Book excerpt: It was found that at positie angles of attack the vortex sheet assumed a shape which was initially bowed upward but flattened out downstream before the rolling-up process had progressed to an appreciable degree. A comparison with theory showed that an acceptable approximation tothe downwash distribution within the distance surveyed could be obtained if the vortex sheet were assumed to be flat and the spanwise vorticity distribution were assumed to be that of the wing.
