Active Flow Control on an Industry-Relevant Civil Aircraft Half Model

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 ·106). Lift was increased significantly over a broad range of angles of attack with only moderate energy input necessary.
