Abstract: Aiming at improving the product design efficiency and design quality of the structural configuration of large-scale complex product scheme design, the extension integrated design methods of large-scale complex product scheme were researched. The extension ontology conceptual model, the construction framework of extension ontology base, the extension requirement model, the extension matching model and the extension redesign model in the extension design process of large-scale complex product scheme were analyzed, and a framework of extension design mode for complex product rapid design based on extension ontology concept was proposed. By integrating application layer, application tool layer and environment support software layer, the extension integration platform architecture for rapid design of aircraft products based on extension design mode was put forward. The results indicate that the structural extension configuration of complex product scheme design with the characteristics of multi-level, multi-attribute, creativity and complexity is realized by the establishment of the architecture of the extension integrated design platform, and a theoretical and engineering support for the smooth implementation of complex product rapid design is provided.
