Aircraft development is a huge systematic engineering, Part dataset of traditional aircraft product structure including mass documents such as 2D drawings, 3D models, temporary change sheets and which change frequently, in the same time, it also costs manufacture and maintenance department a lot of work to reconstruct engineering data which easily to be mistaken, so the management of the product data is so complex, hard, and lower efficiency. Refer to the experiences of other international leading aircraft company, this paper develops a simplified product structure management solution based on module theory and three dimension design method. This paper takes an certain type aircraft for example, emphatically analyses the organized mode of product structure, the composition of engineering dataset, the rules for data change, to make sure the configuration data to be convenient and exactly, and this product structure management solution also conforms to the full digital trend of aircraft product development in the future.
