Abstract: For the problem that current methods for performance prototype of quantitative description and modeling theory was not yet mature,the functional devision and design procedure for performance prototype were analyzed based on systems engineering method and performance prototype verification process.The performance prototype collaborative design and simulation business was analyzed,and a collaborative performance prototype conceptual modeling method based on ontology meta model was proposed by combining with ontology modeling method.The collaborative conceptual modeling of a hypersonic vehicle was used to show the performance prototype collaborative modeling case,and a performance prototype ontology model library was constructed with Protégé tools which could better solve the lack of multidisciplinary product model output and the problem of redundant information.It could explicitly express domain knowledge and promote the concept of semantic consistent between different areas.

Key words: performance prototype, collaborative modeling, ontology meta model, aerospace products
