Abstract With the development of cloud computing, internet of things and other technologies, collaborative design cloud platform manufacturing mode has been widely used in the field of aviation equipment manufacturing. In this mode, there are semantic heterogeneity and data island problems among aviation equipment digital models, so it is difficult to carry out semantic unified integrated expression. This paper analyzes the data involved in the business interaction of aviation equipment enterprises under the collaborative design cloud platform mode, and describes it in four dimensions. Then, the generation process of aviation equipment digital model is extracted through the whole life cycle business interaction. Combined with ontology theory and meta modeling method, the construction principle and construction process of ontology meta model are analyzed. Combined with the characteristics of aviation equipment life cycle and data types, the aviation equipment ontology meta model for collaborative design cloud platform is constructed. Taking unmanned aerial vehicle (UAV) equipment as an example, the UAV ontology model is constructed through ontology construction software Protégé. The information in the whole life cycle of UAV is expressed with unified semantics, which verifies the correctness of the construction method of aviation equipment digital model proposed in this paper.
