 December 7, 2007, 10:09 NACA0010 coordinates with c=100mm #1 said Guest   Posts: n/a Sponsored Links hello dear collegue, i'm going to do a numerical investigation of the effects of geometry parameters on NACA airfoils using cfx. so to creat geometry,i need coordinates (x,y)with cord=100mm. what i have got from "NACA coordinates.dat",that existes in web sites literature, is corresponding to cord=1000m. My question is:how to comput NACA0010 coordinates(for example) but considering: cord=100mm? thank you.
