The thicker airfoils did have higher profile drag at higher speeds due to the thickness however.
Acceleration or deceleration in the flow that moves around the cylinder causes significant change to the structure of the boundary layer and, correspondingly, change to the position of the point of boundary layer separation: during acceleration of the flow around the cylinder ([partial derivative]W/[partial derivative][tau]) > 0, the point of separation shifts backwards, causing a decrease in aerodynamic trail width and as a result profile drag caused by viscous forces in the flow (the coefficient of profile drag [C.
Wing drag was calculated as the sum of zero-lift drag, induced drag, wave drag, profile drag and interference drag.
