Description

Technical Field

[0001] This utility model relates to the field of aircraft test model technology, and in particular to an aircraft model cabin spine structure and fuselage bonding structure. Background Technology

[0002] The "cabin ridge" is a very prominent feature of the back of an aircraft fuselage. It is usually a raised structure that starts behind the cockpit and extends rearward along the back of the fuselage. It is not only part of the aircraft's shape, but also plays an important role.

[0003] The main functions of the ridge are to provide internal space, improve airflow, contribute to stability, and accommodate equipment. The internal space is used to lay out wiring and pipelines, streamline the airflow to make it smoother, reduce airflow separation, reduce flight drag, and increase the area of ​​the fuselage dorsal fin to provide additional directional stability.

[0004] Currently, during the wind-driven testing of the ridge, it is necessary to conduct detailed research on the airflow effect and measure data such as the distribution of pressure on the fuselage surface. Several sensors need to be installed in various parts of the ridge, which will disassemble the ridge into a multi-piece structure. Although the ridge is mostly a disposable item, its manufacturing precision requirements are very high. In terms of bonding, manual gluing can cause resonance, breakage during testing, and other issues that interfere with the test data. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adhesive structure for bonding the spine structure of an aircraft model to the fuselage, an adhesive structure that provides uniform testing results.

[0006] The purpose of this utility model is achieved through the following technical solution: an aircraft model cabin spine structure and fuselage bonding structure, wherein the cabin spine includes an upper spine strip, a lower spine strip and an adhesive plate for connecting the upper spine strip and the lower spine strip, the upper spine strip, the adhesive plate and the lower spine strip form a streamlined cabin spine structure, the top surface of the adhesive plate is provided with an adhesive layer for use with the upper spine strip, and the bottom surface of the adhesive plate is at least partially embedded in the lower spine strip for bonding.

[0007] The separation of the upper and lower ridge strips provides more installation positions, making installation more convenient and eliminating the need for drilling again. Furthermore, the use of adhesive plates allows for secondary connections to ensure modular and scalable universal use.

[0008] The present invention is further configured such that a strip-shaped adhesive groove is provided on the top surface of the lower ridge strip.

[0009] The strip-shaped adhesive groove can increase the bonding contact area, making it easier to apply adhesive and increasing the amount of adhesive applied.

[0010] The present invention is further configured such that: an adhesive block is provided on the bottom surface of the adhesive plate, the adhesive block is embedded in the adhesive groove, and an adhesive layer is provided between the adhesive plate and the top surface of the lower ridge strip.

[0012] The present invention is further configured such that: an inner groove is provided on the side of the lower ridge strip, and the inner groove extends at least partially from the side of the adhesive groove toward the bottom of the lower ridge strip.

[0013] The recessed groove allows for easy side inspection after the upper and lower ridge bars are installed, enabling a final check to ensure proper installation and successful calibration.

[0014] The present invention is further configured such that a side plate capable of completely filling the inner groove is provided inside the inner groove.

[0015] The inner recess is filled by the side panels to achieve the aerodynamic shape of the complete ridge.

[0016] The present invention is further configured such that the adhesive layer is distributed in a biomimetic pattern of Victoria amazonica.

[0038] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in further detail below, but the scope of protection of the present invention is not limited to the following description.

[0039] like Figure 1 As shown, an aircraft model cabin spine 1 structure is bonded to the fuselage. The cabin spine 1 includes an upper spine 2, a lower spine 4, and an adhesive plate 3 for connecting the upper spine 2 and the lower spine 4. The upper spine 2, the adhesive plate 3, and the lower spine 4 form a streamlined cabin spine 1 structure.

[0040] The top surface of the adhesive plate 3 is provided with an adhesive layer that works in conjunction with the upper ridge 2, and the bottom surface of the adhesive plate 3 is at least partially embedded in the lower ridge 4 for bonding.

[0041] The separation of the upper ridge strip 2 and the lower ridge strip 4 provides more installation positions, making installation more convenient and eliminating the need for drilling again. The secondary connection through the adhesive plate 3 ensures modular and large-scale universal use, while prefabrication ensures test stability.

[0042] The top surface of the lower ridge strip 4 is provided with a strip-shaped adhesive groove 41; the strip-shaped adhesive groove 41 can increase the adhesive contact surface, making it easier to apply adhesive and increasing the amount of adhesive applied.

[0043] An adhesive block 31 is provided on the bottom surface of the adhesive plate 3. The adhesive block 31 is embedded in the adhesive groove 41. An adhesive layer is provided between the top surface of the adhesive plate 3 and the lower ridge strip 4. The preparation effect is achieved by filling the gap between the adhesive plate 3 and the adhesive groove 41 with the adhesive layer.

[0044] The lower ridge 4 has an inner groove 42 on its side, which extends at least partially from the side of the adhesive groove 41 to the bottom of the lower ridge 4. The inner groove 42 allows for easy observation from the side after the upper ridge 2 and lower ridge 4 are installed to check whether the installation is neat and whether the calibration is successful.

[0045] The inner groove 42 is provided with a side plate 5 that can completely fill the inner groove 42; the inner groove 42 is filled by the side plate 5 to achieve the complete aerodynamic shape of the ridge 1.

[0046] In this embodiment, all adhesive layers are distributed in a biomimetic Victoria amazonica pattern with the adhesive. By pre-forming the adhesive into a biomimetic Victoria amazonica pattern, the coverage can be effectively improved, the weight can be reduced, and the uniformity of the connection can be improved, thus avoiding resonance.

[0047] In this embodiment, all adhesive layers are prefabricated using cloth-based adhesive. By distributing different biomimetic Victoria amazonica-shaped cloth-based adhesive sheets that are adapted to the shape of the adhesive surface, the prefabricated cloth-based adhesive can distribute the adhesive more evenly, achieving uniformity and less adhesive usage, thereby reducing weight and avoiding resonance.

[0048] In this embodiment, the biomimetic distribution of the adhesive can also provide more mounting space and prevent sensors, wires and other devices from getting too much adhesive on them.

[0049] Working principle: First, after all the sensors and wiring are set up, a pre-made fabric adhesive sheet is placed on the lower ridge 4. Then, the adhesive block 31 is embedded in the adhesive groove 41. The pre-made fabric adhesive sheet is attached to the upper ridge 2 and connected to the top surface of the adhesive plate 3. Finally, the side plate 5 is embedded in the inner groove 42. Because of the adhesive block 31, the inner groove 42 is pre-set with adhesive to complete the fixation of the ridge 1.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
