Abstract: Wind tunnel is the vital facility for aerodynamic evaluation and research, which plays a pivotal role in advancing the development of aerospace vehicles and the construction of an independent flight equipment development system. It is a tangible representation of a nation's scientific and technological capabilities. In light of the ongoing digitisation and intelligence development of equipment, we have outlined the historical trajectory of complex equipment digitisation. With the emergency of the next generation aircraft evaluation requirement, a digital framework for wind tunnel full life cycle research is proposed. Throughout the requirement, design, construction, operation, maintenance, the framework is to solve the current limitation, which include the unstable quality and inefficient design, simple but inefficient maintenance. In the case of low-speed wind tunnels, the typical applications of wind tunnel digital prototypes 1.0 to 3.0 are presented, and the main application scenarios of digital twins, such as wind tunnel state monitoring, wind tunnel virtual test and wind tunnel prognostics and health management, are outlined. Finally, potential research directions of wind tunnel digitisation are discussed, including interdisciplinary-multiscale modeling and silulation, flight performance evaluation and design integration, model and data standard system. Through this research, we hope to provides a suggestion to conduct further development for the construction of a digital control system for the entire life cycle of wind tunnel equipment.
