Hello CX330 CPA VirtualRelatively big aircraft companies like EMBRAER, Boeing and Airbus quite often develop their own airfoils, in which case their coordinates and drag polars, as well as pretty much any other data, is kept very secret.They will usually publish the name of the airfoil, but I have never come accross useful data on any of the airfoils used in these big aircraft.I think the best thing to be done is to try and match the performance of the aircraft by using an airfoil that you think approximates the shape (mostly the thickness, in percentage) of the one you are trying to mimick.
