Abstract: | A DGV system using a continuous wave Argon laser and an optical arrangement with a single intensified camera has been set
up at the ISL blow-down supersonic wind tunnel. The first tests have been performed over a 12.5° 2D wedge at a freestream
Mach number of 2. A mean velocity field has been calculated from 28 individual measurements. When compared to the theoretical
velocity distribution, deviations of 8 % to 15 % have been obtained. Preliminary tests have also been performed on a missile-like
model equipped with a lateral jet system. Individual as well as mean velocity fields are presented. |
