Abstract :
A Doppler Global Velocimetry System (DGV) has been developed and qualified at ONERA. It can perform planar three component mean velocity measurements in air flows. Our system was designed with special regards to wind tunnel applications. The technical performance of this system is reported as well as the successful tests in wind tunnel flows. DGV measurements were performed in the flow above a delta wing and the upper surface of a transonic airfoil. A cooperative program with DLR is now established in order to work out a concept for a DGV system for large European wind tunnels
