Problems solved by technology

[0004] In most companies in my country, the stowage is completed by the stowage personnel through the off-duty system. The loading plan is mainly based on personal experience, which has great personal subjectivity and limitations, and it is difficult to consider the overall situation
When encountering an emergency, it is difficult to propose an optimization plan in a short time
The levels of existing stowage technicians vary greatly, there is no unified technical standard and work process, and there is arbitrariness in technical supervisors

Embodiment 1

[0047] combine figure 1 , this embodiment proposes a trim loading method for passenger aircraft, which is used to optimize the loading scheme of passenger aircraft. The trim loading method is mainly based on the airline's load balance manual, loading manifest, etc., based on a certain For a specific aircraft type, the actual loading situation is converted into a mathematical model; the model is solved by an intelligent optimization algorithm, and a passenger and cargo loading scheme considering the optimal center of gravity cargo compartment is given. The specific implementation steps are as follows:

[0048] S1: Determine the number of passengers and the quantity of cargo, and obtain model data, which includes the original center of gravity envelope, passenger cabin layout, and cargo cabin layout.

[0049] S2: Preset standard center-of-gravity data within the range of the original center-of-gravity envelope.

[0050] S3: With the goal of minimizing the center of gravity devi...

Embodiment 2

[0106] The difference from Embodiment 1 is that in this embodiment, the original center of gravity envelope is cut to obtain the operating center of gravity envelope, and the preset standard center of gravity data in step S2 is obtained within the range of the operating center of gravity envelope.

[0107] In each flight phase, the area boundary line composed of the allowable center of gravity positions is called the center of gravity envelope of the aircraft. The original center-of-gravity envelope of each type of civil aircraft is composed of the aircraft's maximum weight, maximum take-off weight, maximum landing weight and maximum zero-fuel weight, as well as the corresponding center of gravity restrictions. In order to ensure flight safety, in any case, the position of the center of gravity of the aircraft cannot exceed the limit of the envelope of the center of gravity. However, during the operation of the aircraft, the movement of personnel and dining cars will cause the...

Embodiment 3

[0131] This embodiment proposes a trim loading device for a passenger aircraft, which adopts the above-mentioned trim loading method for a passenger aircraft, and the device includes an input terminal, a memory, a microprocessor, and a display connected to the microprocessor.

[0132] The input end is used for manual input or importing information to be allocated in the form of a file, the information to be allocated includes standard center of gravity data, passenger and cargo quantity information; the input end includes electronic equipment such as keyboards and U disks;

[0133] The memory is used to store key information, and the key information includes cabin layout, cargo cabin layout, and original center of gravity envelope;

[0134] The microprocessor is used to randomly assign the positions of passengers and cargo according to the input information at the input end, calculate the actual center of gravity data of the aircraft corresponding thereto, and perform an absolu...

Abstract

The present invention mainly relates to a trim loading method of a passenger aircraft, comprising the following steps: obtaining model data, the model data including the original center of gravity envelope, passenger cabin layout, and cargo hold layout; within the scope of the original center of gravity envelope, preset standards Center of gravity data; determine the number of passengers and the quantity of cargo, based on the cabin layout and cargo cabin layout, with the goal of minimizing the deviation of the center of gravity, establish an integer programming model for aircraft loading, pre-allocate the positions of passengers and cargo, and use heuristic intelligent algorithms, Iteratively optimize the model to determine the target loading scheme. Based on the trim loading method proposed by the present invention, positive effects such as loading visualization, one-key optimization, and analysis of center of gravity deviation of loading can be realized.

Description

technical field [0001] The invention relates to the field of aircraft loading, in particular to a trim loading method and device for passenger aircraft. Background technique [0002] Passenger load balance is to control the aircraft's payload weight by rationally allocating the positions of passengers, cargo, mail, luggage, etc. in the aircraft cabin and cargo compartment, and properly adjust the aircraft's center of gravity, so that the aircraft's center of gravity is within a reasonable range. [0003] Stowage is a multi-objective combinatorial optimization problem with complex constraints, which has important scientific significance and application value. Many scholars at home and abroad have conducted many useful explorations on related issues. However, due to the large scale and complexity of the air freight loading problem, and involving many fuzzy and random factors, so far, the trim loading method in the industry still relies on manual judgment, and the degree of aut...
