Web1 Jan 2013 · Thick airfoils also have higher upper surface velocities. The associated adverse pressure gradients cause additional growth of the boundary layer thickness, resulting in increased pressure drag. In case of leading edge soiling also premature flow separation will occur, which increases the pressure drag even further. Web1 Nov 2024 · Kojima R, Nonomura T, Oyama A, et al.
