The data fusion of wind tunnel test, numerical calculation and flight test is an inevitable requirement for the development of new generation aerospace vehicles. However, the application of data fusion is restricted by many factors, such as isolated data islands and low level of equipment intelligence. In this paper, the definition and necessity of aerodynamic CPS is analyzed, and the vision of the integration of CPS and aerodynamic research is described. By construction of aerodynamic CPS, the method of data, process and experiments fusion is proposed, to realize the digitalization of equipment, model and human. Driven by big data, data fusion brings new ideas to wind tunnel test, numerical calculation and flight test, and promotes the research ability in data organization, information value and management.
