Description

Technical Field

[0001] The invention relates to a method for installing a cabin partition of an aircraft, and in particular to a method for installing a cabin partition on an aircraft by means of a luggage box pull rod overhead. Background Art

[0002] In the pursuit of modern aircraft design, creating a comfortable flying environment for passengers, especially through ingenious cabin space layout, has become one of the core considerations of design.

[0003] Among them, the compartment partition, as a key component inside the cabin, not only plays multiple roles such as dividing space, enhancing privacy, and reducing noise, but also becomes a unique aesthetic element.

[0004] Compared with the half-height design of the past, today's full-height compartment partitions have more advantages in improving the passenger experience. However, the problem of its top connection has also emerged accordingly, becoming a technical challenge. In the current market, the top connection design of the full-height compartment partition is generally directly related to the aircraft's bulkhead structure, and this connection method deeply involves the mechanical analysis of the aircraft structure. In order to achieve this connection, it is often necessary to conduct in-depth cooperation with aircraft manufacturers such as Boeing, Airbus and other OEMs, relying on the detailed drawings and professional force analysis program reports they provide. Only in this way can it be possible to accurately drill holes in key parts of the aircraft structure, such as the bulkhead, to install full-height partitions that bear a certain weight. In this process, the proprietary data and technical requirements provided by the OEM form a major technical barrier to the top installation of full-height partitions.

[0005] In order to ensure that passengers can enjoy a smoother and more comfortable experience during the flight, the installation method of the compartment partition is particularly critical. It must not only be easy to install and remain stable, but also ensure the comfort of passengers during use.

[0006] The traditional installation method of the upper part of the aircraft compartment partition is: first, properly install a filler panel on the luggage compartment; then, accurately insert the two pins on the upper part of the partition into the reserved holes in the center of the filler panel. It is worth noting that this connection method belongs to the category of flexible connection. Its original design is not used to bear heavy weight loads, but is tailored for light and compact half-height compartment partitions. However, the traditional installation method of the upper part of the compartment partition has many limitations, such as complex operation, high resource consumption, and fixed installation position, which to a certain extent limit its use effect. Summary of the invention

[0007] The purpose of the present invention is to provide a method for installing a compartment partition on an aircraft by means of an overhead luggage box pull rod. The method utilizes the existing structure of the aircraft overhead luggage box bracket as a support to achieve the installation of the compartment partition without adding additional auxiliary installation brackets or structures, thereby avoiding the tediousness and burden of adding additional auxiliary installation components, significantly reducing the occupation of the aircraft's internal space, reducing the weight of the fuselage, and reducing the overall cost.

[0008] The above-mentioned object of the present invention is achieved by the following technical solution: a method for installing a compartment partition on an aircraft through an overhead luggage box pull rod, characterized in that the method comprises the following steps:

[0009] Step 1: Install the bottom of the compartment partition on the slide rail in the aircraft cabin, install a U-shaped bracket on the upper part of the compartment partition, and fix the U-shaped bracket on the compartment partition by fasteners to ensure the stability of the installation of the U-shaped bracket;

[0010] Step 2: Connect the luggage box bracket to the U-shaped bracket through fasteners;

[0011] Step 3: Connect one end of the luggage case pull rod to the luggage case bracket and the other end to the aircraft bulkhead to ensure that the luggage case pull rod is firmly installed; the luggage case bracket is used as a support to achieve the installation and positioning of the compartment partition without adding additional auxiliary mounting brackets or structures;

[0012] Step 4: After the compartment bulkheads are installed, conduct a comprehensive inspection to ensure that all fasteners are connected and fixed, and that the installation position of the compartment bulkheads is appropriate and secure.

[0013] Compared with the existing installation technology of compartment partitions, the present application proposes a revolutionary method for installing compartment partitions. This method cleverly uses the luggage compartment bracket on the top of the aircraft, an existing component inside the aircraft, as a support point. The installation of the compartment partition can be completed without adding additional auxiliary installation brackets or structures. This not only simplifies the installation process and reduces the investment in manpower and material resources, but also ensures the stability of the installation of the compartment partition.

[0014] Moreover, the compartment partition installed by this method can be installed only through the ground anchors and the aircraft seat slide rails and the luggage compartment pull rod, and no longer needs to be connected to other components in the aircraft cabin, so that the installation of the compartment partition is completed.

[0015] In the present invention, the compartment partition is a full-height compartment partition or a half-height compartment partition.

[0016] In the present invention, the position where the U-shaped bracket is installed on the compartment partition corresponds to the position of the luggage case pull rod, ensuring that the luggage case pull rod remains substantially horizontal after installation.

[0017] In the present invention, the luggage case bracket is a flat bracket, and the plane of the luggage case bracket is completely in contact with the plane of the U-shaped bracket.

[0018] The present invention can be improved as follows: the luggage case pull rod is a telescopic pull rod with adjustable length, which can be used to adjust the installation position of the compartment partition, so that the space layout in the aircraft cabin can be flexibly adjusted according to the actual needs of the passengers, thereby further improving the passengers' flight experience.

[0019] The present invention can be further improved as follows: the luggage box bracket and the U-shaped bracket are provided with connecting holes, and the installation position of the compartment partition is fine-tuned by setting different opening positions, and the installation position of the compartment partition is adjusted together with the luggage box pull rod. The secondary adjustment can meet the needs of the compartment partition to adapt to the internal space of different models, and can also eliminate assembly problems caused by component processing errors.

[0020] The present invention provides higher flexibility for the installation of compartment partitions. Through the retractable luggage case pull rod and the fine-tuning structure between the luggage case bracket and the U-shaped bracket, the spatial layout of the cabin can be flexibly adjusted, so that the spatial layout inside the aircraft can be flexibly adjusted according to the actual needs of the passengers, thereby further improving the passengers' flight experience.

[0021] In the present invention, the fasteners are all fastening screws.

[0022] Compared with the prior art, the method of installing the compartment partition on the aircraft through the overhead luggage box pull rod of the present invention has the advantages of simple installation, low cost, stability and reliability. The installation and positioning of the compartment partition can be achieved by using the existing structure of the overhead luggage box bracket as a support point, avoiding the tediousness and burden of adding additional brackets or structures, significantly reducing the space occupied inside the aircraft, reducing the weight of the fuselage, and reducing the overall cost.

[0023] As a further extension of the present application, the load-bearing capacity of the luggage suitcase pull rod and bracket can be calculated according to the load specified in the suitcase. Specifically, the weight of the suitcase and the range of the weight that can be supported can be obtained by consulting the aircraft WBM (load and balance manual) and the maximum load-bearing plate on the suitcase, so as to calculate the maximum force of 9G that the luggage suitcase pull rod can withstand forward in an emergency. By calculating the maximum load that the suitcase pull rod can withstand in the forward direction, it can be verified whether the full-height partition complies with the relevant airworthiness regulations, thereby ensuring that the partition design meets the various requirements specified in the airworthiness regulations without relying on the data provided by the aircraft manufacturer. The calculation is mainly based on Article 561 of CCAR25, which is one of the bases for whether the compartment partition can be installed on the aircraft. The calculation results are used to ensure that the load-bearing performance of the compartment partition is within the range required by industry specifications. BRIEF DESCRIPTION OF THE DRAWINGS
