摘要

The experimental study of flow around a supercritical profile of Aerospatiale RA16-SC1 fitted with an extrados spoiler was carried out with two dimensional laser velocimetry. The measuring method used is described. A synthesis of the experimental results for three swivel angles of the spoiler (10 degrees, 20 degrees and 40 degrees) as well as for a three dimensional configuration is given. A numerical calculation method of separated flows is adapted to the case of the spoiler and completes the experimental study. The results obtained are compared with measurements of velocity and pressure.
