I'm working on a research project regarding the Bell XS-1, which used the NACA 65-110 airfoil. I haven't been able to find any data on this airfoil, and I'm wondering if anyone knows where I could?
Google "NACA 65-110" and the first entry is airfoiltools.
The NACA airfoils are all designated by a math formula, pop in the variables (65-110) and out comes the shape. 4-digit series 5-digit series and the "6" series are the most popular.(all with standard or modified versions) So all you need is the 6 series formula and a spreadsheet.
The 6 series formula produces what are commonly called laminar-flow or critical-flow designs, they tend to avoid sharp changes in pressure. Laminar flow is only achievable with very smooth construction(no rivets or seams) and good clean flight conditions(bugs and dirt cause much more turbulent flow) However the same basic design due to the mild changes in pressure also have mild changes in local flow speed and so they also work well at increasing the critical mach number which is useful for high-speed subsonic aircraft like the 747-8. (as well as controlling the position of the shockwave when it does form)
