Combined Active Separation Control on the Leading Edge and on the Trailing Edge Flap of a Slatless High-Lift Configuration

This paper describes experimental investigations into active flow control applied at the wing leading edge and at the trailing edge flap of a slatless high-lift wing configuration. The experiments were conducted on an airfoil, which is used extensively by different German and European research programs. The experimental results presented in this work demonstrate successfully the effectiveness of multi-locational active flow control to increase c(l), c(l,) (max) and Delta alpha(max) in combined mode.
