Flow of Infinite Width Past a Trailing Edge with a Flap

This problem is connected with the aerodynamics of the cruise regime when (in stretched coordinates) the flow around the trailing edge is semi-infinite. The corresponding pattern of the flow and the auxiliary plane £ are depicted in Fig. 8.11, where Y = y//i, X = x/h, Of is the angle of the deflection of the flap (Of = 7гп, 0 < n < 1), and bf is the chord of the flap, normalized by the ground clearance.
