Description

Technical Field

[0001] This invention relates to the field of spacecraft technology, and more specifically, to a flexible solar array deployment test device and test method. Background Technology

[0002] In the aerospace field, the deployment technology of large flexible solar arrays is one of the key aspects ensuring the normal operation of spacecraft. As the main energy supply device for spacecraft, the reliability and accuracy of the solar array's deployment directly affect the success of space missions. Currently, deployment tests of large flexible solar arrays are typically conducted using a step-by-step verification approach. Specifically, one-dimensional deployment verifies whether the solar array's lifting mechanism can extend normally within a specialized deployment system. After the one-dimensional deployment is completed, a two-dimensional deployment test is conducted using a different deployment system to verify whether the solar array can deploy normally.

[0003] However, existing step-by-step verification methods cannot achieve continuous deployment of the solar array, meaning that the actual on-orbit deployment conditions cannot be fully simulated during testing. Since on-orbit deployment is a continuous process, while ground testing divides it into two independent steps, the lack of continuity can lead to jamming, incomplete deployment, or other mechanical failures. Furthermore, the step-by-step verification method requires replacing the deployment system, potentially introducing additional errors and risks. Summary of the Invention

[0022] With the increasing energy demands of satellites, large flexible solar panels with high retraction ratios, high power, and small size have been rapidly developed. These solar panels are small when folded but have a large area when deployed, providing massive energy support for the satellite. However, an excessively large deployed area may obstruct the field of view of other satellite components such as antennas, cameras, and other payloads. Therefore, some satellites have incorporated lifting mechanisms into their solar panels. These mechanisms can elevate the entire solar panel to a certain height, thus avoiding obstruction from other satellite components, and then release the deployment mechanism to unfold the solar blanket assembly. Typically, the lifting direction of the lifting mechanism is perpendicular to the satellite's dashboard, while the deployment direction of the solar blanket assembly is parallel to the satellite's dashboard; the two are perpendicularly intersecting in space.

[0023] To ensure the proper functioning of the solar array after satellite launch, it is crucial to achieve one-dimensional and two-dimensional deployment with zero-gravity unloading on the ground. Currently, deployment tests of large flexible solar arrays are generally conducted using a step-by-step verification approach. One-dimensional deployment verifies the proper extension of the solar array's lifting mechanism within a specialized deployment system. After one-dimensional deployment is completed, a two-dimensional deployment test is performed using a different deployment system to verify the solar array's ability to deploy normally.

[0024] However, the existing step-by-step verification method has significant drawbacks. It cannot achieve continuous deployment of the solar array, resulting in an inability to fully simulate the actual on-orbit deployment conditions during testing. This lack of continuity may lead to jamming, incomplete deployment, or other mechanical failures. Furthermore, the step-by-step verification method requires replacing the deployment system, which not only increases operational complexity but may also introduce additional errors and risks.

[0025] To address the aforementioned problems, an embodiment of the present invention provides a flexible solar array deployment test device, comprising a one-dimensional deployment and unloading mechanism 100 and a two-dimensional deployment and unloading mechanism 200. The one-dimensional deployment and unloading mechanism 100 includes a transverse guide rail 101, a first air-bearing slider 102, and a lifting assembly 103. The first air-bearing slider 102 is slidably disposed on the transverse guide rail 101 and configured to air-bear on the surface of the transverse guide rail 101 after ventilation. The first air-bearing slider 102 is configured to be connected to the flexible solar array 900 via the lifting assembly 103. The two-dimensional deployment and unloading mechanism 200 includes a first longitudinal guide rail 201, a second longitudinal guide rail 203, multiple first trolley assemblies 202, and multiple second trolley assemblies 204. 02 includes a second air-bearing slider 2021 and a first connector 2022 connected to the second air-bearing slider 2021. The second air-bearing slider 2021 is slidably disposed on the first longitudinal guide rail 201 and is configured to be air-bearing on the surface of the first longitudinal guide rail 201 after air is introduced. The first connectors 2022 of the plurality of first trolley assemblies 202 are respectively connected to the flexible solar array 900. The second trolley assembly 204 includes a sliding block 2041, a rolling element 2042 and a second connector 2043 connected to the sliding block 2041. The sliding block 2041 is slidably disposed on the second longitudinal guide rail 203 through the rolling element 2042. The second connectors 2043 of the plurality of second trolley assemblies 204 are respectively connected to the flexible solar array 900.

[0026] It should be understood that the extension direction of the first longitudinal guide rail 201 and the extension direction of the second longitudinal guide rail 203 are parallel to each other; the extension direction of the transverse guide rail 101 is perpendicular to the extension direction of the first longitudinal guide rail 201 and the extension direction of the second longitudinal guide rail 203, respectively.

[0027] Specifically, such as Figure 1 , 2As shown, in the one-dimensional unfolding and unloading mechanism 100, the first air-bearing slider 102 is sleeved on the transverse guide rail 101 and can be slidably disposed on the transverse guide rail 101 along the extension direction of the transverse guide rail 101; the inner wall of the first air-bearing slider 102 is uniformly provided with a plurality of air-bearing holes so that after the air-bearing holes are ventilated, the first air-bearing slider 102 can be air-bearing on the surface of the transverse guide rail 101; at the same time, the first air-bearing slider 102 is connected to the sun blanket assembly 902 of the flexible solar wing 900 through the lifting assembly 103 so as to apply an upward lifting force to the sun blanket assembly 902 in the retracted state during the extension of the lifting mechanism 901 of the flexible solar wing 900.

[0028] In the two-dimensional unfolding unloading mechanism 200, such as Figure 3 , 4 As shown, the first trolley assembly 202 includes a second air-bearing slider 2021 and a first connecting member 2022 connected to the second air-bearing slider 2021. The second air-bearing slider 2021 is sleeved on the first longitudinal guide rail 201 and can slide along the extension direction of the first longitudinal guide rail 201. The inner wall of the second air-bearing slider 2021 is uniformly provided with multiple air-bearing holes so that after air is introduced through the air-bearing holes, the second air-bearing slider 2021 can be air-bearing on the surface of the first longitudinal guide rail 201. The first connecting members 2022 of the multiple first trolley assemblies 202 are respectively connected to multiple sun blanket units of the sun blanket assembly 902 to apply an upward lifting force to the sun blanket assembly 902 during its extension. The unfolding effect of the multiple first trolley assemblies 202 is as follows: Figure 5 As shown; Figure 6 As shown, the second trolley assembly 204 includes a sliding block 2041, a rolling element 2042, and a second connecting element 2043 connected to the sliding block 2041. The sliding block 2041 is hooked onto the second longitudinal guide rail 203 and can slide along the extension direction of the second longitudinal guide rail 203. The rolling element 2042 is a roller, and a roller is provided at the hook point between the sliding block 2041 and the second longitudinal guide rail 203 to reduce sliding friction. The second connecting elements 2043 of the multiple second trolley assemblies 204 are respectively connected to multiple deployment mechanisms of the flexible solar panel 900 to apply an upward lifting force to the deployment mechanism during the extension of the solar blanket assembly 902.

[0029] In this optional embodiment, during the flexible solar wing 900 deployment test, when the flexible solar wing 900 needs to be deployed in one dimension, the first air-bearing slider 102 of the one-dimensional deployment unloading mechanism 100 is connected to the flexible solar wing 900 through the lifting assembly 103. After the first air-bearing slider 102 is ventilated, it can be air-bearing on the surface of the transverse guide rail 101. During the extension of the flexible solar wing 900, it can apply an upward lifting force to the flexible solar wing 900 and reduce the sliding friction, thereby unloading the weight of the flexible solar wing 900.

[0030] When the flexible solar panel 900 needs to be deployed in two dimensions, the multiple first trolley assemblies 202 of the two-dimensional deployment unloading mechanism 200 can be connected to the solar blanket assembly 902 respectively through the first connector 2022. After the multiple second air-bearing sliders 2021 are ventilated, the second air-bearing sliders 2021 can be air-bearing on the surface of the first longitudinal guide rail 201, which can apply an upward lifting force to the flexible solar panel 900 and reduce the sliding friction, thereby unloading the weight of the solar blanket assembly 902. At the same time, the multiple second trolley assemblies 204 can be connected to the multiple deployment mechanisms of the flexible solar panel 900 respectively through the second connector 2043, and the sliding block 2041 can be slidably disposed on the second longitudinal guide rail 203 through the rolling element 2042, so that an upward lifting force can be applied during the deployment of the flexible solar panel 900.

[0031] In summary, the flexible solar array deployment test device integrates a one-dimensional deployment and unloading mechanism 100 and a two-dimensional deployment and unloading mechanism 200, which can realize continuous verification of the flexible solar array 900 in the one-dimensional and two-dimensional deployment process, thereby ensuring the reliability and safety of the flexible solar array 900 deployment.

[0032] Optionally, the lifting assembly 103 includes a first rope 1031, a lifting device 1032, and a first counterweight 1033; one end of the transverse guide rail 101 is rotatably connected to a first pulley 1011; a second pulley 1021 and a third pulley 1022 are rotatably connected to the first air-bearing slider 102; a fourth pulley 1034 is rotatably connected to the lifting device 1032; one end of the first rope 1031 passes over the first pulley 1011 and is connected to the first counterweight 1033, and the other end of the first rope 1031 passes over the second pulley 1021, the fourth pulley 1034, and the third pulley 1022 in sequence and is connected to the other end of the transverse guide rail 101; the lifting device 1032 is configured to be connected to the flexible solar array 900.

[0033] Specifically, such as Figure 2As shown, a first pulley 1011 is rotatably connected to the bottom of one end of the transverse guide rail 101 along its length; a second pulley 1021 and a third pulley 1022 are rotatably connected to the bottom of the first air-bearing slider 102, and the second pulley 1021 and the third pulley 1022 are distributed sequentially along the extension direction of the transverse guide rail 101; a fourth pulley 1034 is rotatably connected to the lifting device 1032, and is connected to the lifting ring on the sun blanket assembly 902 of the flexible solar wing 900 through a hook; one end of the first rope 1031 passes around the first pulley 1011 and is connected to the first counterweight 1033, and the other end of the first rope 1031 passes around the second pulley 1021, the fourth pulley 1034, and the third pulley 1022 in sequence and is connected to the other end of the transverse guide rail 101; the lifting device 1032 is configured to be connected to the sun blanket assembly 902.

[0034] In this optional embodiment, during the one-dimensional deployment of the flexible solar panel 900, the center of gravity of the solar blanket assembly 902 changes direction during the extension of the lifting mechanism 901, leading to uneven force distribution and potentially causing shaking or instability. This embodiment employs a pulley system with a counterweight 1033 for unloading. By properly configuring the counterweight 1033, the unbalanced torque caused by the change in the center of gravity can be counteracted in real time, achieving dynamic balance of the center of gravity. Simultaneously, the pulley system's layout ensures even force distribution within the ropes, preventing damage to the solar blanket assembly 902 or connecting components due to excessive localized force.

[0035] Optionally, the first longitudinal guide rail 201 has at least one pair, and the pair of first longitudinal guide rails 201 are arranged parallel and spaced apart; the first connector 2022 of a single first trolley assembly 202 is slidably disposed on the pair of first longitudinal guide rails 201 through two second air-bearing sliders 2021; the first connector 2022 is a rod-shaped member, and the first connector 2022 of a portion of the first trolley assembly 202 is inclined downward from one end to the other end of the first longitudinal guide rail 201, forming a first trolley group 205, and the lifting ends of multiple first connectors 2022 in the first trolley group 205 are arranged sequentially in the vertical direction; the first connectors 2022 of the remaining first trolley assembly 202 are inclined upward from one end to the other end of the first longitudinal guide rail 201, forming a second trolley group 206, and the lifting ends of multiple first connectors 2022 in the second trolley group 206 are arranged sequentially in the vertical direction.

[0036] Specifically, the number of the first longitudinal guide rails 201 is an even number, such as two, four, or six. There is no restriction here; it depends on the actual needs. Figure 4As shown, there are two pairs of first longitudinal guide rails 201. In each pair of first longitudinal guide rails 201, the two first longitudinal guide rails 201 are parallel and spaced apart in the vertical direction. In a single first trolley assembly 202, the first connecting member 2022 is a rod-shaped member. The first connecting member 2022 is connected to two second air-bearing sliders 2021 respectively, and is slidably disposed on a pair of first longitudinal guide rails 201 through the two second air-bearing sliders 2021.

[0037] On each pair of first longitudinal guide rails 201, the first connecting members 2022 of eleven first trolley assemblies 202 are inclined downward at 45 degrees from one end to the other along the length of the first longitudinal guide rail 201, forming a first trolley group 205. The lifting ends of the multiple first connecting members 2022 in the first trolley group 205 are arranged vertically in sequence and connected to the lifting rings on the sun blanket unit of the sun blanket assembly 902 via ropes. The first connecting members 2022 of the eleven first trolley assemblies 202 are inclined upward at 45 degrees from one end to the other along the length of the first longitudinal guide rail 201, forming a second trolley group 206. The lifting ends of the multiple first connecting members 2022 in the second trolley group 206 are arranged vertically in sequence and connected to the lifting rings on the sun blanket unit of the sun blanket assembly 902 via ropes. That is, as... Figure 4 As shown, the first pulley group 205 and the second pulley group 206 are generally similar to a V shape.

[0038] In this optional embodiment, since the first connector 2022 of a single first trolley assembly 202 is slidably disposed on a pair of parallel and spaced first longitudinal guide rails 201 by two second air-bearing sliders 2021, this layout allows the first connector 2022 to slide smoothly on the guide rails while maintaining good guidance and stability.

[0039] The first connecting members 2022 of the first trolley assembly 205 are inclined downwards from one end of the first longitudinal guide rail 201 to the other end, while the first connecting members 2022 of the second trolley assembly 206 are inclined upwards from one end of the first longitudinal guide rail 201 to the other end. Because the first connecting members 2022 are inclined, their structure can better distribute the torque when subjected to force, preventing jamming caused by excessive torque generated during the unfolding of the sun blanket due to the excessive length of the trolley connecting frame.

[0040] Meanwhile, the inclination directions of the first connecting members 2022 in the first trolley group 205 and the second trolley group 206 are opposite, which can achieve spatial misalignment, allowing multiple first trolley components 202 to be compatiblely arranged within a limited space. This arrangement avoids mutual interference between the first trolley components 202 and improves the space utilization of the entire system. Moreover, if the lifting points of all the first connecting members 2022 are arranged along the extension direction of the first longitudinal guide rail 201, some of the first connecting members 2022 will be very long, prone to deformation, and not conducive to deployment. However, if the lifting points of the first connecting members 2022 in the first trolley group 205 or the first connecting members 2022 in the second trolley group 206 are arranged in the vertical direction, the length of the first connecting members 2022 can be effectively reduced, the rigidity of the first connecting members 2022 can be increased, and thus deformation can be significantly reduced.

[0041] Optionally, when a pair of first longitudinal guide rails 201 have multiple sets of first trolley groups 205 and / or multiple sets of second trolley groups 206, the first trolley groups 205 and the second trolley groups 206 are staggered along the extension direction of the first longitudinal guide rails 201.

[0042] In one embodiment, a pair of first longitudinal guide rails 201 have multiple sets of first trolley groups 205 and multiple sets of second trolley groups 206, which are staggered along the extending direction of the first longitudinal guide rails 201. For example, two first trolley groups 205 and two second trolley groups 206 are staggered along the extending direction of the first longitudinal guide rails 201.

[0043] In this optional embodiment, when the number of sun blanket units in the sun blanket assembly 902 is large, the space occupancy rate of the entire device in the vertical direction and the sliding direction of the first longitudinal guide rail 201 can be balanced by increasing the number of the first pulley group 205 and the second pulley group 206 and adjusting the arrangement of the first pulley group 205 and the second pulley group 206.

[0044] Optionally, when there are multiple pairs of first longitudinal guide rails 201, the multiple pairs of first longitudinal guide rails 201 are arranged sequentially in the vertical direction, and the lifting ends of multiple first connectors 2022 in the first trolley group 205 on the multiple pairs of first longitudinal guide rails 201 are arranged sequentially in the vertical direction; the lifting ends of multiple first connectors 2022 in the second trolley group 206 on the multiple pairs of transverse guide rails 101 are arranged sequentially in the vertical direction.

[0045] In one implementation, such as Figure 4As shown, the first longitudinal guide rail 201 has two pairs, and the two pairs of first longitudinal guide rails 201 are arranged in sequence along the vertical direction. The first trolley group 205 of the two pairs of first longitudinal guide rails 201 is provided with eleven first connectors 2022, and the lifting ends of the twenty-two first connectors 2022 are arranged in sequence along the vertical direction. The second trolley group 206 of the two pairs of second longitudinal guide rails 203 is also provided with eleven first connectors 2022, and the lifting ends of the twenty-two first connectors 2022 are also arranged in sequence along the vertical direction.

[0046] In this optional embodiment, when the number of sun blanket units in the sun blanket assembly 902 is large, the space occupancy rate of the entire device in the vertical direction and the sliding direction of the first longitudinal guide rail 201 can be balanced by increasing the number of the first longitudinal guide rail 201 and the arrangement of the first trolley group 205 and the second trolley group 206 on the multiple pairs of first longitudinal guide rail 201.

[0047] Optionally, the first trolley assembly 202 further includes a swing arm 2023 and a second rope 2024; the swing arm 2023 is rotatably disposed at the lifting end of the first connector 2022, and the rotation axis of the swing arm 2023 is parallel to the vertical direction; one end of the second rope 2024 is connected to the swing arm 2023, and the other end is configured to be connected to the flexible solar array 900.

[0048] Specifically, such as Figure 3 As shown, the lower end of the first connector 2022 is the lifting end; the swing arm 2023 is horizontally arranged at the lower end of the first connector 2022 and can rotate relative to the first connector 2022, and the rotation axis of the swing arm 2023 is parallel to the vertical direction; the upper end of the second rope 2024 is tied and fixed to the swing arm 2023, and the lower end is tied and fixed to the lifting ring or hole structure of the sun blanket unit of the sun blanket assembly 902.

[0049] In this optional embodiment, during the unfolding of the sun blanket assembly 902, as the first trolley assembly 202 slides along the first longitudinal guide rail 201, the swing arm 2023 can adaptively rotate horizontally according to the actual unfolding trajectory of the sun blanket assembly 902. This structural design effectively avoids excessive stretching or compression of the sun blanket due to trajectory deviation during unfolding, preventing tearing or damage to the sun blanket, improving the reliability and safety of the flexible sun wing 900 unfolding, and ensuring that the flexible sun wing 900 can unfold smoothly and completely.

[0050] Optionally, the flexible solar array deployment test device further includes an air duct structure 500 and an air duct traction mechanism 300; multiple second air-bearing sliders 2021 are respectively connected to an air source through corresponding air duct structures 500; the air duct traction mechanism 300 includes a slide rail 301, a drive motor 302, a fourth pulley 1034, a fifth pulley 303, a flexible transmission component 305, and multiple moving blocks 306; the slide rail 301 is connected to the fifth pulley 303 and the sixth pulley 304 at both ends along its length; multiple moving blocks 306 are slidably disposed on the slide rail 301 along its length and are connected to the flexible transmission component 305 and at least one air duct structure 500; the drive motor 302 is drivenly connected to the fifth pulley 303 or the sixth pulley 304; the flexible transmission component 305 is annular, and the fifth pulley 303 and the sixth pulley 304 are located at both ends inside the flexible transmission component 305 and are connected by transmission through the flexible transmission component 305.

[0051] Specifically, the second air-float slider 2021 is connected to the air source through a corresponding air pipe structure 500; such as Figure 7 , 8 As shown, in the tracheal traction mechanism 300, a fifth pulley 303 is rotatably connected to the side face of one end of the slide rail 301 along its length, and a sixth pulley 304 is rotatably connected to the side face of the other end; the slide rail 301 is provided with a groove extending along the length of the slide rail 301, and the moving block 306 is provided with a slider, which is slidably disposed in the groove; the moving block 306 is connected to the flexible transmission component 305 and at least one tracheal structure 500; the drive motor 302 is drivenly connected to the fifth pulley 303; the flexible transmission component 305 is a belt or rope, and its whole is ring-shaped. The two ends inside the flexible transmission component 305 are respectively tensioned to the fifth pulley 303 and the sixth pulley 304, and the tensioning of the fifth pulley 303 and the sixth pulley 304 can be transmitted through the flexible transmission component 305.

[0052] In this optional embodiment, when the drive motor 302 drives the fifth pulley 303 or the sixth pulley 304 to rotate, the flexible transmission component 305 will drive multiple moving blocks 306 to move along the slide rail 301. This design allows the air tube structure 500 to adjust the position and tension of the air tube by moving the moving blocks 306 as it moves along the deployment direction of the sun blanket assembly 902 following the second air float slider 2021. This avoids excessive resistance from the air tube to the deployment mechanism, ensuring the smoothness and reliability of the deployment process, while reducing deployment failures that may be caused by air tube pulling, and improving the stability and deployment efficiency of the entire system.

[0053] Optionally, the flexible solar array deployment test device also includes a frame structure 400, on which a transverse guide rail 101, a first longitudinal guide rail 201, and a second longitudinal guide rail 203 are all mounted, with the first longitudinal guide rail 201 located above the transverse guide rail 101 and the second longitudinal guide rail 203; the second longitudinal guide rail 203 is located on one side of the transverse guide rail 101 along the width direction.

[0054] Specifically, the frame structure 400 serves as the installation platform for the entire device, which can be suspended in the air via support rods or tie rods; for example... Figure 1 As shown, there are multiple first longitudinal guide rails 201, which are disposed inside the frame structure 400; the transverse guide rail 101 and the second longitudinal guide rail 203 are both located at the bottom of the frame structure 400, and the second longitudinal guide rail 203 is located on one side of the transverse guide rail 101 along the width direction.

[0055] In this optional embodiment, the frame structure 400 provides stable support for each transverse guide rail 101, the first longitudinal guide rail 201, and the second longitudinal guide rail 203, ensuring the stability of the components on the transverse guide rail 101, the first longitudinal guide rail 201, and the second longitudinal guide rail 203 during operation. The high position of the first longitudinal guide rail 201 causes it to be spatially misaligned with the transverse guide rail 101 and the second longitudinal guide rail 203, avoiding mutual interference and ensuring the independent operation and smooth sliding of the components on each guide rail.

[0056] Optionally, the flexible solar array deployment test device also includes a height adjustment mechanism 600, and the second longitudinal guide rail 203 is connected to the frame structure 400 through the height adjustment structure.

[0057] Specifically, such as Figure 6 As shown, the height adjustment mechanism 600 includes a threaded rod 601, a first nut 602, and a second nut 603. One end of the threaded rod 601 is connected to the frame structure 400, and the other end extends vertically downward. The second longitudinal guide rail 203 is sleeved on the threaded rod 601 and is located between the first nut 602 and the second nut 603.

[0058] In this optional embodiment, the position of the second longitudinal guide rail 203 relative to the frame structure 400 can be precisely controlled by the height adjustment mechanism 600, thereby optimizing the spatial layout and functional configuration of the entire system.

[0059] In other embodiments, the height adjustment mechanism 600 can be a telescopic cylinder, with the fixed end of the telescopic cylinder connected to the frame structure 400 and the telescopic end of the telescopic cylinder connected to the second longitudinal guide rail 203.

[0060] Optionally, the flexible solar array deployment test apparatus also includes a simulation wall 700, which is configured to be connected to the flexible solar array 900.

[0061] Specifically, such as Figure 9 As shown, the simulation wall 700 has a vertically mounted mobile trolley 800, which is located below the flexible solar wing deployment test device. It is used to detachably connect to the lifting mechanism 901 of the flexible solar wing 900. The detachment methods of the two include, but are not limited to, high-strength screw connection or pin connection.

[0062] In this optional embodiment, since the simulation wall 700 is configured to connect to the lifting mechanism 901 of the flexible solar array 900, this design allows the simulation wall 700 to effectively bear the weight and stress of the flexible solar array 900 during the extension process of the lifting mechanism 901. By connecting the lifting mechanism 901 to the simulation wall 700, the weight of the flexible solar array 900 can be evenly transferred to the simulation wall 700, ensuring that the flexible solar array 900 remains stable during lifting and deployment, reducing mechanical failures that may be caused by vibration or shaking.

[0063] The test method of the flexible solar array deployment test device in this embodiment of the invention uses the flexible solar array deployment test device as described above, such as... Figure 10 As shown, the test methods include: S100, Connect the lifting component 103 of the one-dimensional unfolding and unloading mechanism 100 to the sun blanket component 902 of the flexible solar wing 900 in the retracted state. In step S100, the upper surface of the sun blanket assembly 902 is provided with a lifting ring or hook and other lifting fittings. The lifting device 1032 of the lifting assembly 103 cooperates with the lifting ring or hook and other lifting fittings to lift the sun blanket assembly 902.

[0064] S200, the first air-bearing slider 102 of the one-dimensional unfolding and unloading mechanism 100 is ventilated so that the first air-bearing slider 102 is air-bearing on the surface of the transverse guide rail 101 of the one-dimensional unfolding and unloading mechanism 100. In step S200, the first air-bearing slider 102 is connected to the air source through an air pipe. When the air source is controlled to work, it can deliver gas to the first air-bearing slider 102, thereby forming a thin air film between the first air-bearing slider 102 and the transverse guide rail 101 to reduce the friction between the first air-bearing slider 102 and the transverse guide rail 101.

[0065] S300, the lifting mechanism 901 of the flexible solar panel 900 is operated until the solar blanket assembly 902 in the retracted state moves to directly below the first longitudinal guide rail 201 of the two-dimensional unfolding and unloading mechanism 200. In step S300, after the lifting mechanism 901 of the flexible solar wing 900 extends into place, the solar blanket assembly 902, which is in a retracted state, needs to move to directly below the first longitudinal guide rail 201 of the two-dimensional unfolding and unloading mechanism 200, so as to facilitate the subsequent connection of the first connector 2022 and the second connector 2043 of the two-dimensional unfolding and unloading mechanism 200 with the solar blanket assembly 902.

[0066] S400, the first connecting pieces 2022 of the plurality of first trolley assemblies 202 of the two-dimensional unfolding and unloading mechanism 200 are respectively connected to the sun blanket assembly 902, and the second connecting pieces 2043 of the plurality of second trolley assemblies 204 of the two-dimensional unfolding and unloading mechanism 200 are respectively connected to the plurality of unfolding mechanisms of the flexible sun wing 900. In step S400, the sun blanket assembly 902 includes multiple sun blanket units, and the base plate of each sun blanket unit is provided with lifting fittings such as lifting rings or hooks. The first connector 2022 and the second connector are tied and fixed to the lifting fittings such as lifting rings or hooks by ropes, thereby lifting the sun blanket assembly 902.

[0067] S500, control the second air-bearing slider 2021 of the multiple first trolley assemblies 202 to ventilate, so that the second air-bearing slider 2021 is air-bearing on the surface of the first longitudinal guide rail 201; In step S500, the second air-float slider 2021 is connected to the air source through an air pipe. When the air source is controlled to work, it can deliver gas to the second air-float slider 2021, thereby forming a thin air film between the second air-float slider 2021 and the first longitudinal guide rail 201 to reduce the friction between the second air-float slider 2021 and the first longitudinal guide rail 201.

[0068] Furthermore, since the unfolded length of the sun blanket assembly 902 is relatively long, in order to reduce the problem of the air tube pulling causing the unfolding to be not smooth, the air tube traction mechanism 300 needs to be activated at this time, so as to make the air tube follow the unfolding.

[0069] S600 controls the deployment mechanism of the flexible solar panel 900 until the solar blanket assembly 902 is deployed in place.

[0070] The test method of the flexible solar wing deployment test device in this embodiment has the same beneficial effects as the above-described flexible solar wing deployment test device compared with related technologies, so it will not be described again here.

[0071] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
