This video is for the airfoil without flexible flap, i.e., with rigid trailing edge. The weak and widespread jet is oriented prominently in the inclined-upward direction. However, a longer visualization would show the jet-meandering mentioned in section 3 of the main paper. Note: The airfoil casts moving shadow in the upper half of the window.
