Dynamic Flow Control Experiments for Innovative High-Lift Configurations on IHK/M-FLY Programs

Kurzfassung

Meaningful analysis of the performance potentials of dynamic flow actuators for increasing the lift is presently not possible without detailed wind-tunnel experiments on realistic airfoil shapes. The approach of the present work consists of combining advanced flow actuation approaches to delay flow separation on both the high-lift flap and the leading edge of the main wing of a state-of-the-art, two-element airfoil section and performing high-quality flow measurements at chord Reynolds numbers between 2 and 3 Million. The project objective is to demonstrate technology potentials to increase the maximum lift coefficient as well as the maximum angle of attack, and to identify possible interactions between the different flow actuation approaches along with guidelines for future aerodynamic design improvements and needs for further testing.
