Abstract
Over the last decade numerous experimental and numerical studies have been conducted by DLR together with partners regarding the maturation of active flow separation control technologies at low speed high-lift conditions. The DLR-F15 high-lift airfoil has been established as a common test bed for such kind of investigations within the German national framework and in the scope of European Research. The present paper highlights major results of this research regarding flow separation suppression by means of pulsed blowing.
