Abstract : Experimental techniques were employed to determine the coefficient of skin friction drag and the distribution of local frictional intensity for several low drag bodies of revolution with mixed laminar and turbulent flow. The data were obtained as a function of fineness ratio and Reynolds number from experiments conducted in a subsonic wind tunnel under conditions equivalent to incompressible flow. Skin friction drag coefficients were determined first by the indirect method of subtracting pressure drag from total drag. A second more direct method was the determination of local shear distributions and integration over the surface area to obtain total frictional drag. The possibility of inaccuracies introduced by assumptions and agreement between results of the two methods are discussed. (Author)
