Super NLF Airfoil with Vortex Generators

Or extended run NLF airfoil.

Net drag reduction of 8 % (?) could be achieved. NLF airfoil was redesigned to have a longer laminar section and the aft flow was recovered by using small vortex generators at 75% or 85% chord position.

Some explaining pictures follow. The full text is in AIAA-2003-0211 "Enhanced Airfoil Design Incorporating Boundary Layer Mixing Devices".

Y-axis is the section lif coefficient cl and X-axis is the drag coefficient cd.
