Research on the New Airplane Develop System Based on 3D-digital Technique and Multi-companies Collaboration

The paper mainly covers the Goal, the Plan and the Content of the New Airplane Develop System Based on 3D-Digital Technique and Multi-Companies Collaboration. Breaking through of several key techniques have been gained, including the product model definition technique based on the latest digital technique, whole airplane design/design modification automation response technique, multilevel concurrent engineering technique, modular design and technique state manage technique, multi-companies and multi-suppliers cooperating develop technique, large assembly butting technique, etc. Moreover, new airplane develop system based on 3D digital technique and multi-companies cooperating develop mode is formed, and it is successfully applied in the large aircraft development, and it has been proved that the design period of the product is shortened by more than 40%. The technique system can be applied to the aeronautics, the astronautics, the large ship, and the other manufacture domain according to its general characteristics. This technique has the comprehensive and profound function to promote our high technique development and improve the entire country's technique and capability.
