Test data correlation study of aerodynamic model CAE-AVM in European and Chinese wind tunnels

The aerodynamic validation model CAE-AVM cruise and high-lift configurations were tested in 2013 and 2018 at DNW-HST high-speed and DNW-LLF low-speed wind tunnels in the Netherlands, and a database of Mach number 0.85 civil aircraft has been created and opened for common research. In 2022 and 2023, the same high-and low-speed test models were selected for the correlation studies at the FL-62 transonic and FL-19 low-speed wind tunnels in China. Through comparative analysis of forces, pressure, and wing deformation data, good tunnel to tunnel correlation is recognized. Test data shows that the overall consistency of the aerodynamic forces and moment in European and Chinese wind tunnels is very good. The wing sectional pressure distributions and wing deformation data measured in high-and low-speed tests coincide with each other reasonably well. For some slight differences such as the shock wave position, wing deformation during the high-speed test, and the effect of different dummy setup on the low-speed support interference correction, possible reasons are analyzed with the parameters of the test setup, instrumentation and tunnel flow fields. The suggestions to the criteria for aerodynamic standard model test are provided.
