Do you really want XFOIL to be clever and use this reduced distance as the new "chord"? Surely not -- it will really complicate intepreting the deflected-flap polars with the zero-flap polars, because they would need to be rescaled by. The 4-digit-modified-series airfoils are designated by a 4-digit num-ber followed by a dash and a 2-digit number (such as NACA 0012-63). Sign in - Google Accounts.

Also useful is The Incomplete Guide to Airfoil Usage compiled and maintained by Dave Lednicer. A few important assumptions must be stated when using this tool:. The flow of air (or any fluid) over the airfoil results in an aerodynamic force (per unit span) on the airfoil, denoted by R. Then the effects of the relative thickness of airfoil on aerodynamic performance are explored, using the above numerical method, by simulating flows around airfoils of different relative thicknesses (12%, 14%, 16%, 18%), as well as different locations of the maximum relative thickness (x/c = 22%, 26%, 30%, 34%), at a low Reynolds number of 5.
