Problems solved by technology
Traditional aircraft development generally adopts a serial development model, and each development stage is carried out in chronological order. After a stage of development is completed, the data is released to the downstream. There is a lack of effective communication between various departments within the design unit. Due to the influence of systems and regions , the communication is more difficult
In order to complete the work, various departments usually extend the development plan time, resulting in a long aircraft development cycle. If the development process is changed, the change procedure is complicated and lengthy, which will lead to the delay of the plan

[0008] 1) Classification of Product Data Maturity
[0009] The maturity level of product data is based on the completeness of product data information, according to the requirements of design and manufacturing work, and based on the division of the integrated development process and milestones of civil aircraft. The data in the aircraft development process is divided into seven maturity levels: M1~7 grade. The main work contents of structural design under different maturity levels are shown in Table 1.
[0010] Within the design unit, relevant personnel such as structure, system, strength, and aerodynamics must carry out work in advance according to the maturity status of product design. For example, in the M2 maturity state of the overall digital model, which means that the aircraft shape surface is frozen, the overall layout model with information such as the frame position, frame axis, and stringer position is basically determined, and the intersection point diagram and th...

The invention discloses a maturity-based concurrent digital definition method of a large amphibious aircraft and relates to the field of aircraft digital concurrent engineering. Sequential development modes are usually used in traditional aircraft development, every development stage is started chronologically, however, lack of effective communication exists among insides of design departments and design and manufacture departments, many design errors exist, the efficiency is low and the period length is long. According to the maturity-based concurrent digital definition method of the large amphibious aircraft, milestones in an aircraft research and development process are taken as basis to define work contents of product data maturity levels and maturity of different levels, pre-issue is performed on product data, accordingly, works can be done concurrently among the insides of the design departments, design departments and manufacturing department, many problems can be solved in an early stage of development, products have good manufacturability, assembling ability and maintainability in a design stage, meanwhile, development time is greatly shortened and the design quality is guaranteed. The maturity-based concurrent digital definition method of the large amphibious aircraft is mainly applicable to concurrent working of design and manufacture during aircraft development processes.
Description
technical field [0001] The invention patent relates to the field of aircraft digital concurrent engineering. Background technique [0002] The invention patent is mainly used for the parallel digital definition project of large amphibious aircraft. Traditional aircraft development generally adopts a serial development model, and each development stage is carried out in chronological order. After a stage of development is completed, the data is released to the downstream. There is a lack of effective communication between various departments within the design unit. Due to the influence of systems and regions , the communication is even more difficult. In order to complete the work, various departments usually extend the development planning time, resulting in a long aircraft development cycle. If the development process is changed, the change procedure is complicated and lengthy, which will lead to the delay of the plan. The invention patent closely combines the development...
