[0038] like Figures 1 to 3 As shown, this utility model provides a calibration airborne equipment bracket for helicopters. The calibration airborne equipment bracket is mounted on the upper skid of the helicopter and includes:

[0039] The left connecting component is connected to the upper left skid 3 of the helicopter;

[0040] The right connecting component is connected to the upper right skid 4 of the helicopter;

[0041] Support beam 12, the left end of support beam 12 is connected to the left connecting component, and the right end of support beam 12 is connected to the right connecting component;

[0042] When installing the calibration airborne equipment 14, the calibration airborne equipment 14 is set on the support beam 12.

[0043] Specifically, the helicopter has two skids on the left side of its bottom: the upper left skid 3 and the lower left skid. Similarly, the helicopter has two skids on the right side of its bottom: the upper right skid 4 and the lower right skid. The upper skids consist of the symmetrical upper left skid 3 and upper right skid 4, while the lower upper skids consist of the symmetrical lower left skid and lower right skid.

[0044] The calibration airborne equipment 14 is fixedly installed on the support beam 12. The left end of the support beam 12 is connected to the upper left skid 3 of the helicopter via the left connecting component, and the right end of the support beam 12 is connected to the upper right skid 4 of the helicopter via the right connecting component.

[0045] This invention provides a calibration airborne equipment bracket for helicopters. The bracket is fixedly mounted on an upper skid outside the helicopter cockpit, and the calibration airborne equipment 14 is fixedly mounted on the bracket. This reduces vibration of the calibration airborne equipment 14, effectively improving the accuracy and efficiency of helicopter dynamic calibration. It also allows the calibration airborne equipment 14 to be mounted outside the helicopter cockpit, saving cockpit space and minimizing the impact of airflow deformation during flight. This shortens the data processing cycle and solves the problem of rapid calibration.

[0046] Furthermore, the middle of the support beam 12 is recessed, and the calibration airborne equipment 14 is located at the recessed middle of the support beam 12.

[0047] The recessed middle section of the support beam 12 can avoid the nose shell of the helicopter, providing installation height space for the calibration of the airborne equipment 14.

[0048] The calibration airborne equipment 14 is located in the recessed part of the middle of the support beam 12. This allows for a compact structure, reduces wind resistance, and minimizes the impact of airflow deformation during flight. It also reduces vibration of the calibration airborne equipment 14 mounted on the support beam 12.

[0049] Furthermore, the calibration airborne equipment bracket also includes an equipment mounting base 13, which is located in the recessed part of the middle of the support beam 12, and has multiple mounting positions.

[0050] The equipment mounting base 13 can be connected to the support beam 12 by means of clamps, bolts, or welding.

[0051] The equipment mounting base 13 has multiple mounting positions, which facilitate the installation of the calibration airborne equipment 14.

[0052] Furthermore, the calibration airborne equipment 14 includes multiple monitoring devices, each of which is installed in a corresponding mounting position.

[0053] Each monitoring device is installed in a designated mounting location. This not only facilitates the installation of the monitoring equipment but also makes subsequent maintenance and replacement easier.

[0054] like Figures 1 to 3 As shown, in some optional embodiments, the present invention provides a calibration airborne equipment bracket for helicopters, the calibration airborne equipment bracket further comprising:

[0055] The left connecting seat assembly supports the left end of the crossbeam 12 and is connected to the left connecting assembly.

[0056] The right connecting seat assembly supports the right end of the crossbeam 12 and connects it to the right connecting assembly.

[0057] Furthermore, the left connecting seat assembly includes a left vertical connecting plate 7 and a left horizontal connecting plate 9. The left horizontal connecting plate 9 is connected to the left connecting assembly through the left vertical connecting plate 7, and the left end of the supporting beam 12 is connected to the left horizontal connecting plate 9 through a snap-fit ​​11.

[0058] The right connecting seat assembly includes a right vertical connecting plate 8 and a right horizontal connecting plate 10. The right horizontal connecting plate 10 is connected to the right connecting assembly through the right vertical connecting plate 8, and the right end of the supporting beam 12 is connected to the right horizontal connecting plate 10 through a snap-fit ​​member 11.

[0059] In detail, the left end of the supporting beam 12 is connected to the left connecting assembly via the left connecting seat assembly, and the right end of the supporting beam 12 is connected to the right connecting assembly via the right connecting seat assembly.

[0060] The left and right connecting bracket assemblies can raise the height of the support beam 12. This prevents the calibration onboard equipment 14 on the support beam 12 from contacting the ground and being damaged due to the helicopter's tilt during landing.

[0061] The left horizontal connecting plate 9 is bolted to the left connecting component via the left vertical connecting plate 7, which facilitates disassembly, installation and maintenance.

[0062] The right horizontal connecting plate 10 is bolted to the right connecting component via the right vertical connecting plate 8, which facilitates disassembly, installation and maintenance.

[0063] The left end of the supporting beam 12 is connected to the left horizontal connecting plate 9 via a snap-fit ​​connector 11, which facilitates disassembly, installation and maintenance.

[0064] The right end of the supporting beam 12 is connected to the right horizontal connecting plate 10 via a snap-fit ​​connector 11, which facilitates disassembly, installation and maintenance.

[0065] Furthermore, this utility model provides a calibration airborne equipment bracket for helicopters, which further includes a camera device 15, which can be selectively mounted on the right horizontal connecting plate 10 or the left horizontal connecting plate 9.

[0066] The camera device 15 is mounted on either the right horizontal connecting plate 10 or the left horizontal connecting plate 9. Mounting the camera device 15 outside the cab saves interior space.

[0067] like Figures 1 to 3As shown, in some optional embodiments, the present invention provides a calibration airborne equipment bracket for helicopters. The left connecting component of the calibration airborne equipment bracket includes an upper left connector 5 disposed above the outer surface of the upper left skid 3 and a lower left connector 1 disposed below the outer surface of the upper left skid 3. The upper left connector 5 and the lower left connector 1 are connected by bolts to clamp the upper left skid 3.

[0068] The right connection assembly of the calibration airborne equipment bracket includes an upper right connector 6 located above the outer surface of the upper right slide 4 and a lower right connector 2 located below the outer surface of the upper right slide 4. The upper right connector 6 and the lower right connector 2 are connected by bolts to clamp the upper right slide 4.

[0069] Using the above structure to install a calibration airborne equipment bracket on a helicopter eliminates the need for additional drilling for external load fixation. It is lightweight, easy to install quickly, requires no additional counterweight, and keeps the helicopter within flight safety limits. The aerodynamic impact during flight is minimal, and the equipment will not experience significant vibration.

[0070] Furthermore, a groove is provided below the upper left connector 5 to mate with the outer surface of the upper left slide 3, and a groove is provided above the lower left connector 1 to mate with the outer surface of the upper left slide 3.

[0071] The lower part of the upper right connector 6 is provided with a groove that mates with the outer surface of the upper right sliding skid 4, and the upper part of the lower right connector 2 is provided with a groove that mates with the outer surface of the upper right sliding skid 4.

[0072] With the above structure, the left connecting component can be more stably fixedly connected to the upper left sliding skid 3. The right connecting component can be more stably fixedly connected to the upper right sliding skid 4.

[0073] In summary, this utility model provides a calibration airborne equipment bracket for helicopters. This bracket is fixedly installed on an upper skid outside the helicopter cockpit, and the calibration airborne equipment 14 is fixedly installed on the bracket. This reduces the vibration of the calibration airborne equipment 14, effectively improving the accuracy and efficiency of helicopter dynamic calibration. Furthermore, the calibration airborne equipment 14 can be installed outside the helicopter cockpit, saving cockpit space and being less affected by airflow deformation during flight. It also shortens the data processing cycle and solves the problem of rapid calibration.

[0074] Adding a standard airborne equipment bracket to a helicopter eliminates the need for additional drilling for external load fixation. The bracket is lightweight, easy to install quickly, and requires no additional counterweight. The helicopter remains within flight safety limits, with minimal aerodynamic impact during flight and minimal equipment vibration.
