Experimental investigations have been carried out with the two-dimensional DLR-F15 high-lift wing-section model in the Cryogenic Wind-tunnel Cologne DNW-KKK to differentiate between the influence of Mach and Reynolds numbers on the stall behavior. Because of the cryogenic environment, Mach and Reynolds numbers have been varied independently between M = 0.1 0.25 and R e = 1.4 × 10 6 15.6 × 10 6 . The investigation covers two- and three-element configurations at various slat and flap settings and two different slat shapes. The focus of the investigation is to identify conditions of turbulent leading-edge stall, shock-related lift limitations, and flap separations and their influence on achievable maximum lift coefficient.
