This report presents results for CFD computations for 2d airfoil flows with free boundary layer transition. For transition prediction the γ-Reθ transition model is used in combination with the SST k-ω model. Different airfoils and flow conditions are considered to investigate the influence of the free boundary layer transition on the dynamic aeroelastic stability (flutter) of supercritical and laminar airfoils in the transonic flight regime. The results are compared to fully turbulent results. This report presents the results for the milestone 1.1.1 “2d investigations completed” and milestone 1.2.1 “Parameter variation for laminar airfoils and assessment” in work package HAP 1 of the project ALLEGRA.
