The article presented describes an approach to active flow control by means of pulsed blowing from the flap shoulder in order to delay turbulent flow separation in low-speed flows. The experiments were carried out on an industrial low-scale high-lift wind tunnel model, a specific landing configuration model employed in the industrial aircraft design process. The results verified the concept of pulsed blowing as a suitable tool for separation control on a complex model at a Mach Number relevant for take-off and landing (Ma = 0.2) and a reasonable Reynolds Number (Re = 1.6 x 106). Lift was increased significantly over a broad range of angles of attack with only moderate energy input necessary.
