screws; of course, an adapter can also be connected to the panel 52 to connect different models of engine 1 by using different models of adapters.

[0045] Furthermore, in an exemplary embodiment, both the base plate 51 and the panel 52 are provided with second through holes. Thus, both the base plate 51 and the panel 52 are annular, allowing the pipes or cables required by the engine 1 to pass through the second through holes to connect to the end of the engine.

[0046] refer toFigure 5 In an exemplary embodiment, the auxiliary support assembly 6 may include a mounting plate 61, a vertical beam 62, a second steel plate 63, and a clamp 64. The mounting plate 61 is stacked on top of the base 2. The vertical beam 62 is vertically fixed to the side of the mounting plate 61 away from the base 2. The second steel plate 63 is fixed to the end of the vertical beam 62 away from the mounting plate 61, and the end of the engine 1 away from the fixed frame 5 is located on the side of the second steel plate 63 away from the vertical beam 62. The clamp 64 is bolted to the side of the second steel plate 63 away from the vertical beam 62 to press the engine 1.

[0047] Specifically, the second steel plate 63 supports the end of the engine 1 away from the vertical plate 3 to maintain the axial horizontality of the engine 1; the clamp 64 squeezes and fixes the engine 1. The clamp 64 can be arc-shaped to fit the outer periphery of the throat of the engine 1 more closely, so that the clamp 64 can squeeze and fix the engine.

[0048] Of course, the second steel plate 63 can also be arc-shaped to support the curved outer periphery of the engine.

[0049] Furthermore, a telescopic mechanism can be installed below the mounting plate 61 to adjust the height of the second steel plate 63, further supporting different engine models. Traditional telescopic mechanisms are common, such as hydraulic cylinders, and will not be elaborated upon here.

[0050] In addition, such as Figure 5 As shown, the auxiliary support assembly 6 may also include an inclined beam 65, the axial direction of which is at an acute angle to the axial direction of the vertical beam 62. The inclined beam 65 connects the second steel plate 63 and the mounting plate 61, thereby further improving the stability of the second steel plate 63.

[0051] There can be two vertical beams 62 and two diagonal beams 65; the vertical beams 62, diagonal beams 65 and mounting plate 61 can all be made of channel steel.

[0052] In addition, the clamp 64 can be fitted with a fluororubber buffer layer, which can absorb vibration displacement of ±5mm and prevent scratches on the engine housing. In practical applications, the clamp 64 can be controlled to prevent deformation of the engine housing by squeezing.

[0053] Furthermore, the holes in the connection area between the second steel plate 63 and the clamp 64 are oblong holes, and the holes in the connection area between the mounting plate 61 and the ordinary base 22 are also oblong holes. The long axis directions of the oblong holes at the two locations are perpendicular to each other, so that the clamp 64 can be adjusted in the long axis direction of the two oblong holes.

[0054] refer to Figure 6 Based on the above embodiments, this application also provides an installation method applied to the aforementioned high-thrust liquid rocket engine platform frame. The installation method may specifically include the following steps: S100, pour cement foundation and pre-embed high-strength bolts; S200. Hoist the base 2 onto the concrete foundation and connect it with high-strength bolts. S300, connect vertical plate 3, reinforcing plate 4, and fixed frame 5 in sequence; S400, Hoist the engine 1 onto the base 2 to connect the engine 1 to the fixed frame 5; S500, install auxiliary support assembly 6 to support the end of engine 1 away from vertical plate 3.

[0055] Specifically, in step S100, the flatness of the foundation surface needs to be controlled within 1 mm.

[0056] In step S200, the levelness of the base 2 should be within 0.05°.

[0057] In step S300, it is necessary to ensure that the verticality of the side of the fixed stand 5 where the engine 1 is installed is within 0.08° / m.

[0058] In step S500, the position of the clamp 64 of the auxiliary support assembly 6 is adjusted in two directions to the engine throat to adapt to the specific position of the engine throat.

[0059] It should be noted that if the above-mentioned scheme of welding horizontal plate 213, vertical plate 3 and reinforcing plate 4 is adopted, then in step S200, the support structure is hoisted onto the cement foundation and connected with high-strength bolts.

[0060] In step S300, the load-bearing structure is hoisted onto the supporting structure and then adjusted and connected.

[0061] It should be understood that after installation, oxidizer lines, fuel lines, and gas lines can be configured according to the positions of the pipe interfaces on engine 1, and corresponding pipe support frame structures can be made.

[0062] In actual use, when the engine with a thrust of 100 tons was tested and verified, a 200-second hot test was conducted. It was found that the maximum deformation at the vertical plate 3 and the reinforcing plate 4 was ≤1mm, and the engine 1 was fixed without loosening and there was no leakage in the pipeline. Therefore, it can meet the support requirements of a high-thrust rocket engine.

[0063] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
