Description

Technical Field

[0001] This invention belongs to the field of aircraft external structure technology and relates to an integrated multi-functional sling device. Background Technology

[0002] The development of domestic airborne electronic pods and their pods has primarily evolved from external electronic jamming or electronic reconnaissance pods mounted on fighter jets or bombers. Currently, airborne electronic equipment is developing rapidly, and adding external airborne pods is the most effective way to quickly and effectively improve the combat effectiveness of existing aircraft. Therefore, the electronic pods currently under development are being mass-produced and deployed to the armed forces, significantly enhancing their information-based combat capabilities.

[0003] To enhance the functionality of pods and accommodate more equipment, the pod cross-section is often designed as a rectangular structure. However, designing a suspension structure on such a rectangular pod presents significant limitations. Firstly, the height distance between the upper surface of the pod and the aircraft pylon is very short. Secondly, the smooth, slightly curved surface of the pod's upper surface is not conducive to load-bearing.

[0004] The pod hoisting device is the load-bearing point of the entire pod, and most of the weight of the pod's mechanical structure is concentrated in this area. The rigidity and strength of the device must fully meet the requirements. The functions to be achieved by the entire device need to be highly integrated, but the available space and weight are limited.

[0005] Traditional pod-mounted gantry systems consist of two spreader beams, with the pod's attachment point located on both beams. This two-beam design has limited rigidity, and its balance, manufacturing consistency, and assembly precision are not ideal. Furthermore, the main power interface and the launch point support are each independently designed between the two beams. This decentralized layout leads to cumbersome assembly and low precision, while also increasing the pod's aerodynamic drag and negatively impacting the aircraft's aerodynamics.

[0028] The specific embodiments of the present invention will be described below with reference to the accompanying drawings and examples.

[0029] In the following embodiments, the description of the up and down directions refers to the direction of the pod when it is suspended on the aircraft; that is, the up and down directions refer to the up and down directions of the pod.

Figure 2 This is a schematic diagram of the left-side structure of the hanging device in an embodiment of the present invention. Figure 3 This is an exploded view of the hanging device in an embodiment of the present invention.

[0032] like Figures 1 to 3 As shown, this embodiment provides an integrated multi-functional sling device 100, installed on the pod's body, for suspending the pod from an aircraft pylon. The pod includes the sling device 100 and the pod body, with the top of the pod body used to mount the sling device 100. The pod body is roughly rectangular, with its outer surface being curved.

[0033] The hanging device 100 has a lifting beam body 1, a lifting lug seat 2, a lifting lug 3, and a power socket 4.

[0034] The material of the lifting beam body 1 is 7050-T7451 aluminum alloy, and the material of the lifting lug 3 is alloy steel that meets the suspension strength requirements of the pod, so as to ensure that it will not deform or break after the pod is suspended.

[0035] Figure 4 This is a three-dimensional structural diagram of the lifting beam body in an embodiment of the present invention. Figure 1 . Figure 5 This is a top view of the main body of the suspension beam in an embodiment of the present invention. Figure 6 This is a three-dimensional structural diagram of the lifting beam body in an embodiment of the present invention. Figure 2 . Figure 7 This is a bottom view structural diagram of the suspension beam body in an embodiment of the present invention.

[0036] like Figures 4-7 As shown, the main body 1 of the suspension beam is long and narrow, resembling a horizontal beam, and is a one-piece molded structure.

[0037] The four sides of the lifting beam body 1 include two long sides and two short sides. The length of the long side is 1490mm, and the length of the end side is 250mm.

[0038] The lifting beam body 1 has a first inclined part 11, an arc-shaped part 12, a second inclined part 13, a first cavity 14, a second cavity 15, a third cavity 16, an edge reinforcement part 17, a lifting lug mounting hole 18, an inclined support 19, a drop point column 20, a power supply mounting hole 21, a first connecting hole 22, and a second connecting hole 23.

[0039] The centerline of the lifting beam body 1 in its longitudinal direction is as follows: Figure 5 and Figure 7 The center line XX is shown.

[0040] like Figure 4 and Figure 5 As shown, the lifting beam body 1 has two first inclined portions 11, which extend inclinedly from the two long sides of the lifting beam body 1 toward the center line XX. The upper surface of the first inclined portion 11 is an inclined plane that smoothly transitions with the curved surface of the cabin.

[0041] The first inclined section 11 has the same curvature as the inclined surface of the top of the cabin.

[0042] The arc-shaped portion 12 is arc-shaped and connects the two first inclined portions 11. The arc of the arc-shaped portion 12 protrudes upward toward the upper part of the suspension beam body 1, that is, it protrudes toward the direction of the aircraft pylon.

[0043] The lifting beam body 1 has two second inclined portions 13, which extend inclinedly from the two short sides of the lifting beam body 1 toward the center line YY. The upper surface of the second inclined portion 13 is an inclined plane.

[0044] The second inclined portion 13 intersects with the first inclined portion 11 and the arc-shaped portion 12, and an arc-shaped intersection line is formed at the intersection. In other words, the shape of the part where the second inclined portion 13 connects with the first inclined portion 11 and the arc-shaped portion 12 is arc-shaped.

[0045] The first inclined portion 11, the arc-shaped portion 12, and the second inclined portion 13 are all thin plate structures.

[0046] The first cavity 14, the second cavity 15, and the third cavity 16 are arranged as follows: Figure 6 and Figure 7 The items shown are arranged sequentially from left to right at the bottom of the lifting beam body 1.

[0047] The edge reinforcement 17 is arranged around the suspension beam body 1, extending from the bottom periphery of the suspension beam body 1 to intersect with the corresponding first inclined portion 11 and then the second inclined portion 14. Specifically, the edge reinforcement 17 is the thicker edge around the suspension beam body 1.

[0048] The lifting beam body 1 is provided with a pair of lifting lug mounting holes. In this embodiment, the lifting beam body 1 is provided with a pair of lifting lug mounting holes. This pair of lifting lug mounting holes includes a first lifting lug mounting hole 181 and a second lifting lug mounting hole 182.

[0049] The first lifting lug mounting hole 181 is located between the first cavity 14 and the second cavity 15, and passes through the lifting beam body 1. Its center is located on the center line XX. That is to say, the second lifting lug mounting hole 181 is symmetrical about the center line XX.

[0050] Figure 8 This is a cross-sectional view of the lifting beam body at the lifting lug mounting hole in an embodiment of the present invention.

[0051] like Figure 8 As shown, the upper opening of the first lug mounting hole 181 is provided on the arc-shaped portion 12, and has a portion extending upward from the arc-shaped portion 12. The end face of the upper opening (the top end face of the first lug mounting hole 181) is parallel to the ground of the lifting beam body 1.

[0052] The bottom periphery of the first lifting lug mounting hole 181 has four blind holes arranged around the first lifting lug mounting hole 181.

[0053] The second lifting lug mounting hole 182 is located between the second cavity 15 and the third cavity 16, penetrating the lifting beam body 1. Its center is located on the center line XX, meaning that the second lifting lug mounting hole 181 is symmetrical about the center line XX. The upper opening of the second lifting lug mounting hole 182 is provided on the arc-shaped portion 12, just like the first lifting lug mounting hole 181, and has a portion extending upward from the arc-shaped portion 12. Furthermore, the end face of this upper opening (the top end face of the second lifting lug mounting hole 182) is parallel to the ground of the lifting beam body 1.

[0054] The inner holes of the first lifting lug mounting hole 181 and the second lifting lug mounting hole 182 are configured to fit the shape of the lifting lug seat, and have hole sections with different inner diameters. The two lifting lug seats 2 are respectively fixedly installed in the first lifting lug mounting hole 181 and the second lifting lug mounting hole 182.

[0055] Two lugs 3 are fixedly installed in their respective lug seats 2. The aircraft pylon has a mechanism that cooperates with the lugs 3, so that the lugs 3 can be connected to the pylon.

[0056] In this embodiment, the two lugs 3 meet the general design guidelines for the joint parts of airborne suspensions and suspension devices in GJB1C-2006. The distance between the two lugs 3 is set to 762mm ± 0.8mm according to the requirements for Class II weight suspensions in GJB1C-2006.

[0057] The lifting lug 3 has a hook 31 for contacting and connecting with the aircraft's pylon. The distance H between the position where the hook 31 contacts the pylon and the upper surface of the pod (i.e., the top end face of the lug mounting hole) meets the requirement of 34.5mm to 36.5mm.

[0058] The center line between the first lug mounting hole 181 and the second lug mounting hole 182 is as follows: Figure 5 and Figure 7 The centerline YY is shown. The lifting beam body 1 has multiple diagonal supports 19, which are located between the first cavity 14 and the second cavity 15, and between the second cavity 15 and the third cavity 16, respectively. The diagonal supports 19 extend from one long side of the lifting beam body 1 to the other long side and are parallel to the centerline YY.

[0059] The lifting beam body 1 has two launching columns 20, which are symmetrically distributed along the central YY axis and located within the second cavity 15, that is, between the first lifting lug mounting hole 181 and the second lifting lug mounting hole 182. In this embodiment, the distance between the two launching columns 20 is 580mm. The launching columns 20 are used to provide force support during the ejection of the pod.

[0060] Figure 9 This is a cross-sectional view of the lifting beam body at the power supply mounting hole in an embodiment of the present invention.

[0061] like Figure 7 and Figure 9 As shown, the power mounting hole 21 is located at the center of the first cavity 14, passing through the arc-shaped portion 12. The power socket 4 is fixedly installed in the power mounting hole 21, and is connected to the power supply on the aircraft to supply power to the electronic equipment in the pod.

[0062] like Figure 9 As shown, the power mounting hole 21 penetrates the arc-shaped part 12 to form an opening with an arc-shaped cross-section.

[0063] The lifting beam body 1 has a first connecting hole 22 and a second connecting hole 23 distributed around its perimeter. The lifting beam body is fixedly installed onto the upper surface of the cabin by means of a connector that cooperates with the first connecting hole 22 and the second connecting hole 23.

[0064] The first connecting hole 22 is distributed on the first inclined portion 11 and the second inclined portion 13, penetrating the edge reinforcing portion 17. The second connecting hole 23 is distributed at the position where the first inclined portion connects to the arc-shaped portion 12. The upper opening of the second connecting hole 23 is located on the upper surface of the lifting beam body 1, and the lower end of the second connecting hole 23 extends from the surface of the lifting beam body 1 to the bottom surface of the lifting beam body 1. That is to say, the end face of the lower opening of the second connecting hole 23 is flush with the bottom surface of the lifting beam body 1.

[0065] The first cavity 14, the second cavity 15, and the third cavity 16 are provided with multiple reinforcing ribs 24 extending laterally (in the direction of the extension of the center line YY) and longitudinally (in the direction of the extension of the center line XX) along the main body of the lifting beam.

[0066] Functions and effects of the embodiments

[0067] The suspension device provided in this embodiment has a long, narrow suspension beam body. The upper surface of the suspension beam body has a first inclined portion and a second inclined portion extending at an angle, as well as an arc-shaped portion connecting the two first inclined portions. That is, the suspension beam body is streamlined in shape. The lug mounting holes and the power mounting holes pass through the arc-shaped portion and are symmetrical with respect to the center line of the width direction of the suspension beam body. The lugs are installed in the corresponding lug mounting holes, and the power socket is installed in the power mounting holes. Therefore, the overall surface structure of the suspension beam device is symmetrical, and the transition is smooth and beautiful. It not only meets the requirements of the aircraft's aerodynamic shape, but also greatly reduces the aerodynamic drag at the mechanical interface of the aircraft pylon.

[0068] Furthermore, the suspension device in this embodiment integrates multiple functions such as power supply structure, diagonal support, and placement point column, achieving a high degree of integration. Compared with the traditional two spreader beams, the suspension device in this embodiment is a one-piece structure, eliminating the need for complicated assembly and ensuring assembly accuracy through simple installation.

[0069] In addition, the inclined surface of the hoisting device, namely the first inclined surface, has the same curvature as the inclined surface of the top of the cabin, so as to achieve a smooth transition between the hoisting device and the surface of the cabin, resulting in a significant rectification effect.

[0070] In addition, the main body of the suspension beam is made of 7050-T7451 high-strength aluminum alloy, which makes the suspension device highly accurate in assembly, has high rigidity and strength, and is also lightweight, reducing the weight carried by the aircraft.

[0071] In addition, the bottom of the lifting beam body is provided with a first cavity, a second cavity and a third cavity. Diagonal supports are provided between the first cavity and the second cavity and between the second cavity and the third cavity. Reinforcing ribs are provided in the first cavity, the second cavity and the third cavity. Edge reinforcements are provided around the lifting beam body to enhance the strength of the lifting beam body. While reducing the weight of the lifting beam body, the strength of the lifting beam body is increased, which means the strength of the lifting device is increased so that it can meet the needs of lifting different cabins.

[0072] In addition, the top end face of the lug mounting hole is parallel to the bottom surface of the lifting beam body, which facilitates the stable installation of the lug seat and lug.

[0073] The above embodiments are only used to illustrate specific implementations of the present invention, and the present invention is not limited to the scope of the description of the above embodiments.

[0074] In other embodiments, the position of the deployment point column can be adjusted according to different aircraft pylons to improve the versatility of the sling device.
