Description

Technical Field

[0001] This application relates to the field of aerospace equipment technology, and further to a fairing assembly method and apparatus, and a fairing. Background Technology

[0002] The fairing is a critical component of spacecraft such as satellites, launch vehicles, and space shuttles, primarily used to protect satellites and other payloads from harmful environments including aerodynamic forces, aerodynamic heating, and acoustic vibration. However, existing fairing assembly methods have certain limitations. Typically, the two fairing halves need to be hoisted separately to their designated positions within a vibration tower to complete the assembly operation. Due to the relatively confined space inside the vibration tower, this process requires extremely high hoisting precision, which not only increases the complexity of the operation but also reduces the ease of fairing assembly to some extent. Summary of the Invention

[0003] To address the aforementioned technical problems, this application provides a fairing assembly method and apparatus, as well as a fairing, which reduces operational complexity and improves the convenience of fairing assembly.

[0004] In a first aspect, this application provides a fairing assembly method. The fairing includes a first rectifier half-fairing and a second rectifier half-fairing, both of which include multiple steering wheels. The fairing assembly method includes: acquiring target distances between each steering wheel and the center of the satellite's bottom circle using sensors on each steering wheel; adjusting the target distance of one steering wheel in the first and / or second rectifier half-fairing to the preset distance when the target distance of that steering wheel is not met, so that the center of the first and / or second rectifier half-fairing coincides with the center of the satellite's bottom circle; and controlling the first and / or second rectifier half-fairing to align with the target distance of the satellite's bottom circle when the teeth on the first and / or second rectifier half-fairing are not aligned with the teeth holes on the satellite. The second rectifier half-cover rotates in place to align the teeth on the first and / or second rectifier half-cover with the tooth holes on the satellite; when the first and second rectifier half-covers are not aligned, the height of the rudder wheel in the first and / or second rectifier half-covers is adjusted to align the first and second rectifier half-covers; when the first and second rectifier half-covers meet preset conditions, the first and second rectifier half-covers are joined together; the preset conditions include the center of the first and second rectifier half-covers coinciding with the bottom center of the satellite, the teeth on the first and second rectifier half-covers aligning with the tooth holes on the satellite, and the first and second rectifier half-covers being aligned.

[0005] The fairing assembly method described above, through precise sensor measurements and a flexible adjustment mechanism, ensures that the first and second fairing halves are accurately aligned with the bottom center of the satellite, the teeth are aligned with the teeth holes, and the two halves are aligned with themselves. This achieves efficient and accurate fairing assembly, reduces operational complexity, and improves the convenience of fairing assembly.

[0006] In one implementation, the multiple control wheels include a first control wheel, a second control wheel, and a third control wheel. When the target distance of one control wheel in the first and / or second fairing does not reach the preset distance, the target distance of the control wheel is adjusted to the preset distance. Specifically, this includes: taking the horizontal distance between the first and second control wheels and the center of the bottom circle of the satellite as the first target distance of the first and second control wheels; when the first target distance between the first and second control wheels of the first and / or second fairing does not reach the preset distance, controlling the first and / or second fairing to execute a lateral movement mode to adjust the first target distance to the preset distance.

[0007] In one implementation, the method further includes: using the vertical distance between the third rudder wheel and the center of the bottom circle of the satellite as the second target distance of the third rudder wheel; when the second target distance of the third rudder wheel of the first and / or second rectifier half-shell does not reach the preset distance, controlling the first and / or second rectifier half-shell to execute the travel mode to adjust the second target distance to the preset distance.

[0008] The fairing assembly method described above, by precisely measuring and adjusting the first target distances of the first and second rudder wheels and the second target distance of the third rudder wheel, and using lateral and traversal modes to correct the distances in the horizontal and vertical directions respectively, can more comprehensively ensure the precise alignment of the fairing half with the center of the satellite's bottom circle. This multi-dimensional precision adjustment mechanism not only improves the assembly accuracy of the fairing and the satellite but also effectively reduces assembly problems caused by positional deviations.

[0009] In one implementation, when the teeth on the first and / or second rectifier half-cover are not aligned with the tooth holes on the satellite, the first and / or second rectifier half-cover are controlled to rotate in place. Specifically, this includes: obtaining the deviation angle between the teeth on the first and / or second rectifier half-cover and the tooth holes on the satellite; and controlling the first and / or second rectifier half-cover to rotate clockwise or counterclockwise around their respective centers according to the deviation angle.

[0010] In one implementation, when the first and second rectifier halves are not aligned, the height of the steering wheels in the first and / or second rectifier halves is adjusted, specifically including: determining the height of all steering wheels in the first and second rectifier halves; when there is a height deviation between a steering wheel in the first rectifier halves and the corresponding steering wheel in the second rectifier halves, the height of the steering wheel and / or the corresponding steering wheel is adjusted.

[0011] The above fairing assembly method achieves precise alignment by accurately measuring the deviation angle between the teeth and the tooth holes, and controlling the fairing half to rotate clockwise or counterclockwise around the center based on this deviation angle. Simultaneously, by determining the height of all steering wheels on both the first and second fairing halves, and adjusting the height of the steering wheels when height deviations exist, accurate alignment of the two fairing halves is ensured. These measures significantly improve the accuracy and reliability of fairing assembly, reducing assembly errors and potential risks caused by inaccurate alignment.

[0012] Secondly, this application also provides a fairing assembly device. The fairing includes a first rectifier half-fairing and a second rectifier half-fairing, each of which includes multiple steering wheels. The fairing assembly device includes: a data acquisition module configured to acquire target distances between each steering wheel and the center of the satellite's bottom circle via sensors on each steering wheel; and an adjustment module configured to: adjust the target distance of one steering wheel in the first and / or second rectifier half-fairing to the preset distance when the target distance of one steering wheel is not reached, so that the center of the first and / or second rectifier half-fairing coincides with the center of the satellite's bottom circle; and control the alignment of the teeth on the first and / or second rectifier half-fairing with the teeth holes on the satellite when the teeth on the first and / or second rectifier half-fairing are not aligned with the teeth holes on the satellite. The first and / or second rectifier half-cover rotate in place to align the teeth on the first and / or second rectifier half-cover with the tooth holes on the satellite; when the first and second rectifier half-covers are not aligned, the height of the rudder wheel in the first and / or second rectifier half-covers is adjusted to align the first and second rectifier half-covers; the cover-up module is configured to close the first and second rectifier half-covers when the first and second rectifier half-covers meet preset conditions; the preset conditions include the center of the first and second rectifier half-covers coinciding with the bottom center of the satellite, the teeth on the first and second rectifier half-covers aligning with the tooth holes on the satellite, and the first and second rectifier half-covers being aligned.

[0013] In one implementation, the plurality of control wheels includes a first control wheel, a second control wheel, and a third control wheel. The adjustment module is configured to: take the horizontal distance between the first control wheel and the second control wheel and the center of the bottom circle of the satellite as the first target distance between the first control wheel and the second control wheel; when the first target distance between the first control wheel and the second control wheel of the first and / or second rectifier half-shaft does not reach the first preset distance, control the first and / or second rectifier half-shaft to execute a lateral movement mode to adjust the first target distance to the first preset distance.

[0014] In one implementation, the adjustment module is configured to: take the vertical distance between the third rudder wheel and the center of the bottom circle of the satellite as the second target distance of the third rudder wheel; when the second target distance of the third rudder wheel of the first and / or second rectifier half-shell does not reach the second preset distance, control the first and / or second rectifier half-shell to execute the travel mode to adjust the second target distance to the second preset distance.

[0015] In one implementation, the adjustment module is configured to: obtain the deviation angle between the serrations on the first and / or second rectifier half and the serration holes on the satellite; and control the first and / or second rectifier half to rotate clockwise or counterclockwise around their respective centers based on the deviation angle.

[0016] Thirdly, this application also provides a fairing configured to be closed by any of the fairing closing methods described above.

[0017] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0018] 1. Through precise sensor measurements and flexible adjustment mechanisms, the first and second fairings are ensured to be precisely aligned with the bottom center of the satellite, with the ferrules aligned with the ferrule holes, and with the two fairings themselves. This enables efficient and accurate fairing assembly, reduces operational complexity, and improves the convenience of fairing assembly.

[0019] 2. By precisely measuring and adjusting the first target distances of the first and second rudder wheels and the second target distance of the third rudder wheel, and by using lateral and traversal modes to correct the distances in the horizontal and vertical directions respectively, the precise alignment of the fairing half with the center of the satellite's bottom can be more comprehensively ensured. This multi-dimensional precision adjustment mechanism not only improves the assembly accuracy of the fairing and the satellite but also effectively reduces assembly problems caused by positional deviations.

[0020] 3. By precisely measuring the deviation angle between the ferrule and the ferrule hole, and controlling the rotation of the fairing half around the center clockwise or counterclockwise according to this deviation angle, precise alignment of the ferrule and the ferrule hole was achieved. Simultaneously, by determining the height of all the steering wheels of the first and second fairing halves, and adjusting the height of the steering wheels when height deviations exist, accurate alignment of the two fairing halves was ensured. These measures significantly improved the accuracy and reliability of fairing assembly, reducing assembly errors and potential risks caused by inaccurate alignment. Attached Figure Description

[0021] The preferred embodiments will now be described in a clear and easy-to-understand manner, in conjunction with the accompanying drawings, to further explain the above-mentioned characteristics, technical features, advantages, and implementation methods of the present invention.

[0023] Figure 2 A structural block diagram of a fairing assembly device provided in an embodiment of this application is shown. Detailed Implementation

[0024] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0025] To keep the drawings concise, each figure only schematically shows the parts relevant to the invention, and these do not represent the actual structure of the product. Furthermore, to facilitate understanding, in some figures, only one of components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0026] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0027] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0028] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

[0030] The fairing is a critical component of space shuttles, satellites, and launch vehicles, primarily used to protect satellites and other payloads from harmful environments such as aerodynamic forces, aerodynamic heating, and acoustic vibration. Through its unique design and structure, it provides a relatively stable internal environment for satellites and other equipment, ensuring their safety and stability during launch and flight. In practice, fairing assembly typically begins by hoisting one fairing half without its support frame into the vibration tower, aligning its inner wall with the outer wall of the simulated spacecraft that has already been docked. This fairing half is then rotated to its predetermined installation position. After installation, the other fairing half with its support frame is hoisted into the vibration tower following the same process, aligning its mating surfaces with the other fairing half, and finally completing the assembly. This process is constrained by the internal space of the vibration tower, thus requiring high hoisting precision. This not only increases the complexity of the operation but also reduces the ease of fairing assembly to some extent.

[0031] Therefore, this application proposes a fairing assembly scheme, which adjusts the steering wheels of the two fairing halves by setting multiple working modes during the assembly process, so that the two fairing halves can be successfully assembled, thereby reducing the complexity of operation and improving the convenience of fairing assembly.

[0032] The following explanation is based on the accompanying diagram:

[0033] Reference Appendix Figure 1 The diagram illustrates a flowchart of a rectification and shielding method provided in an embodiment of this application. Figure 1 As shown, it includes:

[0034] S100 uses sensors on each control wheel to collect the target distance between each control wheel and the center of the satellite's bottom circle.

[0035] S110, when the target distance of one of the rudder wheels in the first and / or second fairing is not at the preset distance, adjust the target distance of the rudder wheel to the preset distance so that the center of the first and / or second fairing coincides with the center of the bottom of the satellite.

[0036] S120, when the teeth on the first and / or second rectifier half-cover are not aligned with the teeth holes on the satellite, control the first and / or second rectifier half-cover to rotate in place so that the teeth on the first and / or second rectifier half-cover are aligned with the teeth holes on the satellite.

[0037] S130, when the first and second rectifier half-covers are not aligned, adjust the height of the steering wheel in the first and / or second rectifier half-covers to align the first and second rectifier half-covers.

[0038] S140, when the first rectifier half-cover and the second rectifier half-cover meet the preset conditions, the first rectifier half-cover and the second rectifier half-cover are combined. The preset conditions include the center of the first rectifier half-cover and the second rectifier half-cover coinciding with the center of the bottom of the satellite, the serrations on the first rectifier half-cover and the second rectifier half-cover aligning with the serration holes on the satellite, and the first rectifier half-cover and the second rectifier half-cover being aligned.

[0039] The fairing may include two fairing halves, such as a first fairing and a second fairing. Each fairing halves are equipped with three control wheels, located on the bottom semicircle of the fairing halves. Specifically, two control wheels are positioned at the two endpoints of the diameter edge of the bottom semicircle (e.g., the first and second control wheels). The third control wheel (e.g., the third control wheel) is positioned on the arc edge of the bottom semicircle, with the line connecting this wheel to the center of the bottom semicircle perpendicular to the diameter edge. Each control wheel is equipped with three motors: a travel motor, a steering motor, and a lifting motor, used to control the wheel's travel, steering, and lifting, respectively. Each control wheel is also equipped with a sensor to acquire the distance between the control wheel and the target center of the satellite's bottom circle (using a satellite as an example, but also applicable to space shuttles, launch vehicles, and other equipment requiring fairings). The sensor may include, but is not limited to, ultrasonic sensors, laser sensors, infrared ranging sensors, radar ranging sensors, etc. This application does not limit the type of sensor.

[0040] The fairing has multiple operating modes, including but not limited to: traveling mode, lateral movement mode, rotation mode, individual lifting mode, and coordinated lifting mode. The traveling mode controls the forward and backward movement of each fairing half (forward movement refers to the fairing half approaching the satellite, and backward movement refers to the fairing half moving away from the satellite). The lateral movement mode controls the left and right movement of each fairing half. The rotation mode controls the clockwise or counterclockwise rotation of each fairing half along its respective bottom center. The individual lifting mode controls the raising or lowering of the fairing half's control wheels, while the coordinated lifting mode controls the raising or lowering of the entire combined fairing after two fairing halves are joined. Each operating mode involves controlling the direction, movement, and lifting / lowering of the control wheels.

[0041] The prerequisites for combining the first and second rectifier halves include: the center of the first and second rectifier halves (referring to the center of the bottom semicircle of each of the first and second rectifier halves) coinciding with the bottom center of the satellite; the serrations on the first and second rectifier halves aligning with the serration holes on the satellite; and the alignment of the first and second rectifier halves.

[0042] If the centers of both the first and second fairings coincide with the center of the satellite's bottom circle, it means that the target distances between all the control wheels of these two fairings and the center of the satellite's bottom circle have reached the preset distance (which can be the radius of the bottom semicircle of the fairing). Conversely, if the target distance of any control wheel does not reach the preset distance, then the center of either the first or second fairing is not coincident with the center of the satellite's bottom circle. Taking the first fairing as an example, if the target distance of any control wheel in the first fairing does not reach the preset distance, then the first fairing can be controlled to start either a travel mode or a lateral movement mode based on the position of that control wheel. For example, if the control wheel is located at any endpoint of the diameter side of the bottom semicircle of the first fairing, the lateral movement mode of the first fairing is activated, thereby controlling the first fairing to move left or right; if the control wheel is located at the arc edge of the bottom semicircle of the first fairing, the travel mode of the first fairing is activated, thereby controlling the first fairing to move forward or backward. Finally, when the target distance of the corresponding steering wheel in the first rectifier half reaches the preset distance, the lateral movement mode or traveling mode of the first rectifier half is stopped. In other cases, such as when the target distance of one steering wheel in the second rectifier half does not reach the preset distance, or when the target distance of one steering wheel in both the first and second rectifier half does not reach the preset distance, or when the target distance of multiple steering wheels in the first and / or second rectifier half does not reach the preset distance, the adjustment process is the same as that of the first rectifier half, and will not be elaborated here.

[0043] Both the first and second fairing halves are equipped with teeth (or U-shaped teeth) that correspond to the U-shaped tooth holes on the satellite. The teeth are located on the base of the lifting mechanism of the middle support leg of the fairing halves, while the tooth holes are located on the satellite support base. When the teeth on the first and / or second fairing halves are not aligned with the tooth holes on the satellite, the rotation mode of the first and / or second fairing halves needs to be activated. This allows the fairing halves to be rotated clockwise or counterclockwise until the teeth on the first and / or second fairing halves are aligned with the tooth holes on the satellite.

[0044] When the first and second fairings are not aligned, this misalignment can refer to horizontal alignment (if horizontally misaligned, then the center of one fairing must not coincide with the bottom center of the satellite) and vertical alignment (here, vertical refers to the direction perpendicular to the entire ground in space). In this case, it is necessary to activate the individual lifting mode of the first and / or second fairings to adjust the height of the control wheels in the first and / or second fairings, so that the first and second fairings are aligned.

[0045] After all preset conditions are met, the first rectifier half-cover and the second rectifier are combined into a cover, and the entire cover is raised or lowered to a preset height using a linkage lifting mode, after which other process steps can be performed.

[0046] The embodiments of this application ensure that the first and second fairings are precisely aligned with the bottom center of the satellite, the teeth are aligned with the teeth holes, and the two fairings themselves through precise sensor measurements and flexible adjustment mechanisms. This achieves efficient and accurate fairing assembly, reduces the complexity of the operation, and improves the convenience of fairing assembly.

[0047] In some embodiments of this application, the plurality of control wheels includes a first control wheel, a second control wheel, and a third control wheel. When the target distance of one control wheel in the first and / or second fairing does not reach a preset distance, the target distance of that control wheel is adjusted to the preset distance. Specifically, this includes: using the horizontal distance between the first and second control wheels and the center of the bottom circle of the satellite as the first target distance between the first and second control wheels; when the first target distance between the first and second control wheels of the first and / or second fairing does not reach the preset distance, controlling the first and / or second fairing to execute a lateral movement mode to adjust the first target distance to the preset distance; and using the vertical distance between the third control wheel and the center of the bottom circle of the satellite as the second target distance of the third control wheel; when the second target distance of the third control wheel of the first and / or second fairing does not reach the preset distance, controlling the first and / or second fairing to execute a traveling mode to adjust the second target distance to the preset distance.

[0048] The horizontal distances (i.e., the horizontal components of the distances between the first and second rudder wheels and the center of the satellite's bottom circle) are taken as the first target distances for the first and second rudder wheels, respectively. The vertical distances (i.e., the vertical components of the distances between the third rudder wheel and the center of the satellite's bottom circle) are taken as the second target distance for the third rudder wheel. Both horizontal and vertical distances refer to distances on the ground.

[0049] The first and second steering wheels influence each other; that is, if the first target distance of the first steering wheel is not reached, the first target distance of the second steering wheel is also not reached. Therefore, when the first target distance between the first and second steering wheels of the first and / or second rectifier half-shells is not reached, the first and / or second rectifier half-shells are controlled to execute a lateral movement mode, causing the first and / or second rectifier half-shells to move left or right until the first target distance between the first and second steering wheels reaches the preset distance.

[0050] When the second target distance of the third steering wheel of the first and / or second rectifier half-shell does not reach the preset distance, the first and / or second rectifier half-shell is controlled to execute the travel mode, so that the first and / or second rectifier half-shell moves forward or backward until the second target distance of the third steering wheel reaches the preset distance.

[0051] This embodiment of the application precisely measures and adjusts the first target distances of the first and second rudder wheels and the second target distance of the third rudder wheel, respectively. It uses lateral and traversal modes to correct the distances in the horizontal and vertical directions, respectively, thus ensuring more comprehensive and accurate alignment between the fairing and the satellite's bottom center. This multi-dimensional precision adjustment mechanism not only improves the assembly accuracy of the fairing and the satellite but also effectively reduces assembly problems caused by positional deviations.

[0052] In some embodiments of this application, when the teeth on the first and / or second rectifier half-cover are not aligned with the tooth holes on the satellite, the first and / or second rectifier half-cover are controlled to rotate in place. Specifically, this includes: obtaining the deviation angle between the teeth on the first and / or second rectifier half-cover and the tooth holes on the satellite; and controlling the first and / or second rectifier half-cover to rotate clockwise or counterclockwise around their respective centers according to the deviation angle.

[0053] In some embodiments of this application, when the first and second rectifier halves are not aligned, the height of the steering wheels in the first and / or second rectifier halves is adjusted, specifically including: determining the height of all steering wheels in the first and second rectifier halves; when there is a height deviation between a steering wheel in the first rectifier halves and the corresponding steering wheel in the second rectifier halves, the height of a steering wheel and / or the corresponding steering wheel is adjusted.

[0054] Obtain the height of all steering wheels in the first and second rectifier halves. When the first and second rectifier halves are misaligned, meaning there is a height difference between a steering wheel in the first rectifier halves and its corresponding position in the second rectifier halves, the following steps can be taken: For example, if there is a height difference between the first steering wheel in the first rectifier halves and the first steering wheel in the second rectifier halves, the individual lifting mode of the first rectifier halves can be activated to raise or lower the first steering wheel, eliminating the height difference between the two steering wheels. Alternatively, the individual lifting mode of the second rectifier halves can be activated to raise or lower the first steering wheel, eliminating the height difference between the two steering wheels. Or, the individual lifting modes of the first and second rectifier halves can be activated to raise or lower the first steering wheels, eliminating the height difference between the two steering wheels.

[0055] This embodiment of the application achieves precise alignment of the teeth and the tooth holes by accurately measuring the deviation angle between the teeth and the holes, and controlling the rotation of the fairing half around the center clockwise or counterclockwise according to this deviation angle. Simultaneously, by determining the height of all the steering wheels of the first and second fairing halves, and adjusting the height of the steering wheels when height deviations exist, accurate alignment of the two fairing halves is ensured. These measures significantly improve the accuracy and reliability of fairing assembly, and reduce assembly errors and potential risks caused by inaccurate alignment.

The adjustment module 220 is configured to: adjust the target distance of one rudder wheel in the first and / or second fairing to the preset distance when the target distance is not reached, so that the center of the first and / or second fairing coincides with the center of the satellite's bottom circle; and control the first and / or second fairing to rotate in place when the teeth on the first and / or second fairing are not aligned with the teeth holes on the satellite, so that the teeth on the first and / or second fairing are aligned with the teeth holes on the satellite. Alignment of the toothed holes on the satellite; when the first and second rectifier halves are not aligned, adjust the height of the rudder wheels in the first and / or second rectifier halves to align the first and second rectifier halves; the shroud module 230 is configured to shroud the first and second rectifier halves together when the first and second rectifier halves meet preset conditions; the preset conditions include the center of the first and second rectifier halves coinciding with the center of the bottom of the satellite, the toothed holes on the first and second rectifier halves being aligned with the toothed holes on the satellite, and the alignment of the first and second rectifier halves.
