Description

Technical Field

[0001] The present invention relates to the field of aerospace, and particularly to a mounting and fastening device for helicopter simulation training equipment. Background Art

[0002] Existing fastening devices for helicopter external suspension simulation training for test purposes generally cannot fully simulate the original aircraft's mounting and fastening method to fasten and install airborne external equipment, lacking a suspension hook and a pressing and leveling function consistent with the original aircraft's installation method. During the test process, the real application scenario cannot be fully restored, or the resonance phenomenon of the product during vibration leads to damage to the test equipment.

[0003] Existing pod fastening tooling has many defects. Most traditional tooling has a simple structure and is difficult to accurately simulate the locking and fixing method of helicopter weapon pylons. As a result, during the vibration test, the fixed state of the pod is quite different from that during actual flight, and the test results lack accuracy and reliability. Moreover, existing tooling often has poor versatility, and different tooling needs to be designed for different models and specifications of pods, increasing the test cost and preparation time. In addition, during the vibration test process, the stability and anti-vibration ability of the tooling itself are insufficient, and problems such as loosening and deformation are likely to occur, which not only affects the smooth progress of the test but may also damage the pod. The helicopter weapon pylon has developed an efficient and reliable locking and fixing method in long-term practice, which can ensure the stable mounting of weapons in a complex flight vibration environment. Therefore, it is of great practical significance to develop a new type of pod fastening device for vibration tests by referring to the principle of helicopter weapon pylons.

[0004] It can be seen that there are the following problems: In the prior art, large helicopter simulation training equipment has resonance problems during vibration tests due to unreasonable design of the mounting and fastening device. Summary of the Invention

[0005] For this reason, the present invention provides a mounting and fastening device for helicopter simulation training equipment to overcome the resonance problem caused by unreasonable design of the mounting and fastening device of large helicopter simulation training equipment during vibration tests in the prior art.

[0006] To achieve the above object, the present invention provides a mounting and fastening device for helicopter simulation training equipment, including: A support assembly, which includes a first support plate, a second support plate, a third support plate, a fourth support plate, a fifth support plate, a sixth support plate, a seventh support plate, an eighth support plate, a first side panel, a second side panel, a bottom panel, a first connecting bar, and a second connecting bar. The support assembly is used to support the weight of the helicopter simulation training equipment; The hoisting mechanism is connected to the support assembly and includes a first hook, a second hook, and a top plate. The first hook and the second hook are disposed vertically upward from the vertical center of the top plate, and the first hook and the second hook are symmetric with respect to the horizontal center line of the top plate. Both ends of the top plate are respectively connected to the end points of the side ends of the first to fourth support plates and the end points of the side ends of the fifth to eighth support plates. The helicopter simulation training equipment is hoisted by the first hook and the second hook. The pressing mechanism is connected to the hoisting mechanism and includes four pressing block assemblies, four ball head bolts, and four ball head bolt fixing seats. The ball head end of the ball head bolt is connected to the pressing block assembly, and the bolt end of the ball head bolt is connected to the ball head bolt fixing seat. The pressing block assembly presses the helicopter simulation training equipment through the ball head bolt.

[0007] Further, the inclined ends of the first to fourth support plates are connected to the first connecting bar by bolts, the inclined ends of the fifth to eighth support plates are connected to the second connecting bar by bolts, the first side panel is connected to the side ends of the first to fourth support plates, the second side panel is connected to the side ends of the fifth to eighth side panels, and the bottom panel is respectively connected to the bottoms of the first to eighth, one end of the first side panel, and one end of the second side panel.

[0008] Further, the first to fourth support plates are evenly distributed on the first side panel and the first to fourth support plates are arranged in parallel, and the fifth to eighth support plates are evenly distributed on the second side panel and the fifth to eighth support plates are arranged in parallel.

[0009] Further, the pressing block assembly is formed by splicing two cubes. A spherical socket is designed in the middle of the pressing block assembly. When the two cubes are spliced, the ball head of the ball head bolt is wrapped, so that the ball head of the ball head bolt can rotate smoothly in the socket of the pressing block assembly.

[0010] Further, the installation spacing between the first hook and the second hook is the same as that of the hook of the helicopter external hanging locking device, and the spacing between the pressing block assemblies is the same as the spacing of the helicopter external hanging locking device.

[0011] Further, both the first hook and the second hook adopt a split design, including a hook body and a hook fixing seat. The hook fixing seat is fixedly connected to the top plate and is used to support and fix the hook body. The hook body is in an open shape and is used for the suspension and installation of the equipment.

[0012] Further, an opening is provided at the center of one end of the top plate to provide a positioning point.

[0013] Furthermore, a cross structure is provided in the central region of the first side panel and there are four equal hollow regions. According to the second support plate and the third support plate, the hollow regions are divided into several sub-hollow regions, and the sizes of the several sub-hollow regions are unequal and symmetrically distributed.

[0014] Furthermore, the device further includes a first antenna fixing seat and a second antenna fixing seat. The first antenna fixing seat is arranged on the first side panel between the second support plate and the third support plate, and the second antenna fixing seat is arranged on the second side panel between the sixth support plate and the seventh support plate. The first antenna fixing seat and the second antenna fixing seat are used to realize the external installation of the pod antenna.

[0015] Furthermore, it also includes a cooperation with the lifting lug of the helicopter simulation training device for fixing the helicopter simulation training device at a predetermined position.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows. Through the multi-point support design of the support assembly, the weight of the device is effectively dispersed, improving the overall stability and load-bearing capacity. The design of the hoisting mechanism enables the helicopter simulation training device to be conveniently hoisted by the first hook and the second hook, and the symmetrical layout ensures the balance of hoisting and reduces the risk during the installation process. The pressing mechanism can achieve precise pressing of the device through the cooperation of four pressing block assemblies and ball head bolts, ensuring that the device will not displace during the simulation training, improving the accuracy and safety of the training. By adopting an adjustable pressing mechanism and a flexible support assembly design, the device can adapt to helicopter simulation training devices of different models and sizes, having wide applicability. The structural design of the device simplifies the installation process of the helicopter simulation training device, reduces the installation time and labor costs, and improves the efficiency of the vibration test.

[0017] In particular, by connecting the inclined ends of the first to fourth support plates to the first connecting bar with bolts, and connecting the inclined ends of the fifth to eighth support plates to the second connecting bar with bolts, a plurality of stable triangular structures are formed, greatly enhancing the stability and anti-deformation ability of the entire support assembly. The first side panel is connected to the side ends of the first to fourth support plates, and the second side panel is connected to the side ends of the fifth to eighth support plates, providing strong lateral support for the device and effectively preventing lateral displacement of the device during the simulation training. The bottom panel is connected to the bottom ends of the first to eighth support plates and one end of the two side panels, realizing uniform distribution of the bottom support and ensuring the stability of the device during the simulation training. The bolt connection method makes the installation and disassembly of each component more convenient and fast, improving the installation efficiency.

[0018] In particular, the first to fourth support plates and the fifth to eighth support plates are evenly distributed on their respective first side panels and second side panels, ensuring that the weight of the helicopter simulation training equipment can be evenly transmitted to the support structure and avoiding local overload phenomena. By evenly distributing and parallelly arranging the support plates, the load-bearing capacity of the entire device is improved, enabling it to accommodate heavier or larger helicopter simulation training equipment.

[0019] In particular, through the spherical ball socket design, the ball head of the ball head bolt can smoothly rotate within the pressing block assembly, greatly enhancing the flexibility of the device and adapting to the installation requirements at different angles and positions. The two cubes are spliced to wrap the ball head bolt, ensuring the stable position of the ball head within the ball socket, avoiding the detachment or displacement of the bolt during vibration or movement, and improving the stability of the entire device. The cube splicing design makes the installation of the pressing block assembly more convenient, allowing splicing and fixation to be completed without complex tools, thus greatly improving the installation efficiency.

[0020] In particular, by ensuring that the distance between the hook and the pressing block assembly is the same as that of the helicopter external suspension locking device, the fixed state of the pod during helicopter flight can be more realistically simulated, thereby improving the fidelity and effect of the simulation training. Due to the consistency of the distances, the possibility of resonance between the installation fastening device and the external equipment is greatly reduced, improving the safety and reliability of the vibration test.

[0021] In particular, the split design of the hook enables the hook body to be replaced or adjusted independently of the fixed seat, adapting to the suspension requirements of different equipment and improving the flexibility and adaptability of the installation. The hook fixed seat is fixedly connected to the top plate, providing a stable support point to ensure that the hook body does not shift or shake when suspending equipment, enhancing the stability of the overall structure. The split design allows for more precise adjustment of the position and angle of the hook body, thereby optimizing the load distribution, reducing stress concentration, and improving the load-bearing capacity and safety of the device.

[0022] In particular, the opening is provided at the center of one end of the top plate, providing a clear positioning point for the hoisting of the helicopter simulation training equipment, making the hoisting process more accurate and fast. The opening design facilitates the insertion and fixation of the hoisting equipment, reducing the cumbersome operations during the hoisting process and improving the hoisting efficiency.

[0023] In particular, the design of the cross structure effectively disperses the external force, improving the overall rigidity and stability of the first side panel. The combination of the hollowed-out area and the support plate further enhances the support force of the panel and prevents deformation. Through the hollowed-out design, the use of materials is reduced, and the overall weight is lowered. The symmetrically distributed sub-hollowed-out areas ensure the uniformity of the weight distribution and avoid the center of gravity shift.

[0024] In particular, the external installation of the antenna fixing base not only optimizes space utilization and signal reception, but also improves installation flexibility, equipment safety, maintenance convenience, and simulation authenticity, while reducing the interference risk and enhancing the overall aesthetics.

[0025] In particular, through the close cooperation with the lifting lug, the fastening device can effectively resist various dynamic loads during the simulation training process, ensuring that the helicopter simulation training equipment remains stable at the predetermined position without displacement or shaking.

The first hook 501 and the second hook 502 are arranged vertically upward from the vertical center of the top plate 6. The first hook 501 and the second hook 502 are symmetric with respect to the horizontal center line of the top plate 6. Both ends of the top plate 6 are respectively connected to the endpoints of the side ends of the first to fourth support plates 104 and the endpoints of the side ends of the fifth to eighth support plates 108. The helicopter simulation training device is hoisted by the first hook 501 and the second hook 502; A pressing mechanism, connected to the hoisting mechanism, which includes four pressing block assemblies 7, four ball head bolts 8, and four ball head bolt fixing seats 9. The ball head end of the ball head bolt 8 is connected to the pressing block assembly 7, and the bolt end of the ball head bolt is connected to the ball head bolt fixing seat 9. The pressing block assembly 7 presses the helicopter simulation training device through the ball head bolt 8.

[0032] Specifically, high-strength steel or aluminum alloy is selected to ensure sufficient strength and stiffness. The material is processed into the first to eighth support plates to ensure precise dimensions. Each support plate is fixed in the designed position and connected using the first connecting bar and the second connecting bar to form a stable support structure. The first side panel, the second side panel, and the bottom panel are fixed on the support plates to form a closed support frame. The top plate is placed above the support assembly to ensure that its horizontal centerline is aligned with the support assembly. At the upward position of the vertical center of the top plate, the first lifting hook and the second lifting hook are symmetrically installed to ensure a firm connection between the lifting hooks and the top plate. The two ends of the top plate are respectively connected to the side end points of the first to fourth support plates and the fifth to eighth support plates to ensure the stability of the lifting mechanism. Four pressing block assemblies are prepared to ensure that their dimensions match the helicopter simulation training equipment. The ball head end of the ball head bolt is connected to the pressing block assembly, and the bolt end is connected to the ball head bolt fixing seat. By adjusting the ball head bolt, the pressing block assembly tightly presses the helicopter simulation training equipment to ensure that the equipment remains stable during the vibration test.

[0033] Specifically, the multi-point support design of the support assembly effectively disperses the weight of the equipment, improving the overall stability and load-bearing capacity. The design of the lifting mechanism enables the helicopter simulation training equipment to be conveniently lifted through the first lifting hook and the second lifting hook. The symmetrical layout ensures the balance of lifting and reduces the risks during the installation process. The pressing mechanism, through the cooperation of four pressing block assemblies and ball head bolts, can achieve precise pressing of the equipment, ensuring that the equipment does not displace during the simulation training process, and improving the accuracy and safety of the training. With the adjustable pressing mechanism and the flexible support assembly design, this device can adapt to helicopter simulation training equipment of different models and sizes, having wide applicability. The structural design of this device simplifies the installation process of the helicopter simulation training equipment, reduces the installation time and labor costs, and improves the efficiency of the vibration test.

[0034] Specifically, the inclined ends of the first to fourth support plates 104 are connected to the first connecting bar 401 by bolts, the inclined ends of the fifth to eighth support plates 108 are connected to the second connecting bar by bolts, the first side panel 201 is connected to the side ends of the first to fourth support plates 104, the second side panel 202 is connected to the side ends of the fifth to eighth side panels 108, and the bottom panel 3 is respectively connected to the bottom ends of the first to eighth support plates 108, one end of the first side panel 201, and one end of the second side panel 202.

[0035] Specifically, align the inclined ends of the first to fourth support plates and connect them to the first connecting bar using bolts to ensure a firm connection and keep the support plates parallel to each other. Similarly, align the inclined ends of the fifth to eighth support plates and connect them to the second connecting bar using bolts. Align the first side panel with the side ends of the first to fourth support plates and fix them using bolts or welding to ensure that the side panel is perpendicular to and tightly connected to the support plates. Align the second side panel with the side ends of the fifth to eighth support plates and also fix them using bolts or welding. Place the bottom panel at the bottom ends of the first to eighth support plates to ensure that the bottom panel is aligned with the bottom ends of each support plate. Connect the bottom panel to the bottom ends of the first to eighth support plates, one end of the first side panel, and one end of the second side panel using bolts to ensure that the bottom panel is flat and firm. Place the top panel above the support assembly to ensure that it is horizontal and located at the center of the support assembly. Align the two ends of the top panel with the side end points of the first to fourth support plates and the fifth to eighth support plates respectively, and fix them using bolts or welding.

[0036] Specifically, by connecting the inclined ends of the first to fourth support plates to the first connecting bar and the inclined ends of the fifth to eighth support plates to the second connecting bar using bolts, multiple stable triangular structures are formed, greatly enhancing the stability and anti-deformation ability of the entire support assembly. The first side panel is connected to the side ends of the first to fourth support plates, and the second side panel is connected to the side ends of the fifth to eighth support plates, providing strong lateral support for the equipment and effectively preventing lateral displacement of the equipment during simulation training. The bottom panel is connected to the bottom ends of the first to eighth support plates and one end of each of the two side panels, achieving a uniform distribution of the bottom support and ensuring the stability of the equipment during simulation training. The use of bolt connection makes the installation and disassembly of each component more convenient and fast, improving the installation efficiency.

[0037] Specifically, the first to fourth support plates 104 are evenly distributed on the first side panel 201 and the first to fourth support plates 104 are arranged in parallel, and the fifth to eighth support plates 108 are evenly distributed on the second side panel 202 and the fifth to eighth support plates 108 are arranged in parallel.

[0038] Specifically, determine the positions and dimensions of the first side panel and the second side panel. According to the weight and dimensions of the helicopter simulation training device, plan the distribution positions of the first to fourth support plates and the fifth to eighth support plates on their respective side panels to ensure uniform distribution. Machine the first to eighth support plates according to the design dimensions to ensure that the dimensions of each support plate are consistent and the edges are flat. Machine the inclined ends of the support plates so that they can be bolted to the connecting bars. Place the first to fourth support plates on the first side panel and adjust their positions to make them evenly distributed and parallel. Use measuring tools (such as rulers and spirit levels) to ensure that the distances between the support plates are equal and perpendicular to the first side panel. Connect the inclined ends of the first to fourth support plates to the first connecting bar with bolts and tighten the bolts to ensure a firm connection. Similarly, place the fifth to eighth support plates on the second side panel and adjust their positions to make them evenly distributed and parallel. Use measuring tools to ensure that the distances between the support plates are equal and perpendicular to the second side panel. Connect the inclined ends of the fifth to eighth support plates to the second connecting bar with bolts and tighten the bolts to ensure a firm connection.

[0039] Specifically, the first to fourth support plates and the fifth to eighth support plates are evenly distributed on their respective first side panel and second side panel, ensuring that the weight of the helicopter simulation training device can be evenly transmitted to the support structure and avoiding local overload. By evenly distributing and parallel arranging the support plates, the load-bearing capacity of the whole device is improved, enabling it to accommodate heavier or larger helicopter simulation training devices.

[0040] Specifically, the pressing block assembly 7 is formed by splicing two cubes. A spherical socket is designed in the middle of the pressing block assembly 7. When the two cubes are spliced, the ball head of the ball head bolt is wrapped, so that the ball head of the ball head bolt 8 can smoothly rotate in the socket of the pressing block assembly 7.

[0041] Specifically, select high-strength and wear-resistant materials (such as steel or aluminum alloy) as the base materials of the pressing block assembly. According to the design requirements, prepare two cube blocks and ensure that their dimensions and shapes conform to the design specifications. Design spherical sockets at the middle positions of each cube block, and the sizes of the sockets match the ball heads of the ball head bolts. Machine the sockets with a numerical control machine tool or precision machining equipment to ensure that the shapes and sizes of the sockets are accurate. Align the two machined cube blocks so that the positions of their sockets coincide. Place the ball head of the ball head bolt in the socket and ensure that the contact surface between the ball head and the socket is smooth. Slowly splice the two cube blocks together so that they completely wrap the ball head of the ball head bolt. Use bolts, nuts or other fixing parts to fix the two cube blocks together to ensure that they will not separate during subsequent use. Manually rotate the ball head bolt to check whether it can smoothly rotate in the socket of the pressing block assembly. If the rotation is not smooth, it may be necessary to further adjust the size or shape of the socket or lubricate the ball head.

[0042] Specifically, through the spherical ball socket design, the ball head of the ball head bolt can rotate smoothly within the pressing block assembly, greatly enhancing the flexibility of the device and meeting the installation requirements at different angles and positions. The two cubes are spliced to wrap the ball head bolt, ensuring the stable position of the ball head within the ball socket and preventing the bolt from falling off or shifting during vibration or movement, thereby improving the stability of the entire device. The cube splicing design makes the installation of the pressing block assembly more convenient, and splicing and fixing can be completed without complex tools, greatly improving the installation efficiency.

[0043] Specifically, the installation spacing between the first hook 501 and the second hook 502 is the same as that of the hook of the helicopter external hanging locking device, and the spacing of the pressing block assembly 7 is the same as that of the helicopter external hanging locking device.

[0044] Specifically, use precise measuring tools (such as calipers, laser rangefinders, etc.) to measure the spacing of the hooks on the helicopter external hanging locking device. Record the measurement data, including the horizontal distance and vertical distance between the hooks. According to the measurement data, design the corresponding hook installation positions on the installation fastening device of the simulation training equipment. Ensure that the spacing of the hooks on the design drawing is exactly the same as the spacing of the original machine's hooks. Process the hook assembly according to the design drawing. Use positioning tools and fixing devices to ensure that the hooks are positioned strictly according to the designed spacing during installation. Carry out welding or bolt fixing to ensure that the hooks are firmly installed. After installation, use the measuring tools again to verify the accuracy of the hook spacing. Make fine adjustments if necessary until it is exactly the same as the spacing of the original machine's hooks. Similarly, use precise measuring tools to measure the spacing of the pressing block assembly on the helicopter external hanging locking device. Record the detailed measurement data. According to the measurement data, design the corresponding pressing block assembly installation positions on the installation fastening device of the simulation training equipment. Ensure that the spacing of the pressing block assembly on the design drawing is the same as the spacing of the original machine's locking device. Process the pressing block assembly according to the design drawing. Use positioning tools and fixing devices to ensure that the pressing block assembly is positioned strictly according to the designed spacing during installation. Carry out bolt fixing or welding to ensure that the pressing block assembly is firmly installed.

[0045] Specifically, by ensuring that the spacing of the hooks and the pressing block assembly is the same as that of the helicopter external hanging locking device, the fixed state of the pod during helicopter flight can be more realistically simulated, thereby improving the fidelity and effect of the simulation training. Due to the consistency of the spacing, the possibility of resonance between the installation fastening device and the external hanging equipment is greatly reduced, improving the safety and reliability of the vibration test.

[0046] Specifically, both the first hook 501 and the second hook 502 adopt a split design, including a hook body and a hook fixing seat. The hook fixing seat is fixedly connected to the top plate and is used to support and fix the hook body. The hook body is in an open shape and is used for the suspension and installation of equipment.

[0047] Specifically, according to the hook size and spacing of the external hanging locking device of the helicopter, determine the size, shape and spacing of the first hook and the second hook. Ensure that the connection method between the hook fixing seat and the top plate is firm and reliable. Select a suitable metal material (such as high-strength steel) for processing. Process the hook fixing seat according to the design drawing to ensure that the part where it is connected to the top plate is accurate. Also select a suitable metal material for processing. Ensure that the opening size and shape of the hook body meet the design requirements to facilitate the suspension and installation of the equipment. Fix the hook fixing seat to the top plate, and use bolts, welding, etc. to ensure a firm connection. Check the installation position and angle of the hook fixing seat to ensure that it is perpendicular to the top plate and the position is accurate. Insert the hook body into the hook fixing seat to ensure a stable connection between the hook body and the fixing seat. Adjust the position and angle of the hook body to keep the spacing between it and other components (such as the pressing block assembly) consistent.

[0048] Specifically, the split design of the hook enables the hook body to be replaced or adjusted independently of the fixing seat, adapting to the hanging requirements of different equipment and improving the flexibility and adaptability of installation. The hook fixing seat is fixedly connected to the top plate, providing a stable support point to ensure that the hook body will not shift or shake when hanging the equipment, enhancing the stability of the overall structure. The split design allows for more precise adjustment of the position and angle of the hook body, thereby optimizing the load distribution, reducing stress concentration, and improving the load-bearing capacity and safety of the device.

[0049] Specifically, an opening is provided at the center of one end of the top plate 6 to provide a positioning point.

[0050] Specifically, the opening is provided at the center of one end of the top plate, providing a clear positioning point for the hoisting of the helicopter simulation training equipment, making the hoisting process more accurate and fast. The opening design facilitates the insertion and fixation of the hoisting equipment, reduces the cumbersome operations during the hoisting process, and improves the hoisting efficiency.

[0051] Specifically, as Figure 4 shown, the central area of the first side panel 201 is provided with a cross structure and has four equal hollow areas. According to the connection between the second support plate 102 and the third support plate 103 and the first side panel 201, the hollow areas are divided into several sub-hollow areas, and the sizes of the several sub-hollow areas are unequal and symmetrically distributed.

[0052] Specifically, according to the overall size of the first side panel, determine the scope of the central area to ensure that the cross structure and the hollow area are arranged within this range. Select the shape of the cross structure, such as an "X" shape. Determine the size of the cross structure, including arm length, arm width, etc., to ensure that the structure is stable and beautiful. On the basis of the cross structure, plan four equal hollow areas, each of which is a rectangle or other regular shape. According to the size of the first side panel and the position of the hollow area, ensure that the support plate is firmly connected to the first side panel and can divide the hollow area into several sub-hollow areas. Select a suitable connection method, such as bolt connection, to ensure that the connection between the support plate and the first side panel is firm and stable. According to the position of the second support plate and the third support plate, divide the four equal hollow areas into several sub-hollow areas. Ensure that the sub-hollow areas are of different sizes but symmetrically distributed to achieve the beauty and functionality of the design.

[0053] Specifically, the cross structure design effectively disperses external forces and improves the overall rigidity and stability of the first side panel. The combination of the hollow area and the support plate further enhances the support force of the panel and prevents deformation. The hollow design reduces the use of materials and reduces the overall weight. The symmetrically distributed sub-hollow areas ensure uniform weight distribution and avoid center of gravity shift.

[0054] Specifically, the device also includes a first antenna fixing seat 111 and a second antenna fixing seat 112, the first antenna fixing seat 111 is arranged on the first side panel between the second support plate 102 and the third support plate 103, and the second antenna fixing seat 112 is arranged on the second side panel between the sixth support plate 106 and the seventh support plate 107, and the first antenna fixing seat 111 and the second antenna fixing seat 112 are used to realize the external installation of the pod antenna.

[0055] Specifically, mounting holes for the fixing base are processed on the side panels between the second support plate and the third support plate and between the sixth support plate and the seventh support plate. The first antenna fixing base and the second antenna fixing base are fixed to the side panels by bolts or other fasteners. The pod antenna is externally mounted to the first antenna fixing base and the second antenna fixing base to ensure a firm connection between the antenna and the fixing base. When it is necessary to fasten the communication antenna installed at the bottom of the training equipment pod to exceed the installation height, the communication antenna can be transferred and installed and fixed to the antenna fixing base position by transferring the feeder, thereby further improving the versatility of the installation and fixing device.

[0056] Specifically, the external installation of the antenna holder not only optimizes space utilization and signal reception, but also improves installation flexibility, equipment safety, maintenance convenience and simulation realism, while reducing interference risks and improving overall aesthetics.

[0057] Specifically, it also includes cooperating with the lugs of the helicopter simulation training device for fixing the helicopter simulation training device at a predetermined position.

[0058] Specifically, clean the lugs of the helicopter simulation training device to ensure that there are no impurities such as oil stains and dust. Check whether the lugs are damaged or deformed. If so, repair or replace them as needed. Align the connecting part of the fastening device with the lugs to ensure a tight fit. Use fasteners such as bolts and nuts to fix the fastening device on the lugs to ensure firmness and accuracy. Lift and install the helicopter simulation training device at a predetermined position.

[0059] Specifically, the lugs for installing the fastening device on the helicopter simulation training device are designed in combination with the dimensions of the external hanging device installation lugs of the original aircraft. The distance between the two lugs is kept consistent with the distance between the original aircraft hanging brackets, and various external hanging devices can be hoisted. First, suspend and install the 2 lugs of the helicopter simulation training device on the 2 hooks of the fastening device for the helicopter simulation training device, and adjust the external hanging device to a horizontal state. Then, rotate the 4 ball head bolts clockwise respectively to drive the pressing block to slightly fit with the fixed surface of the external hanging device. While the external hanging device is kept horizontally suspended, tighten the 4 ball head bolts at one time until the external hanging device is completely pressed. Finally, tighten the fastening nuts of the ball head bolts to ensure that the ball head bolts do not loosen during the vibration of the external hanging device.

[0060] Specifically, through the tight fit with the lugs, the fastening device can effectively resist various dynamic loads during the simulation training process, ensuring that the helicopter simulation training device remains stable at a predetermined position without displacement or shaking.
