Dc, and L/D for various angles of incidence, and against L/D for various values of Lc. Instead of using the actual thickness of the wing the ratio of the span to the mean thickness is used, and will be termed thickness ratio. In this report the term will be applied only when the aspect ratio is… … TfiieHnass ftoffo. On plots 25 to 28 the properties of these wings are plotted against thickness ratio. It was not expected that the points would he on a smooth curve, but it was hoped that there would be enough regularity to determine a mean line, from which the deviation of the points could be…
