First InVIGO test campaign was successfully carried out in CSTB facilities in December 2020. More than 10 days of wind tunnel tests allowed acquiring a lot of vortex data on around 50 wind/ground clearance configurations.
The 250 kW fan permitted to reproduce required engine flows for all expected combinations of engine intake and crosswind velocities.
Three Stereo-PIV planes, associated with pressures rakes measurements in fan plane, were acquired for every configuration.
All the data will be post-processed and compared to CFD simulations during the first months of 2021.
