General data processing system for multiple wind tunnels

In order to improve the standardization and efficiency of the wind tunnel test data system and improve the reliability and automation of data processing and analysis, a general test data processing system is established for multiple wind tunnels and a variety of test types. On the basis of standardized data processing methodology, processes, symbols and formats, the general system uses the service-oriented software architecture, heterogeneous data storage management, the user defined formula expansion based on dynamic compilation, and the visualized file format editing based on metadata and template. Key problems of the general system are solved, such as the system architecture, processing methods and process control, data flow and file output, etc. In the last three years, 71.2% of test data of 6 wind tunnels in the High Speed Institute of China Aerodynamics Research and Development Center were processed by the general system, covered test types including single and multiple balances forces and moments measurement, pressure measurement, venting measurement, mixed forces and pressure measurement, jet test and some special tests. With the characteristics of being universal, efficient, and open, the general system is a data processing and management solution that worth promoting.
