Description

Technical Field

[0001] This invention relates to the field of seaplanes, and more particularly to a method for installing a wave-damping plate on a seaplane. Background Technology

[0002] A seaplane is an aircraft capable of taking off, landing, and parking on water. Upon landing, the high-speed seaplane impacts the water, creating a large wave at the nose. This wave splashes upwards along the sides of the nose, potentially damaging components such as the wings and engine. Therefore, wave-damping panels are installed on both sides of the seaplane's nose. These panels form downward-opening channels between themselves and the nose wall, blocking the upward-splashing waves and preventing them from continuing to propel the aircraft upwards. The wave-damping panels, installed on the underside of the seaplane's nose, are crucial for mitigating the impact of water waves and serve as a vital line of defense against waves. Their structure is characterized by its long length, narrow width, and thin thickness, making them a typical long-dimensional, thin-walled structural component. Furthermore, to meet the complex hydrodynamic requirements of the seaplane's nose, the wave-damping panels themselves have complex, irregularly shaped curved surfaces, resulting in a highly complex structural design.

[0003] Taking the wave-damping plate on the left side of an aircraft nose as an example, it is mainly divided into a front left wave-damping plate, a center left wave-damping plate, and a rear left wave-damping plate. These three plates are sequentially installed from the front of the aircraft nose towards the tail, forming a complete left-side wave-damping plate. The existing method of connecting the wave-damping plate to the aircraft nose involves connecting it to the top support and the side support at the crossbeam of the wave-damping plate. Since the wave-damping plate is a plate-like structure, the existing method requires all the top supports along the length of the wave-damping plate to be tooled and positioned on the aircraft nose, and then the joints on the wave-damping plate are aligned and connected to the top supports one by one. This results in a large number of top supports and connection points. Because there are many connection points between the wave suppressor and the top support, even when tooling is used for positioning when installing the top support onto the aircraft nose, the cumulative tolerances and deformation of the wave suppressor can lead to the inability to align the joints on the wave suppressor with the top support during the actual installation process. This poses a risk of misalignment or misplacing between the wave suppressor joints and the fuselage support, resulting in high installation difficulty and low installation efficiency, which seriously affects the installation efficiency of the wave suppressor. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a method for installing wave-suppressing plates on seaplanes that improves the installation efficiency of wave-suppressing plates.

[0005] The technical solution adopted by this invention to solve its technical problem is: a method for installing wave-damping panels on seaplanes, comprising the following steps:

[0006] a. Top supports are installed on both sides of the aircraft nose. The top supports are positioned by tooling. The number of top supports is sufficient to position the corresponding wave-damping plates.

[0007] b. Install the left front wave-suppressing plate and the left middle wave-suppressing plate sequentially on the left side of the aircraft nose; the left front wave-suppressing plate and the left middle wave-suppressing plate are respectively connected to the aircraft nose through at least one top support positioned by a tooling; install the right front wave-suppressing plate and the right middle wave-suppressing plate sequentially on the right side of the aircraft nose; the right front wave-suppressing plate and the right middle wave-suppressing plate are respectively connected to the aircraft nose through at least one top support positioned by a tooling; a first gap is reserved between the left front wave-suppressing plate and the left middle wave-suppressing plate, and a second gap is reserved between the right front wave-suppressing plate and the right middle wave-suppressing plate.

[0008] c. Set the left front middle wave-suppressing plate in the first gap and the right front middle wave-suppressing plate in the second gap; after the installation positions of the left front middle wave-suppressing plate and the right front middle wave-suppressing plate are adjusted, connect them to the aircraft nose through the connectors. After connecting them to the aircraft nose, remove the process allowance of the left front middle wave-suppressing plate and the right front middle wave-suppressing plate.

[0009] d. Install the remaining top support at the aircraft nose section corresponding to the joint of the wave-suppressing plate crossbeam. Connect the joint of the wave-suppressing plate crossbeam to the top support of the aircraft nose section, and connect the wave-suppressing plate crossbeam to the side support of the aircraft nose section to complete the installation of the wave-suppressing plate.

[0010] Furthermore, the wave suppressor includes a left rear wave suppressor and a right rear wave suppressor; in step b, the left front wave suppressor, left center wave suppressor, and left rear wave suppressor are sequentially installed on the left side of the aircraft nose, with the left rear wave suppressor connected to the aircraft nose via at least one top support positioned by a tooling fixture; the right front wave suppressor, right center wave suppressor, and right rear wave suppressor are sequentially installed on the right side of the aircraft nose; the right rear wave suppressor is connected to the aircraft nose via at least one top support positioned by a tooling fixture. A third gap is reserved between the left center wave suppressor and the left rear wave suppressor, and a fourth gap is reserved between the right center wave suppressor and the right rear wave suppressor. In step c, the left center and rear wave suppressors are placed in the third gap, and the right center and rear wave suppressors are placed in the fourth gap. After the installation positions of the left center and rear wave suppressors and the right center and rear wave suppressors are adjusted, they are connected to the aircraft nose through connectors. After connecting to the aircraft nose, the process allowance of the left center and rear wave suppressors and the right center and rear wave suppressors is removed.

[0011] Furthermore, in step d, the wave-damping plate is connected to the side support of the aircraft nose sidewall via a wave-damping plate tie rod.

[0012] Furthermore, in step b, the left front center wave suppressor and the right front center wave suppressor are provided with initial holes before installation. After the installation position is adjusted, the initial holes are drilled to obtain the final holes and the connectors are installed.

[0013] Furthermore, in step b, after the left, middle and rear wave suppressor plates and the right, middle and rear wave suppressor plates have been adjusted in their installation positions, holes are drilled and connecting parts are installed.

[0014] The beneficial effects of this invention are:

[0015] 1. In actual installation, the top supports are first installed on the aircraft nose. At this point, only a portion of the top supports need to be installed using tooling positioning; that is, only a small number of top supports are needed to position the corresponding wave suppressor plate. It is not necessary to install all the top supports on the aircraft nose, thus greatly reducing the number of top supports required for tooling positioning. The remaining top supports simply need to be directly connected to the wave suppressor plate at the connection points in the final step, therefore there is no longer any cumulative tolerance in the extension direction of the wave suppressor plate.

[0016] Second, taking the left-side wave-suppressing plate as an example, the addition of the left front-middle wave-suppressing plate and the left middle-rear wave-suppressing plate shortens the length of the left front wave-suppressing plate and the left middle wave-suppressing plate. This reduces the cumulative tolerance of the top support of the aforementioned tooling positioning in the extension direction of the wave-suppressing plate and reduces the impact of wave-suppressing plate deformation on installation. It effectively ensures that the joints on the wave-suppressing plate and a small number of top supports can be aligned one by one to achieve positioning, reducing the risk of misalignment or misplacing of the wave-suppressing plate joints and the machine body support, making the installation of the wave-suppressing plate simpler and improving installation efficiency.

[0017] Third, taking the left-side wave suppression plate as an example, when installing the left front-middle wave suppression plate and the left middle-rear wave suppression plate in the later stage, the corresponding installation error compensation can be achieved simply by removing the reserved process allowance, which reduces the installation difficulty while ensuring installation accuracy.

[0018] This invention is particularly applicable to the wave-damping plate installation process of large seaplanes. Attached Figure Description

[0027] The components in the diagram are marked as follows: aircraft nose 1, top support 11, side support 12, wave suppressor tie rod 121, wave suppressor 2, wave suppressor crossbeam 201, left front wave suppressor 21, left front middle wave suppressor 211, right front wave suppressor 22, right front middle wave suppressor 221, left middle wave suppressor 23, right middle wave suppressor 24, left rear wave suppressor 25, left middle rear wave suppressor 251, right rear wave suppressor 26, right middle rear wave suppressor 261, and process allowance portion 27. Detailed Implementation

[0028] The invention will be further described below with reference to the accompanying drawings.

[0029] like Figures 6 to 7 The diagram shows the existing method for installing wave depressors, with wave depressors 2 installed on both the left and right sides of the aircraft nose 1. The original wave depressors 2 are divided into three sections: the left wave depressor 2 consists of a left front wave depressor 21, a left middle wave depressor 23, and a left rear wave depressor 25; the right wave depressor 2 consists of a right front wave depressor 22, a right middle wave depressor 24, and a right rear wave depressor 26. Taking the left wave depressor 2 as an example, the existing method uses the left front wave depressor 21, the left middle wave depressor 23, and the left rear wave depressor 25 to form a complete left wave depressor 2. The wave depressor 2 is connected to the top support 11 of the aircraft nose 1 via a connecting rod at the top of its wave depressor beam 201, and to the side support 12 of the aircraft nose 1 via a wave depressor tie rod 121 on the side of its wave depressor beam 201. The side support 12 is fixed to the side wall of the aircraft nose 1, and the groove-shaped area between the side wall and the wave-damping plate 2 is the wave-damping groove. Among them, with... Figure 8As shown, in the existing scheme, several top supports 11 are evenly arranged on the nose 1 of the aircraft along the extension direction of the wave suppressor 2. Since there are numerous top supports 11, and the installation and positioning of each top support 11 requires tooling, the increasing number of installed top supports 11 leads to positioning errors caused by accumulated tolerances. Furthermore, the influence of factors such as deformation of the wave suppressor 2 further exacerbates this, easily causing the joints on the top connecting rod of the wave suppressor 2 to not align with the mounting holes of the top supports during actual installation. This poses a risk of misalignment or misfitting between the joints of the wave suppressor 2 and the fuselage supports, making the installation of the wave suppressor difficult.

[0030] like Figures 1 to 5 The illustration shows an embodiment of the seaplane wave-damping plate installation method of this scheme. Figure 1 The illustration shows an embodiment of the wave-suppressing plate 2 in this scheme. Specifically, the wave-suppressing plate 2 is divided into 5 segments. The left wave-suppressing plate 2 includes, in sequence, a left front wave-suppressing plate 21, a left front middle wave-suppressing plate 211, a left middle wave-suppressing plate 23, a left middle rear wave-suppressing plate 251, and a left rear wave-suppressing plate 25. The right wave-suppressing plate 2 includes, in sequence, a right front wave-suppressing plate 22, a right front middle wave-suppressing plate 221, a right middle wave-suppressing plate 24, a right middle rear wave-suppressing plate 261, and a right rear wave-suppressing plate 26. Taking the left wave-suppressing plate 2 as an example, the addition of the left front middle wave-suppressing plate 211 and the left middle rear wave-suppressing plate 251 can shorten the length of the left front wave-suppressing plate 21, the left middle wave-suppressing plate 23, and the left rear wave-suppressing plate 25, thereby reducing the cumulative tolerance during the positioning process of the top support 11. Figure 2 The example shown is the right front center wave suppressor 221 and the right center rear wave suppressor 261. The process allowance 27 is set and can be removed by cutting after the right front center wave suppressor 221 and the right center rear wave suppressor 261 are connected to the aircraft nose 1.

[0031] Figures 3 to 5 The diagram shows the installation steps for the wave suppressor on the left side of the aircraft nose 1 in this design, while the installation steps for the right side of the aircraft nose 1 are the same as those for the left side. First, as... Figure 3 As shown, a small number of top supports 11 and all the side supports 12 are installed on the nose 1 of the aircraft. The specific installation positions of the top supports 11 are determined by tooling, and the number of top supports 11 is sufficient to position the corresponding wave-damping plates 2. Figure 3 As shown, the number of top supports 11 is compared to Figure 8The number of top supports 11 shown has been greatly reduced. Meanwhile, since the installation accuracy requirements of the side supports 12 are lower than those of the top supports 11, when installing the side supports 12 on both sides of the aircraft nose 1, only a portion of the side supports 12 are selected for tooling positioning, while the majority of the aircraft nose 1 sides are positioned and installed using a hole system. As can be seen from the above steps, this solution significantly reduces the number of tooling positioners and increases the internal operating space of the tooling.

[0032] Subsequently, as Figure 4 As shown, the installation of the left front wave suppressor 21, left center wave suppressor 23, and left rear wave suppressor 25 is completed first. Specifically, during installation, the connecting rod at the top of the wave suppressor crossbeam 201 on the left front wave suppressor 21, left center wave suppressor 23, and left rear wave suppressor 25 is connected to the top support 11 of the aircraft nose 1. Since the top supports 11 that have already been installed are all positioned using tooling, accurate positioning of the left front wave suppressor 21, left center wave suppressor 23, and left rear wave suppressor 25 can also be achieved. The remaining top supports 11 will be installed in subsequent steps. The right front wave suppressor 22, right center wave suppressor 24, and right rear wave suppressor 26 on the right side of the aircraft nose 1 are also installed following the same steps on the right side of the aircraft nose 1. Among them, a first gap is reserved between the left front wave suppressor 21 and the left middle wave suppressor 23, a second gap is reserved between the right front wave suppressor 22 and the right middle wave suppressor 24, a third gap is reserved between the left middle wave suppressor 23 and the left rear wave suppressor 25, and a fourth gap is reserved between the right middle wave suppressor 24 and the right rear wave suppressor 26.

[0033] Next, as Figure 5As shown, the left front center wave suppressor 211 is positioned in the first gap reserved between the left front wave suppressor 21 and the left center wave suppressor 23, and the left center rear wave suppressor 251 is positioned in the third gap between the left center wave suppressor 23 and the left rear wave suppressor 25. Correspondingly, the right front center wave suppressor 221 is positioned in the second gap reserved between the right front wave suppressor 22 and the right center wave suppressor 24, and the right center rear wave suppressor 261 is positioned in the fourth gap. The left front center wave suppressor 211 and the right front center wave suppressor 221 have initial holes prepared before installation. After the installation position is adjusted, the initial holes are drilled to obtain the final holes, and the connecting parts are installed. The connecting parts can be existing connecting rods. The left center rear wave suppressor 251 and the right center rear wave suppressor 261 have their holes drilled directly after the installation position is adjusted, and the connecting parts are installed. After the left front center wave suppressor 211, right front center wave suppressor 221, left center rear wave suppressor 251, and right center rear wave suppressor 261 are connected to the side supports 12 of the aircraft nose 1 via connecting rods, the process allowance 27 of each of the following wave suppressors 211, right front center wave suppressor 221, left center rear wave suppressor 251, and right center rear wave suppressor 261 is removed according to actual needs. Then, the remaining top supports 11 are installed at the aircraft nose 1 corresponding to the joint of the wave suppressor beam 201 of the wave suppressor 2. The joint at the top of the wave suppressor beam 201 of the wave suppressor 2 is connected to the remaining top supports 11 of the aircraft nose 1, and the wave suppressor beam 201 of the wave suppressor 2 is connected to the side supports 12 of the aircraft nose 1. Thus, the connection between the wave suppressor 2 and all the top supports 11 and all the side supports 12 is completed, and the installation of the wave suppressor 2 is finally finished.
